Abstract

An anti-fogging air conditioned preservative film adding anti-fogging materials comprises the following components: 100 portions of low-density polythene resin, 15 portions of linear polythene resin, 10 portions of ethylene-vinyl acetate resin, 0.5 portion of tween-20, 0.5 portion of span-20, 5 portions of fluoride, 4 portions of active carbon, 0.4 portion of 1076 antioxidant, 1.5 portions of SWJU-1 anlistatig and 0.5 portion of polythene wax. The preservative film is formed by mixing and blow-molding according to the feed proportioning. The manufactured film has bidirectional adjusting ability of O2 and CO2, and therefore, when used for small-package storage, the film can spontaneously adjust air and has good anti-fogging performance without condensation of moisture in the bag, and has stronger sorption function and permeability for vapor, and the like.

Description

technical field [0001] The invention belongs to agricultural product fresh-keeping film, in particular to a kind of grain fresh-keeping film filled with anti-fog materials-anti-fog modified atmosphere fresh-keeping film and its production method. Background technique [0002] Its fresh-keeping performance of general preservative film can't be perfect at present. When using plastic wrap to keep grain fresh, when encountering temperature changes, the moisture in the space inside the plastic wrap will cause fog to form on the wall of the plastic wrap. Affect the preservation effect. Contents of the invention [0003] The object of the present invention is to provide a grain preservative film added with anti-fog material-anti-fog modified atmosphere preservative film and its production method, so as to overcome the shortcomings and deficiencies of the existing general preservative film technology. Make it use fresh-keeping effect to improve. [0004] The purpose of the pres...
