THE SOLUTION Maintaining high organoleptic standards while easing processing windows can be difficult. Maintaining a seal for carbonated water with high internal pressure can be difficult and closurelogic caps compression molded with GLS TPE liners are known to have excellent pressure retention. THE IMPACT Caps made by closurelogic with Avient’s low migration cap liner technology preserve water quality while ensuring seal integrity.

The material facilitates two-shot molding, a highly efficient manufacturing process that eliminates time-consuming, high-cost assembly. It offers excellent surface engineering properties such as low wear, reduced friction, high lubricity, and no squeak. THE IMPACT The new premium mouse hit store shelves amid positive reviews, generating brisk sales and enabling the manufacturer to improve its share of market.
