Glatfelter Announces Advancements In Sustainable Materials For Espresso Pod Lids To Address The Growing Demand For Eco-Friendly Packaging Solutions In The Single-Serve Coffee Market

Glatfelter Corporation (NYSE:GLT), a leading global supplier of engineered materials, is proud to announce significant advancements in sustainable materials for espresso pod lids to address the growing demand for eco-friendly packaging solutions in the single-serve coffee market.

Building on its established reputation in the tea and coffee sectors, Glatfelter is expanding its sustainable product portfolio with a new biobased espresso lid material. This innovative lid material addresses the challenges associated with traditional polyethylene-coated aluminum film. Internal testing at Glatfelter has demonstrated that while alternatives such as Polylactic Acid (PLA) and Polyhydroxyalkanoates (PHA) provide some environmental benefits, they fall short of meeting the essential requirements for espresso lids. These requirements include maintaining effective oxygen and moisture barriers, ensuring compatibility with existing equipment, achieving a clean puncture under high pressure, supporting crema formation, and providing peel-free adhesion—all while being home compostable.

When paired with a compatible capsule, this new lid would allow the entire espresso pod to be composted at home, reducing its environmental impact. The European Commission's Proposal for Packaging and Packaging Waste Regulation (PPWR) highlights the importance of compostability for coffee capsules, noting that coffee grounds contain valuable nutrients such as potassium, phosphorus, and nitrogen, which can enrich soil if composted (Statement on the Revision of the PPWR, 2024).i
