Portola Packaging, Inc. introduces GreenLyte™, a line of plug-seal, high-density polyethylene (HDPE) 38-mm closures for single and multiserve, hot-fill and aseptic beverage packaging applications. 

GreenLyte™ one-piece closures represent a cost-effective, performance-driven alternative to traditional two-piece (closure plus liner) polypropylene (PP) types typically used for juices, ready-to-drink teas, isotonics, enhanced waters, low-acid nutraceuticals, and high-end, aseptic-filled beverage products.

Because the GreenLyte line is made from HDPE, it is less expensive than volatility-prone PP resins, from which most two-piece closures are made. 

GreenLyte plug-seal closures also offer multiple production line efficiencies. Unlike two-piece closures, which usually require that the TPE liner be steamed in order to achieve proper application, this step is not necessary with Portola’s linerless GreenLyte line. Additionally, the seal design and low coefficient of friction facilitates application over a range of capper settings.
