Abstract: Recyclable films having a first layer containing a polyethylene, a second layer containing a high-density polyethylene and a hydrocarbon resin, and a third layer containing a polyethylene may be used for thermoforming packaging components. Both the first and third layers have an overall density between about 0.92 g/cm3 and 0.97 g/cm3. The film structure is advantageous as it can be more easily thermoformed than traditional high-density polyethylene films and can maintain the shape taken during thermoforming, exhibiting minimal warping or shrinking.
