Description
Technical field
The utility model is related to a kind of plastic foil, specifically a kind of moisture absorption damp-proof plastic film for being used to pack.
Background technology
With the development and the raising of living standards of the people of science and technology, the use of packaging material is more and more extensive.Packaging film is wide
General to be applied to food, building, chemical industry, medicine and other fields, plastic foil is all obtained extensively with its cheap cost in numerous areas
Use.Mouthful often life in commonly use typewriting hood, laundry hood, handbag, raincoat, rain cape, blanket-cover, slipmat, shopping bag,
Operation dress, operation set, bedcover etc. often all include bright outer surface and lucifuge and the poor inner surface of color is constituted, and one
It is so that all articles are specious, two be cost-effective, reduces the usage amount of bright colors additive.But, current is double-colored
Plastic foil is double-decker, because film very thin thickness itself so that the color of dual-color plastic film is interfered, thus vivid
Outer surface seems not bright-coloured enough, have impact on the outward appearance of article.Existing plastic film for wrapping is all some common films,
There is no feature, the article for having high dry packing requirement for some just seems unable to do what one wishes.

The edge closure of film and interior plastic foil and by the first damp-proof layer, the second damp-proof layer, the first monochromatic plastic foil, the second monochromatic plastic foil
It is sandwiched therebetween with the 3rd monochromatic plastic foil, multiple micropores are evenly arranged with interior plastic foil, the damp-proof layer is powder
Last shape desiccant layer.
It is used as further program of the utility model：A diameter of 20-30 microns of the micropore.
It is used as further program of the utility model：The diameter of the particle of the powdered drier is less than more than 30 microns
40 microns.
It is used as further program of the utility model：The outer plastic foil is polyethylene plastic film.
It is used as the utility model further scheme：The thickness of the polyethylene plastic film is 1-1.2mm.
Compared with prior art, the beneficial effects of the utility model are：Due to by coextrusion process by three layers of monochromatic plastics
Together, it is a kind of color, the second monochromatic plastic foil and the 3rd monochromatic plastic foil that can cause the first monochromatic plastic foil to film combination
It is so, just monochromatic by first because the second monochromatic plastic foil just forms the background color film of the 3rd monochromatic plastic foil for another color
Plastic foil and the 3rd monochromatic plastic foil are separated, and the color of the first monochromatic plastic foil and the 3rd monochromatic plastic foil just will not interfere with, and increase
The vividness of dual-color plastic film surface color and polish is added, due to the first monochromatic plastic foil, the second monochromatic plastic foil and the 3rd monochromatic modeling
Material film accounts for 25%-30%, 5%-10% and 25%-10% of three-layer co-extruded plastic film gross thickness respectively so that two different colors of list
Color plastic foil can preferably show oneself single color, and the usual first monochromatic plastic foil is the bright color of outer surface, maximum
The production cost saved additive, reduced plastic foil of limit, due to being provided with two inside outer plastic foil and interior plastic foil
Layer damp-proof layer, with preferable moisture absorption humidity resistance, fully meets the high request of packing business.
Brief description of the drawings
Fig. 1 is the structural representation of the moisture absorption damp-proof plastic film for packaging.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
