Problems solved by technology

At present, aluminum-coated polyethylene blown film is mainly produced by medium-density polyethylene resin. The film has high haze, rough surface crystallization, and poor gloss after aluminizing. After the film is aluminized, the surface tension value of the corona layer decays quickly. , the polarity of the film surface is poor, the composite peeling force is low, and the glue is completely transferred

Abstract

The invention relates to a composite-grade high-gloss aluminized polyethylene blown film and a production method thereof. The aluminized polyethylene blown film comprises an aluminum atom accumulationlayer, a corona layer, a middle layer and a heat sealing layer; the corona layer comprises ethylene and methyl methacrylate random copolymer resin, C2-C8 metallocene catalytic copolymer plastic resinand medium-density linear polyethylene resin; the middle layer comprises low-density high-pressure polyethylene resin and medium-density linear polyethylene resin; the heat sealing layer comprises low-density high-pressure polyethylene resin, C2-C8 metallocene catalytic copolymer plastic resin, medium-density linear polyethylene resin and an opening agent master batch; the thickness of the coronalayer is 13-17 micron, the thickness of the middle layer is 18-22 micron, the thickness of the heat sealing layer is 13-17 micron, and the thickness of the aluminum atom accumulation layer is 330-380angstroms. The aluminized polyethylene blown film has high glossiness, the surface tension value can be kept at 35 dyne or above for a long time, and the composite peel strength is greatly improved.

Description

technical field [0001] The invention belongs to the field of film materials, and in particular relates to a composite high-gloss aluminized polyethylene blown film and a production method thereof. Background technique [0002] There are many applications of aluminized film in plastic composite packaging. The barrier property of the film is significantly improved after aluminized, and it can be protected from light. General substrate films, such as PET and CPP, have a high-gloss metallic appearance after aluminum plating, but polyethylene blown films generally have almost no metallic luster after aluminum plating, and the film surface is whitish, and after two weeks of storage, the aluminum-plated surface The tension value will decline to below 34 dynes, and after compounding with PET, BOPP and other films, the peeling force is less than 0.5N / 15mm. At present, aluminum-coated polyethylene blown film is mainly produced by medium-density polyethylene resin. The film has high h...
