Beschreibung
Zusammenfassung:	The present invention relates to a packaging material, base material for pressure-sensitive adhesive tape or separator, wherein a releasing agent layer, which can be discontinued so that a part of the support can be exposed, is formed on at least one surface of a film support. Further, the present invention relates to a packaging material, base material for pressure-sensitive adhesive tape or separator, wherein a releasing agent layer provided on at least one surface of a film support has cracks, through which the film support surface, i.e., the substrate, is exposed. Still further, the present invention relates to a structure of a sealing part of the above described packaging material etc. formed by heat seal processing of surfaces facing each other of releasing agent layers having cracks.
