Made in USA with tiny air holes

A U.S. company used a new type of polymer as a material to make a plastic film with tiny air holes. Packaging fruits and vegetables with this film can control the exchange of oxygen and carbon dioxide in the packaging bag, so that the packaging can maintain an optimal atmosphere for slow fruit and vegetable respiration, thus effectively extending the shelf life. Under normal conditions, its freshness can be increased by 1 time. (Li Lingling) ("China Packaging News")
