Abstract
A blend comprising polyolefin and hydrocarbon resin, wherein the polyolefin is semicrystalline and has a suitable degree of crystallinity and molecular weight, or the polyolefin is amorphous and has sufficiently high molecular weight, and sufficient hydrocarbon resin is present in the blend, so that a film made from the blend is substantially vinyl-like and non-elastomeric. Some of the films are also conformable, drapable or affinely deformable by hand.
