A coextruded multilayer sheet adapted for use as a tough, solvent seal label sleeve on containers, the sheet comprising a foam layer for use on the inside of the sleeve next to the container and an outer decoratable solid skin layer, the skin layer and foam layer being coextruded from an extrudable blend comprising about 30 to 60 wt. % high density polyethylene, about 30 to 50 wt. % of a block copolymer of styrene and butadiene as a compatibility agent, and about 10 to 30 wt. % polystyrene, the resultant sleeve label being tough, and easily solvent sealable on a high speed production basis. The sleeve label can also be sealed by ultrasonic, hot air and heat sealing.

A coextruded multilayer sheet adapted for use as a solvent seal label sleeve on containers in which the sleeve ends are overlapped to form a side seam, the side seam of the sleeve also being sealable by ultrasonic, hot air and heat sealing, the sheet comprising a foam layer for the use on the inside

A coextruded multilayer sheet adapted for use as a solvent seal label sleeve on containers in which the sleeve ends are overlapped to form a side seam, the side seam of the sleeve also being sealable by ultrasonic, hot air and heat sealing, the sheet comprising a foam layer for the use on the inside of the sleeve next to the container and an outer solid skin layer, the skin layer and foam layer being coextruded from an extrudable blend comprising about 35 wt. % up to about 60% of high density polyethylene, about 10 to 30 wt. % polystyrene and about 30 to 50 wt. % of a compatibility agent that is compatible with the polyethylene and the polystyrene to provide limited compatibility and adhesion at the interface of the skin and foam layer, the resultant label being attractive, tough and sealable on a high speed production basis.
