Thermoformed plastic products can be produced by heating a plastic sheet to a pliable forming temperature, shaping it as desirable, and trimming it to create a usable end product. Plastics can be thermoformed through various processes which include vacuum snapback, plug assist forming, and thick and thin gauge thermoforming. Different raw materials used for manufacturing thermoformed plastic products include acrylics, bio-degradable polymers, polycarbonates, acrylonitrile butadiene styrene (ABS), polyethylene (PE), polypropylene (PP), polymethyl methacrylate (PMMA), polystyrene (PS), and poly vinyl chloride (PVC). Thermoformed plastic products are usually lighter in weight and relatively-stronger compared to traditional packaging materials such as glass and woods. Thus, they are most-widely used in different packaging applications in electronic, healthcare, and food packaging industries .
