FRUIT AND VEGETABLE PRESERVATION FILM AND PREPARATION METHOD THEREOF

摘要

A preparation method of a fruit and vegetable preservation film is used for preparing a three-layer co-extrusion film having a thickness ranging from 0.02 mm to 2.0 mm. A preservation master-batch composed of 5-20% of an inorganic nano-powder and 80-95% of a resin material is uniformly distributed in one layer of the co-extrusion film.
