Abstract

The utility model discloses a BOPP (Biaxially-oriented Polypropylene) laminating film. The BOPP laminating film is divided into three layers, namely a BOPP layer, an intermediate layer and a PE (Polyethylene) layer respectively, wherein the intermediate layer is a mixing layer of PE and PP (Polypropylene); the intermediate layer is bonded with the PE layer by a hot bonding way; and the thickness ratio of the intermediate layer to the PE layer is 1:1. The BOPP laminating film disclosed by the utility model is simple in structure; the bonding performance of an integrating layer of the PE and the PP and the BOPP is better, so that no bonding agent during production is needed and further the production cost is reduced and the influence on the environment is reduced.

Description

A kind of BOPP is laminated with film

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

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.

The gas permeability of PE polypropylene film is bigger, and with the increase of density, its gas permeability descends.The PE film has moisture resistance, and poisture-penetrability is little.Polyethylene film (PE) is different according to manufacturing approach and control device, can produce the product of different performances such as low-density, middle density, highdensity polyethylene and crosslinked polyethylene.

Traditional B OPP/PE is laminated with film in process of production, need use adhesive and carry out plucking, bonding, realizes the good filling and the covering of film, and like the propylene latex, this has just increased production cost.

The utility model content

The purpose of the utility model has been to provide a kind of BOPP of adhesive that need not use 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, PE layer.

Described intermediate layer is the mixed layer of PE and PP.

Described intermediate layer and PE layer are bonded together through the hot extrude mode of closing.

Described intermediate layer and PE layer thickness ratio are 1: 1.

The beneficial effect of the utility model: simple in structure; Because the conformable layer of PE and PP and the associativity of POPP are better, need not to use aborning adhesive, have promptly reduced production cost, have reduced the influence to environment again.

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, middle 2 layers, PE layer 3.

Described intermediate layer 2 is the mixed layer of PE and PP.

Described intermediate layer 2 is bonded together through the hot extrude mode of closing with PE layer 3.

Described intermediate layer 2 is 1: 1 with PE layer 3 thickness proportion.

In actual production process, the intermediate layer 2 after PP and PE merge is all fine with the associativity of POPP layer 1, PE layer 3, need not to use adhesive draw, bonding, reduced the cost of manufacturing enterprise, also reduced harmful effect simultaneously to 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.
