Abstract:
Thermoformed articles include cycloolefin/ethylene copolymer and LLDPE. The articles are formed with an areal draw ratio of 1.5 and greater and exhibit unexpectedly elevated stiffness along with ductility suitable for forming deep-draw parts. Multilayer sheet is used for achieving a desired set of properties.
