Description
Technical field
The utility model relates to food pack technical fields, and in particular to novel foodstuff retort pouch.
Background technique
Retort pouch is a kind of laminated film food bag that can be sterilized at high temperature;It has Can container and the plastics of resistance to boiling water
The advantages of both bags, food pack with it, can whole bag boiling heating carry out high-temperature sterilization, it is very convenient without refrigerating.It is existing
There is retort pouch to be typically provided aluminium film structure, retort pouch is opaque, lead to not see interior packing principle condition, to purchasing process and
Digestion process brings unfavorable factor.In addition some manufacturers are empty using the opaque defect for covering product of retort pouch, or even lane
It plays tricks, adulterates, lead consumer into a trap.
Utility model content
The purpose of this utility model is that disclosing novel foodstuff retort pouch, it is opaque to solve existing retort pouch, unfavorable
In the food show the problem of.
In order to achieve the above objectives, the utility model adopts the following technical solution:
Novel foodstuff retort pouch, including transparent self-standing bag, the printing layer set on self-standing bag outer surface, printing layer is in centre
The structure of hollow out;The peripheral sealing of self-standing bag, the inside of self-standing bag form the seal chamber for accommodating food;Self-standing bag by it is interior extremely
It include outside CPP film (CPP:Current Polypropylene, cast polypropylene), in the first of CPP film outer surface
Between film, the second intermediate coat set on the first intermediate film outer surface and the polyamide film set on the second intermediate film outer surface.
Further, first intermediate coat is PA film (PA:polyamide, polyamide) or PVDC film [PVDC:Poly
(vinylidene chloride), polyvinylidene chloride].
Further, second intermediate coat is that (PET:Polyethylene terephthalate gathers to benzene two PET film
Formic acid glycol ester) or PA film.
Further, it is connected between the CPP film and first intermediate coat using binder.
Further, it is connected between first intermediate coat and second intermediate coat using adhesive.
Further, it is connected between second intermediate coat and the polyamide film using binder.
Further, it is connected between the polyamide film and the printing layer using binder.
Further, the binder be starch adhesive, the molten type polyurethane composite dry adhesive of HT3135B ester,
At least one of molten type polyurethane composite dry adhesive of HT3135A ester.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model uses the printed-layer structure of transparent self-standing bag and hollow out, and consumer can see close in self-standing bag
Food state in seal, still transparent retort pouch ontology is conducive to the displaying of commodity after heating, also avoids some bad quotient
Family is using the opaque defect for covering product of retort pouch, or even the problem of practise fraud, adulterate, lead consumer into a trap.Internal layer
Using the structure of CPP film, heat resistance, impact resistance and heat sealability are excellent, and it is acidproof, oil and grease resistance is excellent, water steam
Vapor permeability is lower, in addition food-contact safety, therefore will not influence the flavor of built-in food.Using polyamide film conduct
Outer membrane has the characteristics that stronger punctured resistance, oxygen barrier are good and transparent good.
2, starch adhesive belongs to natural plant gum, and amylan abundance, price is lower, easy to use, nonhazardous, to reduce
Harm of the paper to human body, and be more easier to degrade, to achieve the effect that environmental protection.The molten type polyurethane dry type of HT3135B ester is compound
Adhesive and the molten type polyurethane composite dry adhesive of HT3135A ester have good adhesiveness, make to obtain between each layer
Higher peel strength, while there is certain anti-medium and corrosion resistance, make to be not easy between each layer in the long-term use process
The phenomenon that falling off, stable structure between each film layer, to ensure that the anti needling of the utility model.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the schematic elevation view of novel foodstuff retort pouch embodiment described in the utility model;
Fig. 2 is diagrammatic cross-section of the Fig. 1 along the direction M-M, at this time omitting printing layer.
In figure, self-standing bag 1;Seal chamber 11;CPP film 12;First intermediate coat 13;Second intermediate coat 14;Polyamide film
15;Hot sealing trace 16;Printing layer 2;Yin-yang zipper 3.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
The novel foodstuff retort pouch as shown in Fig. 1 and Fig. 2 embodiment including transparent self-standing bag 1, is set to 1 appearance of self-standing bag
The printing layer 2 in face, printing layer 2 are in the structure of intermediate hollow out, can see the food state of 1 inner packing of self-standing bag.
