ABSTRACT:
A cushioned bag has two adjacent multilayered sections comprising an outer layer of flexible thermoplastic material, a middle layer (or partial middle layer) of polyolefin film, and an inner layer of cushioning material. The sections are fused together along at least one edge of the bag to form a seamed edge comprising a fused bead. Apparatus for making a bag having a beaded edge includes cooperating heated jaws between which the bead is formed. A method of using the apparatus to make the bag includes rotating take-up rolls faster than feed rolls to pull the bag cleanly away from the jaws along the bead forming the seamed edge.
