With the development of degradable plastic wrap, the environmental problems brought about

【Packaging and Printing Industry Network Hot Spot】 Fresh cling film is a plastic packaging material that can be used in microwave food heating, food preservation, fresh and cooked food packaging and other occasions. Among them, in terms of food preservation, plastic wrap can greatly extend the shelf life of food. The cling film is wrapped on fruits, vegetables, meat and seafood, and it extends the preservation time of the ingredients by isolating oxygen. But today, with white pollution becoming increasingly tense, plastic wrap also acts as an environmental killer. With the development of degradable plastic wrap, the environmental problems brought about by traditional plastic wrap can be solved.

Successfully developed fully degraded plastic wrap
  It is understood that a researcher has developed a new material that can replace the traditional plastic wrap. This material is made from a mixture of two natural ingredients, including shellfish and tree fibers, and is a flexible film that can be completely degraded. Compared with conventional plastics, because the new film is composed of natural organic macromolecular materials, it has good biodegradability.
  The author understands that the biodegradable film better resists the invasion of oxygen than the conventional plastic wrap, given that it has a crystal structure that is difficult for gases to pass through. Compared with popular cling film, this kind of cling film made of chitin and cellulose reduces the air permeation and filtration by more than 70%, thus greatly extending the shelf life of food ingredients and allowing food to last longer. According to reports, the biodegradable film can be made from shellfish and other wastes, which also makes the waste in the fishery far from landfills, effectively reducing environmental pollution.
