Vacuum forming process, has been known as early as in the beginning of the 20th century, but applied to industrial production after only 40 years of the 20th century, have a large development in the 1960s. In the past 20 years, PS blister it has developed into one of the most important methods of processing and packaging materials.

The reason for the rapid development of this technology is the vacuum forming process innovation and equipment, as well as the development of new sheet molding performance; blister packaging products itself but also by the development of the packaging industry and vacuum plastic molding characteristics decision.

         Plastic production efficiency, saving raw and auxiliary materials, light weight, easy to transport, good sealing performance, environmentally friendly green packaging requirements; packaging of any profiled products, the packing without additional cushioning material; visible transparent packaging products shape beautiful, easy to sell, and suitable for mechanization, automation, packaging, ease of modern management, save manpower and improve efficiency. Blister equipment relative to other plastic molding plus process in terms of investment. Mold making, plaster mold, copper mold, aluminum mold, resin mold.
