Specifically designed for PET beverage bottles to maximize CO2 sealing performance and product freshness under the most demanding conditions.
CSI research shows that filled PET bottles can be subjected to extreme “temperature cycling” – from 40˚ F to over 135˚ F. These conditions can cause shrinkage of the heat-sensitive PET material, which can cause a gap to develop between the bottle finish and the closure. The result is loss of CO2 and product freshness.
Extra-Lok XT improves the mechanical seal, and maximizes product freshness in conditions where extreme temperatures can cause package leakers throughout the distribution channel. CSI’s proven application performance and capping equipment provides bottlers with the best sealing performance in the industry under extreme temperature cycling conditions.
In addition to precision made quality closures, CSI provides capping equipment and unparalleled customer and
technical service across the globe.
CSI’s closure systems solutions and ongoing innovation help our partners maximize profits by increasing the
marketability of their brands and optimizing their total cost of operations.
