2025 World Star Award Winner: EcoPeelCover

Constantia Flexibles have recently been awarded a World Packaging Award for their EcoPeelCover.

Privatmolkerei Bauer, a leading German dairy producer, sought to improve the sustainability of its packaging without sacrificing performance.

To meet this demand, Constantia developed a thinner, more eco-friendly die-cut lid for their polypropylene (PP) cups, commonly used in the dairy sector. The primary goal was to significantly reduce material usage, optimizing material and energy efficiency. Traditional die-cut lids feature aluminum layers of 38µm with 24 grams/m² extrusion coatings. The Constantia team achieved this by developing EcoPeelCover, featuring a 25µm aluminum thickness and a 13 grams/m² extrusion coating, which provides the sealing function.

EcoPeelCover sets itself apart as the thinnest die-cut lid on the market, incorporating an ultra-thin aluminum layer and coextruded PP. Despite its reduced thickness, it delivers exceptional peelability, corrosion protection, and puncture resistance. The lid also provides superior barrier protection against moisture and oxygen, ensuring the dairy products remain fresh and protected.
