Abstract
The utility model discloses a three-layer co-extrusion biaxially-oriented aluminized polypropylene film in the field of films. The film comprises a three-layer co-extruded polypropylene top layer, a polypropylene intermediate layer and a polypropylene bottom layer, wherein the polypropylene intermediate layer is arranged at the bottom of the polypropylene top layer; the polypropylene bottom layer is arranged at the bottom of the polypropylene intermediate layer; and an aluminized layer is arranged at the top of the polypropylene top layer or the bottom of the polypropylene bottom layer. The three-layer co-extrusion biaxially-oriented aluminized polypropylene film has a simple structure; as the aluminized layer is arranged at the top of the polypropylene top layer or the bottom of the polypropylene bottom layer, the tensile strength and the impact strength of the film are enhanced; as the aluminized layer has better water-vapor isolating capability, the water-vapor separation effect of the film is improved; and the three-layer co-extrusion biaxially-oriented aluminized polypropylene film can be used in the fields of food package, fresh flower package, medicine package and the like.
Description
Technical field
The utility model relates to a kind of film, particularly a kind of polypropylene film.
Background technology
Bidirectional stretching polypropylene film is that recent two decades grows up, be used as high-grade goods (such as cigarette, food, medicine, clothes, audio-visual product etc.) packaging material, printing is laminated with base material and glue coating adhesive tape base material etc., such film has extremely clearly transparency, the glossiness that light is bright-coloured and good barrier property, and suit in packing, coating, the operation of process high speed such as be laminated with, has high economic worth, become at present new high-tech industry in the ascendant, but the polypropylene film thickness of producing at present is thick, tensile strength and impact strength are low, has low water vapor barrier property, restricted application.
The utility model content
The purpose of this utility model provides a kind of three-layer co-extruded biaxial tension polypropylene film of aluminizing, and has solved the deficiencies in the prior art, so that film thickness is thin, and tensile strength, excellent in cushion effect, water vapor rejection is effective.
The purpose of this utility model is achieved in that a kind of three-layer co-extruded biaxial tension polypropylene film of aluminizing, comprise three-layer co-extruded polypropylene top layer, polypropylene intermediate layer and polypropylene bottom, the bottom of described polypropylene top layer arranges the polypropylene intermediate layer, the bottom in polypropylene intermediate layer arranges the polypropylene bottom, and the bottom of the top of described polypropylene top layer or polypropylene bottom arranges aluminium coated.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, by being provided with aluminium coated at the top of polypropylene top layer or the bottom of polypropylene bottom, tensile strength and the impact strength of film have been strengthened, and aluminium coated has preferably steam isolating power, thereby has improved the water vapor rejection effect of film.The utility model can be applicable to the fields such as packaging for foodstuff, fresh flower packing, medicine packing.
For so that the thickness of film is thinner, the distance between the lower surface of the upper surface of described polypropylene top layer and polypropylene bottom is less than or equal to 15 microns.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the another kind of structural representation of the utility model.
Wherein, 1 polypropylene top layer, 2 polypropylene intermediate layers, 3 polypropylene bottoms, 4 aluminium coateds.
The specific embodiment
The polypropylene film of aluminizing of a kind of three-layer co-extruded biaxial tension as shown in Figure 1, comprise three-layer co-extruded polypropylene top layer 1, polypropylene intermediate layer 2 and polypropylene bottom 3, the bottom of polypropylene top layer 1 arranges polypropylene intermediate layer 2, the bottom in polypropylene intermediate layer 2 arranges polypropylene bottom 3, the bottom of the top of polypropylene top layer 1 or polypropylene bottom 3 arranges aluminium coated 4, and the distance between the lower surface of the upper surface of polypropylene top layer 1 and polypropylene bottom 3 is less than or equal to 15 microns.
The utility model is not limited to above-described embodiment; as shown in Figure 2; the bottom that aluminium coated 4 is arranged on polypropylene bottom 3 also should fall into protection domain of the present utility model; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
