Industrial food packaging applications are all widely used.Different according to material therefor and addition plasticiser, preservative film is divided into more
Type is applicable to different occasions.
Using preservative film packaging veterinary antibiotics when fresh food, since package interior air circulation is poor, ambient humidity
Greatly, the microbial growth of package interior is easily caused, and packaged fruits and vegetables are still a biologic artifact, are carried out
The metabolic activities such as respiration are influenced easily to rot by microorganism.
At present, preservative film is mainly the preservation reached from the following aspects to food：First, inhibit or slow down fruit
The process of vegetable maturation reduces the ethylene concentration in preservative film, so as to effectively subtract by adding ethylene absorbent in preservative film
The respiratory intensity of slow fruits and vegetables slows down nutrient consumption and prolongs storage period；Second is that being acted on by controlled atmosphere, oxygen and dioxy are automatically adjusted
Change the gas concentration that carbon keeps certain, consume oxygen using respiration, improve gas concentration lwevel, reach and inhibit fruits and vegetables itself
The purpose of respiratory metabolism, while the synergistic effect of hypoxia-hypercapania are highly resistant to the functionss of hormones such as ethylene, reduce certainly
Body consumes, and achievees the effect that extend the preserving fruit and vegetable utilizing phase；Third, by adding antifoggant, the mist that moisture evaporation is formed in fruits and vegetables is avoided
Conductance causes bacteria breed.But above-mentioned fresh-keeping mode is all by the way that fruits and vegetables metabolic process is delayed to prevent aging, can not be prevented thin
Erosion of the bacterium to food.
