Transpirant biodegradable film and absorbent sanitary articles incorporating it

摘要

The present invention relates to a film made of a biodegradable thermoplastic material which allows the passage of water vapour by the presence of a series of micro-pores passing through it and which is impermeable to liquids due to a specific gram-surface ratio of 18-27.5 g/m<2>. The invention also relates to absorbent sanitary articles which incorporate said film as an external wrapping for containing body liquids and for allowing skin perspiration. <IMAGE>
