We are Xinqicai Printing Co., Ltd., providing customized services for
corrugated paper boxes. So what are the differences in the composition of different corrugated cardboard? Here are some explanations for
Custom Corrugated Boxes.
K838k cardboard, k535k cardboard, k636k cardboard, and k535a cardboard are actually 5-layer corrugated cardboard. k/a represents the face paper or base paper, and the weight of the face paper and base paper varies depending on the manufacturer. Except for some special materials, K paper is one of the best among major suppliers. 5, 6, 8, etc. represent the pit paper number, 3 is the core paper, usually using k-paper as the face paper, 6 is the name of the pit paper formed by reinforcing the core paper with ridges, the hardness of the 6-paper reinforced core material is much better than that of K=K material, and so on, there are also 7-paper reinforced cores; The 8-paper reinforced core has better wear resistance and compressive strength than ordinary paper.
K535k cardboard
For example:
The material characteristics of K535K are as follows:
Thickness: 6.1mm-6.5mm;
Durability: 13.0kgf/cm2 to 15.0kgf/cm2;
Edge compression strength: 7.50kgf/cm-8.50kgf/cm.
The material properties of K=K are as follows:
Thickness: 6.1mm-6.5mm;
Durability: 12.5kgf/cm2 to 14.0kgf/cm2;
Edge compression strength: 5.50kgf/cm-6.00kgf/cm.
K636K cardboard structure: K-paper is used as the surface paper, 6-paper is the pit paper, 3-paper is the core paper, 6-paper is the pit paper, K-paper is the base paper, and a five layer corrugated cardboard is synthesized by adhesive The same applies to K535K and K838K.
Cardboard is made of corrugated paper glued together by a pit paper machine, usually with specifications such as single pit (three layers), double pit (five layers), and three pit (seven layers).
Single pit cardboard, composed of face paper, pit paper, and base paper
Double pit cardboard, composed of face paper, pit paper, core paper, pit paper, and base paper

K838K cardboard
Common expressions for single pit 3 ± 1MM: K3K, K3A, A3A, etc
Double pit 6 ± 1MM commonly used expression: K=K,K=A,A=B
Three pit 9 ± 1MM commonly used expression: K, three K, K # K can all be used
Face paper and base paper mainly include paper materials such as k, a, b, c, and 3 W (white), with k paper thickness → 3 paper thin
Type and thickness of pit paper:
A ridge 4MM B ridge 3MM C ridge 3.5MM E ridge 1.8MM
E-Leng, also known as E-KengYoukeng, has a three-layer thickness of 1.5-2.0mm. It is currently a very thin cardboard on the market that is usually matched with a tearing design for brand e-commerce product corrugated paper boxes.
