What are the materials of the packaging carton

With the development of the global packaging industry and logistics industry, the requirements for the quality of the packaging cartons are getting higher and higher, especially for the long-distance transportation of the packaging boxes, the poor printing effect caused by the warping of the cardboard, the softening of moisture absorption and the products caused by the opening of the glue Damaged or scrapped, resulting in returns, claims and other cases occur from time to time. It can be seen that the quality of packaging cartons is very important to the packaging and logistics industry. So, what are the materials of the packaging carton?

There are three layers and five layers commonly used in cartons, and seven layers are used less frequently. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The color and feel are different, and the paper (color, feel) produced by different manufacturers is also different. The following is the introduction of various base paper materials for carton packaging organized by Xiaobian:

1.Tea board paper: The color of tea board paper is grayish white and rough. The tea board paper mixed with old materials has less fiber content and average quality. The tea board paper is the middle layer of the corrugated carton, which is very soft. Because the quality is not good, the price of tea board paper is also high.

2. Box board:

(1) Kraft cardboard (US card, Russian card). Features: long fiber, heavy sizing, high physical strength, rough board; pure wood pulp or a small amount of OCC. Abbreviation: Imported cattle card.

(2) Imitation kraft cardboard. Features: 15-25% wood pulp is hung on the surface, and the rest is OCC; the fiber is shorter and the strength is worse than that of kraft cardboard. The paper surface is smooth, with different degrees of sizing (water absorption ranging from 30-55g/m2), and surface dyeing treatment. Abbreviation: Domestic cattle card.

3) White cardboard. White surface ox card bottom, the surface is made of white wood pulp, and the rest is natural or dyed wood pulp. (Russian white, Swedish white card, Finnish white card); white board paper (white wood pulp on the surface, the rest are deinked or non-deinked waste paper); coated white board paper (white background, gray background, etc.) .

(4) Recycled paper. All composed of OCC, but different from corrugated paper. The surface is 11# or more AOCC noodles and has been dyed). The market is generally called C-grade containerboard, and some are called T paper.

3. Corrugated base paper: Corrugated paper is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during handling. The corrugated corrugations of corrugated paper are like connected arched doors, which are arranged in a row and support each other to form a triangular structure. Good; it can be made into pads or containers of various shapes and sizes according to needs, which is simpler and faster than plastic buffer materials; it is less affected by temperature, has good shading properties, is not deteriorated by light, and is generally less affected by humidity, but It is not suitable for long-term use in an environment with high humidity, which will affect its strength.

Because corrugated box packaging has the characteristics of strong content protection, easy identification, easy handling, easy unpacking, and exquisite printing, it has become one of the fastest growing product packaging forms in recent years. The above are the relevant answers about "packaging carton material", I hope to be of some help to you.
