A zipper is a closure system that helps keep a product fresh after opening, as the packaging can be re-closed to help preserve it. At SP GROUP we have developed a PP zipper that outstrips traditional ones in flexibility to ensure easy opening, not only on the packaging line, but also for end consumers, as this type of closure generally has issues related to the force required to open small pouches.

As an additional advantage, this zipper works very well with monomaterial polypropylene structures, as it permits a lower sealing temperature than the standard PP zipper. All this makes it the perfect closure for the new recyclable, retortable material PP HB ECO.

If you are interested in this type of closure and would like more information, please do not hesitate to contact us.
