Different Types of Corrugated Cardboard and Their Uses

Corrugated Cardboard Fluting Types

Corrugated cardboard fluting construction helps support a lot of weight and provides great cushioning. These curved arches also serve as insulation from sudden temperature changes.

B-flute cardboard has 49 flutes per foot and has lower arch heights than E-flute material. It has good crush resistance and provides a stiff, flat surface for printing and die cutting.

Type B Corrugated Cardboard

In the most basic form of corrugated cardboard, there are two liners and a fluted center sheet. The peaks and valleys of the fluting offer load-bearing and protection qualities, while also allowing for an excellent printing surface.

The most common of these is the ‘B’ flute, which has excellent crush and puncture resistance as well as good printing characteristics. It’s great for inner packaging components and is often used to protect metal or glass items during transportation.

It is possible to combine the different types of flutes, known as ‘Double Walled’ material, which is typically reserved for more specialist applications. However, this comes with additional costs and increased environmental impact. Additionally, while EB-flute is very strong and offers high levels of protection, it uses twice as much material as single-wall fluting which increases the price and carbon footprint. Consequently, it’s only really suitable for use when protection is paramount. Moreover, it’s not ideal for lightweight retail items.

Type E Corrugated Cardboard

If you are interested in creating a corrugated box, it is important to understand the different types of flutes. Fluting affects the strength and durability of your packaging, as well as how it will print. The thickness of the flute also determines its ability to withstand pressure.

F and N-type micro-flute are becoming more popular because they offer a smoother printing surface than E-flute and still provide a high amount of crush resistance. They are also very good at providing support for heavier items, such as bottles and jars.

Adding an extra wall of cardboard increases the load-bearing capacity and makes your carton more resistant to impact damage. This type of box is known as a triple wall and is typically used for items that are extremely valuable or require a very high level of transit protection. BC and EB flutes are a combination of B and C flutes, which means the inner wall offers great transit protection while the outer layer provides excellent printability.

Type F Corrugated Cardboard

The most common of all flute types, C flute cardboard is crust-resistant and a good choice for transit packaging. It has a high stacking strength, and it provides an excellent print surface for branding.

The thinner construction of type E flute cardboard helps to reduce storage space and is ideal for printed retail cartons. It has excellent crush resistance and a flat surface for printing, although it would not be suitable for shipping packaging due to its thinness.

R flute is a newer style of fluting that has smaller and closer flutes, allowing for more accurate folding and a higher quality printing surface. It is a good option for smaller, lighter items and is typically used in conjunction with B flute for greater rigidity and strength. It is also available in a 7-ply construction which is used for pallet packs. This consists of three pieces of fluting board and four pieces of linerboard. It is strong enough to be used as a substitute for wooden crates.

Type C Corrugated Cardboard

All corrugated cardboard has a liner and a fluted centre. The fluting consists of curved arches that are designed to give the board strength and resilience. These arches are positioned in different ways, creating the various board types. Each type of flute has a specific take-up and bending resistance, which are important factors for packaging designers when designing boxes for shipping products.

The most common flute is the C flute. This type is a good choice for most packaging because it offers a great print surface, and has a strong take-up and bending resistance. The only drawback is that it doesn’t have as much compression strength as B flute.

Single-Face corrugated has only two layers – one is the lining, and the other is the fluting. This makes it less durable than other types of cardboard, but it’s cheap to produce and works well for inner packaging components that provide additional cushioning. It can also be printed on using a variety of methods, including lithographic and digital printing.

Factors Affecting Flute Tone and The Materials Used

How Flutes Are Made

Several factors contribute to the tone of a flute. The first is the type of wood used. Softer wood tends to absorb sound vibration. This can create a dull sound.

Flutes made from grenadilla wood produce a rich timbre that is both captivating to listeners and satisfying to play.


Firstly, choose dense wood that is suitable for making a flute. A flute can be made from a single piece of timber, but it is often more economical to make it in three pieces, with a head joint on the top and middle and the body of the instrument.

