a shrink film having high optical clarity , good shrink properties , and good mechanical properties is obtained by stretching biaxially , without prior crosslinking , a film made of a copolymer of ethylene with at least one c 8 - c 18 α - olefin , which copolymer has two distinct crystallite melting points below 128 ° c ., the difference between these melting points being at least 10 ° c ., and stretching being carried at a temperature within the range defined by these melting points . the above copolymer may be blended with a homopolymer of an α - olefin or copolymer with another α - olefin or another ethylenically unsaturated comonomer , which may constitute up to about 95 weight % of the blend . the shrink film of this invention is particularly suitable for wrapping consumer goods which have to maintain good sales appeal .
