Abstract

The utility model discloses a package composite membrane with heat-sealed inner layer and outer layer, which is characterized by sequentially comprises an outer heat-sealed layer, a first gluing layer, an intermediate layer, a second gluing layer and an inner heat-sealed layer from outside to inside, wherein the outer heat-sealed layer and the intermediate layer are glued via the first gluing layer, the intermediate layer and the inner heat-sealed layer are glued via the second gluing layer, and the outer heat-sealed layer and the inner heat-sealed layer are polyethylene layers or casting polypropylene layers. A package bag made of the composite membrane is more attractive in appearance, intermediate banding edges can be omitted, and more materials are saved.

Description

A kind of internal layer and the outer packaging composite film that seals
Technical field
The utility model belongs to packaging composite film structure-design technique field, is specifically related to a kind of internal layer and the outer packaging composite film that seals.
Background technology
Packaging composite film in the market mostly is that internal layer is a hot sealing layer, and self-styled through hot sealing layer in the process of bag, there is a middle edge sealing in the packaging bag meeting that makes like this, and profile is not attractive in appearance, and is unfavorable for saving in material.
Summary of the invention
To the above-mentioned deficiency that exists in the prior art, the utility model a kind of complex film that carries out inside and outside heat-sealing is provided, the packaging bag of adopting this complex film to process can be saved middle edge sealing, good looking appearance, saving in material.
The technical scheme that realizes the utility model purpose is:
A kind of internal layer and the outer packaging composite film that seals; From outside inwardly comprise successively outside hot sealing layer, first adhesive layer, interlayer, second adhesive layer and interior hot sealing layer; Said outer hot sealing layer and interlayer are through first adhesive layer bonding, and said interlayer and interior hot sealing layer are through second adhesive layer bonding; Said outer hot sealing layer and interior hot sealing layer are polyethylene layer or cast polypropylene layer.
In the technique scheme, said interlayer is a single layer structure.
In the technique scheme, this interlayer is polyester aluminium plating membrane or aluminium foil layer.
In the technique scheme, said interlayer also can be lamination layer structure.
The utlity model has positive effect:
The packaging composite film of the utility model is through being hot sealing layer at ectonexine, adopts this complex film can be through inside and outside hot sealing layer is carried out the involution bag when bag, thereby saves middle edge sealing, good looking appearance, and each packaging bag can be saved the material of a middle edge sealing.
Description of drawings
Fig. 1 is the structural representation of internal layer and the packaging composite film of outer heat-sealing in the utility model;
A kind of cross sectional view of the packaging bag that Fig. 2 processes for the packaging film that adopts in the utility model.
Reference numeral shown in the figure is: the outer hot sealing layer of 1-; 2-first adhesive layer; The 3-interlayer; 4-second adhesive layer; Hot sealing layer in the 5-.
The specific embodiment
(embodiment 1)
Fig. 1 and Fig. 2 have shown a kind of specific embodiment of the utility model.Wherein, Fig. 1 is the structural representation of internal layer and the packaging composite film of outer heat-sealing in the utility model, a kind of cross sectional view of the packaging bag that Fig. 2 processes for the packaging film that adopts in the utility model.
A kind of internal layer and the outer packaging composite film that seals; As shown in Figure 1; From outside inwardly comprise successively outside hot sealing layer 1, first adhesive layer 2, interlayer 3, second adhesive layer 4 and interior hot sealing layer 5; Said outer hot sealing layer 1 bonds through first adhesive layer 2 with interlayer 3, and said interlayer 3 passes through second adhesive layer, 4 bondings with interior hot sealing layer 5; Said outer hot sealing layer 1 is poly-vinyl (PE) layer with interior hot sealing layer 5, also can be cast polypropylene (CPP) layer.Said interlayer 3 is a single layer structure, and said interlayer 3 is polyester aluminizer (VM-PET) layer or aluminium foil layer, thereby guarantees that complex film has good barrier.
In addition, as last embodiment distortion: said interlayer 3 also can be lamination layer structure.
Packaging composite film in the foregoing description is through all being made as hot sealing layer at ectonexine; Adopt this complex film can be through inside and outside hot sealing layer is carried out the involution bag when bag, thereby save middle edge sealing, good looking appearance; Each packaging bag can be saved the material of a middle edge sealing, can be referring to Fig. 2.
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.
