Abstract
The utility model provides a three -layer biaxially oriented polypropylene pearly -lustre printing film which characterized in that: including the trilamellar membrane structure, constitute by film skin, film intermediate level and film inlayer in proper order to interior by outer, film skin and film inlayer be the propylene copolymer membrane. By adopting the above structure, the utility model the film inlayer and the film that are equipped with propylene copolymer through the adoption are outer, make it possess better pearly -lustre color and luster, adopt its distinctive structure proportion moreover, make the membrane can possess better light -proofness ability to the whiteness is high, and the three -layer form -ing technology that adopts can effectively strengthen the deflection of membrane, makes it possess good bond properties.
Description
Technical field
The utility model relates to a kind of film, especially a kind of three layers of Biaxially oriented polypropylene pearly-lustre print film.
Background technology
Paper products are mounted the plastic sheeting of layer of transparent, are exactly overlay film.Specifically; positions of these easy wearing and tearing of the front cover in picture description of product book publishing, the outer surface of carton, if need diaphragm, just after the printing, folding and mount one deck to it before cutting; this tunic must be very transparent; there is good toughness, homogeneous, there is no sand holes bubble; surface is very smooth; it normally polypropylene material make, it also precoating thermal plastic high polymer adhesive so that and paper to combine, printing house's hot pressing cylinder is attached to it on paper firmly.So, there has been better gloss on the surface of paper, and quality is more abundant, and prints superincumbent color and receive protection.
And printing film great majority adopted in the market are single thin film printing finished product, products characteristics and the market demand of diversification day by day can not be met, thus cause the means that reduce costs generally adopted on the market to receive restriction, can not get effective competitiveness, the scope of application is difficult to expand, for the occasion that some special performances require, individual layer printing film cannot reach standard.
Utility model content
The purpose of this utility model is to provide a kind of low-density, cost is low, whiteness is high, shading performance is good, has three layers of Biaxially oriented polypropylene pearly-lustre print film of excellent bond properties.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of three layers of Biaxially oriented polypropylene pearly-lustre print film, it is characterized in that: comprise trilamellar membrane structure, being made up of thin film exterior layer, membrane middle layer and film internal layer successively from outside to inside, described thin film exterior layer and film internal layer are COPP film.
Preferably, the structure distribution ratio of described thin film exterior layer, membrane middle layer and film internal layer is 1:3:1 or 1:4:1.
Preferably, described membrane middle layer is HOPP film.
Preferably, described thin film exterior layer, membrane middle layer and film internal layer entirety is by three screw rod hot melt co-extrusion drawing and formings.
Preferably, mutually fit tightly between described thin film exterior layer, membrane middle layer and film internal layer.
By adopting the film internal layer and the thin film exterior layer that are provided with COPP after the utility model adopts said structure, it is made to possess good pearly-lustre color and luster, and adopt its distinctive structure proportion, make film can possess better shading performance, and whiteness is high, the three formable layer technology adopted, effectively can strengthen the deflection of film, make it possess excellent bond properties.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
In figure: 1, thin film exterior layer, 2, membrane middle layer, 3, film internal layer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in the figure, a kind of three layers of Biaxially oriented polypropylene pearly-lustre print film, it is characterized in that: comprise trilamellar membrane structure, be made up of successively from outside to inside thin film exterior layer 1, membrane middle layer 2 and film internal layer 3, described thin film exterior layer 1 and film internal layer 3 are COPP film.
Preferably, the structure distribution ratio of described thin film exterior layer 1, membrane middle layer 2 and film internal layer 3 is 1:3:1 or 1:4:1.
Preferably, described membrane middle layer 2 is HOPP film.
Preferably, described thin film exterior layer 1, membrane middle layer 2 and film internal layer 3 entirety is by three screw rod hot melt co-extrusion drawing and formings.
Preferably, mutually fit tightly between described thin film exterior layer 1, membrane middle layer 2 and film internal layer 3.
Preferably, described film internal layer 3 and the pulp furnish of thin film exterior layer 1 are the COPP 99% of at least 99%, and additive or antistatic additive etc. 1%.
Preferably, the pulp furnish of described membrane middle layer 2 is 90% HOPP, pearly-lustre masterbatch and blowing agent etc. 10%.
Preferably, described thin film exterior layer 1, membrane middle layer 2 and film internal layer 3 entirety are extruded by three layers of die head, curtain coating, and biaxial tension is shaping, rolling, corona PROCESS FOR TREATMENT.
The above is preferred embodiment of the present utility model; certainly the interest field of the utility model can not be limited with this; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or equivalent replacement, do not depart from the protection domain of technical solutions of the utility model.