Then mark the locations for the tone holes on the body of the flute using a plan you have designed (or by eye). Then drill the holes, being careful not to go too far in as it could affect the sound of the flute.

Next, pad corks are cut to fit the tone holes and felt is cut to fit over them. A spring is attached to provide tension to keep the pads pressed firmly against the tone holes. All this is coated with a protective coat of polyurethane to help the flute resist moisture that would cause the pads to swell and no longer fit the tone holes.


The flute is a metal tube, so it can be bent and shaped in various ways. Any changes in the acoustic characteristics of the flute can affect its sound and playability, so it’s important to make sure all parts fit together properly.

The keys for the flute are made from a group of connected components that are soldered together. This is done with a solution containing chemicals that protect the underlying metal during soldering. The resulting keys are then buffed and polished to smooth out any rough edges.

Flutes used to be made from wood, but there were good practical reasons for changing to metal. For example, wooden flutes can develop a number of problems, such as bore distortion, which can distort the tone holes and create leaks. Metal flutes, however, do not suffer from these problems.

Stainless Steel

Stainless steel is a hard, durable material used in construction projects. It’s known for its corrosion resistance and aesthetic qualities. It’s also very cost-effective. Many manufacturers use this metal for their flutes because it produces a sweet, expressive sound that is similar to silver but not as costly.

Unlike wood, metal is also air-tight. It’s less porous, which is why metal instruments often have a more consistent sound than wooden ones.

A specialized end mill is designed for stainless steel to avoid work hardening and minimize the effects of heat on the material. These tools have unique helix angles and optimized flute geometry that allows them to cut the metal quickly without damaging the material. This is important for maintaining the quality of the flute’s finish. It also allows the machining process to be completed in a shorter period of time. Using a higher number of flutes will give you extra chip clearance but it’s still important to keep the feed rate reasonable.


The flute is traditionally made of brass, an alloy of copper and zink. This metal is pliable, durable and relatively inexpensive. It’s silvery-white and light in appearance, but can be plated with silver for a more mellow sound. Student and intermediate flutes are usually solid silver (sometimes called sterling silver) while professionals use gold and various combinations of these metals.

The modern flute was developed by Theobald Boehm in the early 1800s. He worked out the best size and position for holes and designed keys that made it easier to play. His improvements also led to composers including flute parts in their music again.

A short version of the flute is often used for classical music, the piccolo. This instrument is half the size of a standard flute and sounds very different, with an earthier undercurrent. It’s sometimes made of wood, but most commonly of silver or gold. All flautists will have to learn to use one of these instruments at some point.

No Holes vs Open Holes: Debating the Best Flute Design

A Flute With No Holes Is Still a Flute

A flute with no holes is still a flute. However, there are some differences that need to be considered.

Open hole flutes encourage a less ergonomic hand position that can cause problems with some students. If a student has trouble with this then it may be better to bung up the G key holes (with plastic bungs provided) and remove them one at a time.


Unlike the recorder (which resorted to half-covering) Boehm’s innovation allowed flute players to play any key without relying on fingering “tricks”. The result was that a single pressed note could be delivered at many different positions along the scale, even those that would have been difficult or impossible with just a single hole.

There is a debate as to whether or not it’s best for kids to have open holes on their student flutes, but it really depends on how well the kid plays. Most kids that have the proper hand positioning and can cover everything without having to do any tricks, don’t notice a difference at all.

In addition, opening up the keys forces a player to fix any mistakes that might otherwise go unnoticed – such as crooked fingers or protruding thumbs. This also allows students to practice the physics of finger placement and the eticate of playing flute, which improves their overall technique and sound as they get older.


A flute’s mouthpiece is a curved piece of metal that the player places their lips over, allowing them to control the flow of air across the embouchure hole. It can be made from a variety of materials, but the most popular is nickel-silver or silver.

It also has a small chamber that receives the player’s breath, called the Slow Air Chamber (SAC). This is an important part of the overall flute because it acts as an air bladder to even out the air pressure as it travels down the flute.

