Abstract

The invention discloses a freshness protection bag special for fruit refrigeration, and belongs to the field of packaging bags. The bag is prepared from, by weight, 35-41 parts of polyethylene, 5-7 parts of light calcium carbonate, 3-5 parts of epoxidized soybean oil, 2-4 parts of Arabic gum, 21-25 parts of polypropylene, 15-17 parts of bamboo charcoal fiber, 19-23 parts of chitosan, 10-12 parts of sodium polyacrylate, 5-9 parts of zeolite powder and 2-4 parts of chloro-methoxy fat diethylene glycol dinitrate. The freshness protection bag special for fruit refrigeration can restrain bacteriumbreeding and prolong fruit refreshing time.

Description

technical field [0001] The invention relates to the field of packaging bags, in particular to a fresh-keeping bag specially used for fruit refrigeration. Background technique [0002] Fresh-keeping bags mainly refer to bags made of food plastic wrap, which are mainly used to preserve vegetables, fruits, grains, cooked food and other foods, and are widely used in daily life. Fresh-keeping bags are divided into polyethylene (PE), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) and other types according to the production material. Fresh-keeping bags are mostly used to package food, such as fruits and vegetables. Generally, people are used to putting the fruit in the fresh-keeping bag and then putting it in the refrigerator, but after the current fresh-keeping bag is left for a long time, the moisture in the fruit will be released, and the water will become water droplets attached to the inner wall of the fresh-keeping bag when it is cold , It is easy to breed bacteri...
