ABSTRACT:
A method of packaging a product by heat shrinking a low gauge, low shrink force, polyester shrink film to a rigid container. The lidding film engages around the outside of the container, thereby protecting the contents and providing evidence of tampering. The packaged product can be heated and will generally vent steam, while maintaining tamper resistance.
