The flexible, multilayer film has at least a first polymeric layer, indicia, a layer of release coating that is applied in a pattern to a portion of an interior surface of the first layer and a second polymeric layer which may be made in combination with additional layers. A removable portion of the film structure is provided by a pattern of perforations or slits through certain layers of film in alignment with the release coating pattern. The method of manufacturing the multilayer film with an integrated coupon includes providing a first polymeric layer as an outer layer, printing indicia, applying a layer of release coating in a pattern to a portion of an interior surface of the first layer, cutting slits through certain layers and laminating a second polymeric layer. ## Claims ### Claim 1 A multilayer film with a peelable coupon comprising: an outer polymeric, thermoplastic layer wherein the outer layer comprises an innermost surface of a packaging unit, indicia surface printed on an interior surface of the outer layer, a layer of release coating in a pattern on a portion of the interior surface of the outer layer having the indicia, the peelable coupon formed by slits through the outer layer and the indicia and into the layer of release coating, wherein the slits are in alignment with the pattern of the layer of release coating, and a second polymeric layer bonded to the outer layer. ### Claim 2 (depends on 1) The film of claim 1 wherein the release coating is a silicone, a release varnish, a release lacquer or any other release agent. ### Claim 3 (depends on 1) The film of claim 1 wherein the outer layer is a polyethylene or an oriented polypropylene. ### Claim 4 (depends on 1) The film of claim 1 wherein the second polymeric layer is an extrudate of polyethylene or an oriented polypropylene adhesive laminated to the outer layer. ### Claim 5 (depends on 1) The film of claim 1 further comprising printing on an exterior surface of a portion of the outer layer encompassing the peelable coupon. ### Claim 6 (depends on 1) The film of claim 1 further comprising an additional layer. ### Claim 7 (depends on 6) The film of claim 6 wherein the additional layer is continuous to maintain barrier integrity. ### Claim 8 (depends on 7) The film of claim 7 wherein the additional layer is metallized oriented polypropylene. ### Claim 9 (depends on 1) The film of claim 1 wherein the second polymeric layer has a different appearance from an exterior surface of the outer layer so the removal of the peelable coupon is apparent. ### Claim 10 A multilayer film with an integrated removable banner suitable for forming a packaging unit, the film forming a web with repeating units, each repeating unit of the web comprising: an outer polymeric, thermoplastic layer wherein the outer layer comprises an innermost surface of the packaging unit, indicia surface printed on an interior surface of the outer layer, a layer of release coating in a stripe on a portion of the interior surface of the outer layer having the indicia, and a second polymeric layer bonded to the outer layer, wherein the integrated removable banner is formed by slits through the outer layer and the indicia and into the layer of release coating, wherein the slits extend across an entire surface of the repeating unit and the slits are parallel to edges of the stripe of the layer of release coating. ### Claim 11 (depends on 10) The film of claim 10 wherein each repeating unit has different indicia on each portion of the interior surface of the outer layer that is between the slits. ### Claim 12 (depends on 10) The film of claim 10 wherein the release coating is a silicone, a release varnish, a release lacquer or any other release agent. ### Claim 13 (depends on 10) The film of claim 10 wherein the outer layer is a polyethylene or an oriented polypropylene. ### Claim 14 (depends on 10) The film of claim 10 wherein the second polymeric layer is an extrudate of polyethylene or an oriented polypropylene adhesive laminated to the outer layer. ### Claim 15 (depends on 10) The film of claim 10 further comprising printing on an exterior surface of a portion of the outer layer encompassing the integrated removable banner. ### Claim 16 (depends on 10) The film of claim 10 further comprising an additional layer. ### Claim 17 (depends on 16) The film of claim 16 wherein the additional layer is continuous to maintain barrier integrity. ### Claim 18 (depends on 17) The film of claim 17 wherein the additional layer is metallized oriented polypropylene. ### Claim 19 (depends on 10) The film of claim 10 wherein the second polymeric layer has a different appearance from an exterior surface of the outer layer so it is apparent when the integrated removable banner has been removed.
