Patent ID: 7235607

Claim:
A heat-shrinkable monolayer film comprising a polymer blend comprising: (a) a polyethylene copolymer having a CDBI of at least 70%, a melt index I 2.16 of from 0.1 to 15 g/10 min., a density of from 0.910 to 0.940 g/cm 3 , a melt index ratio I 21.6 /I 2.16 of from 30 to 80, and an Mw/Mn ratio of from 2.5 to 5.5; and (b) a low density polyethylene (LDPE) having a melt index I 2.16 of from 0.05 to 10 g/10 min and a density of from 0.920 to 0.940 g/cm 3 , wherein the film has a clarity value of at least 10%; and a puncture resistance damaging energy value of at least 140 mJ/μm; a machine direction plastic force of less than 7 cN/15 mm, and a machine direction shrink stress of at least 1.10 mPa.
