Recently, an active plastic packaging film was successfully developed. With this new type of packaging film, the freshness of the product can be extended by more than five times. This is undoubtedly a good news for perishable products that require long-distance transportation. This good-keeping film is a breathable film that allows the passage of quantitative carbon dioxide and oxygen, keeping the perishable product asleep. The use of such films for packaging of perishable products such as fresh fruits, vegetables, flowers, etc. can maintain their freshness for several weeks, thus better solving the problem of long-distance transportation of these products.
