Abstract
Laminates of two or more low density polyethylene films are prepared by blocking together superimposed films at a temperature below the fusion temperature, whereby the films can be pealed apart without distortion. The laminates are adapted for the manufacture of heavy duty bags and sacks having increased impact and tear resistance, as compared with single films or fused together laminates having the same gauge.
