Tetra Pak, in partnership with Elvir, a subsidiary of Savencia Fromage & Dairy – a world leading milk processor – has become the first carton packaging player in the food and beverage industry to launch a cap using certified recycled polymers.

This move marks a key step in both companies’ progress towards circularity. By helping to find an economically sound use for plastic waste and responsibly sourcing raw materials, Tetra Pak and Elvir continue to minimise their dependency on virgin, fossil-based resources.

Elle & Vire chose the HeliCap 23 cap solution to complement its cream products, which are distributed in Tetra Brik® Aseptic 1 l Slim carton packages. This one-step resealable screwcap is manufactured at Tetra Pak’s Châteaubriant plant in Loire-Atlantique, France – a site that has been awarded the Roundtable on Sustainable Biomaterials (RSB) Advanced Products certification and boosted by a EUR 100 million investment to accelerate the transition to the production of tethered caps. The HeliCap 23 cap offers consumers ease of opening and features a clearly visible tamper evidence ring, providing reassurance that the product hasn’t been opened before.

The new caps using attributed recycled polymers are manufactured under the RSB chain of custody attribution method. This means that the plastics are made of a mix of recycled and non-recycled materials, with the corresponding mass of recycled materials tracked throughout the Tetra Pak supply chain. This is verified by a third-party auditor according to the RSB Chain of Custody Procedure, which forms part of the RSB Advanced Products certification.

SIG is once again leading the industry on sustainable innovation by being the first to offer beverage cartons made with recycled polymers produced from post-consumer plastic waste.

SIG customers will be able to respond to consumer demand for packaging made with recycled plastics by choosing SIG cartons made with certified circular polymers. This innovation reinforces SIG’s contribution to the circular economy by making use of low quality, mixed plastic waste that would otherwise be incinerated or sent to landfill. The mixed plastic waste that is collected is treated in a process that enhances the material and transforms it into a high-quality food grade material.

Made primarily from renewable, FSCTM-certified paper board, SIG’s beverage cartons already support the circular economy by promoting the regeneration of vital natural resources in responsibly-managed forests.

Pioneering partnership

SIG is among a select group of companies – and the first in the beverage carton industry – to partner in the foundation stage of development of recycled polymers from post-consumer waste by its supplier, SABIC. This pioneering partnership highlights SIG’s commitment to a more sustainable future through new solutions that support a circular economy.

The recycled polymers offer the same high quality and have the same properties as polymers made entirely from virgin raw materials. Any contaminants are eliminated during processing, making the recycled content completely safe for food packaging.

Certified circular polymers

The recycled polymers offered by SIG will be certified to the ISCC PLUS standard to enable customers to trace recycled content throughout the value chain from post-consumer waste streams to processing and use in the production of new cartons.

SIG’s commitment to sourcing certified sustainable materials is part of its ambition to go Way Beyond Good by putting more into the environment and society than it takes out.
