Abstract

The invention provides a functional packaging film and a production process thereof. The functional packaging film comprises the following raw materials in parts by weight: 80-100 parts of polyethylene resin, 4-16 parts of carboxymethyl chitosan, 0.4-0.8 part of diacetyl tartaric acid ester of mono(di)glycerides, 3-6 parts of silica, 0.3-0.8 part of sodium starch octenyl succinate, 0.025-0.055 part of antioxidant, and 0.1-0.3 part of benzoic acid. The production process of the functional packaging film comprises the following steps: S1, weighing raw materials; S2, preheating and drying polyethylene resin; S3, preparing a functional composition by carboxymethyl chitosan and diacetyl tartaric acid ester of mono(di)glycerides; and S4, mixing the materials, and conducting granulation, drying and film blowing, so as to obtain the functional packaging film. The packaging film provided by the invention has excellent bacteriostasis and gas permeability, prolongs the preservation time of packaged objects, and has a simple production process.

Description

technical field [0001] The invention relates to the technical field of packaging films, in particular to a functional packaging film and a production process thereof. Background technique [0002] Film is a thin and soft transparent sheet, usually made of plastic, adhesive, rubber or other materials, such as optical film, composite film, superconducting film, polyester film, nylon film, plastic film, film in electronic appliances, Widely used in machinery, printing, food and other fields. In particular, the packaging film used in the food field can ensure that food is free from contamination by external pollutants, is convenient for transportation and carrying, and can also ensure the freshness of food. [0003] However, since the packaging film is in direct contact with food, its packaging is directly imported food, so the most basic requirement of the packaging film in the food field is to meet the requirements of food hygiene. It is precisely because the packaging film ...
