ABSTRACT:
A packaging material for photosensitive materials which comprises an uniaxially molecularly oriented thermoplastic resin film layer, an ethylene copolymer resin film layer containing more than 10 wt. % of ethylene copolymer resin, a substance having antiblocking action and an antioxidant and having a melting point of lower than said uniaxially molecularly oriented thermoplastic resin film layer, and a metallized biaxially molecularly oriented thermoplastic resin film layer interposed between said uniaxially molecularly oriented thermoplastic resin film layer and said ethylene copolymer resin film layer.
The packaging material of the invention hardly curls, and it is excellent in tear strength and heat sealing properties. Moreover, when the package is severely shaken during transportation, moistureproofness and lint-free ability can be still secured.
