Beschreibung
Zusammenfassung:	Provided is a PVA film using PVA that does not increase carbon dioxide existing in the global environment or has a small increase amount even when carbon dioxide is generated by a biodegradation treatment or an incineration treatment.The present invention is a polyvinyl alcohol resin film comprising a polyvinyl alcohol resin (A), wherein an abundance ratio of carbon 14 (14C) in total carbon constituting the polyvinyl alcohol resin (A), that is, 14C/C is 1.0 × 10-14 or more.
