Abstract
The utility model provides an aluminium-plated PET (Polyethylene Terephthalate) film, which solves the problem of bad barrier property of the existing PET film. The aluminium-plated PET film comprises a vacuum aluminium-plated layer, a PET layer, a PE (Polyethylene) layer and a CPP (Chlorinated Polypropylene) layer which are arranged in sequence from outside to inside, wherein the PE layer and the CPP layer are bonded together by a hot-extrusion manner; and the PET layer and the PE layer are bonded together by a bonding agent. The aluminium-plated PET film provided by the utility model has the advantages that since the vacuum aluminium-plated layer is arranged on the outer side surface of the PET layer, the strength, the heat resistance and the air barrier property of the PET film can be improved; the strength is high, the heat resistance is good and the barrier effects for water and air are good.
Description
Technical field
The utility model relates to a kind of aluminum plated PET film of PET film, particularly a kind of high barrier.
Background technology
The PET film, being pet film, is the best a kind of barrier macromolecular material of combination property, has good physics and chemical characteristic, water imbibition is low, dimensional stability is very high, good barrier property, acid-resisting and oil-resisting, is widely used in the packings such as food, beverage.The steam barrier of PET belongs to low scope, but barrier properties for gases is very excellent, can carry out controlled atmospheric packing to following food with the PET film, cause rotten food (fatty foods) as oxidation, have a liking for aerobe and cause rotten food (rice cake), also have good fragrance protectiveness in addition, be used for packing even the coffee package of cure foods abroad.Therefore, the development space of PET film is very huge.But the PET film is at the needs that can't satisfy some extra package contents (as medicine) aspect intensity, hear resistance, the barrier properties for gases, thus the further developing of restriction PET film.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed the aluminum plated PET film that a kind of cost is low, intensity is high and the water proof trapping is effective.
The purpose of this utility model can realize by following technical proposal: a kind of aluminum plated PET film, it is characterized in that, described membrane structure comprises vacuum aluminium coated layer, pet layer, PE layer and CPP layer from outside to inside successively, described PE layer and CPP layer are bonded together by the hot extrude mode, and described pet layer and PE layer are bonded together by adhesive.
In the technical program, the PET formal name used at school is PETG, and the PE formal name used at school is polyethylene, and the CPP formal name used at school is cast polypropylene.
In above-mentioned aluminum plated PET film, the thickness proportion of described pet layer and CPP layer is 1:4.
In above-mentioned aluminum plated PET film, the thickness proportion of described vacuum aluminium coated layer and pet layer is 1:5.
In above-mentioned aluminum plated PET film, described adhesive is ultraviolet cured adhesive or polyurethane glue.
Compared with prior art, this aluminum plated PET film adopts PE and CPP coextruded layer as basic unit, and cost is lower, and the pet layer surface is provided with vacuum aluminium coated layer, characteristics with high barrier, can substitute aluminum foil composite, and aluminum layer thickness can select arbitrarily as required, aluminium coated can arrange thin more much than aluminium foil, cost is lower, aluminium coated electric conductivity is good simultaneously, can eliminate electrostatic influence, and range of application is wider.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, vacuum aluminium coated layer; 2, pet layer; 3, PE layer; 4, CPP layer.
The specific embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
With reference to Fig. 1, this aluminum plated PET film comprises vacuum aluminium coated layer 1, pet layer 2, PE layer 3 and the CPP layer 4 that is combined with each other from outside to inside, PE layer 3 and CPP layer 4 are bonded together as basic unit by the hot extrude mode, pet layer 2 and PE layer 3 are bonded together by ultraviolet cured adhesive, and vacuum aluminium coated layer 1 covers on the lateral surface of pet layer 2 by direct injection vacuum coating.
Can also be bonding by polyurethane glue between pet layer 2 and the PE layer 3 in the utility model.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as vacuum aluminium coated layer 1, pet layer 2, PE layer 3, CPP layer 4 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
