This utility model provides a kind of Novel packing bag, it is preferable that by dry type composite molding between described PE thin layer, nylon layer, aluminum membranous layer and PET film layer.

This utility model provides a kind of Novel packing bag, it is preferable that when described bag is in folded state, described in the angle at two base angles, bottom gone to the bottom be 100 ~ 130 degree.

Advantage of the present utility model and having the beneficial effects that:

The Novel packing bag that this utility model provides, bag is made up of four kinds of base materials, it is followed successively by PE thin layer from inside to outside, nylon layer, aluminum membranous layer and PET film layer, four-layer structure is composited via dry compound machine, first coat adhesive on a substrate, it is dried through drying tunnel, solvent in adhesive is all dried, in a heated state adhesive is melted, again another kind base material is fitted therewith, it is then passed through cooling, the process of the composite with premium properties is produced after maturation process, relative to other complex methods, have the advantages that anti-chemical mediator erosion performance is excellent via this packaging bag of dry type composite molding, can be used for the situation that content condition is harsher, the intensity of bag is high simultaneously, good stability.

The Novel packing bag that this utility model provides, four-layer structure combines, and has high obstructing performance, it is possible to the gases such as exclusion of water steam, oxygen, it is ensured that internal cleaning, extends the shelf-life of packaging article.

The Novel packing bag that this utility model provides, PE with PET is combined, and PE is arranged on innermost layer, and PET is arranged on outermost layer, PE has heat sealability, conveniently seals bag, and PET has high temperature resistant, obstruct gas simultaneously, the patterns such as the features such as puncture-resistant, are also convenient for printing, the trade mark needed for addition；Nylon layer is set outside PE layer, owing to PET material ductility is the best, after adding the nylon of good-extensibility so that the ductility of bag gets a promotion, not cracky simultaneously；Add aluminum membranous layer, improve the sealing of inside, there is high intensity and the barrier properties for gases of height.

The Novel packing bag that this utility model provides, bag is collapsible, when positioned in the folded position, mainly present the shape that rectangle combines with isosceles trapezoid, simultaneously, bag dual-side and bottom are provided with inside bending, to complete to fold, when by the bending spread apart of bag, bag is then in deployed condition, entirety presents rectangle, internal capacity changes the most greatly, and the space after expansion is greatly increased, and facilitates the packaging of Large Copacity chemicals, take up room after folding the least simultaneously, facilitate depositing and transporting of bag.

The Novel packing bag that this utility model provides, self-styled bone bar can be set at bag mouth, facilitating the opening and closing of bag, the packaging for some short-distance transport or censorship article is the most applicable, is additionally provided with pull tab at bag mouth, the situation of tear occurs during the opening and closing of bag limit the most often occurring due to valve bag, pull tab is set and conveniently pulls open bone bar, inside pull tab, be additionally provided with space, convenient placement label simultaneously, easily identification, is not take up the space of bag.