Many acousticians, such as Dayton C. Miller and Arthur Benade, consider the plateau model acoustically superior to its open hole counterparts. They consider the open holes to be a major flaw, ‘the one acoustical crime that has been perpetrated against the Boehm flute,’ in Miller’s words. However, an accomplished flautist can compensate for the sharpening effect of open holes with other techniques such as playing very softly or using certain alternative fingerings.


The rods are long, round metal bars that travel down the body of the flute and mount the keys which rotate to allow them to move up and down. These are what give a flute its range – the energy from the fingers and springs on the keys gets transferred down these rods to the rotary key mechanism.

The ridged top section of the body is called the barrel and usually features the maker’s name and model number. Below that are the smallest sections (usually two on the left and three on the right) and then thirteen holes operated by the keys. These are covered by pads which can be damaged easily and should be checked regularly by a qualified repairer to ensure they remain in good condition.

When holding the body and foot joint together it’s important to avoid the rods and keys as they can bend over time and affect intonation. To help with this, students should hold the foot joint so that it is pointing away from them.


There is still a lot of debate about whether an open or closed hole flute is “better”. This really depends on the type of music the student wants to play and their own personal preference.

Closed hole flutes have no tone holes at the top of the keys and have a more simple fingering. This type of flute tends to be more accurate in the lower octaves because it requires less adjustment. It also encourages students to fix their sloppy technique as they have to put more pressure on the rods and keys to make them function.

An open hole flute has a number of tone holes at the top of the keys. The flute maker cuts the tone hole into the tube of the flute and then solders it to itself. This introduces a small amount of additional metal into the sound wave and may slightly change the resonance. However, this change is very slight and usually not noticeable to the player.

The Flute’s Role in Zelda 2: Side Quests and Fast Travel

The Flute in Zelda 2

The Flute is a musical instrument used to summon a duck that transports Link to certain locations in the game. It can also be used to open up heart containers and Secret Money areas in the second quest.

Players can obtain the flute by presenting 10 Sunset Fireflies to Pyper at Highland Stable. Once the player does so, the statue bird shatters, revealing a real bird inside that can be played to warp to different locations in Hyrule.

The Flute Player’s Plan

One of the more heartwarming side quests in Tears of the Kingdom, The Flute Player’s Plan is a simple task that sees Link help a flute player impress his cheery little friend. To start this quest, Link should head to Outskirt Stable, southwest of Lookout Landing, and speak to the conductor Mastro. He’ll explain that their flute player, Pyper, has gone missing. One of the stablehands will suggest that he may have accompanied his little sister to Highland Stable in the southeast.

Warp to Highland Stable in Faron Grasslands and you’ll find Pyper hiding up in a tree near the stable, playing his flute. Speak with him to start the quest, and he’ll ask you for ten Sunset Fireflies. Once you’ve collected them, hand them over to him, and he’ll instruct you to bring Haite to his tree at night to see it glow. Do so, and you’ll have completed this quest. You’ll also receive a Big Hearty Truffle, which fully heals hearts and opens up a heart container in the game.

The Flute Boy

When Link first meets the Flute Boy in the Light World, he hears him play his flute in a grove. The animals flock to the apparition, but they disappear as soon as Link gets too close. This boy is shown to be a very kind person who cares about nature and the animals in it, similar to Gulley from A Link Between Worlds.

In ALTTP, players can find the Flute Boy in the Pgos Woods area located north of Highland Stable. He asks Link to get him 10 Sunset Fireflies. Upon completing this task, he rewards Link with a Big Hearty Truffle, which fully heals the player, and also adds yellow hearts when cooked into food.

The Flute Boy will then go back to the grove in the Light World where he plays his flute for the animals. He will then tell Link where he buried his instrument and that he would like to see it played one more time before he dies.

The Flute in the Light World

One of the most interesting side quests in Tears of the Kingdom involves a flute player who can be found all the way down at Highland Stable Well in Faron Grasslands. The flute player, who is named Pyper, has a quest for Link that is required to serenade Kaysa in the Great Fairy Quest.

