Fill film.
Background technology：
Plastic film packaging is current fresh fruit and the upper most widely used packaging material of vegetables production.It has transparent
Property, it may be clearly seen that the situation of packaging product；It has moisture retention, it is possible to reduce the moisture loss of product increases new
Freshness；It has gas permeability, can play the role of spontaneous controlled atmosphere, extends fresh keeping time, it has leakproofness, can protect production
Product are not contaminated.
Currently, it is base that food package film used in the country, which is generally the polymer such as polyethylene, polypropylene, polyvinyl chloride,
Body, by the way that film made of the mixing such as some plasticizer, inorganic filler, antiseptic is added.On the one hand, these packaging films there is
Long disadvantage, be easy to cause white pollution, influences environment the time required to difficult to degrade or degradation；On the other hand, these packaging films
Gas permeability is bad, if the oxygen concentration in packaging film is too low or gas concentration lwevel is excessively high, fruit just will produce anaerobic respiration,
Cause the volatile materials such as ethyl alcohol, acetaldehyde accumulate, generate peculiar smell and it is different smell, reduce the flavor quality of fruit.
