SKIVED FILM FOR COVERING SURFACE OF PLUG FOR MEDICAL PURPOSES, PLUG FOR MEDICAL PURPOSES USING SAID FILM, PRE-FILLED SYRINGE USING SAID PLUG AND METHOD FOR PRODUCING SAID FILM

摘要

Provided is a PTFE skived film capable of exhibiting, with a single layer, sliding properties, barrier properties with regard to a liquid contact surface, and excellent tear resistance during injection molding. This skived film is characterized by being obtained by cutting a polytetrafluoroethylene block or a modified polytetrafluoroethylene block subjected to a thermal fusion treatment under reduced pressure or subjected to a pressurized thermal fusion treatment after being subjected to fusion under reduced pressure.
