PT – Press On Twist-Off®


The Original for Premium Products

A special vacuum-holding closure with excellent oxygen barrier properties offering extended shelf life for premium food segments. PT is designed for high speed press-on and twist-off operation, with superior tamper resistance and a hygienic construction, achieved by an extended compound side wall in a closure shell without lugs.

Experience the PT difference:

  • Vacuum packaging – The Vapour-Vacuum System® is applied during the capping operation to ensure minimal oxygen in the headspace of the container
  • Food preservation - Unrivalled oxygen barrier properties are achieved through the use of tin plated steel combined with specially designed compound materials for the sealing gasket. This airtight seal protects food from contaminants and minimises Vitamin C degradation or discolouration
  • Convenience – Easy to open, easy to reseal, while the tight reseal after initial opening allows opened jars to be stored in the refrigerator and ensures odours cannot escape and mix with other food products
  • Regulatory Compliance - Materials used to manufacture Silgan White Cap metal closures comply with the latest requirements of European food contact legislation
  • Sustainability - Metal closures can be fully recycled. Steel does not show any loss of quality. This process can be repeated continually as part of a closed loop system. The combination of metal closure and glass container offers a truly sustainable packaging solution
