U.S. Pat. No. 4,778,058 provides a pouch from a film of two plastic layers. A discreet area of the first layer, corresponding to a folded portion of the resultant pouch, is surface roughened prior to lamination to the second layer. The irregularities from roughening are filled with the plastic material of the second plastic layer. The film of the two layered film is heat-sealed into a pouch. The surface roughening is at a position on the first layer of the film other than the portion thereof to be heat sealed. While U.S. Pat.
