Abstract

The utility model is related to daily bread flexible packing material technical field, the good high-barrier corn bag of specifically related to a kind of transparent flexible, the corn bag bag body internal layer is polypropylene film, and outer layer is High-barrier nylon film, and High-barrier nylon film bonds polypropylene film by adhesive.Corn bag of the present utility model, on the one hand, compared with aobvious crisp applying silicon oxide coated polyester, High-barrier nylon film is more soft, is difficult to produce slight crack and gas leakage with sharp objects collision；On the other hand, the new corn bag of this reality is only made up of High-barrier nylon film and polypropylene film this materials at two layers, with corn bag in the prior art by compared with applying silicon oxide coated polyester, nylon film, polypropylene film this trilaminate material are constituted, production cost reduction less with material, and, materials at two layers reduces the consumption of adhesive, further reduces cost, and materials at two layers need to only carry out once-combined, compounding times are reduced, so as to improve combined efficiency.

Description

A kind of good high-barrier corn bag of transparent flexible

Technical field

The utility model is related to daily bread flexible packing material technical field, and in particular to a kind of good height of transparent flexible Obstruct corn bag.

Background technology

Refering to Fig. 1, existing corn bag bag body 1 is made up of three-layer thin-film material：Outer layer be applying silicon oxide coated polyester 2, Intermediate layer is that nylon film 3, internal layer are polypropylene film 4, and be combined with each other the packaging made by above-mentioned material by adhesive Bag has good water proof, oxygen barrier function, and high mechanical strength, heat sealability is good, and the existing packed corn of corn is vacuumized can after heat-sealing Resistance to 121 degrees Celsius, the sterilization boiling of 40 minutes time in thermophilic digestion pot.Because of the material deflection of applying silicon oxide coated polyester 2 Good, the corn bag feel being composited by it is relatively endured with all one's will, and shows crisp, is touched after packaging corn formation normal product with relatively sharp object Slight crack damaged gas leakage is also easy to produce when hitting causes corn to go bad.

Utility model content

The purpose of this utility model is to be directed to deficiency of the prior art, and provides a kind of transparent flexible good high resistant Every corn bag, soft and barrier property is had concurrently.

To achieve the above object, the technical scheme that the utility model is taken is：A kind of good high-barrier of transparent flexible is beautiful Rice bag, the corn bag bag body internal layer is polypropylene film, and the corn bag bag body outer layer is High-barrier nylon film, high-barrier Nylon film bonds polypropylene film by adhesive.

Wherein, the adhesive is polyurethane.

It is preferred that, the high-barrier corn bag offers tearing port.

It should be noted that what those of ordinary skill in the art knew, High-barrier nylon film of the present utility model can be straight Connect from supplier and obtain, the utility model is to the brand and model of High-barrier nylon film and is not particularly limited.

The beneficial effects of the utility model：

A kind of good high-barrier corn bag of transparent flexible of the present utility model, existing skill is substituted with High-barrier nylon film Applying silicon oxide coated polyester in art, on the one hand, High-barrier nylon film have preferably block water, oxygen resistance, it is important that Compared with aobvious crisp applying silicon oxide coated polyester, High-barrier nylon film is more soft, is difficult to collide generation with sharp objects Slight crack and gas leakage；On the other hand, the new corn bag of this reality is only made up of High-barrier nylon film and polypropylene film this materials at two layers, With corn bag in the prior art by compared with applying silicon oxide coated polyester, nylon film, polypropylene film this trilaminate material are constituted, Less with material, production cost reduction, moreover, materials at two layers reduces the consumption of adhesive, further reduces cost, materials at two layers It only need to carry out once-combined, compounding times be reduced, so as to improve combined efficiency.

Brief description of the drawings

Fig. 1 is the structural representation of corn bag bag body in the prior art.

Fig. 2 is a kind of structural representation of the good high-barrier corn bag bag body of transparent flexible of the utility model.

Reference：

1- existing corn bags bag body, 2- applying silicon oxides coated polyester, 3- nylon films, 4- polypropylene films, 5- this reality New corn bag bag body, 6- High-barrier nylon films.

Embodiment

The utility model is further described with the following Examples.

Refering to Fig. 2, a kind of embodiment of the good high-barrier corn bag of transparent flexible of the utility model, the new corn bag of this reality Bag body 5 internal layer is polypropylene film 4, and new corn bag bag body 5 outer layer of this reality is High-barrier nylon film 6, High-barrier nylon film 6 Polypropylene film is bonded by adhesive.

In the present embodiment, adhesive is polyurethane.Have with low cost, bond effect good as adhesive using polyurethane Advantage.

In the present embodiment, high-barrier corn bag offers tearing port（It is not shown）.Specifically, the tearing port is opened in height Obstruct the edge sealing of corn bag（It is not shown）On.

Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general Lead to it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from this The spirit and scope of utility model technical scheme.
