Olefin polymers having a melt strength of about 5cN at 190 ° C., and when made into a film have a CD shrink of at least 20%. Some of the polymers have a comb-like structure with at least 0.3 long-chain branches per 1000 carbon atoms are disclosed. Some compositions described herein include a high molecular weight fraction and a low molecular weight fraction wherein the ratio of the molecular weight of the high molecular weight fraction to the molecular weight of the low molecular weight fraction is greater than about 1.3. |
