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.