When Link gives him the Flute, Pyper reveals that he has been wandering into a parallel world similar to the Haunted Grove, and he asks for a favor – he wants to hear his father play his flute once more. If he doesn’t get that one more time, the Flute Boy will petrify into a tree in the Dark World.

Play the Flute in a grove to make a bird appear and fly you to a nearby location on the map. This unlocks a new fast-travel option in the game, which is available to use by simply playing the flute anywhere outside.

The Flute in the Dark World

The flute has a variety of uses in Zelda 2. It is one of the best weapons for reducing bosses in dungeons to make them easier to kill. It also opens up a number of “secret” money areas and heart containers.

The Flute Player was originally a boy from Kakariko Village who was warped to the Dark World. When Link visits him at the Light World’s equivalent of the Haunted Grove, he asks for help finding his flute which he has buried in the area. He then gives Link a shovel so he can dig it up.

When Link plays the flute in front of the Weathercock in the center of Kakariko village, the Flute Boy’s pet bird breaks out and flies away. From that point on, if Link plays the flute in the overworld of the Light World, the bird will fly him to one of eight locations. This is a great way to get around the map quickly.

Choosing the Right Corrugated Cardboard Flute Thickness

Corrugated Cardboard Flute Thickness

If you’re planning on buying corrugated cardboard, it’s important to know the type of fluting. This will help you select the right material to meet your needs and ensure that your packaging is both strong and high quality.

For example, C flute has great compression strength but is prone to crushing if it’s overloaded. A better option is EB, a double-walled material that combines both B and E flutes.


Corrugated fiberboard (often referred to as cardboard) is made from two linerboards sandwiching a middle sheet of wavy material known as fluting. The flutes make the box strong, and also serve as an insulator and cushion. Fluting comes in a variety of heights, which determine the type of shipping strength the box can offer and how easily it can be printed.

The most popular flute size is C, which has 39-43 flutes per foot and is about.1875 inches in height. It offers excellent crush resistance and stacking strength for lightweight products, and its flat surface makes it ideal for printing and die cutting.

The B flute has 47-48 flutes per foot and is about.125 inches in height. It has a lower height than the A flute and is ideal for e-commerce packaging, due to its superior printability and stacking strength. It has good crush and puncture resistance, but is not ideal for shipping rigid or large items.


Corrugated cardboard has a series of flutes within it, which offer cushioning protection and stacking strength. These flutes vary in height and spacing, making them suitable for different types of products and boxes. A very fine material flute denoted as E offers light packaging, while a coarser flute is good for heavier products like furniture and glassware.

The flexographic or lithographic printing process used to print on the flutes of corrugated cardboard creates beautiful graphics and messages for your business. These boxes are a perfect way to promote your brand and make it look professional. They can also be made into a one-piece folder box, making them easy to open and assemble.

The B flute is commonly used for POP displays and folding inserts. It has decent stacking strength, excellent crush resistance and good printability. Its flutes are slightly wider and closer together than C and E flutes, making it ideal for smaller products. This combination of stability and printability makes it an excellent choice for e-commerce mailers and other double wall corrugated products.


Flute thickness is an important factor when selecting a flute profile for your custom packaging. The size of the flutes directly impacts the compressive and cushioning strengths of the box, as well as its take up capabilities. The various profiles offer different advantages, but each has its own unique benefits.

The E flute has a very thin board profile, which helps reduce outer box dimensions and storage costs. This flute type also offers excellent crush resistance and a flat surface that allows for high-quality printing. This flute is commonly used for consumer products packaging.

The B flute has a thicker board than C, and it provides superb crush resistance. It also has a good print surface and is ideal for partitions inside custom boxes. This type of flute is often used for transporting glass, cans, and furniture items. It can also be combined with the E flute to create a double-wall material, which offers better protection and a superior printing surface.


This double-wall fluting material is a good choice for box designs that require extra protection during shipping. Its thickness offers good crush resistance and provides a strong, flat surface that’s ideal for printing high-quality images and texts. It’s also less expensive than A-flute and a great choice for bulk orders.

