Abstract
A coextruded multilayer heat shrunk plastic sleeve label having a tough skin layer and a brittle polystyrene foam layer, the skin layer being extruded from a blend of low density polyethylene, a block copolymer of butadiene and styrene as a compatibility agent and optionally, small amounts of polystyrene. The amount of the block copolymer used is sufficient to provide limited adhesion between the skin and foam layers to maximize the toughness of the total label structure. The sleeve label can be sealed by ultrasonic, hot air and heat sealing.
