ABSTRACT:
Improved sheets of bonded plexifilamentary film-fibril strands spun from a polyolefin and a pigment are provided. The polyolefin comprises at least 90% by weight of the fibril strands, and the pigment comprises between 0.05% and 10% by weight of the fibril strands. The sheet has a high opacity and high smoothness, even when the sheet is bonded to a delamination strength greater than 120 N/m or when subjected to calendering. The sheet material is highly printable.