Developed for packaging canned goods, B flute is also popular as a counter display box. It is crust-resistant, and its thin construction reduces outer box dimensions and saves storage space. It’s also a good option for inner packaging such as pads or dividers, and it prints well.

Flutes are the wave-like lines adhered to layers of linerboard that give corrugated cardboard strength and structure. They’re available in different sizes, known as flute profiles, ranging from A-flute (the largest) to F-flute and below (microflutes). Each profile has its own advantages, depending on the weight and fragility of the product being packaged. Larger flute profiles provide greater vertical compression strength, while smaller ones offer superior printability.

Challenges in Flute Etudes: Precision, Articulation, and Rhythm

Flute Etudes PDF

Rhythmic precision, facility and clean articulation are key challenges in this etude. Be careful not to miss the dotted eighth sixteenth and triplet rhythms. Slurs are also a phrase indication and should be articulated precisely.

The chromatic passages with large intervals and syncopated articulation groups will require a good deal of attention to detail. Utilizing side C and fork fingering will help the fingers avoid sliding in these sections.

Etude 1: B Major

Rhythmic fidelity is paramount in this playful etude. The performer should use the metronome to help establish a clear division between the sixteenth note sixtuplet figures and thirty-second notes.

When articulation markings such as tenuto appear, the performer should strive to play them with length and weight. It is also important to treat the slurs as instructions for how to phrase this music.

Etude 2: Db Major

This fun etude requires excellent articulation and rhythmic control. It is also essential to work on a consistent air stream with the right embouchure to produce a full and characteristic tone.

There are several slurred passages in this etude that require a light and even sound. Practice slurred scale patterns and arpeggios (major, minor, dominant seventh, fully diminished) to develop consistency in fingerings and tone.

Etude 3: C Major

Printing is not supported on iOS devices. To print your purchase, please use a desktop computer.

Master flutist Amy Porter has reworked the famous Cyrille Rose etudes for flute, allowing students to reap the benefits of these pieces that have helped clarinetists for generations. She has also raised octave placements to better fit modern flute ranges. A valuable practice and recital piece.

Etude 4: F Major

Unlike many of the other pieces in this set, this one is more musically difficult than technically challenging. The main difficulty lies in the incredibly complicated arpeggios that span a huge number of notes in both hands.

Rolling chords in both hands abound, sometimes reaching a twelfth in size. The right hand must play these quickly while maintaining a fluid sound and proper rhythm.

Etude 5: G Major

This fun and musical etude calls for a fast, consistent air stream with beautiful tone. Students should feel comfortable pushing and pulling the tempo to make artistic choices around breath marks and before fermatas.

Focus on playing with a large beat emphasis, especially when playing the dotted eighth note rhythms in the first bar. All grace note figures should be performed on the beat to delineate rhythmically between duple and triplet figures.

Etude 6: A Major

Clair Omar Musser’s Etudes are a staple in four-mallet literature. Almost all marimbists have at least one of them in their repertoire and learn them all.

Liszt’s etudes on Paganini are some of the hardest piano pieces ever composed (although he did thin them down and remove some of the outrageous technical difficulties). This particular piece requires a lot of fluidity and large jumps while staying delicate.

Etude 7: Bb Major

This etude presents many musical challenges and should be played with beautiful tone, accurate rhythm and attention to the accidentals. It is especially important to practice the chromatic passages, large intervals and syncopated articulation groups.

Pay attention to the articulation markings; slurs should be played with a tongued articulation and notes with a marcato marking should be emphasized with more weight than surrounding notes.

Etude 8: C Major

Etudes are a great way to improve your skills. They focus on specific things like tone and technique. They are also short, so they can be done in a limited amount of practice time.

Each practice session, circle the difficult parts of an etude for special attention. Work over these areas using a variety of techniques, such as starting with longtones and progressing to subdivisions.

Etude 9: Db Major

This etude starts with a dramatic chord and quickly moves into tumultuous sixteenth note runs in both hands. The left hand is rather simple compared to the right, but this piece still requires considerable virtuosity.

