Description

A packaging bag that can be stacked upright on each other

【Technical field】

The utility model relates to a packaging bag made of flexible materials.

【Background technique】

Packaging bags made of flexible materials are widely used food packaging bags at present, but there is an obvious defect in the existing food packaging bags. The food packed in such packaging bags can only be placed on the shelves in an orderly manner. not stacked upright on top of each other on the shelf. Its main reason is that present flexible packaging bag all only is provided with the bag bottom that can stand upright, and the top of bag is flat, can't stack and place other things again on the top of bag. Like this, just wasted the stacking space on the shelf, reduced the placement quantity of goods. And even if the packaging bag made of flexible material is laid flat, it is also difficult to place other packaging bags or articles on it.

Existing packaging bags can only be opened and sealed at one time. When the product is not used up or the food is not eaten, most packaging bags cannot be sealed again, but can only be fastened with ropes or other methods. Like this, be unfavorable for keeping fresh, prevent pollution and guarantee sanitation. It is also not conducive to keeping food dry, and it is easy for foreign matter to enter.

【Purpose of the invention】

The purpose of the utility model is to provide a method of transporting and placing on the shelf without wasting space on the shelf, increasing the number of goods placed, and packaging bags of the same specification can be stacked on the packaging bag body.

The purpose of the utility model is also to provide a packaging bag which has good sealing effect, is convenient to open and seal, and can be opened and sealed repeatedly.

The purpose of this utility model is achieved in that:

A packaging bag that can be stacked upright with each other, including a bag body, the bag body is formed by folding and heat-pressing at least one composite film, and includes a front edge, a rear edge, and a bottom for supporting the bag. It is characterized in that it also includes a top that can be used to support other bags, and the center of the bottom and top is concave, and the periphery forms the edge supporting the top and bottom of the bag.

A packaging bag that can be stacked upright as described above is characterized in that the bag body is folded to form a front side, a back side and a bottom, and the top, wherein the bottom and the middle of the top are folded inward, so that the front side, the back side and the top The top corner is formed between the front edge, the rear edge and the bottom; the bottom and the top are formed by the front edge and the rear edge, the top corner and the top corner, The bottom corner is integrally formed by heat-press sealing the bottom corner.

A packaging bag that can be stacked upright as described above is characterized in that a bag opening is provided on the bag body. At the position of the bag opening, one side of the bag body extends for a section to form a folded edge, and the folded edge bends to cover the bag. On the opposite side of the mouth, a heat-sealing tape is arranged between the folded edge and the opposite side of the mouth of the bag, and a self-adhesive sealing tape is provided below the heat-sealing tape.

The utility model has the advantages that: the utility model can be placed upright independently, can be stacked upright with each other, and can be stacked more than two layers. Whether it is in the process of transportation or placed on the shelf, the stacking space on the shelf can be increased, the number of goods placed can be increased, and the structure is simple and convenient to place. And the bag mouth can be opened and sealed repeatedly. It is conducive to keeping fresh, preventing pollution and ensuring hygiene. Keep food dry.

[specific implementation plan]

A packaging bag that can be stacked upright, made of flexible materials, includes a bag body 1, the bag body 1 is formed by folding and hot pressing at least one composite film, and includes a front side 2, a rear side 3, and a The bottom 4 used to support this bag is characterized in that it also includes a top 5 that can be used to support other bags, and the center of the bottom 4 and the top 5 is concave, and the periphery forms a side 6 that supports the top and bottom of the bag.

After the bag body 1 is folded, the front side 2, the rear side 3, the bottom 4 and the top 5 are formed, wherein the bottom 4 and the middle 7 of the top 5 are folded inward, so that the top corners 8 and 9 are formed between the front side 2, the rear side 3 and the top 5, Bottom corners 10, 11 are formed between the front side 2, the back side 3 and the bottom 4; The top corner 8 and the top corner 9 at the end position, and the bottom corner 10 and the bottom corner 11 at the left and right ends are formed as a whole by thermocompression sealing. The thermocompression joining of the top corners 8 , 9 forms the top support side 6 , and the thermocompression joining of the bottom corners 10 , 11 forms the bottom support side 6 .

The bag body 1 is provided with a bag opening 12, and at the position of the bag mouth 12, one side 13 of the bag body 1 extends for a section to become a folded edge 14, and the folded edge 14 is bent and covered on the opposite side 15 of the pocket mouth, A heat-sealing tape 16 and a self-adhesive sealing tape 17 are arranged between the side 14 and the opposite side 15 of the pocket opening.

The positions of the heat-sealing tape 16 and the self-adhesive sealing tape 17 can be interchanged. That is, the heat-sealing tape 16 is on the top or the self-adhesive sealing tape 17 is on the top.

The heat-sealing tape 16 that is provided between the folded edge 14 and the other side 15 of the pocket forms a primary seal, and the self-adhesive sealing tape 17 that is provided with below the heat-sealing tape 16 forms a secondary seal that can be used repeatedly. After the first use, it can be sealed again with self-adhesive, and can be used repeatedly. The self-adhesive seal is located on the front of the packaging bag, so that it will not stick to the products and food in the packaging bag.
