Abstract

The utility model discloses a folding packing bag, wherein, a bag body in the utility model takes the shape of a square; a facade and a reverse side of the bag body are bended and extended downwards and then sealed, folded and bonded to form a bottom surface of the bag body; a left side and a right side of the bag body are bended and extended downwards to form a triangular folding surface which is positioned on the bottom surface; the folding surface is integrated into a whole with the bottom surface. The utility model is formed at a time by means of cementation, thereby bonding procedures and processing time are saved; the productivity is improved; and the production cost is reduced. Because the bag body is folded into the square shape, the utility model has large capacity and is particularly suitable for packing lump foodstuffs; moreover, because a transparent observation window is arranged on the left side or the right side, status of the foodstuffs is conveniently observed.

Description

folding bag

technical field

The utility model relates to a food packaging bag, in particular to a folding packaging bag with simple folding process and large capacity.

Background technique

The food packaging bags currently used in the market generally adopt three methods: 1. Cut the plastic or paper into a square and fold it in half and then bond it, and press the bottom surface and then fold and bond the four corners; 2. Cut the plastic or paper According to the specifications, it is cut into a style with four sides and the upper and lower bottom surfaces connected. When using the style, it is unfolded and joined according to the creases that have been pressed before, and then glued on the first side and the last side, and then The bottom surface is stacked alternately; 3. The bottom surface of the packaging bag is formed by one fold. These three kinds of food packaging bags can basically meet people's needs for packaging food and containing articles, but there are still the following defects: the four corners of the bottom surface of the first type of packaging bag need to be folded and bonded, which increases the bonding process; Before the bag is used, the paper pattern must be unfolded, joined and glued, which is inconvenient to use; although the third packaging bag reduces the production process, the bottom is flat and the capacity is also affected to a certain extent.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned defects of the existing packaging bags, and provide a foldable packaging bag. The utility model has simple folding process, large capacity, convenient use, quick folding and reduced production cost.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

A folding packaging bag, characterized in that: the bag body is square, the front and back sides of the bag body are bent and extended downwards, the seal is folded and bonded to form the bottom surface of the bag body, and the left and right sides of the bag body are bent and extended downwards to form a The triangular folding surface is located on the bottom surface, and the folding surface is integrated with the bottom surface; the left or right surface is provided with a transparent observation window.

The folded adhesive portion on the bottom surface of the bag body is bonded to the bottom surface.

The front and back of the foldable packaging bag are symmetrical, and the left and right sides are symmetrical.

Creases are provided on the left and right vertical midlines.

The advantage of adopting the utility model is:

The utility model is bonded and formed at one time, which reduces the bonding process, saves processing time, improves productivity, and reduces production costs; the bag body is folded into a square shape and has a large capacity, and is especially suitable for block food packaging; the left or right side There is a transparent observation window, which is convenient for observing the status of the food in the bag.

Detailed ways

A folding packaging bag, the bag body is in the shape of a rectangle, the front and back of the bag body are bent and extended downwards, the sealing is folded and bonded to form the bottom surface 1 of the bag body, and the left and right sides 8 of the bag body are bent and extended downwards to form a The isosceles triangle folded surface 2 on the bottom surface 1 has the left and right 8 bent sides as the base 3, and the front and back side bent sides as the waist 4. The folding surface is integrated with the bottom surface 1 . The folded bonding portion on the bottom of the bag body is bonded to the bottom surface, and a bonding line 5 and a bonding mark 6 are formed on the bottom surface. The front and back of the folding packaging bag are symmetrical, and the left and right sides are symmetric. Creases 7 are provided on the vertical midlines of the left and right sides 8 .

The utility model is bonded and formed at one time, which reduces the bonding process, saves processing time, improves productivity, and reduces production costs; the bag body is folded into a square shape and has a large capacity, and is especially suitable for block food packaging; the left or right side A transparent observation window 9 is provided to facilitate the observation of the status of the food in the bag.
