Abstract: A two-layer mono-axially oriented film includes a first layer of an opaque beta-nucleated microvoided propylene-based polymer; and a second layer containing a dark pigment that is adapted for use in a thermal printer in which the thermal print-head contacts the exposed surface of the first layer. The dark pigment of the second layer pigment has a color contrasting with the color of the first layer and can contain a carbon black. The first layer includes microvoids and may be made transparent upon the application of heat by collapsing the voids of the first layer or upon the application of ultra-sonic energy.

Optionally, the base layer of a second multilayer PET film with a skin layer inherent viscosity of about 0.70-0.90 and carboxyl endgroup concentration of less than 25 eq/T can be affixed to the opposite side of the metal sheet. The composite is suited for making food and chemical containers such as food storage cans that resist blush discoloration from steam contact during container formation and age degradation during extended storage of harsh chemical products.

Abstract: A carrier film of thermoplastic polyester has releasable metal adhesive properties suitable for a metal transfer in which the polyester film is metalized and the metal layer is subsequently transferred to a permanent adhesive-coated substrate. The metal layer is in direct contact with the polyester carrier film and no intermediate release layer is present. Desired metal adhesion is provided by dispersing an suitable surfactant, and optionally, a hydrocarbon wax, uniformly into the polyester film. Surfactant on the outer surface of the carrier film modifies metal adhesion to the polyester such that the metal can be removed in a metal transfer operation.

Abstract: This invention relates to a highly optically clear, composite film having a predominantly thermoplastic polyester base layer and a primer layer of a polyester and polyurethane blend composition. The base layer preferably has an A/B/C layered structure with a substantially particle-free core layer B of polyester and outer layers A and C of polyester containing nonpolyester, organic and/or inorganic particles. The primer layer is preferably applied to the base layer from solution that is organic solvent-free and is crosslinked using a carbodiimide crosslinking agent. The primer layer and base layer composite can be laminated with a protective layer of primarily acrylic polymer for a solar control film. Various layers of the composite and solar control films can contain effective amounts of functional additives, such as UV light blockers.

Abstract: A metal transfer film of thermoplastic polymer includes a polymeric carrier film, a layer of metal to be transferred onto an article, and a layer of retention adhesive suitable for bonding the transferred metal layer to a surface of the article. The transferable metal layer is adjacent between the carrier film and the retention adhesive layer. Optionally, the carrier film has a releasably adhesive layer on the side in contact with the metal. The retention adhesive is a polyvinyl amine crosslinked with citric acid. The retention adhesive is deposited on the metal layer from a liquid solution and dried to a non-tacky, solid coating enabling handling of the metal transfer film in conventional film processing unit operations. The dry retention adhesive can be activated by the metal transfer operator remotely from the adhesive application process and provides significant oxygen, moisture and aroma barrier properties to the metal covered article.

The multi-layer BOPP film has additional layers such as a third polyolefin resin-containing layer, a metal layer, or combinations thereof.

Abstract: A method reclaims metalized polymer film or mixtures containing metal and/or metal alloys into a metal-containing, polymeric film. The resulting film structure has better oxygen and moisture barrier properties when metalized than plain metalized polymer films. The polymer to be reclaimed, originates in sheet form, and is densified, as by shredding, pelletizing and/or re-extruding into fine particulate form such as chips or pellets. The reclaimed polymeric film can be used, in a range of concentrations, to produce biaxially oriented polyester film for metalizing.
