ABSTRACT:
A web is formed from two sheets of polymeric material. An upper sheet includes pockets of any form. A lower sheet is subsequently bonded to the upper sheet which causes the sealing of each of the pockets. A web thus formed may be laminated with a metallic foil or metallized polymeric film. Such a web may also be laminated with a similar web in a face to face relationship so that the pockets interdigitate.
