New cling film appeared on the market
May 04, 2020New cling film appeared on the marketIt is reported that a new type of degradable plastic wrap was unveiled. The degradable cling film is mainly processed from shrimp shells and shells of other crustaceans. Its preservation level is far more than that of conventional cling film, which can extend the shelf life of bread and other foods twice, and also reduces the traditional cling film Bringing "white pollution". kn95 mask
According to people familiar with the situation, the important component of the new degradable cling film is chitosan, which is a class of multimeric compounds that make up animal carapace exoskeletons. People in the industry believe that chitosan is an ideal material for food storage and preservation technology. It is also easy to degrade itself and has good preservation results.
Not only that, chitosan has anti-bacterial and anti-fungal activity, and the degradable plastic wrap has the same strength and flexibility as conventional plastic wrap, and it can also effectively prevent the appearance of food from growing various types of microorganisms.
Overcome the problem of degradable plastic wrap
A basic research from a university in Zhejiang Province is expected to solve the problem of refractory conventional plastic wrap. According to relevant personnel, this research result can solve the problems in the preparation process of bio-polyester materials, which not only improves the fresh-keeping ability of the fresh-keeping film, but also achieves degradability.
In addition, it overcomes the shortcomings of solvent replacement, such as time-consuming and material-consuming (easy consumption of large amounts of solvents), and also overcomes the defects of low thermal deformation temperature and poor heat resistance common to pure biodegradable polymers, making the plastic wrap green Degradation, and achieve the purpose of keeping food fresh.
