Abstract

The invention discloses a freshness-keeping package material capable of strongly replacing gas. The package material is prepared from the following components in parts by weight: 100 parts of low-density polyethylene resin, 35-45 parts of linear polyethylene resin, 16-18 parts of ethylene-vinyl acetate resin, 13-15 parts of -220 mesh diatomite, 11-13 parts of -100 to +200 mesh kaolin, 2-4 parts of -300 imvite, 3-5 parts of vinylsilane A171, 1.8-2.2 parts of glycerol monostearate and 3.5-5.5 parts of polyethylene wax.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a fresh-keeping packaging material with strong displacement gas. Background technique [0002] After fruits and vegetables are picked, they are still a biological organism during storage, constantly undergoing metabolism and physiological decay, so the preservation of fruits and vegetables is very important. [0003] At present, there are many storage methods. Putting fruits and vegetables into polyethylene film packaging bags and sealing them in a controlled atmosphere storage is the most commonly used method. Due to the poor air permeability of the polyethylene film, the seal of each bag should be opened and vented regularly during the storage period, which increases the labor intensity and makes it difficult to ensure the storage quality. In order to solve this problem, a silicon window preservative film has appeared. Its structure is to open a certain area of ​​h...
