Abstract
The utility model discloses an easily-uncovered sealing film used for a heat sealing glass container. The easily-uncovered sealing film is compounded by an enhancement layer, a blocking layer and a heat sealing layer, wherein the enhancement layer is a polypropylene screen or a polyethylene terephthalate film, the blocking layer is an aluminum foil layer, and the heat sealing layer is a hot melt adhesive layer formed by coating on a heat sealing face of the blocking layer and drying, or a polypropylene screen, or a modified polypropylene screen, or a polyamide resin film. According to the utility model, when the easily-uncovered sealing film is used, only an easily-uncovered strip is opened and pulled forcefully, the aluminum foil sealing film is uncovered, so that a canning article is taken, the easily-uncovered sealing film is simple and easy to open and operate, time-saving and labor-saving, in comparison with the conventional product, the cost is lower.
Description
Technical field
The utility model belongs to the flexible packaging film technical field, is specifically related to a kind of easy-to-uncover that is used to seal glass container and seals film.
Background technology
Glass container is the hollow object by the city of glass, for example kettle, jar, bottle, cup, bottle etc.The built-in thing of composite packaging can be the material of various states of matters, for example fruit juice, calculate in, wine or medicine etc.Traditionally its to seal generally be that metal cap parts by high-temperature sterilization are screwed on the glass container bottleneck; This packing is difficult to open usually; Its reason is that so need seal completely it, the power that applies during sealing is very big because in disinfecting process, placing thimerosal gets in the glass container; So that compress on the whole edge of the inner surface of metal cap and glass container edge; So apply very big power, or even destructive strength can open it, the cost of this sealing mode is also than higher simultaneously.
The utility model content
The purpose of the utility model provides the comparatively convenient and lower-cost easy-to-uncover that is used to seal glass container of a kind of open operation and seals film.
Realize the utility model technical scheme be: a kind of easy-to-uncover that is used to seal glass container seals film, is composited by enhancement layer, barrier layer and hot sealing layer; Said enhancement layer is polypropylene rete or polyethylene terephthalate film layer; Said barrier layer is an aluminium foil layer, and said hot sealing layer is hot melt adhesive layer or polypropylene rete or modified polypropene rete or the polyamide rete that forms through oven dry on the barrier layer heat cover by being coated in.
In the such scheme, said hot melt adhesive layer is the modification unsaturated acids hot melt adhesive layer that oven dry forms, and said unsaturated acids hot melt adhesive layer is the polyester melten gel layer that supports with linoleic acid, behenic acid, eleostearic acid, maleic anhydride.
In the such scheme, said hot sealing layer is polypropylene rete or modified polypropene rete.
In the such scheme, said seal film comprise body and from body edges outstanding be prone to take off bar.
The utlity model has positive effect: (1) the utility model only need be opened in use firmly to pull and be prone to take off bar and can open said aluminum foil sealing film; Thereby take out the canning article, its open operation is simple and easy to do, and is time saving and energy saving; And compare with traditional product, cost is lower.
Description of drawings
Fig. 1 is a kind of sectional structure sketch map of the utility model;
Fig. 2 is a kind of vertical view of the utility model.
Be labeled as shown in the accompanying drawing: body 21 is prone to take off bar 22, enhancement layer 23, barrier layer 24, hot sealing layer 25.
The specific embodiment
(embodiment 1)
Fig. 1 and Fig. 2 have shown a kind of specific embodiment of the utility model, and wherein Fig. 1 is a kind of sectional structure sketch map of the utility model; Fig. 2 is a kind of vertical view of the utility model.
Present embodiment is that a kind of easy-to-uncover that is used to seal glass container seals film, sees Fig. 1 and Fig. 2, saidly seals that film comprises body 21 and outstandingly from body 21 edges is prone to take off bar 22, is composited by enhancement layer 23, barrier layer 24 and hot sealing layer 25; Said enhancement layer 23 is polypropylene rete or polyethylene terephthalate film layer; Said barrier layer 24 is aluminium foil layers, and said hot sealing layer 25 is hot melt adhesive layer or polypropylene rete or modified polypropene rete or the polyamide retes that form through oven dry on barrier layer 24 heat covers by being coated in; Said hot melt adhesive layer is the modification unsaturated acids hot melt adhesive layer that oven dry forms, and said unsaturated acids hot melt adhesive layer is the polyester melten gel layer that supports with linoleic acid, behenic acid, eleostearic acid, maleic anhydride.General preferred employing polypropylene rete or modified polypropene rete.
Present embodiment only need be opened in use firmly to pull and be prone to take off bar and can open said aluminum foil sealing film, thereby takes out the canning article, and its open operation is simple and easy to do, and is time saving and energy saving, and compares with traditional product, and cost is lower.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection domain of the utility model.
