Kortec Inc., Ipswich. Mass., last month announced a one-step, coinjection process for producing caps and closures, eliminating the step of applying rubber or aluminum seals to the cap after it’s molded. The process is an extension of Kortec’s technology for producing barrier PET and OPP containers. It combines PP and EVOH in a two-layer structure. Kortec says caps made by the one-step process offer better barrier than conventional two-step closures—and lower cost.
