Material Notes:
LL 1820 is an ethylene-butene copolymer produced in a gas phase reactor. It is designed for delivering competitive performance in most blown film applications.LL 1820 can be processed at high output rates with moderate extrusion pressure, good bubble stability and gauge control on blown film machine designed for LLDPE.LL 1820 can advantageously be blended with LDPE or other PE resins used in blown film mono extrusion or coextrusion to improve film properties.LL 1820 is suited for many applications in the field of consumer, industrial, food or hygiene packaging such as collation shrink, liners, Form-Fill-Seal, heavy-duty sacks, refuse sacks or other bags and non-packaging applications like agriculture films e.g. tunnel and mulching films.Contains antioxidant.Information provided by Total Petrochemicals.
