Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to an FFS heavy packaging bag. Background Art

[0002] At present, heavy-duty packaging bags mainly include plastic woven bags, multi-layer paper bags, and co-extruded PE film heavy-duty packaging bags. Co-extruded PE film heavy-duty packaging bags can be used in the form of film rolls for fully automatic form-fill-seal packaging systems to form heavy-duty packaging bags, also known as FFS bags. Although plastic woven bags and multi-layer paper bags are mostly used as heavy-duty packaging bags in China, FFS bags are gaining more and more attention due to their high sealing performance and high packaging efficiency, and have been widely used in the field of industrial raw materials such as plastic granular raw materials. However, the current FFS heavy-duty packaging bags are generally sealed by heating and plastic sealing. When the product is subsequently taken out of the bag, it can only be opened by destroying the bag, and it cannot be recycled again, resulting in a waste of resources. Utility Model Content

In the following description, it should be understood that the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "longitudinal", "horizontal", "vertical", "horizontal", "top", "bottom", "inside", "outside", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings, are constructed and operated in a specific direction, and are only for the convenience of describing the present technical solution, rather than indicating that the device or element referred to must have a specific direction, and therefore cannot be understood as a limitation to the present invention.

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] Please combine Figure 1 and Figure 2 The embodiment of the present disclosure provides an FFS heavy packaging bag, including a packaging bag body 10, a sealing strip and an anti-slip part 30.

[0027] Specifically, the packaging bag body 10 is formed by the first bag surface 11 and the second bag surface 12 which are arranged oppositely, and a bag opening which is connected to the inside of the packaging bag body 10 is formed on one side of the first bag surface 11 and the second bag surface 12. The sealing strip includes a first sealing bone strip 20 and a second sealing bone strip 60 which are arranged oppositely, the first sealing bone strip 20 is arranged on the surface of the first bag surface 11 facing the second bag surface 12, and a concave bone is arranged on the inner side surface of the first sealing bone strip 20, and a convex point with elasticity is arranged on the inner wall of the concave bone, and the second sealing bone strip 60 is arranged on the surface of the second bag surface 12 facing the first bag surface 11. The anti-slip member 30 is arranged on the surface of the first bag surface 11 away from the second bag surface 12, and a convex bone which matches the concave bone is arranged on the inner side surface of the second sealing bone strip; when the convex bone is inserted into the concave bone, the convex point abuts against the surface of the convex bone. When the bag opening is pulled along the first direction, the first sealing bone strip 20 and the second sealing bone strip 60 are buckled or released from each other to seal or open the bag opening.

[0028] Here, it should be noted that the “first direction” mentioned above refers to the setting direction of the first sealing bone strip 20 or the second sealing bone strip 60. Figure 1 The first sealing bone strip 20 is along the width direction of the packaging bag body 10 ( Figure 1 If the first direction is set as the x direction in the figure, the first direction refers to the width direction of the packaging bag body 10.

[0029] For example, the first sealing bone strip 20 and the second sealing bone strip 60 mainly play the role of sealing the bag opening, and they can be seals that can be mutually buckled in the prior art, and this is not limited. In addition, it should be noted that the above-mentioned "pulling the bag along the first direction X" refers to manually squeezing the first sealing bone strip 20 and the second sealing bone strip 60 along the first direction X, so that the first sealing bone strip 20 and the second sealing bone strip 60 are close to each other and buckled, thereby sealing the bag opening.

[0030] For example, after the product is packed in a packaging bag, the packaging bags containing the product need to be stacked and placed on a transport vehicle for transportation. However, since the outer surface of the packaging bag is relatively smooth, relative sliding is likely to occur during the stacking process, causing the stacked packaging bags to slide and cause damage to the packaging bags. To this end, in this embodiment, an anti-slip member 30 is provided on the surface of the first bag surface 11 away from the second bag surface 12, so that the friction between the stacked heavy packaging bags can be increased, which can effectively prevent the heavy packaging bags from sliding during use.

[0031] For example, during the process of squeezing the first sealing bone strip 20 and the second sealing bone strip 60, the first sealing bone strip 20 and the second sealing bone strip 60 are close to each other, so that the concave bone 80 on the first sealing bone strip 20 and the convex bone 90 on the second sealing bone strip 60 are buckled, thereby sealing the bag opening, which has a simple structure and is easy to operate. If the bag opening needs to be opened, it is only necessary to pull the first sealing bone strip 20 and the second sealing bone strip 60 away from each other, so that the concave bone on the first sealing bone strip 20 and the convex bone on the second sealing bone strip 60 are released from buckling, thereby opening the bag opening.

