As part of a wider programme, 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.

Commenting on the announcement, Julia Luscher, vice president marketing at Tetra Pak, said: “We are delighted to be supplying a number of customers with tethered cap solutions, helping them to ‘walk the talk’ towards their sustainability ambitions. Understanding our customers’ needs and having collected consumer insights through multiple pieces of research across various markets, our new tethered caps have been designed to enhance convenience. For instance, they are easy to open and re-close for subsequent consumption, while featuring carefully sized diameters for smooth pouring and drinking.”

Tethered caps play an important role in preventing litter, as the cap will stay attached to the package. They could also help reduce the carbon footprint of the carton when they are chosen by food manufacturers as plant-based options, 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%.
