ABSTRACT:
Sealing of elongated packaging laminates of backed antistatic foam around spaced articles being packaged, using edge seals made by first applying heated melting shoes against foam edges of both laminates, then joining the melted foam edges and subjecting the assembly to rollers that press together the joined laminates. Preferably the backing has aluminum layer secured to the foam by pressure-sensitive adhesive. Edge seals can be further subjected to pressure sustained for at least about a second, as while similar pressure is used to apply transverse heat seals to the edge-jointed laminates.
