The Tri-Seal gasketless openhead plastic pail cover from BWAY Corp. produces a watertight/airtight seal without a gasket. Ideal for foods products, it can be used anywhere a typical gasketed cover is used. No special capping equipment is needed. The cover works with standard rigid-plastic pails and is a drop-in replacement for a standard gasketed cover on most filling lines. It is also environmentally friendly.
