Abstract
A non-PVC film and film laminate includes a first layer including a polyurethane, a polyurethane-acrylic copolymer, a polyurethane-acrylic blend, and a urethane-acrylic hybrid polymer; and a second layer including a non-polyvinylchloride (non-PVC) based polymer. The film and laminate may be suitable for use in marketing, advertising campaigns, particularly outdoor or other environment impacted promotions, and safety applications. The film and laminate may be transparent, translucent, clear or have other desirable optical properties.

An optically transparent protective film comprising:
- a top layer;
- a bottom layer having a first surface and a second surface, wherein a surface area of the first surface is substantially coextensive and in continuous physical contact with the top layer;
- and
- an adhesive layer in contact with the second surface of the bottom layer, the adhesive layer including a pressure sensitive adhesive;
- wherein the top layer comprises at least 85.56% of a material selected from the group consisting of a polyurethane-acrylic copolymer and a urethane-acrylic hybrid polymer;
- and
- wherein the bottom layer is comprised of a non-polyvinylchloride (non-PVC) based polymer,
- wherein the film (i) passes an accelerated weathering test, (ii) exhibits a gloss at 60 degrees greater than 90, and (iii) exhibits a tensile elongation greater than 200%,
- wherein passing the accelerated weathering test requires that after weathering, the film not exhibit any visible changes after 2,000 hours and ΔE is less than 10.
A transparent film laminate comprising:
- a top layer;
- a bottom layer having a first surface and a second surface, wherein a surface area of the first surface is in continuous physical contact with the top layer;
- an intermediate layer in continuous physical contact with the second surface bottom layer;
- a substrate layer in physical contact with the intermediate layer, and
- wherein the top layer comprises a material selected from the group consisting of a polyurethane-acrylic copolymer and a urethane-acrylic hybrid polymer, and the top layer has a thickness in a range from 0.5 mil (12.7 microns) to 5 mils (127 microns);
- the bottom layer includes a non-PVC based polymer;
- and the substrate layer having printed or image indicia thereon.
An advertising or informational graphic, comprising:
- a surface layer having promotional indicia provided thereon;
- a film including a first layer, a second layer having a first surface and a second surface, wherein a surface area of the first surface is in continuous physical contact with the first layer, and an adhesive layer beneath the second layer on the second surface of the second layer;
- wherein the adhesive layer is in contact with the second surface layer;
- and
- wherein the first layer includes at least 85.56% of a urethane-acrylic hybrid polymer and the second layer includes a non-PVC based polymer,
- wherein the film (i) passes an accelerated weathering test, (ii) exhibits a gloss at 60 degrees greater than 90, and (iii) exhibits a tensile elongation greater than 200%,
- wherein passing the accelerated weathering test requires that after weathering, the film not exhibit any visible changes after 2,000 hours and ΔE is less than 10.
An advertising or informational graphic, comprising:
- a surface;
- an adhesive layer;
- a printable substrate having front and back faces, with the back face facing the surface and in contact with the adhesive layer and the front face having promotional indicia provided thereon;
- a transparent film having a top layer and a bottom layer, with the bottom layer facing the front face of the printable substrate;
- and
- wherein the top layer comprises at least 85.56% of a material selected from the group consisting of a polyurethane-acrylic copolymer and a urethane-acrylic hybrid polymer;
- and
- wherein the bottom layer includes a material selected from the group consisting of a polyurethane-acrylic copolymer, a urethane-acrylic hybrid polymer, a styrene acrylic polymer, and a vinyl acetate ethylene copolymer,
- wherein the film (i) passes an accelerated weathering test, (ii) exhibits a gloss at 60 degrees greater than 90, and (iii) exhibits a tensile elongation greater than 200%,
- wherein passing the accelerated weathering test requires that after weathering, the film not exhibit any visible changes after 2,000 hours and ΔE is less than 10.
A roll or sheet of graphic advertising film, comprising;
- a film having at least first and second layers, the first layer includes at least 85.56% of a urethane-acrylic hybrid polymer and the second layer includes a polyurethane-acrylic copolymer, a urethane-acrylic hybrid polymer, a styrene acrylic polymer, or a vinyl acetate ethylene copolymer;
- and
- one of the first and second layers is provided in operative association with advertising indicia,
- wherein the film (i) passes an accelerated weathering test, (ii) exhibits a gloss at 60 degrees greater than 90, and (iii) exhibits a tensile elongation greater than 200%,
- wherein passing the accelerated weathering test requires that after weathering, the film not exhibit any visible changes after 2,000 hours and ΔE is less than 10.
