Abstract
The utility model discloses a double-layer thermal insulation polyethylene film structure, which comprises a heat sealing layer and a temperature resistant layer, wherein the temperature resistant layer is superposed on the heat sealing layer; a layer of crosslinking agent is arranged on the temperature resistant layer; the crosslinking agent is removable glue; and a layer of release paper is arranged on the crosslinking agent. The double-layer thermal insulation polyethylene film structure is formed by a multi-layer co-extrusion technology. The heat sealing layer is made of an ultralow heat sealing material, adhesive residue of an adhesive sticker is prevented from being left on clothes, and the adhesive sticker is adhered firmly; and the permanent glue is changed into the removable glue through the crosslinking agent, so that the adhesion is improved and an adhesive residue phenomenon is avoided.
Description
Technical field
The utility model relates to a kind of double thermal insulation polyethylene film structure.
Background technology
At present, the existence heat-sealing problem in process of production of the disposable thermal bag product on the market, at first, (Polyethylene PE) is difficult to seal with air-permeable layer and scalded broken easily in heat seal process common polythene.Secondly, common gum is transferred on the clothing easily, and sticking not firm.
The utility model content
For solving the problems of the technologies described above, the purpose of the utility model is to provide a kind of can solve gum and the PE air-permeable layer seals problem fast, and it is broken effectively to protect air-permeable layer not scalded, and prevents that adhesive sticker from transferring to the double thermal insulation polyethylene film structure on the clothing.
The utility model double thermal insulation polyethylene film structure comprises: hot sealing layer; Heat-resistant layer, said heat-resistant layer is layered on the said hot sealing layer.On said heat-resistant layer, further comprise one deck glue crosslinking agent.Said glue crosslinking agent is for can move glue.On said glue crosslinking agent, further comprise one deck release liners.
The utility model double thermal insulation polyethylene film structure is used multi-layer co-extruded technology.Use ultralow heat-sealable material at hot sealing layer, prevent that adhesive sticker from leaving cull on clothing, and sticking very jail, make permanent glue become high movable glue through crosslinking agent, improve viscous force like this, can not produce the cull phenomenon simultaneously.
Description of drawings
Fig. 1 is the utility model double thermal insulation polyethylene film architecture side cut-away view;
Description of reference numerals in the utility model double thermal insulation polyethylene film structure accompanying drawing:
1-hot sealing layer 2-heat-resistant layer 3-can move glue 4-release liners
The specific embodiment
Below in conjunction with accompanying drawing the utility model double thermal insulation polyethylene film structure is done further explain.
As shown in Figure 1, the utility model double thermal insulation polyethylene film structure comprises: hot sealing layer 1; Be layered in the heat-resistant layer 2 on the hot sealing layer 1, comprise further that on heat-resistant layer 2 one deck can move glue 3, further comprise one deck release liners 4 on the glue 3 can moving.
The utility model double thermal insulation polyethylene film structure is used multi-layer co-extruded technology.Use ultralow heat-sealable material at hot sealing layer, prevent that adhesive sticker from leaving cull on clothing, and sticking very jail, make permanent glue become high movable glue through crosslinking agent, improve viscous force like this, can not produce the cull phenomenon simultaneously.
The preferred embodiment of below the utility model having been created specifies; But the utility model is created and is not limited to said embodiment; Those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
