The FreshSeal XL III liner provides gas barrier levels equal to or better than foil, as tested by an independent laboratory, the company stated in a pressrelease.
"Our customers can now have a choice if they don't want to continue using foil seals," says Ken Corbett, global category manager for O-I. "This producthas the potential to eliminate the need for foil seal in hotfill and aseptic applications."
Molded-in liners have been developed by many companies, but the hardness of previous liners could cause issues with sealing, the company claims. O-I says its FreshSeal XL III liner is much softer,allowing the closure to consistently seal tightly.
The molded-in feature differs from traditional lining systems that rely on a separate cut, glue and insertion process.
"Depending on closure size, run quantity and other factors, there are potential sizeable cost savings with molded-in liners compared to traditional cut and insert liner seals," Corbett said.
