摘要 |
<p>There is disclosed a flexible co-extruded three layer film comprising outer layers of high pressure, low density polyethylene and a core layer of low pressure, low density polyethylene. The film is produced by a blown film tubular extrusion process at conventional rates and temperature and yet is free of melt fracture even though the low pressure, low density polyethylene would otherwise exhibit melt fracture.</p> |
