Film-covering type plastic paperboard

Abstract

The invention discloses a film-covering type plastic paperboard. The film-covering type plastic paperboard at least composed of following five layers of boards, namely, two layers of plastic films, two layers of leatheroid and a layer of wave-shaped PP plastic board in a composited mode, wherein the wave-shaped PP plastic board is arranged in the middle layer, the two layers of leatheroid are arranged on the upper face and the lower face of the wave-shaped PP plastic board correspondingly, and the two layers of plastic films are arranged on the outer surfaces of the two layers of leatheroid correspondingly. The edges of the wave crests and the wave troughs of the wave-shaped PP plastic board are coated with glue, and the wave-shaped PP plastic board and the leatheroid arranged on the upperface and the lower face of the wave-shaped PP plastic board are connected through the glue. In the mode of backing adhesive or in the mode that the surface of the leatheroid is coated with the glue,the plastic films and the whole surfaces of the leatheroid are pasted. The edge of the board formed by the two layers of plastic films, two layers of leatheroid and the layer of wave-shaped PP plasticboard in a composited mode is subjected to glue filling for sealing or provided with an edge sealing strip for sealing through bonding, and the sealing and waterproof effects are achieved.

Description

technical field [0001] The invention relates to the technical field of cardboard, in particular to a film-coated plastic cardboard, which is mainly used as a packaging carton for logistics and freight. Background technique [0002] Packaging boxes are mainly used for transportation, loading, unloading and storage. In recent years, with the rapid development of online shopping and logistics, the demand for packaging boxes is huge. Most of the existing packaging boxes use corrugated cardboard cartons. Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by processing corrugated sticks. It is generally divided into two types: single corrugated cardboard and double corrugated cardboard. Traditional corrugated cardboard and cardboard are combined to make packaging cartons. On the one hand, the cardboard itself is not strong enough to be waterproof, and the surface is prone to dust and ink stains, making it difficult to clean. On the other hand, ...

AI Technical Summary

Problems solved by technology

The traditional corrugated paper and cardboard composite cardboard is made of packaging cartons. On the one hand, the cardboard itself is not strong enough to be waterproof, and the surface is prone to dust and ink stains, which is difficult to clean.

On the other hand, cartons made of traditional corrugated paper are easy to be damaged, deformed, softened by moisture, etc. after one or two uses, and cannot be recycled, which is likely to cause waste of resources
