• a support composed of a vegetable parchment;
• wherein the compostable lid extends from a first surface to a second surface, the non-woven material positioned proximal to the second surface and the support positioned proximal to the first surface, with the adhesive layer positioned between the non-woven material and the support;
• and
• wherein the second surface of the compostable lid is affixed to a surface of a flange of a capsule body of the beverage capsule to seal the beverage capsule, with the non-woven material facing inwards towards the beverage capsule;
• wherein the grammage of the non-woven material is between 5 and 100 g/m2;
• wherein the vegetable parchment layer has a wet burst strength measured according to ISO 3689 and a dry burst strength measured according to ISO 2758, and wherein the ratio of the wet burst strength to the dry burst strength is between 50 to 70 percent.
