ABSTRACT:
A sealed composite container for products is provided having a paperboard body ply with a liner ply adhered on the inner surface thereof. One end of the container is rolled outwardly to form a rim and exposing the inner surface of the liner ply, which comprises a heat sealable composition. A lid for the container, also having a layer of heat sealable composition, is placed adjacent to the exposed heat sealable composition of the container liner and heat sealed thereto. The heat seal has both an inner and an outer bead formed on either side of the heat sealed area, wherein the inner bead comprises a larger amount of the heat seal compositions than the outer bead. A method and apparatus for forming the heat seal is also provided.
