gasketless pail cover bway tri seal bucketThe BWAY tri-seal, open-head plastic pail cover  produces a watertight/airtight seal without a gasket; 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, with minor adjustments to existing capping equipment. The cover has a primary inner plug “cork” seal; a secondary top flap seal that engages the lip of the pail; and a tertiary outer stretch seal. Available in a variety of shapes and sizes, the 100% high-density polyethylene cover is fully recyclable with the pail.
