Abstract: A heat-shrinkable film which includes an ethylene-based polymer multilayer or monolayer film and a coating on an outer surface of the ethylene-based polymer film. The ethylene-based polymer film having a single layer or a multilayer structure formed from a first layer, a second layer, and at least one inner layer between the first and second layers. The coating including polyurethane which is the polymerized reaction product of: a polyol; and an aromatic isocyanate functional prepolymer. Further, a method of unitizing polymer wrapped primary packages is provided. The method includes wrapping one or more of the primary packages with the heat-shrinkable film with the coating disposed proximal the one or more primary packages and applying thermal energy to reduce the dimensions of the heat-shrinkable film to constrain the primary package within the heat-shrinkable film. The coating serving to alleviate sticking between the heat-shrinkable film and the polymer wrapped primary package.

Abstract: Embodiments of polyethylene formulations and articles comprising polyethylene formulations are disclosed. The polyethylene formulation may include from 45 wt. % to 90 wt. % of an MDPE having a density of from 0.930 g/cc to 0.950 g/cc and a melt index (I2) from 0.05 g/10 min to 0.5 g/10 min; from 10 wt. % to 50 wt. % of a polyethylene composition having a density from 0.910 g/cc to 0.936 g/cc and a melt index (I2) from 0.7 g/10 min to 1.0 g/10 min; and from 0.5 wt. % to 5% of a masterbatch composition. The polyethylene composition may comprise a first polyethylene fraction area in a temperature range of 45° C. to 87° C. of an elution profile via improved comonomer composition distribution (iCCD) analysis method and a second polyethylene fraction area in a temperature range of 95° C. to 120° C. of an elution profile via iCCD.
