Description

Technical Field

[0001] The utility model relates to the technical field of valve bags, and more specifically to a novel valve bag with a baffle. Background Art

[0002] Valve bag is a small bulk packaging container, which is convenient, neat and well sealed. It is one of the most popular packaging materials in the world.

[0003] At present, in order to improve the anti-deformation performance, the valve bag will support the packaging layer. However, during the use of the support, the support stability and support strength are reduced due to the small support area.

[0004] For example, announcement No. CN217457010U discloses a valve bag that is resistant to tearing, including a valve bag body, wherein the valve bag body is provided with an anti-wear layer, a support frame and a packaging layer in sequence from the outside to the inside, and a number of connecting belts are pasted between the anti-wear layer and the packaging layer, horizontal reinforcing rib rings pass through the connecting belts, and vertical reinforcing rib rings are attached to the outside of the horizontal reinforcing rib rings.

[0005] It can be seen from the above-mentioned public scheme that the packaging layers are connected and buffered by connecting belts. Since the connecting belts are soft and easy to deform, their compressive strength is poor after the material is filled, which reduces the support stability and support strength, thereby reducing the anti-deformation performance of the valve bag.

A packaging layer 4 is arranged inside the valve bag body 1, and the packaging layer 4 belongs to the prior art. The outer surface of the packaging layer 4 is in contact with and connected with a baffle 3. There are four baffles 3, which can limit and support the surrounding sides of the packaging layer 4 to prevent the valve bag body 1 from expanding and tearing outward when the material is filled.
