Abstract
Polyethylene films having improved diecutability and compositions for the production thereof comprise from approximately 75% to about 95% of a polyethylene polymer and from about 5% to about 25% of a calcium carbonate filler. Preferably, the calcium carbonate filler comprises polybutylene and solid calcium carbonate having a particle size less than about 3.0 microns. The film produced from the composition is from approximately 1 mil to about 10 mils in thickness. The film can be produced using conventional blown film technology and equipment and has improved diecutability and printability. Thus, the film is readily adaptable to the production of diecut labels.
