Description

Degradable composite paper ink layer structure and packaging paper box

Technical Field

The present disclosure relates to the technical field of packaging cartons, and in particular to a degradable composite paper ink layer structure and a packaging carton.

Background Art

Packaging box, as the name implies, is a box used to package products. It can be classified by material, such as paper box, iron box, wooden box, cloth box, leather box, acrylic box, corrugated packaging box, PVC box, etc. Among them, packaging box is the most widely used.

In the related art, a waterproof film is attached to the surface of the base paper fiber, and a marking ink layer is sprayed on the waterproof film. The traditional waterproof film is a non-degradable plastic film. However, in order to protect the environment, degradable films are currently used to replace plastic films, such as a degradable polyester synthetic paper disclosed in CN213866035U.

However, the ink has poor binding properties with the degradable film, that is, the ink has poor adhesion to the degradable film, which causes the marking ink layer to fall off accidentally more easily during the movement of the paper box.
