Abstract
The utility model discloses a BOPP (Biaxially-oriented Polypropylene) laminated film. The BOPP laminated film is divided into three layers, which are respectively a BOPP layer, a middle layer and a PP layer, wherein the middle layer is a mixed layer of PP and PE; the middle layer and the PP layer are bonded with each other by a hot extrusion method; and the thickness ratio of the middle layer and the PP layer is 1:1. The BOPP laminated film disclosed by the utility model has the advantages as follows: a simple structure is achieved; as the PE cannot be necked, the PE is hotly extruded together with the PP after being fused with the PP, so that less waste edges of a film body are generated and production cost is reduced; meanwhile, better bonding property between the fused PE and PP and the BOPP is obtained, the use of an adhesive in the production process is not needed and greater environment friendliness is achieved.
Description
Technical field
The utility model relates to a kind of plastic sheeting, is specifically related to a kind of BOPP and is laminated with film.
Background technology
Polypropylene (PP) film is one of common heat shrink films material; Characteristics such as have that protection against the tide, mechanical strength are high, dimensional stability is good, light weight, nontoxic, odorless, printing performance are good are widely used in label printing, coating, cigarette, food pack, vacuum aluminum-coated, capacitor etc.
BOPP is the abbreviation of " Biaxially Oriented Polypropylene ", and the BOPP film is a bidirectional stretching polypropylene film.The BOPP film is a kind of very important flexible packing material, the BOPP film is colourless, do not have smell, tasteless, nontoxic, and have high tensile, impact strength, rigidity, obdurability and the good transparency.The BOPP film surface can be low, need carry out corona treatment before gluing or the printing.After corona treatment, the BOPP film has good printing adaptability, can chromaticity printing and obtain exquisite appearance, thereby the surface material of making compound film commonly used.
Traditional B OPP/PP is laminated with film in process of production, because the constriction amount of PP is big, the slitter edge that causes producing is many, also will use adhesive in process of production simultaneously, increases production cost, also can exert an influence to ecological environment.
The utility model content
The purpose of the utility model has been to provide a kind of waste material of generation few, and need not use the BOPP of adhesive to be laminated with film.
The scheme of the utility model is following: a kind of BOPP is laminated with film, and described BOPP is laminated with film and is divided into three layers, is respectively BOPP layer, intermediate layer, PP layer.
Described intermediate layer is the mixed layer of PP and PE.
Described intermediate layer and PP layer are bonded together through the hot extrude mode of closing.
Described intermediate layer and PP layer thickness ratio are 1: 1.
The beneficial effect of the utility model: simple in structure; Because PE does not have constriction, after merging PP, closes use PE with the PP hot extrude, and the feasible film body slitter edge that produces has still less reduced production cost, and is better with the BOPP associativity after the fusion of PE and PP simultaneously, need not to use in process of production adhesive, more environmental protection.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with Fig. 1 the utility model is further specified.
In the utility model, POPP is a bidirectional stretching polypropylene film, and PP is a polypropylene, and PE is a polyethylene.
A kind of BOPP is laminated with film, and described BOPP is laminated with film and is divided into three layers, is respectively BOPP layer 1, intermediate layer 2, PP layer 3.
Described intermediate layer 2 is the mixed layer of PP and PE.
Described intermediate layer 2 is bonded together through the hot extrude mode of closing with PP layer 3.
Described intermediate layer 2 is 1: 1 with PP layer 3 thickness proportion.
In actual production process, the constriction amount after PE and PP merge is significantly smaller than the constriction amount of PP, like this when production BOPP is laminated with film; The slitter edge that produces will be still less; Manufacturing enterprise's cost has obtained reduction, and the associativity of adding PE and PP fusion back and POPP is better, need not to use adhesive; Further reduced the cost of enterprise, also reduced harmful effect environment.
Although preceding text have given to describe in detail and explanation to the specific embodiment of the utility model; But what should indicate is; We can carry out various equivalences to above-mentioned embodiment according to the conception of the utility model and change and modification; When the function that it produced does not exceed spiritual that specification and accompanying drawing contain yet, all should be within the protection domain of the utility model.
