Abstract
Fine particle size CaCO.sub.3 is encapsulated with low density polyethylene (LDPE) in a fluid energy mill. Very thin extrusion oriented films (as low as 0.4 mil.) were made using the LDPE encapsulated CaCO.sub.3 at high concentrations of 32-61%. Such films are soft and have a dry 'feel' and translucent appearance with slip and anti-block properties. They can be heat sealed, printed, and folded. The films can be used as paper and paper tissue substitutes.
