Press-to-Close
A staple amongst convenient flexible pouches, the press-to-close closure provides ease of use, maintains product freshness and enables portion control. See individual press-to-close closure options below.
Innolok®
Available from Sonoco, the Innolok® resealable closure integrates on the pouch face. Available as a rollstock solution for vertical form fill seal (VFFS) applications or integrated into a bag or pouch.
SealTab®
SealTab® is a unique reseal technology that eliminates the need to repackaging after opening. Not only does this improve shelf appeal, it also saves on total package weight when compared to a zipper closure.
SmartSeal®
Another innovative closure technology from Sonoco, SmartSeal® integrates resealability and tamper evidence ensuring the freshness, convenience, and product safety consumers demand - while protecting your brand integrity.
Fitments
When paired with innovative fitments, pouches take on new functionality, offering precision in dispensing and extending shelf life with reclosable spouts. Food consumers see the light-weight, on-the-go convenience as a way to support their active lifestyles, and new innovations are gaining traction for a broader range of applications such as household cleaners and garden items.