This etude, like most of the others in opus 25, requires excellent legato from the performer. Obtaining a fluid and even hand motion without losing the intended musicality is one of its greatest challenges.

Etude 10: F Major

Chopin wrote this etude to help strengthen and train the fingers and hands. Its nickname, the Ocean etude, comes from the fact that the right hand accompaniment is almost entirely played on black keys.

The most difficult part of this etude is playing the sweeping sixteenth-note progression in the left hand. This must be done with a firm and fluid hand motion in order to achieve the desired legato.


Chamfer Tools for Various Machining Styles and Materials

6 Flute Chamfer Tool

Chamfering and beveling are common operations that can be found in every machine shop, assembly floor, or hobbyist’s garage. These sloped surfaces protect hand injuries, aid assembly, and help part aesthetics.

Harvey Tool offers a variety of chamfer cutters for various materials and machining styles. These include pointed, flat end, and center cutting cutters.

Solid Carbide End Mills

Solid carbide end mills are harder and more wear resistant than high-speed steel and provide a sharper cutting edge that lasts longer than tools made of other materials. They are available in a variety of sizes, flute counts, geometry and coatings.

Choosing the right solid end mill starts with thoroughly evaluating the operation and the material to be cut. Flute count, helix angle and geometry all factor into the cutter’s performance and cost.

For example, a high helix angle reduces tool deflection by transferring stress vertically rather than horizontally. It also produces a greater shearing action, which can increase speeds and feeds by improving chip control.

A titanium nitride (TiAlN) or aluzinc coating resists corrosion and dissipates heat to prevent burning, which helps prolong the life of your cutter. These coatings are ideal for high-speed cutting and dry machining.

Carbide Tipped End Mills

There are many different end mill options available for use in a variety of materials and operations. Some of the more common styles include pointed, flat end and centre cutting. Pointed end mills have a sharp tip that can be used for deburring or chamfering in narrow grooves and slots. Flat end mills are suitable for side and face milling, plunging and slotting.

End mills come in a range of flute counts and types, with the number of flutes being an important consideration. For example, a 2 flute style allows for quicker chip evacuation and reduces chatter in hard materials. A 3 flute design provides the best balance between chip evacuation and strength.

Helix angles can also have a significant effect on how well an end mill performs. For example, low helix end mills are able to cut more aggressively but will generate much more heat, which can lead to tool failure or poor surface finish.

Solid Carbide Back Chamfer Cutters

These cutters are used to chamfer the back side of slots, through holes and part projections. They have a low profile design and a greater radial projection than end mills, and they cut faster for quicker part finishes.

These chamfer cutters have a brazed carbide head, with a tip that comes to a point. They are uncoated and are available in a variety of diameters.

They can be used in a revolving operation to chamfer both sides of a workpiece with one pass. This saves time and reduces the number of tools required.

Designed to provide up to 1/16″ top face chamfer on plastic sheets or parts. The finished side edge eliminates peeling and improves gripping on sheet or workpiece.

Use with DCNS drills with a chamfering holder to perform drilling and chamfering in one operation. Standard XCGT inserts mounted on the CHAMRING body provide 3 standard chamfering angles: 30deg, 45deg, and 60deg.

Carbide Spot Drills

Carbide spot drills leave a small divot to pinpoint the center of a drill before plunging. This prevents the drill from “walking” during the holemaking process and improves overall accuracy. Some machinists also use these tools to chamfer the top of drilled holes, so screw heads sit flush with the part once inserted.

These spot drills have short flutes and a stub overall length for maximum rigidity. They can be used on a variety of materials, including harder steels. They are available with 90, 120, and 142 degree included angle points and uncoated or ALTiN coated.

A spotting drill is often used with twist drills to ensure accurate hole positioning and eliminate chatter during the machining process. They can be machined together to form a spotting hole and a flat bottom counterbore in one work step. However, a spotting drill may not be adequate to retain holes in an uneven or irregular surface, so machinists should use a flat bottom counterbore for more demanding applications.
