ABSTRACT:
This invention is related to the production and application of heat- shrinkable films derived from a mixture of styrene-butadiene copolymer and polyolefin type resins produced by any of the known processes for polymeric films production. Thermal and mechanical properties of the films derived from this invention makes them suitable to be used, among other applications and with no restriction to the field of this invention, in heat-shrinkable labels, safety seals and overwrap type packaging, blister type thermoformed packaging and in general terms for any kind of packaging, overwrap safety packaging such as the employed to pack audiocassettes, videocassettes, books, magazines, etc., to protect them from tampering, as well as in general applications for packaging material.
