Abstract
The utility model discloses a PET (Polyethylene Terephthalate) composite plastic shrink film which comprises a core layer, two adhesive layers and two PET blow moulding film layers, wherein the core layer is composed of PET fibre; the two adhesive layers are respectively positioned at two surfaces of the core layer, formed by adhesive, and used for connecting the core layer with the PET blow moulding film layers; the two PET blow moulding film layers are respectively positioned at the other surfaces of the two adhesive layers and formed by a PET blow moulding film; and the core layer is encircled by the PET blow moulding film layers and the adhesive layers. The PET composite plastic shrink film disclosed by the utility model not only has better high-temperature resistance performance, but also can be recycled, so that the PET composite plastic shrink film is beneficial to environmental protection; simultaneously, due to the PET composite plastic shrink film, the high-temperature resistance performance of a material is increased, so that a composite packaging material not only can be directly applied to microwave foods, but also can be directly used for baking cakes; the double baking process in the traditional baking process is omitted; and the food hygiene performance is increased.
Description
Technical field
The utility model relates to a kind of plastic sheeting, is specifically related to a kind of PET composite plastic shrink film.
Background technology
Flexible packing material is generally take packaging for foodstuff as main, and its kind has 30～40 kinds more than, and the compound number of plies is generally 2～7 layers and does not wait.The kind of laminated film is a lot, and common material has BOPP, PCV, NY, PT, PE, PP etc., production technology mainly be the printing, compound, cut or bag technique.
But in traditional production process, what printing, combination process often used is solvent type ink, benzene class organic solvent, not only poisonous but also flammable, is unfavorable for environmental protection and health, also dangerous.Although can remove most of solvent by drying system, still have certain quantity of solvent to remain in the composite membrane, these residual solvents can be moved on the contents such as food, are detrimental to health.
In addition, common flexible packing material resistance to elevated temperatures is relatively poor, as packaging for foodstuff the time, is unsuitable for for heating using microwave, can not directly toast.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of all solvent residual amounts of conventional composite packaging material that not only do not have are provided, and has reduced the pollution to environment, simultaneously improved the PET composite plastic shrink film of heat-resisting quantity.
For achieving the above object, the technical solution of the utility model is a kind of PET composite plastic shrink film of design, it is characterized in that described plastic shrink film comprises one deck sandwich layer, and is fibrous by PET; Two-layer adhesive layer lays respectively at the two sides of sandwich layer, is comprised of adhesive, is used for connecting sandwich layer and PET blowing rete; Two-layer PET blowing rete lays respectively at the another side of two-layer adhesive layer, is comprised of the PET blown film.
Wherein preferred technical scheme is, described sandwich layer is surrounded by PET blowing rete and adhesive layer.
Further preferred technical scheme is that described adhesive is the high-strength glue of acrylic acid.
Further preferred technical scheme also has, and described PET blown film thickness is 0.015～0.25mm.
Further preferred technical scheme also has, and described core layer thickness is 0.015-0.6mm.
Advantage of the present utility model and beneficial effect are that this PET composite plastic shrink film had both had preferably heat-resisting quantity, and was recyclable again, was conducive to environmental protection.Improve simultaneously the heat-resisting quantity of material in PET composite plastic shrink film, made this compound package material can directly apply to microwave food, and can be directly used in the baking of cake, omitted and turned over the baking operation in traditional roasting procedure, improved the sanitation performance of food.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
Among the figure: 1, PET blowing rete; 2, PET fibrage; 3, glue layer.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Shown in 1,3 figure, the utility model is a kind of PET composite plastic shrink film, comprises the fibrous sandwich layer of PET, and described sandwich layer both sides are the adhesive layer that adhesive forms, the another side of adhesive layer is PET blowing rete, described adhesive layer be used for boning sandwich layer and PET blowing rete.Described adhesive can be viscous adhesive water, and the sticky agent in the present embodiment is the high-strength glue of acrylic acid.
Such as Fig. 1 in conjunction with shown in Figure 2, the fibrous sandwich layer of a described PET centre at PET composite plastic shrink film, the both sides of PET composite plastic shrink film are directly combined by sticky agent by two-layer PET blowing rete, the PET fibrage just is enclosed in the centre by adhesive layer and PET blowing rete like this, and each layer of described PET composite plastic shrink film is very firm with regard to combination.Particularly tensile strength is being required when high, the PET fibrage can be thicker, and this PET composite plastic shrink film does not only have all solvent residual amounts of conventional composite packaging material, has reduced the pollution to environment, simultaneously improved heat-resisting quantity, be a kind of composite soft packaging material of real environmental protection.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (5)
