ABSTRACT:
Stock material comprises a plastic substrate having a thickness in the range of about 0.001 to 0.010 inch and melt temperature above about 275.degree. F., and an adhesive layer carried by the substrate and having a thickness in the range of about 0.001 to 0.006 inch and a melt temperature below about 225.degree. F. The adhesive layer has an exposed, textured surface defining a multiplicity of elongated channels. The stock material is used for working a plastic pouch to laminate a photograph or other document. A top flap is joined to a bottom flap so as to lie congruently thereon and form a pocket for receiving a photograph on the bottom flap and beneath the top flap. The bottom and top flaps each have a substrate side external to the pocket and an adhesive side defining the pocket. The adhesive side of at least the top flap, has a textured surface defining a multiplicity of channels. A carrier for use in laminating a document within a plastic pouch, comprises a bottom flap of release material for receiving the pouch with document and a top flap of release material foldable over the bottom flap. Fixture structure, such as a cut-out, projects from at least one of the flaps, for contacting and applying enhanced pressure to the pouch at the edges of the document.
