What type of cardboard

These boxes are flat and easy to carry where flaps can be easily secured using staples or tapes. The various types of Slotted boxes are based on the varying length of the inner and outer flaps. This is the most common style of corrugated box. In this type, the inner flaps are shorter and have gaps in between, whereas the outer flaps are half of the box width, making them meet in the middle when folded.

This is also similar to RSC; however, the outer flaps overlap by at least one inch, instead of meeting at the middle. One can use this design in the event, the length of the box is significantly larger than the width. Similar to RSC, except the fact that the outer flaps completely overlap each other when closed. This type of box has both inner flaps and outer flaps meet at the center.

Same as CSSC but the length of the box cannot be more than the twice the width. This is same as CSSC but the outer flaps completely overlap each other when closed. Telescope box consists of two parts. It includes a top piece which is the lid and a bottom piece to store the item. Folders are basically a piece of cardboard which could have multiple parts.

The base is flat where the item sits and the rest of the cardboard will have scored which will fold around the items. There is more to corrugated cardboard boxes than meets the eye! Cardboard boxes have a different science altogether and the shipping industries give great attention to the type of the box used for a particular product.

E-commerce industries too give attention to the type of boxes used for a specific type of product to prevent extra charges on box weight as well as dimension. Companies can save a significant amount of money simply by using the right type of cardboard box for the right type of product.

Next time you consider buying a cardboard box to ship your items or to move your stuff, you know exactly what to purchase and how to use. Here goes a comprehensive guide to cardboard and corrugated cardboard boxes.

Therefore, if you are using a corrugated board that has a gsm Kraft paper liner, you will often see it referred to as K. Besides the varying paper weights and types, the type and number of fluting must also be considered. At a basic level, a corrugated board is made up of the two liners, plus the single fluting. You can see a diagram indicating this below. This effectively adds extra rigidity and strength, making it suitable for packaging heavier items and adding additional protection for items that may more delicate or expensive.

Finally, if the items you are shipping are particularly heavy or large for example automotive parts, industrial equipment etc. As the name suggests, this adds another section of fluting and additional liner. Also referred to as Tri-Wall which is the brand name of the manufacturers too , you can see a basic diagram of this below. The final aspect of the corrugated board that can affect its performance and weight and cost , is the flute type.

This can offer a rigid structure perfect for heavier items, whilst also allowing an improved aesthetic outer appearance and printing surface. The flute itself is usually manufactured from a waste based fluting WBF — i. Again, this list is not exhaustive, and is complicated by the fact that many producers of corrugated material make very similar products which are given arbitrary names and are exclusive to that manufacturer. All of this information allows you to create an abbreviation that describes the type of board being used.

For example, if your material grade was using a gsm Kraft outer liner, a gsm Test inner lining, and a B fluting, this would be written as…. Similarly, a Test outer lining, plus a Test inner lining, with an E flute, would be described as….

This terminology would be easily understood by virtually any packaging manufacturer or at least should be , and also allows you to fully understand the type of material your cartons are manufactured from. As such, the below information provides a little more detail on each of the most commonly used flute types. E flute is approximately 1mm to 1.

This not only gives it excellent compression strength and crush resistance, but also means it provides a high quality surface for printing. As a result, it is commonly used smaller cartons, where good quality print is required, plus die cutting applications. B flute is amongst the most commonly used types of cardboard used for packaging applications. Being 3mm in thickness, it is exceptionally versatile and can be used in both die cutting and regular case-making processes.

Between 3. This means it provides better stacking strength when used for lightweight products. Being 6mm to 7mm in thickness, this double wall material combines both B and C flutes together. This gives a good all round performance, making it common for producing shipping boxes that offer a higher level of transit protection.

Around 4mm to 4. Due to utilising both a very fine E and relatively large B flute, this grade provides an excellent balance between transit protection, strength and print finish.

As it is possible to vary a number of parameters when specifying the board type for packaging — such as paper weights, flute types and number of walls, it is actually possible to achieve similar performance with different board grades. However, there are typical performance guidelines for the varying corrugated board grades that are often quoted.

Backing Liner — A compressible paper material which, compensates for any irregularities on the surface which is sealed. This compressible material usually pulp or news board is usually adhered to the liner and provides a better finish appearance , water resistance and extra strength. Board grade — A grade given to corrugated board based on three elements; firstly, the weight and type of outer liner, secondly the type of flute and thirdly the weight and type of inner liner.

Carton Board — Carton Board is stiffer and thicker than boxboard. This is necessary since during shipment a corrugated box or any other packaging may be exposed to various forms of stress such as mechanical vibration, shock, and thermal cycling, to name a few.

Packaging engineers study environmental conditions and design packaging to mitigate the effects of anticipated conditions on the goods being stored or shipped. From basic storage boxes to multi-colored card stock, cardboard sometimes misspelled card board is available in an array of sizes and forms. A term for heavier paper-based products, cardboard can range in manufacturing method as well as aesthetic, and as a result, can be found in vastly different applications.

What is cardboard made of? It can also contain recycled materials in the inner or central liners of double-walled cardboard. Recycled materials, however, take less energy to manufacture into cardboard. This guide will present information on these main types of cardboard boxes and provide a few examples of each type.

In addition, a review of cardboard manufacturing techniques is presented. Half slotted containers, on the other hand, only have flaps on the bottom to leave an opening at the top. For more information on other types of boxes, consult our Thomas buying guide on different types of cardboard boxes. To learn more about other forms of packaging, see our Thomas buying guide on types of packaging. Paperboard is typically 0.

The manufacturing process begins with pulping, the separation of wood hardwood and sapwood into individual fibers, as accomplished by mechanical methods or chemical treatment.

Mechanical pulping typically involves grinding the wood down using silicon carbide or aluminum oxide to break down the wood and separate fibers.

Chemical pulping introduces a chemical component to the wood at high heat, which breaks down the fibers that bind cellulose together. There are approximately thirteen different kinds of mechanical and chemical pulping used in the U.

To make paperboard, bleached or unbleached kraft processes and semichemical processes are the two types of pulping typically applied. Kraft processes achieve pulping by using a mixture of sodium hydroxide and sodium sulfate to separate the fibers that link cellulose. If the process is bleached, additional chemicals, such as surfactants and defoamers, are added to improve the efficiency and quality of the process.

Other chemicals used during bleaching can literally bleach the dark pigment of the pulp, making it more desirable for certain applications.

Semichemical processes pre-treat wood with chemicals, such as sodium carbonate or sodium sulfate, then refine the wood using a mechanical process. It also takes place at lower temperatures and under less extreme conditions. Once pulping has reduced wood to wood fibers, the resulting dilute pulp is spread out along a moving belt.

Water is removed from the mixture by natural evaporation and a vacuum, and the fibers are then pressed for consolidation and to remove any excess moisture. After pressing, the pulp is steam-heated using rollers, and additional resin or starch is added as needed. A series of rollers called a calendar stack is then used to smooth and finish the final paperboard. Paperboard represents a paper-based material that is thicker than traditional flexible paper used for writing.

Any size, shape or color cardboard can be recycled. Each time we recycle corrugated cardboard, the fibers holding it together get a little bit shorter. The result is the cardboard gets slightly thinner each time we recycle it. When the fibers become too thin to create strong corrugated cardboard, they are then used for a class of cardboard called paperboard. Paperboard or chipboard boxes are used for cereal boxes, cake mix boxes and cases of pop.
