Abstract

The invention discloses a novel antifogging hybridization composite membrane for food packaging. The antifogging hybridization composite membrane comprises, by weight, 100-110 parts of base material,1.2-1.5 parts of modified antifogging agent, 2.0-2.5 parts of base-material graft and 0.3-0.5 part of nano inorganic filler, wherein the base material is the mixture formed by high-density polyethylene and methyl methacrylate-butadiene-styrene copolymer; the modified antifogging agent is obtained by subjecting polyethylene glycol-polyglutamic acid-polyalanine triblock copolymer to protoporphyrin IX Mn(III) chloride and sodium lauryl sulfonate modification; the base-material graft is graft copolymer obtained by grafting methacrylic acid to the main chain of the methyl methacrylate-butadiene-styrene copolymer under the effect of an initiator. The prepared novel antifogging hybridization composite membrane is excellent in antifogging effect and excellent in mechanical performance.

Description

technical field [0001] The invention belongs to the technical field of food packaging, and in particular relates to an anti-fog hybrid composite film for food packaging and a preparation method thereof. Background technique [0002] Vegetables, fruits, meat and frozen food, because of their high moisture content or the large temperature difference between the inside and outside of the packaging bag, usually produce a layer of opaque water mist in the packaging bag, and this layer of opaque water mist will prevent the user from seeing It is impossible to visually judge the quality of the product. In order to solve this problem, the outer packaging of the product is usually packaged with an anti-fog film that prevents water vapor from forming fog on the surface of the film. [0003] The anti-fog film can change the surface properties of the material, and its anti-fog principle can be roughly divided into two categories: the first type is a hydrophilic anti-fog film, which red...
