Abstract
The utility model discloses a multilayer film prepared by a co-extrusion blow molding film machine and aims to provide the multilayer film prepared by the co-extrusion blow molding film machine to overcome the defects of single performance, multiple procedures, high additional cost, large environment pollution and the like of traditional monolayer or multi-layer composite films. The multilayer film comprises a surface layer, a bonding layer and a bottom layer and is characterized in that the bonding layer is positioned between the surface layer and the bottom layer; and the surface layer is bonded with the bottom into a whole through the bonding layer. The multilayer film is mainly used for foods, medicines, household chemical products, agricultural greenhouses, hydraulic engineering, environmental engineering and the like to serve as a barrier packaging film, a shrink film and a hollow plastic film.
Description
Technical field:
The utility model relates to a kind of plural layers, relates in particular to a kind of plural layers that are equipped with coextrusion blow film mechanism.
Background technology
Along with expanding economy, people are more and more higher to the requirement of packing, and multi-layer co-extruded film more and more is subjected to people's favor.Current packaging is single with the single thin film performance, makes multi-layer compound film as need, needs to adopt modes such as the compound or solvent of dry types is compound to realize a plurality of single thin films, operation is many, so the fringe cost height that causes, big to film and environmental pollution, sanitation performance is bad.And for common plural layers, from a structural point, functional layer also exists the film that causes because of the film surfaces externally and internally material difference phenomenon of curling very little simultaneously, a little less than gas and water resistance separating performance, the mechanics of film and optical property also a little less than.
Summary of the invention
The purpose of this utility model is to provide short plural layers that are equipped with coextrusion blow film mechanism, to overcome the drawback of conventional monolayers or multi-layer compound film.
For achieving the above object, technical solution of the present utility model is: a kind of plural layers that are equipped with coextrusion blow film mechanism, comprise superficial layer, adhesive layer and bottom, it is characterized in that: described adhesive layer 2 is between superficial layer 1 and bottom 3, and superficial layer 1 is bonding in aggregates by adhesive layer 2 and bottom 3.
Described superficial layer 1 is polyethylene or layer of polypropylene foil.
Described bottom 3 is polypropylene or ethylene-vinyl acetate copolymer thin layer.
Described adhesive layer 2 is polyvinyl alcohol adhesive layers.
The thickness of described plural layers is 25～300 microns.
The beneficial effects of the utility model are: the plural layers that are equipped with coextrusion blow film mechanism are to the good barrier property of oxygen and steam, the intensity of film and wear height, heat sealability is good, and caking property is strong, have good antifog property, coloring, be widely used at packaging field.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-superficial layer, 2-adhesive layer, 3-bottom.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises superficial layer, adhesive layer and bottom, it is characterized in that: described adhesive layer 2 is between superficial layer 1 and bottom 3, and superficial layer 1 is bonding in aggregates by adhesive layer 2 and bottom 3.
Described superficial layer 1 is polyethylene or layer of polypropylene foil.
Described bottom 3 is polypropylene or ethylene-vinyl acetate copolymer thin layer.
Described adhesive layer 2 is polyvinyl alcohol adhesive layers.
The thickness of described plural layers is 25～300 microns.
The plural layers that this product is equipped with the multi-layer co-extruded inflation film mechanism of novel employing are than the single thin film of various same materials, the utility model one-shot forming, the fringe cost of having saved operation and therefore having been caused, environmental-protecting performance is good simultaneously, avoided compound as dry type, solvent is compound etc. to the pollution of film and environment, have characteristics such as energy-conserving and environment-protective, the leftover pieces recovery utilization rate is up to more than 90%, and self can not produce secondary pollution.
Than similar laminated film, the utility model from a structural point, use co-extrusion technology and can increase multiple function film, help being reduced in the ratio of material of costing an arm and a leg under " mass excess " situation, thereby the conservation cost helps solving because of phenomenons such as the different films that cause of film surfaces externally and internally material curl.
Claims (5)
