Abstract

This present invention discloses a polymer/potassium permanganate composite film obtainable by a process comprising the steps of using silane coupling agent for surface treatment of potassium permanganate, mixing 0.15-0.75 g of modified potassium permanganate with 10-20 g of polymers together to obtain a mixture, and coating the mixture to obtain a composite film. The composite film can absorb ethylene generated by fruit, thus extending fruit ripening time, keeping fruit fresh. It can be widely used as food packaging materials. The composite film also has a good oxygen barrier property and has a good efficiency to remove bacteria. Therefore it can be widely used in the pharmaceutical industry. The preparation method is scientifically sound, simple, and has high level of operability, thus making it possible for batch preparation.
