Have you ever met these problems, the products you ordered from the factories months ago, and they finally arrived your there during long sea transportation, but the cartons are all deformed?
The products inside are also deformed, which is no benefit to sales in the market.
You bargain with the manufacturer for the price of the products that you want to purchase, however, it seems that you should pay more attention to the quality of the master cartons.
Let's learn about the knowledge of cartons together.
Cardboard boxes, also known as corrugated boxes, are made of cardboard.
Cardboard is made of layers of corrugated paper glued by machine, usually with three layers (single pit), five layers (double pits), seven layers (three pits), and so on.
Cardboard is divided into face paper, core paper, and lining paper.
The surface paper and lining paper include tea board paper, kraft paper, etc., which are divided into K, A, B, C, 3 and other grades.
For example, A=B, A is the surface paper, and B is the inner paper.
Pit paper (corrugated paper) for core paper.
According to the flute height and flute number, it is divided into A, B, C, E, N, etc.
There are differences in flute height and flute number.
Usually, it only indicates the number of pits or layers, not the pit type. "-" or "3" means single pit, "=" means double pit, "three" means three pits, and the color and feel of various papers are different.
The paper (color, feel) produced by different manufacturers is also different.
The national standard for corrugated boxes is GB6543-86 "corrugated boxes".
Classification of paper
The raw material of the carton is cardboard, and the raw material of the cardboard is the base paper.
The base paper is divided into five types of paper: K, A, B, C, and 3 paper.
The best is K paper, the worst is 3 papers.
The same is K paper is also the thickest, 3 paper is the thinnest.
K, A, B, C paper can be used as face paper and lining paper,
3 paper is mostly used as pit paper or lining paper, the material of the face paper is usually better than or equal to the lining paper, such as the face paper is A paper, the usual combination It is A=A, A=B, A=C, etc., but not A=K.
There is another kind of paper called W paper, also called white paper
As a leading supplier of kitchenware products for more than 10 years, we generally use A-B 3-layer corrugated paper for the inner box, and A=B 5 layaers corrugated paper for the master cartons when export
3-layer corrugated paper: A-B
5 layers corrugated paper: A=B
The total gross weight of the outer box of the product is less than 20KGS, which is conducive to protecting the product in the best condition.
If you have special requirements, you can contact the factory to do a box drop test when fully packing the products in the cartons.
You can also list your requirements according to the products that you are purchasing, hope you can receive your goods smoothly and in good condition.
