Biaxially oriented polypropylene film |
| abstract |
A thermoplastic film comprising a base layer of a thermoplastic resin which comprises polypropylene and a coating layer of an alkali metal salt of an alkyl sulfate is disclosed. The film is characterized by reduced COF and improved anti-blocking characteristics without the attendant problems associated with decreased clarity, adhesion and wettability common to films treated to improve their COF and anti-blocking characteristics. The disclosure also provides a process for making the film in which the polypropylene-coating thermoplastic resin is extruded into a sheet, said sheet oriented in the longitudinal direction to form a monoxially oriented film, said film coated with the alkali metal salt of an alkyl sulfate and said coated film oriented in the transverse direction. |
