Description

Precoated film packing box

Technical Field

The invention relates to the technical field of packaging boxes, in particular to a pre-coated film packaging box.

Background

The packaging is a protection and decoration mode for the articles, the articles are wrapped with a layer of material on the outer side and then transported, the articles can be fully protected, and the purpose of beautifying the appearance can be achieved through external printed information and decoration of accessories.

Most of the packing boxes on the market are composed of box bodies and box covers, the box covers are adhered to the box bodies into a whole through outer packing paper at a folding position when the packing boxes are used, other decorations are used for increasing the attractiveness of the packing boxes, connecting pieces and decorations need to be pasted on the outer surfaces of the packing boxes, so that the packing boxes are easy to damage packaged objects and the sales of the objects are greatly influenced. The integrally formed folding packaging box also exists in the market, and after the paper which is cut is folded, buckled and adhered for multiple times, the packaging box capable of containing articles is formed. Because the periphery of the box body is formed by folding paper, only one layer of paper board is usually arranged, and the strength is lower.

The outer packaging box for food needs to have certain strength and simultaneously has the functions of moisture prevention and mold prevention, so that the surface of the packaging box needs to be subjected to waterproof treatment, and the service life of the packaging box is prolonged.
