Seal system and method for containers

摘要

A sealable lid assembly and a method of using same to form a tamper evident seal for a container involves a heat shrinkable strip which is preformed on a container lid prior to assembly. The strip includes a first strip of pressure sensitive adhesive tape which is adhered to a lower rim of the container lid, and a second strip of rigid heat shrinkable material adhered to a lower portion of the first strip. The container lid is placed upon a container and heat is then applied to the shrinkable strip, which creates a tamper evident seal between the lid and the container.
