Abstract

The invention discloses a lightweight fresh-keeping and anticorrosive composite packaging material for vegetables and fruits. The lightweight fresh-keeping and anticorrosive composite packaging material is prepared from the following raw materials in parts by weight: 50-100 parts of matrix resin, 3-8 parts of neopentyl glycol diglycidyl ether, 5-10 parts of hydroxy propyl distarch phosphate, 2-6 parts of polyvinyl pyrrolidone, 1-5 parts of sodium polyacrylate, 1-3 parts of calcium carbonate, 1-3 parts of resorcinol bis(diphenyl phosphate), 5-10 parts of hydroxy propyl distarch phosphate, 1-3 parts of hydroxyl silicone oil, 0-58 parts of modified filler, 0.5-2 parts of a light stabilizer, 0.5-1.5 parts of an antioxidant and 0.2-0.8 part of fungicide, wherein the matrix resin is resin of ethylene-1-octylene copolymer, polyvinyl butyral and molybdenum-modifying phenol-formaldehyde, and the ratio in parts by weight is (2-4):(1-2):1. The lightweight fresh-keeping and anticorrosive composite packaging material for vegetables and fruits is a vegetable and fruit packaging product raw material which has the characteristics of being light in weight, fresh-keeping, anticorrosive, free of pollution, free of peculiar smell, free of toxic chemical substance and smooth in surface.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a light-weight, fresh-keeping and anti-corrosion composite packaging material for fruits and vegetables. Background technique [0002] Fresh fruits and vegetables are fresh commodities with high water content. After harvesting, they still continue to carry out life activities such as respiration and transpiration. Without proper packaging conditions, they are easy to lose water and shrink or rot and deteriorate during circulation. Fresh-keeping technology can not only reduce product loss, but also greatly increase the added value of agricultural and sideline products. The added value of agricultural and sideline products in developed countries has reached more than 70%. Packaging materials and other fresh-keeping technologies are very important means to improve the economic benefits of agricultural and sideline products. Fruit and vegetable packaging materials should have suff...
