Offers excellent sealing for beverages containing CO2 in PET bottles potentially exposed to high temperatures.
Extreme conditions call for extreme packaging. That’s why CSI developed the Double-Lok HR 28mm closure. For beverages packaged in PET bottles, this cap maximizes 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 less than 5˚ C to over 50˚ C. 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.
Innovative Double-Lok HR liner maximizes seal integrity and product freshness, even at temperatures as high as 60˚ C, using a plug-side-seal and top seal design.
Double-Lok HR’s inner liner profile compensates for neck shrinkage in PET bottles by remaining in continual contact with the bottle finish, preventing CO2 from escaping.
Double-Lok HR 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.
