Flexibility for Shrink Film Capabilities

Editor's Note: The following is an excerpt from a presentation made at the K 2010 trade show in June by Dr. Daniel Wagner, BASF's product development–SBC polymers.

Launched onto the market three years ago, shrink films based on Styrolux® HS 70 have become well-established in the European sleeve market. Compared to conventional mixtures of SBC (styrene butadiene block copolymer) and PS (polystyrene), this material stands out for its very high final shrinkage of more than 70 percent.
