The variety and versatility of plastic closures present much for consideration

摘要

Plastic threaded closures (hereafter, closures) have wide applications with bottles and jars, sure; however, not to be forgotten are applications with tubes (metal and plastic), cartons (gable-top and aseptic), and flexibles (single-layer and multi-layer bags). With closures being a key component in so many packaging systems, considerable thought and planning are required for the optimal compatibility between that component and the other components of the system.
