Abstract
A thermoformable sheet includes an exterior film, a printed pigment layer, an adhesive layer, an inner layer, and an interior sealing layer. The exterior film includes between 50% and 100% polyolefin-based polymers, by weight. The inner layer includes between 60% and 100% of high-density polyethylene polymer, by weight. The inner layer further includes a thickness between 100 microns and 350 microns. The printed pigment layer and the adhesive layer are located between the exterior film and the inner layer.
