FIELD: biotechnology.
SUBSTANCE: biodegradable sheet material contains nano-clay and polyvinyl alcohol (PVOH). Nano-clay is nano-clay based on montmorillonite, vermiculite, nano-kaolin, bentonite, Cloisite® or any combination thereof. The invention also relates to a biodegradable sheet material having an inner layer in which the inner layer comprises polyvinyl alcohol (PVOH) and can consist of five layers: layer 1: in a weight ratio, consists of 25% of polylactic acid (PLA) and 75% of polybutylene succinate adipate (PBSA); layer 2: in a weight ratio, consists of 100% polybutylene succinate adipate (PBSA); layer 3: in a weight ratio, consists of 100% polyvinyl alcohol (PVOH); layer 4: consists of 100% polybutylene succinate adipate (PBSA) and layer 5: in a weight ratio, consists of 25% of poly-lactic acid (PLA) and 75% of polybutylene succinate adipate (PBSA) or layer 1: in a weight ratio, consists of 25% of polylactic acid (PLA) and 75% of polybutylene succinate adipate (PBSA); layer 2: in a weight ratio, consists of 90-85% of polybutylene succinate adipate (PBSA) and 10-15% of nano-clays; layer 3: in a weight ratio, consists of 100% polyvinyl alcohol (PVOH); layer 4: in a weight ratio, consists of 90-85% of polybutylene succinate adipate (PBSA) and 10-15% of nano-clays and layer 5: in a weight ratio, consists of 25% of polylactic acid (PLA) and 75% of polybutylene succinate adipate (PBSA). The invention also relates to a container made from the said biodegradable sheet material, including a storage compartment for liquids and a device for liquids removal therefrom.
EFFECT: improved properties of compounds.
