What Are The Materials Of Packing Cartons?
With the development of global packaging industry and logistics industry, the requirements for the quality of packaging carton are higher and higher, especially for the long-distance transportation of packaging carton, the cases such as poor printing effect caused by the warpage of paperboard, moisture absorption and softening, product damage or scrap caused by the opening of glue, the return of goods, claim and so on occur from time to time. It can be seen that the quality of the packaging carton is very important for the packaging logistics industry. So, what are the materials for packing cartons?
What Are The Materials Of Packing Cartons?
Cartons are commonly used in three or five layers, while seven layers are seldom used. Each layer is divided into inner paper, corrugated paper, core paper and face paper. The inner paper and face papers are tea board paper and kraft paper, and the core paper is corrugated paper. The color and handle of all kinds of paper are different, and the paper (color and handle) produced by different manufacturers are also different. The following is a brief introduction of various base paper materials used for carton packaging of small knitting and finishing:
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 composition and average quality. Tea board paper is the middle layer of corrugated paper in the carton, which is very soft. Because of the poor quality, the price of tea board paper is the cheapest.
- Kraft card (American card, Russian card). Features: long fiber, heavy sizing, high physical strength, rough paperboard; pure wood pulp or a small amount of OCC. Abbreviation: imported cattle card.
- Imitation kraft cardboard. Features: 15-25% wood pulp is hung on the surface, the rest is OCC; the fiber is shorter and the strength is worse than that of kraft liner board. The paper surface is smooth, sizing with different degrees (water absorption 30-55g / m2) and surface dyeing. Abbreviation: domestic Nika.
- White cardboard. White kraft, surface bleached wood pulp, the rest of the natural color or dyed wood pulp. (Russian white, Swedish white card, Finnish white card); whiteboard (surface bleached wood pulp, the rest is deinked or non deinked waste paper); Coated Whiteboard (white background, gray background, etc.).
- Recycled paper. All of them are composed of OCC, but different from corrugated paper. The surface is AOCC vermicelli (above 11 and dyed). The market is generally called C-grade cardboard, and some are called t-paper.
3. Corrugating Base Paper
corrugating paper is a multilayer adhesive, which is composed of at least one layer of corrugated core paper interlayer and one layer of paperboard. It has high mechanical strength and can withstand collision and fall during transportation. Corrugating corrugations of corrugated paper are like connected arched doors, which are arranged side by side and support each other to form a triangular structure. They have good mechanical strength, can bear certain pressure from the plane, and are full of elasticity, with good buffering effect. They can be made into liners or containers of various shapes and sizes according to needs, which is simpler and faster than plastic buffering materials. They are affected by temperature Small noise, good shading, light does not deteriorate, generally less affected by humidity, but it is not suitable for long-term use in the environment with high humidity, which will affect its strength.
Due to its strong protection function, easy to identify, ease to handle, easy to open the box and exquisite printing, corrugated box packaging has become one of the fastest-growing product packaging forms in recent years.
