The laminate bag is formed by two film layers, one external and gastight (16), and one internal (17,19) for reinforcement. At least one of the film layer contact surfaces has a regular pattern of indentations (17a) which reduce the actual locating surfaces between the layers. - This allows heat sterilisation of the mouthpiece without risk of localised welding together of the surrounding areas of the film layers. |
