Abstract
Biodegradable impermeable sheet, esp. for use in disposable hygienic napkins, consists of (I) a sheet-forming matl. that is non-biodegradable and resistant to water, and (II) 40-60, esp. 38-45 wt. % based on sheet, biodegradable material, that is homogeneously dispersed in I. Pref. also contains (III) less than 63 wt. % plasticiser, based on sheet. I is pref. water insoluble PVA or polyethylene. II is pref a starch, dextrin, or collagen. The sheet resists the penetration of body fluids. Satisfactory physical strength and flexibility. Is degraded rapidly by bacteria present in sewage.
