Abstract
The utility model discloses a novel PET (polyethylene glycol terephthalate) laminated thin film. The novel PET laminated thin film is divided into three layers, respectively a PET layer, a middle layer and a PE (Poly Ethylene) layer; the middle layer is a mixed layer of EVA (Ethylene-Vinyl Acetate) and PP (Propene Polymer); the middle layer is adhered to the PE layer by a hot extrusion mode; and the PET layer, the middle layer and the PE layer have the thickness ratio of 0.5:1:1. The novel PET laminated thin film has simple structure; the EVA and the PP are fused and then are subjected to hot extrusion with the PE; after the EVA and the PP are fused, the binding properties between the EVA and the PET and the PE are better; and an AC (Activated Charcoal) agent does not need to be used in the production process, so that the novel PET laminated thin film is more environmental-friendly and the production cost is also reduced.
Description
Technical field
The utility model relates to a kind of plastic sheeting, is specifically related to a kind of novel PET and is laminated with film.
Background technology
The PET plastics are abbreviations of English Polyethylene terephthalate, are called for short PET or PETP.The Chinese meaning is: poly terephthalic acid class plastics mainly comprise PET PET and polybutylene terephthalate PBT.PETG is commonly called as polyester resin again, is commonly called as polyester resin.It is the condensation polymer of terephthalic acid (TPA) and ethylene glycol, is referred to as thermoplastic polyester with PBT, or saturated polyester.
The PET film is that a kind of performance is than more comprehensive packing film.Its transparency is good, and is glossy; Have good air-tightness and fragrance protectiveness; Moisture resistance is medium, and rate of perviousness descends at low temperatures.The mechanical performance of PET film is good, and its obdurability is best in all thermoplastics, and tensile strength and impact strength are more much higher than general film; And very power is good, and dimensionally stable is suitable for secondary operations such as printing, paper bag.The PET film also has good heat-resisting, cold resistance and good chemical proofing and oil resistivity.
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.
Conventional P ET/PE is laminated with film in process of production, because poor adhesion between PET and the PE need be used the AC agent in process of production and carry out plucking, this 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 PET of AC agent that need not use to be laminated with film.
The scheme of the utility model is following: novel PET is laminated with film, and described PET is laminated with film and is divided into three layers, is respectively pet layer, intermediate layer, PE layer.
Described intermediate layer is the mixed layer of EVA and PP.
Described intermediate layer and PE layer are bonded together through the hot extrude mode of closing.
Described pet layer, intermediate layer and PE layer thickness ratio are 0.5: 1: 1.
The beneficial effect of the utility model: simple in structure; Close with the PE hot extrude after merging PP with EVA, EVA and PP merge back and PET, the PE associativity is all better, need not to use in process of production the AC agent, and environmental protection more reduces production cost simultaneously.
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, PET is a PETG, and EVA is the rare alkene copolymer of ethene-acetic acid, and PE is a polypropylene.
Novel PET is laminated with film, and described PET is laminated with film and is divided into three layers, is respectively pet layer 1, intermediate layer 2, PE layer 3.
Described intermediate layer 2 is the mixed layer of EVA and PP.
Described intermediate layer 2 is bonded together through the hot extrude mode of closing with PE layer 3.
Described pet layer 1, intermediate layer 2 and PE layer 3 thickness proportion are 0.5: 1: 1.
In actual production process, close with the PE hot extrude after merging PP with EVA, EVA and PP merge back and PET, the PE associativity is all better, need not to use in process of production the AC agent, and environmental protection has more further reduced the cost of enterprise, has also reduced the harmful effect 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.
Claims (4)
