<p>The stretchable plastic film comprises a substrate including a middle layer (50-60 wt.%) between two outer layers (20-25 wt.%). The middle layer is composed of 50% of ethylene vinyl acetate, and has a stress of less than 85 daN/cm 2>in a cross direction. The two outer layers are composed of 95% of metallocene polymer and 5% of additive.</p> |
