Abstract

A laminate and a method for forming the laminate. The formation of the laminate may include attaching an inner polyolefin layer (104) and an outer polyolefin layer (106) to a barrier layer (102), wherein the barrier layer (102) is interposed between the outer and inner polyolefin layers. The formation of the laminate may further include forming a holographic film including a backing layer, a release layer (204), an adhesive layer (206), a holographic grating layer (208), a reflective layer (210), and a protective coating (212). The holographic film may be attached to the outer polyolefin layer (106) using a transfer adhesive (300). Subsequently, the backing layer may be removed from the release layer (204), then the release layer (204) may be primed, for example, by forming a primer overcoat layer on the release layer (204). A patterned layer (700), for example, text and/or graphics, may be formed on the primer layer (600), then a varnish layer (702) may be formed on the patterned layer (700).
