This article describes (1) the applications for heavy-duty sacks, (2) the technical
requirements for the sacks, and (3) the films and resins used to meet the critical
requirements for this industry. It also describes how the technical requirements of
the sack are determined. Finally, it shows how gas phase metallocene-catalyzed
hexene copolymer linear low density polyethylene resins are used to produce
downgauged sacks with tailored properties to meet the needs of this industry.
