With the development of the global packaging industry and logistics industry, the requirements for the quality of packaging cartons are getting higher and higher, especially for the packaging cartons that are transported over long distances. The printing effect caused by the uneven cardboard warping, the moisture absorption and the softening and the opening of the glue cause the product Damaged or scrapped goods, 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 logistics industry. So, what are the materials of the packaging cartons?
There are three layers and five layers commonly used in cartons. Seven layers are used less frequently. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are teaboard paper, kraft paper, corrugated paper for core paper, and various types of paper. The color and feel are different, and the paper (color, feel) produced by different manufacturers is also different. The following is an introduction to the various base paper materials of the carton packaging organized by the editor:
1. Tea board paper: The tea board paper is grayish and rough in color. The tea board paper mixed with old materials has less fiber content and is of average quality. Cardboard is the paper in the middle of the corrugated carton, which is very soft. Because of the poor quality, the price of tea board paper is also the cheapest.
2. Cardboard paper : (1) Kraft cardboard (American card, Russian card). Features: long fiber, re-sizing, high physical strength, rough cardboard; 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 cow cardboard. The paper surface is smooth, sizing in different degrees (water absorption ranging from 30-55g/m2), and surface dyeing treatment. Abbreviation: domestic cattle card.
3) White cardboard. White flour cattle card base, surface bleached wood pulp, the rest is natural or dyed wood pulp. (Russian white, Swedish white card, Finnish white card); white paper (surface bleached wood pulp, the rest is deinked or non-deinked waste paper); coated white paper (white on white, white on gray, etc.).
(4) Recycled paper. All are composed of OCC, but different from corrugated paper. The surface is AOCC dried noodles above 11# and dyed). The market is generally called C-level boxboard paper, and some are called T paper.
3. Corrugated base paper: Corrugated paper is a multi-layer glued body, which is at least composed of a layer of wavy core paper interlayer and a layer of cardboard. It has high mechanical strength and can withstand collisions and falls during handling. The corrugated corrugation of corrugated paper is like a connected arched door, arranged in a row and supporting each other to form a triangular structure. It has good mechanical strength, can withstand a certain pressure from the plane, and is elastic and has a buffering effect. Good; it can be made into pads or containers of various shapes and sizes according to needs, which is simpler and faster than plastic cushioning materials; it is less affected by temperature, has good shading, and 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 the corrugated carton packaging has the advantages of strong protection of the contents, easy identification, easy handling, easy opening of the box, and exquisite printing, it has become one of the product packaging forms with the fastest growth in demand in recent years. The above is the relevant answer about the "packaging carton material", I hope it will be of some help to you. The editor here recommends Wulian Yuncang Mall for everyone.
