Portola Packaging will be strongly targeting producers of milk, yoghurt, smoothie and other non-carbonated drinks with its new pull ring "California" neck insert, designed to be compatible with "a host" of existing primary cap designs.
It says the plastic pull ring closure, developed at its Doncaster site, offers plastic bottle users the flexibility to switch to a pull ring closure “without the time, inconvenience and cost constraints of having to modify existing capping equipment”.
The neck insert can be fitted on conventional capping lines, is compatible with standard 38mm single-start bottle necks and other commonly-used dairy bottle necks and incorporates a pouring lip and dual seal anti-leak technology, with parts fixed by a permanent foil bond. Portola says its design also means pack height is maintained after fitting, allowing customers to enjoy pack appearance uniformity when California is used alongside other closures.
