To make scratches, cracks, blobs, etc., obscure and to make appearance extremely beautiful by subjecting the counter-heat seal layer surface side of a metallic layer of a packaging material including the metallic layer to printing.

The counter-heat seal layer surface side of the metallic layer of the packaging material including the metallic layer is subjected to printing. The metallic layer is ≥ kind selected from metallic foil (aluminum foil, iron foil, copper foil, stainless steel foil, lead foil, tin foil, etc.), and metallic thin film processing layer (aluminum, tin, chromium, etc.), of metal thin film processing flexible sheets. The thickness of the metallic foil is 5 to 70 μm, more preferably 6 to 50 μm, more particularly preferably 7 to 30 μm. The thickness of the metallic thin film processing layer is 50 to 1500 , more preferably 100 to 800 , more particularly preferably 200 to 600 . The light arriving at the metallic may be weakened, the reflected light may be weakened as well and the rubbing flaws, etc., may be made obscure by printing.
