Ahlstrom introduces an innovative home compostable lid for single-serve coffee capsules

PureLid™ is  a fiber-based lid offering for single-serve coffee capsules to support the coffee industry in its sustainability journey. With its ground-breaking design, PureLid™ offers a high-performing, home-compostable alternative to aluminum or plastic lids used in coffee capsules. 

PureLid™ has received the OK compost HOME and OK compost INDUSTRIAL certifications from TÜV®. OK compost HOME and OK compost INDUSTRIAL certifications confirm that PureLid™ can be composted at home and in an industrial facility. All tests have been carried out with an independent laboratory certified and accredited to ISO 17025.

This innovative, patented coffee lid structure is ready to seal on coffee capsules, making it an ideal choice for manufacturers who are looking to embrace the future of sustainable coffee packaging.

PureLid™ is compatible with the most common bio-based coffee capsules on the market, making it a versatile choice for coffee brands looking to reduce their environmental footprint. PureLid™ also features an adequate Oxygen Barrier that preserves the coffee’s flavor and freshness.

Furthermore, PureLid™ incorporates a built-in filter that effectively retains dust, ensuring optimal brewing performance and a consistently pure coffee taste with every cup. One of the remarkable features of PureLid™ is its transition from industrial compostability to home compostability while preserving capsule performance and the critical oxygen barrier.

“It was a substantial challenge to transition from industrial compostable solutions to home compostable ones while maintaining the high-performance standards of our coffee capsule lidding solutions and the crucial oxygen barrier. However, our team’s dedication and expertise have made PureLid™ a reality, setting a new standard for sustainable coffee packaging,” says Philippe Sevoz, Vice President of the Beverage & Casing business.

“Ahlstrom is committed to sustainability and innovation, and PureLid™ is a testament to our dedication to creating sustainable solutions for the coffee industry. We believe that PureLid™ will not only enhance the coffee experience but also contribute to a more sustainable future for our customers and their consumers,” Sevoz concludes.
