PURPOSE: To interrupt strong odor and to improve preservation and storage by laminating an inner face layer in contact with medical product containing creosote with ethylene-acrylic copolymer.

CONSTITUTION: An inner face layer in contact with medical product containing creosote is laminated with ethylene-acrylic copolymer. The copolymer which contains 30wt.% or less, preferably 3W20wt.% and more preferably 10W15wt.% of acrylic acid is employed. For the laminating known methods, such as an extrusion laminating method, a coating method or a film bonding method, etc., is applied. The thickness of the copolymer film of the laminated film is 5μm or more, preferably 10μm or more and more preferably 20μm or more, and the thickness of the aluminum foil is 20W70μm or preferably 30W50μm.
