THIN FOAMED POLYETHYLENE SHEETS

摘要

The present invention relates to a blown film consisting of one or more foamed polyolefin sheets wherein at least one foamed polyolefin sheet is less than 3 mils thick and has a machine direction (MD) tear strength of at least 50 g/mil, wherein the sheet is made from a blend comprising 10-90 percent by weight linear low density polyethylene (LLDPE) and 90-10 percent low density polyethylene (LDPE) and wherein the LLDPE has a density in the range of 0.900 to 0.930 g/cc and a melt index (MI) in the range of from 2 to 6 g/10 min; wherein the at least one foamed polyolefin sheet has a density reduction of from to 50 percent compared to a non foamed sheet of the same composition.
