Anti-sticking bag for food and drug

Abstract

This utility model discloses an anti-sticking bulk bag for food and pharmaceuticals, belonging to the technical field of anti-sticking bulk bags. The utility model includes an outer bag, an annular airbag, and a micro-textured inner bag arranged from the outer layer to the inner layer. The annular airbag has an air inlet on its side, which is fitted into an air inlet hole on the side of the outer bag. When the annular airbag is filled with gas, the micro-textured inner bag expands inward. This utility model uses a micro-textured inner bag with a diamond / honeycomb pattern, allowing material to contact only the raised points, effectively reducing the contact area by more than 40%, directly weakening molecular forces by half, and improving the anti-sticking effect. Simultaneously, when the annular airbag is filled with gas, the micro-textured inner bag expands inward, further promoting the shedding of material adhering to the inner wall of the micro-textured inner bag and reducing adhesion.

Description

Technical Field

[0001] This utility model relates to the field of anti-stick container bag technology, specifically an anti-stick container bag for food and pharmaceuticals. Background Technology

[0002] FIBCs (Flexible Intermediate Bulk Containers) are widely used in high-end fields such as fine chemicals, food, and pharmaceuticals. However, traditional FIBCs generally suffer from serious "wall adhesion" problems. This directly leads to high unloading residue rates, resulting in waste of high-value materials, cross-contamination between batches, and high cleaning costs, severely restricting the efficiency and economic benefits of enterprises' supply chains.

[0003] Currently, mainstream products still rely on "silicone oil coating + ordinary base fabric" or simple surface coating treatment. These technologies have food safety risks such as short anti-sticking time and easy migration of silicone oil contaminating food and pharmaceuticals, and cannot meet current market demands. To solve these problems, this utility model provides an anti-stick container bag for food and pharmaceuticals. Utility Model Content

It employs a micro-textured inner bag with a diamond / honeycomb pattern, allowing materials to contact only the raised points, thus improving the anti-sticking effect. Simultaneously, when the annular airbag is filled with gas, the micro-textured inner bag expands inward, further promoting the shedding of materials adhering to the inner wall of the micro-textured inner bag and reducing adhesion. This solves the technical problems mentioned in the background art.
