Embodiment 1

[0024] Such as figure 1 As shown, the bag body 1 includes two flat sides, namely the front flat side 1-2 and the rear flat side 1-20; the front flat side 1-2 is arranged on the front side of the bag body 1, and the rear flat side The side 1-20 is arranged on the rear side of the bag body 1; in this embodiment, the bag body 1 also includes four inclined sides 1-3 for forming an "M"-shaped structure; the inclined sides 1-3 They are respectively connected with the front flat side 1-2 and the rear flat side 1-20.

[0025] The front flat side 1-2 and the rear flat side 1-20 are provided with anti-skid structures, which are respectively the first anti-skid structure 1-7 and the second anti-skid structure (not shown in the figure); the first anti-skid structure 1-7 is arranged on the front flat side 1-2; the second anti-skid structure is arranged on the rear flat side 1-20; preferably, the first anti-skid structure 1-7 and the second anti-skid structure are embossed structure or an...

Embodiment 2

[0040] The difference between this embodiment and Embodiment 1 is that the barrier sheet 1-1 is arranged on the inner layer structure 1-9 in the overlapping area; and is adhesively positioned and connected to the two edges of the inner layer structure 1-9.

[0041] Other parts of this embodiment are the same as those of Embodiment 1, so they will not be repeated here.

Embodiment 3

[0043] In this embodiment, the bag body 1 only includes two flat sides, i.e. a front flat side and a rear flat side, such as figure 2 , image 3 As shown; the bag body 1 is surrounded by the front side and the rear flat side; the bag body 1 is provided with an overlapping area; the overlapping area is arranged on the front side.

[0044] The other parts of this embodiment are the same as those of Embodiment 1; therefore, they will not be repeated here.

[0045] The invention realizes exhaust and moisture-proof functions by utilizing the vent hole; the exhaust function of the bag body is enhanced by utilizing the cooperation of the vent hole and the exhaust channel; after the FFS packaging bag is filled and sealed, the internal gas can be quickly Exhaust, improve the exhaust performance of FFS packaging bags, the moisture resistance of the whole package and the drop resistance of the whole package.

Abstract

The invention discloses an air-exhausting and moisture-proof form-fill-seal (FFS) packaging bag which comprises a bag body. The bag body comprises two flat side surfaces; antiskid structures are arranged on the two flat side surfaces; an overlapping region is arranged on the bag body and is arranged on one flat side surface; the overlapping region comprises an inner layer structure and an outer layer structure; and the inner layer structure is arranged on the inner side of the outer layer structure and is connected with the outer layer structure in an adhesion way. The air-exhausting and moisture-proof FFS packaging bag is characterized in that an air-exhausting structure and a barrier plate for air exhausting are arranged in the overlapping region; the air-exhausting structure comprises an air-exhausting channel, a first air-exhausting hole and a second air-exhausting hole; the first air-exhausting hole and the second air-exhausting hole are connected with the air-exhausting channel;and the barrier plate is arranged in the air-exhausting channel of the overlapping area or the inner layer structure of the overlapping area. According to the air-exhausting and moisture-proof FFS packaging bag provided by the invention, after the FFS packaging bag is filled and sealed after being filled, an internal gas can be quickly exhausted, and an air exhaust performance, the moisture resistance and the drop resistance of the FFS packaging bag are improved.

Description

technical field [0001] The invention relates to a packaging bag, in particular to an exhaust and moisture-proof FFS packaging bag, which belongs to the technical field of packaging. Background technique [0002] At present, the high efficiency of FFS (Film bag making-Fill filling-Seal heat sealing integration) filling has made it more and more widely used in chemical, food, construction and other industries, especially in developed countries such as Europe and the United States. Its application ratio is much higher than that of our country. [0003] However, materials filled with FFS generally have high moisture-proof requirements, and the filling time is short, which leads to difficulties in internal exhaust. Especially for powders filled with air, the application of FFS filling has been greatly affected. Restrictions, although the air permeability requirements can be met by punching holes in the bag body, but the strength of the bag body is greatly reduced, the moisture-p...
