Drug-containing fresh packaging paper

Immersion fresh paper. Food is susceptible to bio-erosion in circulation and must be packaged. If the packaging paper is treated with a volatile bactericide, the food can be continuously subjected to drugs in the packaging to achieve the purpose of preservation. For example, the package box for impregnating citrus with mixed volatile biphenyl, paraffin and mineral oil can prevent fruit rot during storage and transportation. A Japanese company manufactures an anti-corrosion food wrapper, which is prepared by immersing the base paper in an ethanol solution containing 20% ​​succinic acid, 33% sodium succinate, and 0.7% sorbic acid. Dry it. Foods with marinade packed in such paper can be stored at a high temperature of 30°C for 3 weeks without deterioration.
