SWITZERLAND – Top European beverage brands have adopted Tetra Pak manufactured tethered caps on carton packages in an effort to cut down on litter associated with single-use packaging. 

Bottle caps have become an environmental concern because they often end up being thrown in the general waste bin or dropped as litter. 

The 2017 International Coastal Cleanup, an annual beach cleanup event run by ocean advocacy group Ocean Conservancy, reported that plastic bottle caps were the third most collected item worldwide 

These caps pose a significant environmental hazard as they are small enough to be ingested by wildlife and also break down into microplastics when left in the environment. 

Tethered caps on carton packaging is said to be “litter proof” because they keep the cap attached to the bottle all the way up to when it is collected and recycled. 

Joining forces with 5 leading beverage producers across Europe, Tetra Pak has launched tethered caps on carton packages.  

Irish water producer Borrisoleigh Bottling Ltd and its Spanish counterpart LY Company Group are among the 5 companies adopting tethered caps on carton packages for their packages. 

Others include Lactalis Puleva – part of the Lactalis Group, Weihenstephan, one of the oldest and most popular German dairy brands, and Cido Grupa, a leading juice producer in the Baltics region. 

The company says that the launch marks a significant milestone in the company’s long-term work on design for recycling. 

The five new tethered cap solutions are currently being introduced across Ireland, the Baltics , Spain and Germany in different product categories – a market first for these geographies.  

Apart from helping the companies significantly cut down on litter, Tetra Pak says this development paves the way for Europe-based customers to stay ahead of schedule and meet the Single Use Plastics (SUP) Directive coming into force by 2024. 

Julia Luscher, , comments: “We are delighted to be supplying a number of customers with tethered cap solutions, helping them to ‘walk the talk’ towards their sustainability ambitions.” 

Luscher says that the new tethered caps have been designed to enhance convenience as they are easy to open and re-close for subsequent consumption. 

Vice President of Marketing at Tetra Pak further noted that the caps were carefully sized diameters “for smooth pouring and drinking.” 

They could also help reduce the carbon footprint of the carton as they are made from polymers derived from responsibly sourced sugarcane, thereby increasing the renewable content of the package.  

Additionally, a majority of Tetra Pak’s tethered cap portfolio features a reduced amount of plastic. Depending on the various solutions, the company achieved a plastic content reduction ranging between 7% and 15%.    

Tetra Pak plans to equip approximately 300 packaging lines with tethered caps in Europe by the end of 2022 and expect to sell over 1.5 billion such closures by year end. 

The company has also heavily invested towards an improved manufacturing experience for customers.  

According to Machetti, the company is investing around €400 million in the development and roll-out of tethered cap solutions. 

The investments include a €100 million investment last year in Tetra Pak’s Châteaubriant plant in France to accelerate the production of tethered closures.
