How to develop e-commerce express? The packaging industry and logistics industry are in great demand, and the requirements for the quality of packaging cartons are getting higher and higher, especially for packaging boxes that are transported over long distances. The product is damaged or scrapped due to the opening of the glue, and cases such as returns and claims caused by it 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?

Suzhou carton manufacturers commonly use three layers and five layers, and seven layers are used less often. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The color and feel of the paper 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 by Suzhou dangerous goods carton manufacturers:

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 very cheap.

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-faced cow card bottom, bleached wood pulp on the surface, and the rest are natural or dyed wood pulp. (Russian white, Swedish white card, Finnish white card); white board paper (surface bleached wood pulp, 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 consists 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, does not deteriorate 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.
