The invention relates to a plasticizer-containing film based on partially acetalised polyvinyl alcohols containing partially acetalised polyvinyl alcohol, at least one plasticizer with a low polarity and at least one co-plasticizer of the formula R<SUP>1</SUP>-O(-R<SUP>2</SUP>-O)<SUB>n</SUB>-CO-R<SUP>5 </SUP>or the formula R<SUP>1</SUP>-O(-R<SUP>2</SUP>-O)<SUB>n</SUB>-CO-R<SUP>3</SUP>-CO-(O-R<SUP>4</SUP>-)<SUB>m</SUB>O-R<SUP>6</SUP>, wherein R<SUP>1 </SUP>to R<SUP>6 </SUP>are as defined herein. The plasticizer-containing films have a low tendency to exudation and can be used for the production of composite glazings.
