Abstract

The invention discloses a polyethylene aluminum-plated film with metal luster of an aluminum foil diffuse surface. An aluminum-plated functional layer comprises 50 to 80 parts of polyethylene and 20 to 50 parts of ethylene acrylic acid copolymer or ethylene methyl acrylate copolymer or ethylene vinyl acetate copolymer. The ethylene acrylic acid copolymer or ethylene methyl acrylate copolymer or ethylene vinyl acetate copolymer is added into the polyethylene, the polarity of the material and the binding force of the material with an aluminum material are improved, and after the film is processed through a film blowing or casting process, the surface haze is improved; meanwhile, the aluminum foil diffuse surface is formed, and the polyethylene aluminum-plated film with metal luster of the aluminum foil diffuse surface is formed through vacuum aluminum plating. The appearance of the product has the metal luster of the aluminum foil diffuse surface, and the product has ideal processability, excellent aluminum adhesive force, excellent gas barrier property, excellent moisture barrier property, good heat sealing performance and low-temperature mechanical property, and is suitable for mass production and low in industrial production cost.

Description

technical field [0001] The invention relates to a polyethylene thin aluminized film, in particular to a polyethylene thin aluminized film with a metallic luster on the diffuse reflection surface of an aluminum foil obtained by ring film blow molding or casting processing. Background technique [0002] The aluminized film mainly has excellent gas barrier performance, moisture barrier performance, and light reflection performance. The current aluminized materials are also newly endowed with decorative and anti-counterfeiting functions. [0003] The materials that can be processed by aluminizing mainly include unstretched polypropylene, biaxially oriented polypropylene, and biaxially oriented polyethylene terephthalate. After the surface is aluminized, the aluminized surface is mirror reflection. [0004] Aluminum-plated materials with heat-sealing properties include unstretched polypropylene, aluminum-plated unstretched polypropylene, aluminum-plated peeling off after compoun...
