Two years developing an advanced closure

Leading closure specialists Silgan White Cap Europe/Asia has introduced a new closure into its advanced Plastic-Twist® range.  The 38mm CVT Plasti-Twist, which is the result of two years of development work, has been designed for cold and aseptic fill applications such as juices, health drinks, iced tea, fresh milk and milk drinks.

The linerless closure is compression moulded in polyethylene and features a d-tamper evident band. It is suitable for use with PET, PP and HDPE bottles.

A special triple seal function provides three contact sealing areas for the closure and the container – top, inner and outer – which ensures a hermetic, airtight seal. Other important features include pull-up controls that correspond to controls on PET bottles for immediate non-destructive visual checks of good closure application, which helps to maximise production line efficiencies.

The matt (as opposed to gloss) surface finish provides enhanced printing opportunities for additional branding and personalisation of the closure.


The intense development process for the 38CVT included extensive Secured Seal Testing (SST) and Opening Performance Testing (OPT 180) to create a closure that meets the safety requirements of today?s consumer. Pack integrity before opening is assured since the closure is able to hold a pressure well above 2.08 bar until after the tamper band breaks.

“Our approach to new product development is clear – whatever the market needs, we will provide it,” comments Mark Hewett, Silgan White Cap Europe/Asia?s Manager Profit Centre Plastic. “The 38CVT has been developed to exactly meet customer requirements.”

As a result, the closure has already been approved by a leading worldwide beverage company, making Silgan White Cap Europe/Asia only the second supplier to have achieved this qualification.
