Description

Black aluminum plastic film

Technical Field

The utility model relates to the technical field of aluminum-plastic packaging, in particular to a black aluminum-plastic film.

Background

The existing surface black aluminum-plastic packaging composite film adopts two processes, one is that black ink and a dispersing agent are added into surface first bonding layer glue to blacken the bonding layer, and then matte oil is coated on the protective surface outside a nylon layer, so that the surface of the aluminum-plastic film after being compounded is matte black; the other process is to print on the composite surface of the nylon layer, coat printing ink mixed by black ink and dispersant, and then coat matte oil on the outer protective surface of the nylon layer, so that the surface of the compounded aluminum-plastic film is matte black. However, after macromolecular ink is coated on the surface of the glue layer or the nylon membrane, the adhesive property between the nylon layer and the aluminum foil is reduced, so that the peeling strength of the product is reduced, and the high-temperature and high-humidity resistance is reduced, thereby affecting the safety performance of the product.
