Polyvinyl alcohol (PVAL) is a plastic material little known so far. It offers the outstanding attribute of solubility in water with simultaneous high resistance to most contact chemicals. PVAL has been little known until recently, primarily because it could only be processed into film, but manufacturing injection-molded parts from it was not possible. The reason was its large variation in characteristic material values due to batch production. This changed, however, with the solutions discovered by the Austro-Polish injection molding company Buzek Plastic, which developed over a period of 10 years and in several evolutionary steps a mass production technology for making water-soluble, multi-chamber laundry detergent containers, of which it has been producing more than 1.3 billion units per year. The machinery and automation technology for this purpose have been supplied by WITTMANN BATTENFELD.
“After we had communicated our wishes and ideas to several machine manufacturers, we finally found again the right partners in the WITTMANN team, which is open for innovation...”
