The thickness of the sealing layer is generally at least 10 clam, preferably it is at least 20 pm, and even more preferably at least 30 calm. As the polymer used for the sealing layer may also be used to provide the desired thickness to the film, in some instances very thick sealing layers will be present, such as in the case of a 3-layer structure.
