More Information
Summary:A multilayer film comprises at least 3 layers including a first outer layer, a second outer layer and between the first and second outer layers at least one core layer. The first and second outer layers each comprise at least 75 weight percent of (a) at least one high impact polystyrene component. The core layer(s) comprises(s) (b) at least one styrene block copolymer that is present at a concentration of at least about 2 weight percent of the polymers in the film; and polymers (a), (b) and (c) at least one general purpose polystyrene having a Mw of more than 200,000 and 350,000 or less and that is present at a concentration of at least about 10 wt. % and up to at most about 50 wt. % of the polymers in the composition account for 100 percent by weight of the polymers in the polymer composition excluding polymeric additives.
