This invention provides a polymer film coating for use preferably with cold glue labels, particularly on the adhesive-receiving side of a label film. The coating includes a filler component and a binder component, at least one of which is hydrophobic. The coating imparts water resistance and solvent resistance to an adhered label, thereby improving resistance to label removal due to moisture or water contact. A coated label and method of applying the coating to a label film are also included.

Coating or polymeric labels

This invention provides a coated thermoplastic film label comprising a first skin layer comprising a thermoplastic wherein the first skin layer has a first side and a second side, wherein the first skin layer is voided and wherein the first side has an open-cell structure; a core layer comprising a polyolefin, wherein the core layer has a first side and a second side, and the first side of the core layer is adjacent to the second side of the first skin layer; and a second skin layer comprising a polyolefin, wherein the second skin layer has a first side and a second side, the first side of the second skin layer is adjacent to the second side of the core layer, wherein the second side of the second skin layer has a closed-cell structure and wherein the second side is suitable for a surface treatment selected from the group consisting of flame, corona, and plasma treatment; metallization, coating, printing; and combinations thereof, and an inorganic coating on the first side of the first skin layer.

Coating for the adhesive-receiving surface of polymeric labels

The invention relates to a coated film composition comprising:

Coated hope film and its method of manufacture

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.

Process for making coated polypropylene film

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.

Polypropylene film

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.

Low coefficient of friction material and plastic films coated therewith

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.

Biaxially oriented polypropylene film

An oriented heat sealable multilayer film structure having a polyolefin film substrate, a thermoplastic primer coating on the substrate and a heat sealable acrylic or polyvinylidene coating applied to at least one primer coated surface. The primer has a glass transition of from about 0.degree. to about 50.degree. C.

Heat sealable packaging film with drawable primer

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. The resultant slip-coated film has low haze, non-blocking, and consistently low coefficient of friction for good machinability.

Slip coated thermoplastic films

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.
