Material selection and optimization
Choosing the right material is the basis for improving the sealing performance of the container bag. Materials with good flexibility, strength and corrosion resistance should be selected, such as high-strength polypropylene. At the same time, the material can be modified and some special additives can be added to enhance its sealing performance. For example, adding an anti-aging agent can improve the material's anti-aging ability and prevent the material from being poorly sealed due to the degradation of material performance due to long-term use; adding a plasticizer can improve the flexibility of the material, so that it can fit better in different environments, reduce gaps, and effectively prevent material leakage.
Improving the stitching process
The stitching process is crucial to the sealing performance of the container bag. Using fine and firm stitching methods, such as double-thread chain stitching or three-thread overlocking, can enhance the sealing of the bag. During the stitching process, ensure that the tension of the stitches is uniform to avoid problems such as skipping and leaking stitches. In addition, the stitches can also be specially treated, such as applying sealant or using heat sealing technology to seal the stitches to further fill the gaps and prevent the material from leaking from the stitches. This can greatly improve the sealing reliability of the container bag during transportation and storage, and reduce the risk of leakage caused by stitching problems.
Design a reasonable bag opening structure
The bag opening design of the container bag directly affects its sealing effect. Common bag opening structures include open, tied and valve bags. For materials that require better sealing performance, valve bags are a good choice. Valve bags are loaded and unloaded through special valve devices. After loading, the valve can automatically close and seal to effectively prevent material leakage. At the same time, the size and shape of the bag opening should also be reasonably designed according to the characteristics of the material and the loading and unloading method to ensure that the bag opening can be tightly closed after being filled with materials, and it is not easy to open due to external forces during transportation, so as to ensure that the material is always in a sealed state.
Strengthen quality inspection and maintenance
In order to ensure the sealing performance of the container bag, strict quality inspection and regular maintenance are essential. During the production process, the container bag should be fully inspected for sealing, such as using air pressure test or water pressure test to check whether there are leaks in the bag body. For products that fail the inspection, they should be repaired or scrapped in time. During use, the Container bag should be inspected and maintained regularly to promptly detect and deal with problems with reduced sealing performance due to wear and aging. In addition, during loading, unloading and transportation, care should be taken to avoid unnecessary damage to the Container bag, extend its service life, ensure that it always maintains good sealing performance and prevent material leakage.
