POLYPROPYLENE FILM AND PROCESS FOR MAKING SAME |
摘要 |
<p>A thermoplastic film structure comprising a base layer of a thermoplastic resin which comprises polypropylene and a coating layer of a polyvinylidene fluoride is disclosed. The film is characterized by reduced coefficient of friction, improved antiblocking characteristics, and enhanced oxygen and water vapor barrier properties. The disclosure also provides a process for making the film in which the polypropylene-containing thermoplastic resin is extruded into a sheet, said sheet oriented in the longitudinal direction to form a monoaxially oriented film, said film coated with the polyvinylidene fluoride and said coated film oriented in the transverse direction.</p> |
