发明名称 A PROCESS FOR LOW TEMPERATURE HEAT SEALING OF POLYETHYLENE
摘要 A process of producing a heat sealed extrusion coated polyethylene article is disclosed. This process entails heat sealing, at a temperature below 95.degree.C, two opposing extrusion coated polyethylene laminate surf aces thereby welding the surfaces to effect a heat seal. The polyethylene has a narrow molecular weight distribution, a low melt index, a low swell ratio, and a polydispersity index below 5.
