Abstract: A laminated web is composed of a paper substrate having a layer of oriented polyethylene terephthalate film bonded to one surface and a layer of polyolefinic resin covering its second surface. The film presents an exposed surface having the known property of being heat sealable to itself, but is not heat sealable to polyolefinic resins.