[0032] During transportation, the convex bone 90 on the second sealing bone strip 60 may be separated from the concave bone 80 of the first sealing bone strip 20 due to road bumps and other problems, causing the bag opening to open, affecting the sealing effect. To this end, in this embodiment, by providing elastic convex points 100 on the inner side of the concave bone 80, when the convex bone 90 is inserted into the concave bone 80, the convex points 100 will abut against the surface of the convex bone 90 to provide a certain pressure on the convex bone 90, so that the convex bone 90 is not easily separated from the concave bone 80, which can avoid the problem of the bag opening being easily opened during transportation.

[0033] The FFS heavy-duty packaging bag based on the above technical features is formed by surrounding a packaging bag body 10 with a first bag surface 11 and a second bag surface 12, and respectively arranging a first sealing bone strip 20 and a second sealing bone strip 60 on the first bag surface 11 and the second bag surface 12, and then the first sealing bone strip 20 and the second sealing bone strip 60 are mutually engaged by squeezing each other to achieve sealing of the bag opening; when the product needs to be taken out from the inside of the packaging bag body 10, it is only necessary to pull the first sealing bone strip 20 and the second sealing bone strip 60 away from each other to release the buckle of the first sealing bone strip 20 and the second sealing bone strip 60, thereby opening the bag opening and taking out the product. The structure is simple, and compared with the traditional sealing method of using heat and plastic sealing, it can avoid structural damage to the packaging bag body 10 during the process of taking out the product, and can be recycled for multiple times, which is beneficial to reducing production costs and avoiding pollution to the environment.

[0034] In other embodiments, the inner side surface of the first sealing bone strip 20 is provided with a convex bone, and correspondingly, the inner side surface of the second sealing bone strip 60 is provided with a concave bone matching with the convex bone.

[0035] In order to facilitate pulling apart the first sealing bone strip 20 and the second sealing bone strip 60, in one embodiment, the first sealing bone strip 20 and the second sealing bone strip 60 are arranged at a distance of 2 cm to 4 cm from the bag opening, so that the operator has enough grip to pull the first sealing bone strip 20 and the second sealing bone strip 60 outward.

[0036] In one embodiment, the anti-slip member 30 includes a first anti-slip strip 31 and a second anti-slip strip 32, and the first anti-slip strip 31 and the second anti-slip strip 32 are respectively arranged along a first direction X and a second direction Y. Among them, the first direction X intersects the second direction Y.

[0037] Exemplarily, an included angle is formed when the first direction X and the second direction Y intersect, and the angle range of the included angle is between 0° < a ≤ 90°. In this embodiment, preferably, the first direction X is perpendicular to the second direction Y.

[0038] Exemplarily, by arranging the first anti-slip strip 31 and the second anti-slip strip 32 along the first direction X and the second direction Y respectively on the surface of the first bag surface 11 facing away from the second bag surface 12, the anti-slip member 30 has better stability, and can increase the contact surface, which is beneficial to increasing the friction force between the stacked heavy packaging bags, and can effectively prevent the heavy packaging bags from slipping during use.

[0039] In one embodiment, the width of the first anti-slip strip 31 is the same as the width of the second anti-slip strip 32. Among them, the width of the first anti-slip strip 31 is between 3 cm and 5 cm.

[0040] Please refer to Figure 3 , in one embodiment, a plurality of anti-slip points 70 are distributed on the surfaces of the first anti-slip strip 31 and the second anti-slip strip 32 facing away from the first bag surface 11 and are arranged in an array along the first direction and the second direction. In this way, the friction coefficient can be improved and the friction force between the stacked packaging bags can be increased.

[0041] Specifically, the anti-slip points 70 cover the surface of the first anti-slip strip 31 or the second anti-slip strip 32, and the distance between adjacent anti-slip points 70 is between 3 mm and 5 mm. Exemplarily, the surfaces of the first anti-slip strip 31 and the second anti-slip strip 32 are completely covered by the anti-slip points 70, so as to further increase the friction force between the packaging bags and avoid falling during the stacking process.

[0042] In one embodiment, a first sealing portion 40 extends from one end of the first bag surface 11 extending towards the bag opening, and a second sealing portion 50 extends from one end of the second bag surface 12 extending towards the bag opening. The first sealing portion 40 and the second sealing portion 50 are adhesively bonded to each other by heat sealing to seal the bag opening.

[0043] Exemplarily, by fitting the first sealing portion 40 and the second sealing portion 50 together and using the heat sealing technology in the prior art to adhesively bond the first sealing portion 40 and the second sealing portion to each other, the bag opening can be further sealed to avoid problems such as insecure sealing or false sealing.

[0044] In one embodiment, the first bag surface 11 and the second bag surface 12 are made of a material selected from the group consisting of polyethylene, polypropylene, and composite films.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
