摘要： Recyclable films having at least a first layer containing a high-density polyethylene and a nucleating agent, a second layer containing a high-density polyethylene and a third layer containing a high-density polyethylene and a nucleating agent may be used for thermoforming packaging components. The film structure is advantageous as it can be more easily thermoformed that traditional high-density polyethylene films and can maintain the shape taken during thermoforming, exhibiting minimal warping or shrinking.

摘要： Recyclable films having at least a first layer containing a high-density polyethylene, a second layer containing a high-density polyethylene and a hydrocarbon resin, and a third layer containing a high-density polyethylene may be used for thermoforming packaging components. 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.
