Extreme conditions call for extreme packaging. For beverages packaged in PET bottles, this cap maximizes CO2 sealing performance and product freshness under the most demanding conditions. Manufactured in Polypropylene.  CSS 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.
