The Steri-Shield 38mm closure features a taller profile than the non-TE version to provide brand owners with a different aesthetic profile. The category has traditionally used closures with thermoplastic elastomer (TPE) or foil liners to achieve seal integrity for both low- and high-acid beverages. By eliminating the liners, the plug design helps minimize package cost and contribute to material source reduction.
The linerless TE plug closure is compression molded using high-density polyethylene, resulting in a lightweight closure that can withstand an aseptic sterilization environment of up to 140 degrees Fahrenheit as well as the rigors of distribution. The closure is said to be easier for consumers to open because there is no liner to negatively impact torque.
Closures can be made in a variety of sizes ranging from 38 to 43mm, with or without a tamper-evident band. The line suitable for a wide range of aseptically-filled beverages including: juices, isotonics, dairy, energy drinks, milk, vitamin waters, drinkable yogurt, teas, and more.
