Description
Technical field
The present invention relates to a kind of protection against the tide cellophane cover and preparation method thereof.
Background technology
Protection against the tide be exactly prevent in the air humidity too high, the humidity of air is too high to make mycete Fast-propagation, and mycete is not only
Article moldy metamorphism can be made, also can make the various disease of the old man of hypoimmunity, childhood infection simultaneously, the whole world every year because moist,
The economic loss causing of going mouldy is up to hundreds billion of dollars.Moistureproof paper has certain moisture protection, its moistureproof rate minimum 15%
More than.
However, existing packaging for foodstuff is many to be packed using plastic sheeting, such as various prepared for raw material with polyethylene
Thin film is although thin and durable, but when using, plastic sheeting easily produces electrostatic, and then makes the substantial amounts of ash of surface adsorption
Dirt, the health usage safety performance of impact plastic sheeting, furthermore, environmental pollution can be caused using plastic sheeting, with for moulding in a large number
The degradation speed of material thin film is slow, and because dispersion uses, leads to recovery difficult, once user whips to abandon, plastic sheeting buries
In soil, cannot degrade for a long time, soil can be affected, and then pollute environment.
Therefore, in sum, existing plastic sheeting has the performance such as moistureproof, waterproof, airtight, heat sealable, to business
Product play good protection effect, but compared with cellophane, it has easily generation electrostatic, not dust-proof, kink property difference etc. and asks
Topic.
