Abstract
The utility model relates to a 9-micron antisticking biaxially orientated polypropylene ultrathin composite membrane which has a three-layer structure composed of an upper surface layer (1), an intermediate layer (2) and a lower surface layer (3), and homo-polypropylene is used as the base layer material of each layer. The composite membrane is characterized in that a plurality of convex parts (4) are formed on the surface of the upper surface layer (1) and the surface of the lower surface layer (3); and each convex part (4) is a crosslinking methacrylate particle, and the particle diameter of which is from 1 to 3 microns. Every two layers of the 9-micron biaxially orientated polypropylene composite membrane are not stuck, and the composite membrane can be smoothly unfolded when being used. The composite membrane can be used as base material membrane in the technologies of paper printing, paper compounding, and the like, and achieves the effect which is the same as that of a 12-micron biaxially orientated polypropylene composite membrane. In addition, the processing materials are largely saved.
Description
Technical field
The utility model relates to a kind of Biaxially oriented polypropylene composite membrane, especially relates to a kind of Biaxially oriented polypropylene 99 mu m ultra thin type compound films of anti-adhesion.Belong to field of packaging material.
Background technology
Along with rapid development of economy, the social demand of Biaxially oriented polypropylene composite membrane increases rapidly thereupon.The international market crude oil price grows steadily in the recent period, impels raw material PP (polypropylene) particle and film price also in rising trend, and the production cost that makes the composite membrane that occupies the market share 1/3 try out producer significantly improves.At present, adopt the biaxial tension laminated film thickness of stretch processes technology production on the market all in 12～18 mu m ranges.If can reduce the thickness of biaxial tension laminated film, just can reduce the production cost of composite membrane.But,, will influence the preventing adhesiving effect of film as the thickness of one-side reduction biaxial tension laminated film.Properties of product just do not reach instructions for use.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of Biaxially oriented polypropylene 99 mu m ultra thin type compound films of anti-adhesion are provided.
The purpose of this utility model is achieved in that a kind of Biaxially oriented polypropylene 99 mu m ultra thin type compound films of anti-adhesion, be divided into upper epidermis, intermediate layer and following top layer three-decker, every layer all is base material with the HOPP, on upper epidermis and following top layer up and down in two top layer HOPP base materials the adding particle diameter be the cross-linked acrylic acid methyl esters particle of 1～3 μ m as anti-stick glutinous material, the cross-linked acrylic acid methyl esters particle of greater particle size forms many projectioies on the top layer of composite membrane.
The upper and lower layer thickness of 9 μ m composite membranes as thin as a wafer, in the client's use of downstream, the easy more adhesion of the product that thickness is thin more causes disconnected film influence to be produced.Therefore, when producing 9 μ m composite membranes, add cross-linked acrylic acid methyl esters particle on the top layer, increase the top layer roughness, make between layer and the layer and accompany air, play the effect of anti-adhesion, adhesion during uncoiling, more smooth and easy; And the cross-linked acrylic acid methyl esters contains unsatisfied chemical bond, can be better and the polypropylene molecule chain combination, and reduce and produce and the downstream adds to deviate from man-hour, reduced pollution to roll surface.
To sum up, the 9 μ m Biaxially oriented polypropylene composite membranes that the utility model is produced, adhesion between film self layer and the layer, uncoiling is smooth and easy during use.Can be used as the base film of paper printing, technology such as compound, both reached and the equal effect of 12 μ m Biaxially oriented polypropylene composite membranes, saved rapidoprint again greatly.
Description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of the anti-adhesion of the utility model.
Among the figure: upper epidermis 1, centre 2, following top layer 3, projection 4.
The specific embodiment
Biaxially oriented polypropylene 99 mu m ultra thin type compound films of the anti-adhesion that the utility model is related are divided into upper epidermis 1, intermediate layer 2 and following top layer 3 three-deckers.Every layer all is base material with the HOPP, the cross-linked acrylic acid methyl esters particle that adds particle diameter and be 1～3 μ m in two top layer HOPP base materials up and down is as anti-stick glutinous material, and the cross-linked acrylic acid methyl esters of greater particle size forms many projectioies 4 on the top layer of composite membrane.
