    Abstract: PURPOSE: To provide a sealable multilayered plastic film which has excellent peelability and toughness. CONSTITUTION: This multilayered film comprising an uppermost layer A which has a melting point over 200 deg.C and dimensional stability at elevated temperatures, an adhesion promoter B consisting of a styrene/butadiene block copolymer of 30 to 95% by weight, a polystyrene and/or a high-impact polystyrene of up to 95% by weight, and a polymer which is incompatible with polystyrene and has polar groups of 5 to 70% by weight, a styrene/butadiene block copolymer C of 5 to 100% by weight and a polystyrene and/or a high-impact polystyrene of up to 95% by weight, a barrier layer D equivalent to the uppermost layer, and a sealing layer E corresponding to the adhesion promoter B.
