A film-coated outer packaging box and its manufacturing method

Abstract

The invention discloses an outer packaging box covered with an outer film, comprising a box body, the box body sequentially includes an anti-corrosion layer, a deodorizing layer, a plastic plate and an adhesive from the inside to the outside, and a cross groove is opened inside the plastic plate , the inside of the anti-corrosion layer is provided with a through hole, the deodorizing layer is formed by blending weaving of the adsorbent and the foam layer, and the raw materials of the adhesive include 10-15 parts of polyurethane, polystyrene 23-27 parts of ethylene, 12-18 parts of ethylene-acetic acid, and 20-25 parts of ethylene copolymer relate to the technical field of packaging boxes. The outer film-coated packaging box and its manufacturing method can make the surface of the plastic board have protection functions such as moisture-proof, waterproof, anti-fouling, wear-resistant, folding-resistant, and chemical-corrosion-resistant by using the adhesive, and can protect the packaging box. The product is fully protected, and the toughness of the packaging box can be enhanced by using the cooperation between the cross groove and the olefinic soft plastic layer, so as to prevent the packaging box from being deformed after being collided, which will affect the product in the packaging box, and further protect the product.
