Abstract

The utility model discloses a packaging film for dry drugs, which comprises an aluminum base layer, wherein a drying layer is covered on the aluminum base layer; a brown shading layer is attached to the drying layer; a polyester layer is covered on the brown shading layer; a casting polypropylene layer is arranged under the aluminum base layer. The packaging film for dry drugs has a simple structure, an excellent compressive property, an excellent damp-proof airtight property and an ability of absorbing moisture and liquid drugs scattered and leaked to the periphery caused by the damage to the package.

Description

Drying type medicine packaging film

Technical field

The utility model relates to a kind of drying type medicine packaging film.

Background technology

At present, the general medicine packaging film using, is multilayer complex films, is basement membrane greatly, at aluminium film upper surface or compound other membrane materials of lower surface mainly with aluminium film.And some medicine there are certain requirements preserving environment humidity.When liquid drug is preserved transportation simultaneously, may there is leakage unrestrained, contaminated environment.

Utility model content

The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of can absorbing moisture and the drying type medicine packaging film of the unrestrained water clock of breakage of packages liquid drug around.

The utility model solves the technical scheme that its technical matters adopts: a kind of drying type medicine packaging film, there is aluminum base layer, in described aluminum base layer, be coated with drying layer, on described drying layer 2, be attached with brown light shield layer 3, on brown light shield layer, be coated with polyester layer 4, described aluminum base layer below has cast polypropylene layer.

Further, between polyester layer, light shield layer, drying layer, aluminum base layer, cast polypropylene layer, by adhesive bond, connect.

Further, drying layer thickness is 1mm～3mm.

The beneficial effects of the utility model are: the medicine packaging film structure that the utility model provides is simple, has good shaded effect, and have good moistureproof air-tightness, can absorbing moisture and the unrestrained water clock of breakage of packages liquid drug around.

Accompanying drawing explanation

Below in conjunction with drawings and embodiments, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model.

The specific embodiment

By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.

A kind of drying type medicine packaging film as shown in Figure 1, there is aluminum base layer, in described aluminum base layer 1, be coated with drying layer 2, on described drying layer 2, be attached with brown light shield layer 3, on brown light shield layer 3, be coated with polyester layer 4, described aluminum base layer 1 below has cast polypropylene layer 5.Between polyester layer 4, brown light shield layer 3, drying layer 2, aluminum base layer 1, cast polypropylene layer 5, by adhesive bond, connect.

Brown light shield layer 3 can effectively intercept the impact of extraneous light on medicine in film.Polyester layer 3 and cast polypropylene layer 5 have good moistureproof air-tightness, can avoid medicine in film to be subject to extraneous erosion.Drying layer 2 has good hygroscopic desiccation ability, can effectively draw moisture around, keeping medicine to pack ambient humidity, light and temperature can be not too high, again can be when cast polypropylene layer 5 or aluminum base layer 1 damage, directly absorb liquid medicine in packaging film, prevent that liquid medicine water clock from polluting.Drying layer 2 thickness are preferably 2mm.

Above-mentioned embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
