TITLE Stretched-and-Bonded Plexifilamentary Sheet ABSTRACT OF THE DISCLOSURE Lightweight nonwoven sheets of polyethylene plexifilamentary film-fibril strands are made by a stretching-and-bonding operation in which the unit weight of the sheet is decreased in stage while at a temperature within 3 to 8°C of the melting point of the polyethylene. The resultant sheet has a novel combination of opacity, X-ray scattering and physical characteristics and is particularly suited for sterile packaging, lightweight envelopes and surgical drapes.
