摘要:
A web of polymeric foam which is sealed on one or both sides by a thin, hard plastic layer is disclosed. The sealed web is prepared by coating an auxiliary substrate with a film of hard plastic-forming resin, laminating this film to a polymeric foam web by means of a curable adhesive applied to the hard plastic, and removing the auxiliary substrate.
