Description

Corrugated paper box

Technical Field

The utility model relates to a fixed field of box, more specifically say, relate to a corrugated box.

Background

Corrugated board is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly called as "hole paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of paper board (also called as "box board paper" or "box paper board"). It has high mechanical strength and can resist collision and falling in the process of transportation. The actual performance of a corrugated box depends on three factors: the characteristics of the core paper and paperboard, and the structure of the carton itself, are also known as corrugated paperboard. Is formed by bonding at least one layer of corrugated paper and one layer of boxboard (also called boxboard), and has better elasticity and extensibility. The method is mainly used for manufacturing cartons, the sandwich of the cartons and other packaging materials of fragile commodities. The raw paper board similar to yellow paper board is made up by using straw pulp of earth method and waste paper through pulping, then is mechanically processed and rolled into corrugated form, then on its surface the adhesive of sodium silicate is used to adhere it to the cardboard paper so as to obtain the invented product.

The corrugated corrugations of the corrugated board are like arch doors which are connected one by one, are mutually parallel to form a row and mutually support to form a triangular structure body, so that the corrugated board has better mechanical strength, can bear certain pressure from a plane, is rich in elasticity and has good buffering effect; the cushion can be made into liners or containers with various shapes and sizes according to requirements, and is simpler, more convenient and faster than plastic buffer materials; the coating is slightly influenced by temperature, has good light-shielding property, is not deteriorated by illumination, is generally slightly influenced by humidity, but is not suitable for long-term use in an environment with high humidity, and influences the strength of the coating.

Traditional flute case forms for corrugated container board direct processing, and traditional flute case seals fixedly through using scotch tape to the case lid, and sealed fixed effect is poor, and scotch tape damages the case lid seriously when opening the case lid, can't improve the reuse rate of flute case.
