Abstract
The utility model provides a five layers of biaxially oriented polypropylene pearly -lustre printing film which characterized in that: constitute by membrane inlayer, membrane time inlayer, membrane middle level, membrane are time outer, the membrane is outer, the outer propylene copolymer membrane that is of membrane inlayer and membrane, and the closely laminating of machine each other between outer of time outer, the membrane of membrane inlayer, membrane time inlayer, membrane middle level, membrane. By adopting the above structure, the utility model through adopting its distinctive structure proportion, make the membrane possess and add good light -proofness ability, through adopting the foaming technique, can effectively reduce product cost moreover, the expense of reducing expenses, five layers of form -ing technology of adoption make the membrane possess good bond properties, and are durable more lastingly for membrane mechanism thickness has the design of multiple difference, increases the possibility that obtains different performance products.
Description
Technical field
The utility model relates to a kind of five layers of pearl film, especially a kind of five 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 that a kind of cost is low, bond properties good, shading performance is good, barrier property is remarkable, five layers of Biaxially oriented polypropylene pearly-lustre print film of high-stiffness.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of five layers of Biaxially oriented polypropylene pearly-lustre print film, it is characterized in that: by film inner layer, film time internal layer, film middle level, film is time outer, film is outer formed, described film inner layer and film skin are COPP film, and described film inner layer, film time internal layer, film middle level, film are time outer, film outer between mutually machine fit tightly.
Preferably, described film inner layer, film time internal layer, film middle level, film time skin, the outer field structure proportion of film are 1:1:3:1:1 or 1:1:4:1:1.
Preferably, described film inner layer, film time internal layer, film middle level, film are time outer, film outer between shaping by the overall biaxial tensiones of five screw rod hot melt co-extrusions.
Preferably, described film time internal layer and film time skin are using polypropylene screen as matrix.
The utility model to adopt after said structure by adopting its distinctive structure proportion, shading performance film being possessed added, and by employing foaming technique, effectively can reduce product cost; To reduce expenses five formable layer technology of expense, employing, make film possess good bond properties, durable more, make film mechanism thickness have multiple different design, increase the possibility obtaining different performance product.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
In figure: 1, film inner layer, 2, film time internal layer, 3, film middle level, 4, film is time outer, 5, film is outer.
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 five layers of Biaxially oriented polypropylene pearly-lustre print film, it is characterized in that: be made up of film inner layer 1, film time internal layer 2, film middle level 3, film time skin 4, film outer 5, described film inner layer 1 and film outer 5 be COPP film, and described film inner layer 1, film time internal layer 2, film middle level 3, film are time outer 4, mutual machine fits tightly between film skin 5.
Preferably, the structure proportion of described film inner layer 1, film time internal layer 2, film middle level 3, film time skin 4, film skin 5 is 1:1:3:1:1 or 1:1:4:1:1.
Preferably, shaping by the overall biaxial tensiones of five screw rod hot melt co-extrusions between described film inner layer 1, film time internal layer 2, film middle level 3, film time skin 4, film skin 5.
Preferably, described film time internal layer 2 and film time skin 4 are using polypropylene screen as matrix.
Preferably, described film inner layer 1 and the pulp furnish of film skin 5 are COPP more than 99%, antisatic additive etc. 1%.
Preferably, the pulp furnish of described film time internal layer 2 and film time skin 4 is polypropylene and titanium dioxide 100%.
Preferably, the pulp furnish in described film middle level 3 is the additives 10% such as HOPP 90%, pearly-lustre masterbatch and blowing agent.
Preferably, described film inner layer 1, film time internal layer 2, film middle level 3, film time skin 4, outer 5 entirety of film are extruded by five layers of die head, and curtain coating, 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.
