    • The invention relates to pouch or bag-shaped beverage containers (1) having an opening system which is pierced by a straw to access the beverage. The container includes a wall (14) which is a multilayer laminate which from the outside to the inside includes polyester film (3), printing ink (4), adhesive (5), foil (6), adhesive (7) and polyethylene film (8). In order to facilitate piercing of wall (14) by a straw, a portion of the outer polyester film is removed at an area (2) which is intended to be pierced by a straw as is known in the art. To further facilitate piercing of wall (14) an area of delamination (9) is created opposite area (2) between foil layer (6) and the polyethylene film (8). Area of delamination (9) is created by vaporizing adhesive layer (7) by means of laser radiant energy which is transmitted through the polyethylene film (8) and absorbed by adhesive layer (7).
