CONTAINER COVER MATERIAL

PROBLEM TO BE SOLVED: To obtain a cover material having excellent environmental correspondence and perfume retentivity without using a metal vapor-deposition film by laminating a barrier film having a thin film layer of inorganic substance formed on a base material film and a sealant layer via adhesive by a dry laminating process. SOLUTION: A barrier film 11 formed with a thin film layer 13 of inorganic substance and a sealant layer 14 are laminated on a base material film 12 via an adhesive 15. The film 12 is particularly preferably a biaxially oriented polyethylene terephthalate film, and its thickness is normally 10 to 40μm. The layer 13 is particularly preferably silicon oxide from viewpoints of easiness of a reduction in film thickness, transparency, cost and safety, and its thickness is formed to 500 to 2000 by vacuum evaporation, sputtering or plasma CVD. A print layer 16 is provided on the layer 13 as needed. The layer 14 uses LLDPE, and the adhesive 15 is preferably, for example, polyurethane two- component reaction type adhesive.
