Problems solved by technology

Therefore, the rapid development of vacuum aluminum-coated paper in the Asia-Pacific region is the general trend, and the prospect is optimistic. Traditional vacuum metal-coated paper has good flexibility in the field of food and pharmaceutical packaging, but the amount of aluminum used is very low, usually the aluminum layer is only 0.025 um~0.035um, although the cost of use is low, but as a packaging material, its printing performance is limited, the strength of the paper is reduced, and the carat performance of the traditional vacuum aluminized paper is not good

Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0014] A vacuum aluminized paper, comprising a base layer 3 and an aluminum coating layer 1, the thickness of the aluminized layer 1 is 0.05um to 0.075um, a tensile layer 2 is also provided between the base layer 3 and the aluminized layer 1, the Tensile layer 2 is a composite material of epoxy resin and polyphenylene ether, which moderately increases the traditional aluminum-coated layer, improves the strength of the paper, is simple to make, and has better printing effect. It is easy to handle and recycle, and is an environmentally friendly product. The tensile layer enhances the tensile properties of the aluminized paper. Both epoxy resin and polyphenylene ether have good tensile strength, and the connection process with the paper base is easy t...

Abstract

The invention discloses a vacuum aluminized paper and relates to the package material field. The vacuum aluminized paper comprises a base layer and an aluminized layer. The vacuum aluminized paper is characterized in that the thickness of the aluminized layer is 0.05-0.075 micron; a pull-resisting layer is arranged between the base layer and the aluminized layer; the pull-resisting layer is made of composite materials of epoxy resins and phenyl ether. The vacuum aluminized paper can be applied in the food and medicine packaging fields, and has good flexibility and pull resistance. The intensity of the paper can be ensured and damage can be prevented. The vacuum aluminized paper is an environmental protection material with air blocking performances of aluminum foil composite papers.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a vacuum aluminized paper applied to food and medicine packaging materials. Background technique [0002] Vacuum metallized paper is a new type of green packaging material widely used in the packaging industry in the world since the 1980s. At present, the largest application markets for vacuum metallized paper are North America and Europe. In the past ten years, the growth of vacuum metallized paper in the North American and European markets rate of more than 6%. Therefore, the rapid development of vacuum aluminum-coated paper in the Asia-Pacific region is the general trend, and the prospect is optimistic. Traditional vacuum metal-coated paper has good flexibility in the field of food and pharmaceutical packaging, but the amount of aluminum used is very low, usually the aluminum layer is only 0.025 um ~ 0.035um, although the use cost is low, but as a packaging material, it...
