Corrugated board is a multilayer adhesive body, it is composed of at least a layer of corrugated core paper sandwich (commonly known as "pit zhang" or "corrugated core paper") and a layer of cardboard (commonly known as "cow pickup truck"). It has high mechanical strength and can withstand bumping and falling during handling. The actual performance of corrugated carton depends on the characteristics of the core paper and cardboard and the structure of the carton itself. Corrugated carton is made of corrugated cardboard, is the most widely used paper container packaging, widely used in transportation packaging. Corrugated carton is widely used, because it has many unique advantages: (1) good buffering performance. Corrugated cardboard has a special structure, 60~70% of the volume of the cardboard structure is empty, so it has good shock absorption performance, can avoid the packaged goods by the impact and impact. ② Light and firm. Corrugated board is hollow structure, with the least amount of material to constitute a large rigid box, so light, firm, compared with the same volume of wooden cases, only for the weight of the wooden case 1/4~1/5. (3) Small size. Corrugated cartons can be folded into flat plates for convenient storage and transportation. When in use, open into the box, and than the same volume of wooden boxes, plywood box volume is much smaller. (4) Sufficient raw materials and low cost. The production of corrugated cardboard raw materials are many, corner wood, bamboo, wheat straw, reed, etc., so its cost is low, only about half of the same volume of wooden cases. ⑤ Convenient for automatic production. Now we have produced a complete set of corrugated carton production automatic line, which can produce corrugated cartons in large quantities and with high efficiency. ⑥ Low cost of packing activities. It is easy to realize the automatic packing of articles with corrugated carton, which reduces the packing workload and reduces the packing cost. ⑦ Can package a variety of articles. Corrugated carton itself packaging goods range is large, but if combined with a variety of coverings and moisture-proof materials manufacturing, more can greatly expand the scope of use, such as moisture-proof corrugated carton packaging fruits and vegetables; Packaged and moisture absorbent articles covered with plastic film; The use of plastic film bushing, sealed packaging can be formed in the box, to packaging liquid, semi-fluid items, etc. ⑧ Less metal consumption. Corrugated box molding, only a small number of nails, compared with wooden box manufacturing, and only 5% of it. ⑨ Good printing performance. Corrugated board has good ink absorption ability, easy to print, easy to promote goods. ⑩ Can be recycled. Corrugated cartons can be reused for many times, reducing the packaging cost, and no pollution to the environment.
