In-house coinjection molding for GE Plastic

“A number of health-care packaging trends, including demand for better clarity and greater emphasis on patient and caregiver safety, have highlighted the drawbacks in monolayer packaging made from glass and plastic,” says John Davis, technical manager, Healthcare, GE Plastics, Pittsfield Mass.

“To help customers in the in-vitro diagnostic (IVD) and pharmaceutical industries address these limitations and meet changing market needs, we have added coinjection blow-molding at our Polymer Processing Development Center.” Coinjection blow-molding lets crystal- clear, virtually unbreakable Lexan HP polycarbonate (PC) resins sandwich around an interior layer. The laminated construction is a candidate for pharmaceutical and IVD packaging, including diagnostic vials, culture vials, and drug containers.

Coinjected resins withstand autoclave sterilizations and impacts, and provide gas and moisture barriers similar to conventional materials such as amorphous nylon or cyclo-olefins.
