Extreme conditions call for extreme packaging. That’s why CSI developed the Wing-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.
Wing-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.
