Corrugated Cardboard General Information.
There are various types of corrugated cardboard and wave types that serve different purposes. In the production of these genera, ondule produced at various wavelengths is used.
Single-Faced Corrugated Cardboard: Corrugated
Single-faced corrugated cardboard, that is, corrugated, is a type of corrugated cardboard that occurs when only one face of a corrugated sheet is covered with a flat sheet.
Corrugated cardboard is obtained by gluing paper to one side of the ondule and corrugated cardboard by gluing paper to both sides. Double-wave corrugated cardboard and three-wave corrugated cardboard, i.e. triplex, are produced by combining more than one tensile of various wavelengths by gluing paper to their surfaces.
Single-Wave Corrugated Cardboard: Single-wave corrugated cardboard is a kind of corrugated cardboard that occurs when both surfaces of a corrugated sheet are coated with a flat paper sheet.
Double-Wave Corrugated Cardboard: Double-wave corrugated cardboard is a kind of corrugated cardboard that occurs by covering the lower and upper surfaces of corrugated sheets glued to the lower and upper surfaces of a flat sheet with a flat paper sheet.
Three-Wave Corrugated Cardboard: Three-wave corrugated cardboard is a kind of corrugated cardboard that occurs by Decking the bottom and top of three corrugated sheets glued to two flat layers between them with a paper flat layer.
Double Wave Combinations: E+B/B+A/B+C
Three Wave Combinations: E+B+B / B+C+C / A+C+B / C+B+E
Corrugated Boards According to Wave Types.
Coarse Wavy Corrugated Cardboard - A Wave:
The number of grooves per meter is 104-125, corrugated cardboard with a groove height between 4.5 mm and 4.7 mm. Dec.
The fact that it has thick walls depending on the height of the groove allows it to carry loads very well vertically and to provide very good cushioning because it can be easily crushed horizontally.This breed, whose surface is weak to crushing, does not give a smooth printing surface due to the large wave December. A wave is used as an internal percentage in double wave combinations.In this way, the shocks to the product inside are absorbed.
Thin Wavy Corrugated Cardboard - B Wave:
The number of grooves per meter is 150-184, corrugated cardboard with a groove height between 2.1 mm - 2.9 mm. Dec.
It is the most common breed to use.Despite its durability in carrying vertical loads due to the low wall thickness,the surface is quite resistant to crushing due to the higher frequency of waves.Again, depending on this quality, it works quite well in printing.
Medium Wave Corrugated Cardboard - C Wave:
The number of grooves per meter is 120-145, the groove height is corrugated cardboard with a Decking height between 3.5 mm - 3.7 mm.
This type of wave, which occurs after A and B waves and carries the good properties of both, is a good carrier and gives good results in printing.This genus replaces the A wave over time.
Micro Wave Corrugated Cardboard - E Wave:
The number of grooves per meter is 275-310, the groove height is corrugated cardboard with a Decking height between 1.15 mm-1.65 mm.
The E Wave, which has excellent surface crush resistance due to the large number of grooves in the meter, gives the best results compared to all other types of waves in printing. Due to these characteristics and light weight, it replaces cardboard packaging. Transportation alone cannot be used as packaging. When combined with another wave, it becomes an excellent packaging material.The F wave and the N wave are other types that are thinner than the E wave.
Package, Box and Other Corrugated Packaging Models According to Fefco Standards,

Fefco 0200 Open Top Box
Fefco 0201 Standart ABox
All the lids of the standard box are the same size. Their outer covers converge in the middle of the box. The distance between the inner Decals varies depending on the size - to - size ratio of the box. They become the packaging of many products. If it is desired to better protect the product on the bases, a piece suitable for the size is placed in the space left between the Decals. This method is especially used to eliminate the step difference that occurs at the bottom of the box in boxes that are produced from multiple waves and where many products are packaged.In such cases, the less economical box 204 can also be used.
Fefco 0202 Double Side Long Lid Box
The difference from the standard box is that all cover lengths are kept long in the specified dimensions and the outer covers are superimposed. This solution, which is another way to make the Decking space between the covers economical in terms of production and use, is usually used as packaging of heavy products. Otherwise, it creates a problem in the stack because the box base will not come parallel to the ground. The covers of these types are usually closed with wire stitching.
FEFCO 0203 Full Lid Box
This type, in which the box outer covers are exactly superimposed, is resistant to collapse. The boxes, which are usually the narrowest in size and stacked on the side face, are resistant to stacking due to the cardboard layer formed at the beginning.
FEFCO 0215 Switch-Based Box
This box, which is one of the molded box types, is usually considered as consumer packaging due to its lower and upper lids, which are locked when closed with a certain sequence without requiring tape. The splicing part is usually performed as gluing in the company that makes the box production.
FEFCO 0301 Telescopic Box
The boxes, which are called molded or produced as a standard pan, are shipped flat. After installation, the corners are glued or sewn by the user company. They are widely used in cut flower packaging processes in our country.
FEFCO 0320 Telescopic Box
It is formed by passing two 0200 coded boxes with a lid on one side onto each other with their mouths facing each other. Usually the inner and outer box are made of different corrugated cardboard. The presence of a double layer of cardboard thickness on the side walls makes the box durable. Especially in these types used as citrus packaging, since the collapse value of the box decreases due to external factors such as climatic conditions, waiting in the stack, shipment, the inner parcels are produced moisture-resistant using double wave, even various auxiliary materials on some faces. The outer boxes, on the other hand, are usually produced with stunning prints using white or marbled papers. In particular, the loss of surface crush value caused by pressures on large surfaces decreases in this type of box.
FEFCO 0350 - 0351 Bulk Box
They are used in the packaging of granular and powdered products. This box, which is shaped with octagonal pans passed on the bottom and top of octagonal tube-shaped side walls, can carry very large loads due to its geometric form. It is moved with the pallet, fastened to the pallet by strapping. When it comes to powdered products, a plastic bag with a large bellows is used inside.
FEFCO 0409 One-Piece Telescopic Box
This box, which is usually sealed in automatic filling machines, is multi-purpose. It packages many products from durable consumer goods to meat. It is resistant to stacking on top of each other.
FEFCO 0422 Folding Interlocking Sheet
