Best Containers offers a wide variety of flexible round bottom drum liners. We offer 5- to 55-gallon standard round bottom drum liners that conform perfectly to the inside of the drum. These form-fitting, heat-sealed liners do not fold or wrinkle, eliminating trapped product and have fold back liners that pull over the rim of the drum. Our flexible round bottom drum liners are long enough to gather and tie at the top for quick closing and we make them with clear low-density polyethylene and FDA approved resins. We also have round bottom tie-type liners and Polypropylene Hot-Fill liners which you can fill with a product that’s up to 300 degrees. Additionally, we have round bottom CR (chemical-resistant) liners that have a multi-layer nylon-barrier construction that can withstand many chemicals that attack standard polyethylene liners.
