November 1965 saw the purchase of Beco Products by MSL Industries. Beco Products would continue to sell products partially under their name, often as Beco Products, a subsidiary of MSL Industries. By the summer of 1968, the Beco Products name was discontinued in favor of MSL Plastics. The once Beco Products molds would later be acquired and manufactured by General Foam Plastics in early 1970, marking the end of MSL Plastics.
Blow-Molded’s use of the name Beco Products refers to both the independent and post-acquisition company; until their MSL Plastics rename.
