Background technology
With the continuous development of society, people’s lives rhythm is getting faster, therefore people are for convenient fresh-keeping
Food demand amount is increasing, and traditional preservative film and do not have anti-mildew effect, this allows for packaged food
Shelf-life it is shorter, cause food waste.It is very to prepare the membrane material that existing anti-mildew effect can operate with preservation field again
It is necessary.Preservative film proposes certain requirement to the performance of film, and not embrittlement under freezing conditions need to be had by essentially consisting in preservative film,
Food ontology is not pasted and with certain elasticity.And the addition of anti-mildew denaturation then needs special technique.Currently, prior art passes through poly-
The mode of the vinyl film upper and lower surface coating anti-mildew coating of chemical preservation realizes the anti-mildew denaturation of preservative film, but due to its coating sheet
Body has other chemical compositions, and food-safe generation is certain to be influenced, and the addition of spraying process will significantly improve composite membrane
Complex process degree.
