Abstract
Coextruded polymeric films having improved machinability and a reduced propensity to release cavitating agent particles during processing and handling of the film are provided. The films are particularly useful as labelstock and especially roll feed labelstock. The films are comprised of multiple coextruded layers, including at least one skin layer cavitated with calcium carbonate and incorporating a silicon gum. The films exhibit improved machinability and while at same time exhibiting a reduced propensity to release a cavitating agent as 'dust' from the cavitated skin layer during film processing and handling.
