Abstract

Disclosed are special-purpose films and bags for the fresh-keeping of jujubes, wherein the constituents of the raw materials include (by weight portions) linear polyvinyl resin (LLDPE) 100, high-tension polyvinyl resin (LDPE) 50-100, ethylene-vinyl acetate resin (EVA) 15-25, 10% antifog pellets (MD / PE) 5-10, 20% silver-containing antibiotic pellets (Ag / PE) 5-10, 20% calcium carbonate pellets (CaCO3 / PE) 5-15 and 2-ethylhexyl oleate 0.2-1.

Description

technical field [0001] The invention belongs to fresh-keeping articles for agricultural products, in particular to a special fresh-keeping film and bag for Jinling jujube. Background technique [0002] At present, there are many supplies in the fresh-keeping technology of agricultural products, such as fresh-keeping agents and fresh-keeping films. All fresh-keeping products such as preservatives and plastic wrap are selectively used for the objects to be kept fresh. Different varieties of agricultural products need to use different fresh-keeping products. Also do not have the special-purpose fresh-keeping film and the fresh-keeping bag for Jinling jujube fresh-keeping at present. Contents of the invention [0003] The purpose of the present invention is to provide a special film and bag for fresh-keeping of Jinling jujube, which is suitable for storage and fresh-keeping of Jinling jujube. [0004] The technical scheme of the present invention is: produce jujube preserva...
