摘要：
A foil made of two plastic films and an adhesive layer laminating the two films together, wherein the first plastic film has a first side and a second side and comprises punctures therebetween. The foil is of a dual peel-seal type such that the first plastic film realizes a first peel-able seal within the foil at its first side in the form of an adhesion peel seal in an open state and/or in the form of a cohesion peel seal in a sealed state, and wherein the adhesive layer leaves open the punctures such that gas can penetrate through the punctures in-between the two films towards the first peel-able seal.
