In 2019, the European Union adopted the Single-Use Plastics (SUP) Directive on how to handle single-use plastic products. Under this directive, beverages can only be sold in plastic containers if their cap remains attached.
At the beginning of 2021, the national laws transposing the directive came into force.
Zalkin had already started working with its partners and customers and can adapt existing capping machines to be ready for 2024.
Zalkin personalized development
Zalkin's expertise enables the development of innovative, particularly for lightweight and tethered caps.
The The SUP Directive underscores the crucial importance of combining circular economy principles with consumer-friendly caps. That's why Zalkin has worked closely with cap and packaging manufacturers to develop cap solutions that not only meet sustainability requirements but also enhance the consumer experience.
Zalkin has extensive experience in developing new caps and constructing turrets and orientors for tethered caps.
With its testing laboratory ZC Lab, Zalkin provided advice and assistance for developments on:
- the capsules
The solidarity capsules must offer customers the same physical performance as standard caps.
To meet this requirement, the cap and the way it is applied to the bottle must be modified, and sometimes even redesigned.
- the bottle necks
These capsules should ideally be achievable without requiring modification of the neck finish and without any loss of efficiency in the handling processes.
- the capping processes
Various solutions have been developed that can be adapted to all common bottle neck diameters, with minimal conversion effort and without negatively affecting application processes
Zalkin has extensive experience in water bottles with tethered caps
Working closely with its customers, Zalkin has been a pioneer in the push-in, tamper-evident cap for the water industry since 2015. It has been a major challenge and a resounding success, as today millions of water bottles are capped with its machines worldwide.
Zalkin capping machines are capable of achieving a high throughput when capping still or sparkling water.
This long experience in the construction or transformation of machines for tethered caps puts Zalkin in the best position to support customers in all phases of this major change.
