Description

Side's end Self stand bag

Technical field

The utility model relates to yeast packaging field, especially the end, one side Self stand bag.

Background technology

Self stand bag refers to that the soft packaging bag of horizontal support structure is arranged at a kind of bottom, and not leaning on any support can stand voluntarily.Be a kind of packaged form of relative new, take advantage in all many-sides such as improving product class, strengthening shelf visual effect, carrying portable, easy-to-use, fresh-keeping and sealabilities.Often by 2 layers, 3 layers of composite process through heat seal.Self stand bag with slide fastener can be closed and repeat to open again, owing to adopting zipper-type do not close and close limited strength, is unsuitable for enclosing liquid and volatile substances in this form.Be generally used for splendid attire light-end products.Self stand bag with slide fastener is generally used for the solid of some light weights of packaging, as candy, biscuit, jelly etc.But above-mentioned traditional Self stand bag standing structure is very unstable, especially but when taking up content as (taken up thing and be less than purseful capacity two/for the moment) time less, because reasons in structure own causes this Self stand bag unstable, easily fall.

Summary of the invention

Technical problem to be solved in the utility model is to provide the end, one side Self stand bag, can solve vertical structural instability, fresh-keeping function difference problem, standing property is stable, product design is more attractive in appearance, and barrier property is excellent, and Keep the quality and freshness is good.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the end, one side Self stand bag, comprise the bag be made up of the aluminum-plastic composite membrane of four-layer structure, the bottom of bag is at the bottom of square planar, and the inwall of the top open part of bag is provided with built-in slide fastener;

In aluminum-plastic composite membrane, ecto-entad is made up of the hot sealing layer of the printed layers of 12 micron thickness, the barrier layer of 7 micron thickness, the protective cover of 15 micron thickness and 70 micron thickness successively;

Bonding by adhesive between layers.

Printed layers is biaxial tension polyethylene terephthalate film.

Barrier layer is aluminium foil film.

Protective cover is nylon membrane.

Hot sealing layer is modified polyethylene film.

The bag top of zip is provided with edge sealing.

The Self stand bag of the square end that the utility model provides, beneficial effect is as follows:

1, adopt square bottom design, bottom is square planar, and standing property is stablized, and shelf self-support effect is very attractive in appearance.

2, adopt the aluminum-plastic composite membrane of four-layer structure to make bag, overall barrier is strong, has good barrier (hinder oxygen, block water steam) characteristic, can keep yeast activity more than 2 years.

3, built-in slide fastener in upper sealing, behind packaging Kaifeng, convenient preservation, namely gets and namely uses.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Fig. 1 is the utility model structural representation;

Fig. 2 is the schematic diagram of the built-in slide fastener of the utility model;

Fig. 3 is the utility model aluminum-plastic composite membrane used.

Detailed description of the invention

As depicted in figs. 1 and 2, the end, one side Self stand bag, is characterized in that: comprise the bag 2 be made up of the aluminum-plastic composite membrane of four-layer structure, and the bottom of bag 2 is at the bottom of square planar, the inwall of the top open part of bag 2 is provided with built-in slide fastener 1;

In aluminum-plastic composite membrane, ecto-entad is made up of the hot sealing layer 4 of protective cover 7 and 70 micron thickness of barrier layer 6,15 micron thickness of printed layers 5,7 micron thickness of 12 micron thickness successively;

Bonding by adhesive between layers.

Printed layers 5 is biaxial tension polyethylene terephthalate film.

Barrier layer 6 is aluminium foil film.

Protective cover 7 is nylon membrane.

Hot sealing layer 4 is modified polyethylene film.

Bag 2 top on slide fastener 1 top is provided with edge sealing 3, need first will edge sealing 3 be had to tear during use, and recycling slide fastener 1 realizes repeating envelope and opens, and solves the little shortcoming being unfavorable for transporting of slide fastener Edge strength.

Manufacturing process of the present utility model is as follows:

First the printed layers 5 of 12 micron thickness is completed colored picture and text printing by intaglio press; again printed layers 5, barrier layer 6, protective cover 7 and hot sealing layer 4 are formed four layers of material complex film by adhesive for polyurethane is bonding by combination process; seal nylon zipper bar 1 inside sack, make square bottom through Bag Making Machine bag-shaped.

There is good barrier (hinder oxygen, block water steam) characteristic, be applicable to various solid-state, liquid, powder food product packaging.Side's bottom structure, shelf self-support effect is very attractive in appearance, and after packaging unlatching, built-in slide fastener conveniently repeats to take.
