    摘要： A process for producing thermoplastic film which is an antifogging, heat-sealable polypropylene film; the antifogging agent is a polyglycerol ester or a sorbitan ester of a fatty acid. The resultant film, which has good clarity, persistent antifogging characteristics, and excellent heat sealability, is useful for packaging refrigerated foods. The disclosure also provides a process for making the film in which the polypropylene-containing thermoplastic resin is extruded into a sheet with subsequent orientation of said sheet in the longitudinal direction to form a monoaxially oriented film; the film is then oriented in the transverse direction.

    摘要： A slip-coated thermoplastic film is disclosed wherein the slip coating applied is essentially an aqueous wax emulsion. The wax emulsion is preferably applied to a thermoplastic film such as polypropylene between the machine direction and transverse direction stretching process. The resultant slip-coated film has low haze, non-blocking, and consistently low coefficient of friction for good machinability.

    摘要： 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 anti-blocking 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.

    摘要： A coating for a thermoplastic film includes an acrylic copolymer, a finely divided wax in the amount of 30 to 150%, preferably 30 to 60%, by weight based on the total weight of the copolymer, a finely divided inorganic solid selected from the group consisting of silica, diatomaceous earth, calcium silicate, bentonite and finely divided clays in the amount of 5 to 25% by weight based on the total weight of the copolymer and either talc or Syloid in the amount of 0 to 1% based on the total weight of the copolymer. The coated film has a low haze, non-blocking and consistently low coefficient of friction for good machinability. The coating is applied to a surface of the film as an aqueous dispersion preferably by a gravure coater placed between the machine direction orienter and the transverse direction orienter in an extruding system for the film. This film can be laminated to another film such as glassine or a plastic film.

    摘要： 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.
