learn moreIn 2019 the EU voted the Single Use Plastics (SUP) Directive on how to deal with single-use plastic products. Under this Directive, in the future, drinks will only be allowed to be sold in plastic containers if the tethered cap / tethered closure remains attached to the container.
Early 2021 National laws transposed from the Directive has come into force. This has made tethered closures an omnipresent topic in the packaging industry.
Zalkin had already started to work with its partners and customers and can adapt the existing capping machines to be ready by 2024.
Zalkin know-how allows to develop innovative capping applications, including lightweight and tethered.
The Directive on tethered closures highlights how crucial it is that designs combine circular economy and consumer-friendly tethered closures. This is why Zalkin has worked hard with cap and packaging manufacturers to find solutions for caps that not only meet the sustainability requirements but also improve consumers’ experiences.
Zalkin has a long experience in helping develop new caps and building turrets and cap-sorters for tethered caps.
With its ZC Lab test laboratory Zalkin has advised and assisted for developments on
Tethered caps have to offer customers the same physical performance as standard closures.
To achieve this requirement the cap and the way it is applied to the bottle has to be updated, and sometimes even redesigned.
Closures ideally need to be implementable without the need for modifications to the neck finish and without any loss of efficiency in the handling processes.
Various solutions have been developed that can be adapted to all important bottle neck sizes
In close cooperation with our customers we have pioneered since 2015 the tethered snap cap in the water industry. This has been a great challenge and success as today millions of water bottles are tethered-capped with our machines all over the world.
Our cappers are capable of reaching high speed when capping either still or sparkling water.
This long experience in building or converting machines for tethereds cap places Zalkin in the best position to help our customers in all the phases of this major change.

The SUP directive in a nutshell
Objective of this new directive
Proposed solution
In the EU definition, all closures for PET bottles for beverages should be converted to tethered by 2024.
Impact on environment & packaging collection rates
Reducing the impact of single use plastic on the environment
Beverage PET bottles will have to contain
Necessary measures to collect separately an increased amount of waste single-use plastic products for recycling:
Impact on other liquid & dairy products
Tethered caps are not only snapped for water
Next to this first solution, cap manufacturers and packaging companies have developed tethered screw caps for PET bottles and worked on solutions for HDPE bottles/containers.
The snap clic closure originally for water PET bottle has already been adapted for dairy products and meets the SUP directive.
