Description
Technical field
The invention belongs to plastics technical field of membrane, and in particular to a kind of moisture absorption damp-proof plastic film for packaging.
Background technique
Plastic foil is using thin made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other thermoplastic resins
Film for packing, and is used as coating layer.Shared share is increasing on the market for plastics package and plastic packet product,
Especially composite plastic flexible package has been widely used for the fields such as food, medicine, chemical industry, wherein again with food packaging institute
Accounting example is maximum, such as beverage packaging, quick-frozen food packaging, cooking food packaging, fast food packaging etc., these products are all given
People's life brings great convenience.
Although plastic foil has brought great benefit, but with the use of plastic foil, to people's lives and
Environment brings many problems, especially causes very big pollution to environment.This is all since plastic foil can not be timely
Caused by degradation.Even if plastic foil has comparable negative effect, but can not be given up at present, it is therefore desirable to develop energy
The plastic foil enough degraded, so that under the premise of plastic foil is widely used, reduction plastic foil bring pollution etc. is negative as much as possible
Face is rung.
Summary of the invention
