Abstract
The utility model is related to a kind of transparent composite covering film for polyester substrate container, by outer and in include PET base membrane layer, the first gluing oxidant layer, high barrier PVDC coating, the second gluing oxidant layer and hot sealing layer successively, the second gluing oxidant layer is dual-component polyurethane adhesive, and the hot sealing layer seals film layer for co-extrusion PE.Compared with the prior art, the beneficial effects of the utility model are：Transparency is good, can watch the state of content；Using high-barrier coating material, extend the shelf-life of content；Use co-extrusion film as hot sealing layer, the heat sealability of epiphragma and container can be improved and easily take off performance.
Description
Technical field
The utility model is related to a kind of composite covering film, more particularly to a kind of transparent composite cover for polyester substrate container
Film.
Background technology
If transparent composite covering film of the prior art wants transparency good, barrier will be deteriorated, in addition, existing transparent
The heat sealability of composite covering film and easily take off unstable properties.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of transparent composite covering film for polyester substrate container, with
Solve deficiency of the prior art.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions：
A kind of transparent composite covering film for polyester substrate container is provided, by outer and in include successively PET base membrane layer, first
Gluing oxidant layer, high barrier PVDC coating, the second gluing oxidant layer and hot sealing layer.
In technique scheme, the second gluing oxidant layer is double-component polyurethane glue stick.
In technique scheme, the hot sealing layer seals film layer for co-extrusion PE.
Compared with the prior art, the beneficial effects of the utility model are：
Transparency is good, can watch the state of content；Using high-barrier coating material, extend guaranteeing the quality for content
Phase；Use co-extrusion film as hot sealing layer, the heat sealability of epiphragma and container can be improved and easily take off performance.
Description of the drawings
The accompanying drawing for constituting a part of the present utility model is used for providing further understanding to of the present utility model, and this practicality is new
The schematic description and description of type is used for explaining the utility model, does not constitute to improper restriction of the present utility model.?
In accompanying drawing：
Fig. 1 shows the utility model for the structural representation of the transparent composite covering film of polyester substrate container.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
It should be noted that in the case of not conflicting, the embodiment in the utility model and the feature in embodiment can
To be mutually combined.
With reference to shown in Fig. 1, the utility model is used for the transparent composite covering film of polyester substrate container, by outer and in include successively
PET base membrane layer 1, the first gluing oxidant layer 2, high barrier PVDC coating 3, the second gluing oxidant layer 4 and hot sealing layer 5.
In the technical program, the second gluing oxidant layer 4 is double-component polyurethane glue stick, and hot sealing layer 5 is co-extrusion PE heat-sealing film
Layer.Extraordinary first gluing oxidant layer 2 is coated with first on PET base membrane layer 1, then applies high barrier in the first gluing oxidant layer 2
PVDC coating 3, using double-component polyoxy fat adhesive by coated PET film bonding co-extrusion PE heat-sealing film, will preferably be combined
Composite membrane insert 50 DEG C of curing chambers curing 36-40 hours after can use.
From above-described embodiment as can be seen that advantage of the present utility model is：
Transparency is good, can watch the state of content；Using high-barrier coating material, extend guaranteeing the quality for content
Phase；Use co-extrusion film as hot sealing layer, the heat sealability of epiphragma and container can be improved and easily take off performance.
Above specific embodiment of the utility model has been described in detail, but the utility model be not restricted to above
The specific embodiment of description, which is intended only as example.To those skilled in the art, any equivalent modifications and substitute also all
Among category of the present utility model.Therefore, done impartial conversion under without departing from spirit and scope of the present utility model
And modification, should all cover in the range of the utility model.
