ABSTRACT:
A sealing and severing apparatus is disclosed for sealing plastic bags formed in succession from stock plastic film material and then severing the sealed bags from one another. The bags are filled with a foamable composition while they are being formed so that when the formed and filled bags are placed in a container, the foamable composition fills the bag with foam to thereby produce a customized foam cushion for any objects in the container.
