Wing-Lok HR 28mm

Wing-Lok HR 28mm maximizes CO2 sealing performance for beverages packaged in PET bottles.

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.

  • Easy-to-open exterior design
  • Excellent resealability
  • Secure Wing-Lok tamper-evidence, providing visual and tactile confirmation when the band breaks for consumer safety, without compromising bottling line performance
  • Built-in venting slots for safe venting of excess pressure
  • Under-the-Cap promotion – video-jet print, laser print, or embossed liner
  • Extensive range of shell colors to attract customers
  • Precise multi-color top printing for clear communication
  • Easy to recycle – environmentally friendly
  • Industry-leading application performance
  • Designed for Pick and Place and Direct Pick-Up application
  • Interchangeable with Wing-Lok set-up
