Abstract
The utility model particularly relates to a closing cap membrane that can repeatedly open, including inlayer and skin, its characteristic with, the inlayer with the skin carries out the rigid coupling through the bond line, outer polydiethylene terephthalate membrane or the polyamide membrane of adopting, the inlayer adopts autohension polymer resin. The utility model provides a pair of outer polydiethylene terephthalate membrane or the polyamide membrane of adopting of closing cap membrane that can repeatedly open for the thickness of this closing cap membrane reduces 40%, even the inlayer adopts autohension polymer resin still can repeatedly open under the influence that has the oil stain and to paste by this closing cap membrane simultaneously.
Description
Technical field
The utility model relates to composite membrane technology field, particularly relates to a kind of capping film repeating to open.
Background technology
Now, along with continuous progress and the development of science and technology, the requirement of people to quality of life is more and more higher.In packaging industry, plastic flexible packaging material except require it to meet requirement that different product packaging quality and efficiency etc. improves day by day, also require further its must to economize on resources, economize energy.
At present; people are when the prepared food using some plastic packing boxes to be equipped with; often there will be food to eat up; need to have torn on capping membrane cover; general capping film is all adopt polyamide membrane or aluminium foil or paper; it is cannot stick up after capping film is torn that these capping films have a unified characteristic again, makes the food of plastic packing box be placed on outdoor and there will be rotten or be positioned in refrigerator the situation that there will be taint of odour.
Utility model content
The utility model provides a kind of capping film repeating to open, and solves the situation that capping film can not repeat to open and paste.
The purpose of this utility model realizes by following technical scheme: a kind of capping film repeating to open, comprise internal layer and skin, it is characterized in that, described internal layer and described skin are undertaken affixed by bonding coat, described skin adopts polyethylene terephthalate film or polyamide membrane, and described internal layer adopts self-viscosity high-molecular resin.
A kind of capping film repeating to open that the utility model provides, preferably, the material of described bonding coat is polyurethane binder.
A kind of capping film repeating to open that the utility model provides, preferably, described outer field thickness is 0.010mm to 0.015mm.
A kind of capping film repeating to open that the utility model provides, preferably, the thickness of described internal layer is 0.005mm to 0.0075mm.
Preferential and beneficial effect of the present utility model is: compared with prior art, a kind of capping film skin repeating to open that the utility model provides adopts polyethylene terephthalate film or polyamide membrane, the thickness of this capping film is made to reduce 40%, even if internal layer adopts self-viscosity high-molecular resin still can repeat to open and paste under the impact having oil stain by this capping film simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, preferred implementation of the present utility model is just preferably described, wherein,
A kind of schematic diagram repeating the capping film opened that Fig. 1 provides for the utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of capping film embodiment repeating to open of the utility model is described further.
A kind of capping film repeating to open in Fig. 1, comprise internal layer 1 and outer 2, its feature with, described internal layer 1 and described outer 2 is undertaken affixed by bonding coat 3, described outer 2 adopt polyethylene terephthalate film or polyamide membrane, and described internal layer 1 adopts self-viscosity high-molecular resin.
The material of described bonding coat 3 is polyurethane binder.
The described thickness of outer 2 is 0.010mm to 0.015mm.
The thickness of described internal layer 1 is 0.005mm to 0.0075mm.
Compared with prior art, a kind of capping film repeating to open outer 2 that the utility model provides adopts polyethylene terephthalate film or polyamide membrane, the thickness of this capping film is made to reduce 40%, even if internal layer 1 adopts self-viscosity high-molecular resin still can repeat to open and paste 6 ~ 8 times under the impact having oil stain by this capping film simultaneously.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
