Editor’s call

Parkway Plastics, Inc. is an injection molder of plastic jars and caps at 561 Stelton Road, Piscataway, New Jersey, incorporated there in 1954, per the company site and corroborating trade coverage (Plastics Technology magazine; NJMEP manufacturer listing). It operates its own mold-making, tooling, and injection-molding lines and offers 500+ stock jar and cap SKUs, child-resistant closures, and in-mold labeling, serving pharmaceutical and nutraceutical brands among other markets. The company also wholesales its own stock, so it is a hybrid manufacturer-distributor; the self-made vs. resold split is not disclosed. No third-party certification is published, so none is recorded as confirmed. An openFDA food and drug enforcement screen returned no recall or enforcement record; on-site inspection was not conducted.
