Round-bottom bags are the top choice for upgrading the inner lining of metal and plastic drums, completely solving the problems of leakage and cleaning. In the chemical, pharmaceutical, food, and medical industries, metal and plastic drums are widely used as mainstream containers, but they are difficult to clean after each use, time-consuming, and prone to contamination. In recent years, a type of inner lining bag called "round-bottom bags" has become popular. They are directly placed inside the drums and, after use, the bag and its contents can be removed together without cleaning the drum, improving efficiency and avoiding cross-contamination. Currently, they are widely used by most enterprises.
The core advantage of anti static drum liners lies in their vertical round bottom design without any horizontal seals, allowing 100% of the force to be distributed vertically. Even when filled with 50kg or 100kg of materials, they do not experience the common bottom burst issue seen in traditional flat-bottom bags. For flammable and explosive environments, many enterprises specifically purchase anti-static round-bottom bags, with a surface resistance of less than 10⁸Ω, eliminating the risk of static sparks from the source. Disposable bucket liner bags have become the standard for hygiene in food and pharmaceutical enterprises, as they can be directly sealed and discarded after use, meeting GMP and HACCP requirements.
In the field of hazardous and radioactive waste treatment, metal drum inner lining bags are indispensable safety barriers. These inner lining bags are typically made of 8-12 mil thick PE or with an added EVOH barrier layer, capable of withstanding strong acids, strong bases, and high-concentration solvents, and will not leak even after long-term storage. They have become the designated consumables for hazardous waste transportation by environmental protection departments.
Tianbai Plastic Company's metal drum inner lining bags are made of new PE material, with an exclusive round bottom design without horizontal seals, increasing the load-bearing capacity by over 40%. The bag opening can also be equipped with aluminum foil ties or heat-sealed for double insurance, completely solving the problem of material leakage. Anti-static materials can be added to produce anti-static round-bottom bags to meet various needs. What's more, Tianbai Plastic Company provides a full-service chain from sample making, formula adjustment to comprehensive after-sales support, making it an outstanding manufacturer of round-bottom bags in China.
