The invention is directed towards a method for improving hot tack in blown polyethylene films. Accordingly, a nucleating agent and polyethylene are combined to form a melt from which the film is blown. The method comprises forming a melt of polyethylene and a nucleating agent selected from the group consisting of dibenzylidene sorbitol, paramethyldibenzylidene sorbitol, dimethyldibenzylidene sorbitol, ethylene copolymers containing grafted maleic anhydride, ethylene copolymers containing grafted acrylic acid, and mixtures thereof. Polyethylene films having increased hot tack can be blown therefrom. |
