ABSTRACT:
A method is disclosed for improving the clarity of polyethylene film containing silica or diatomaceous earth as an anti-blocking agent. The method comprises treating the anti-blocking agent with polyethylene glycol such that sufficient polyethylene glycol is deposited on said anti-blocking agents so that the weight ratio of said polyethylene glycol to said anti-blocking agent is at least about 1:30. Next, the treated anti-blocking agent is added to the polyethylene resin and this blend is formed into a film.
