    Abstract: A biodegradable sheet comprising first and second outer polymer layers and at least a first inner polymer layer between the two outer layers wherein the first inner polymer layer comprises poly-caprolactone at a wt% of 35-45 of the total layer weight and a second polymer from the group of, poly-lactic acid, poly-butylene succinate, poly-butylene succinate adipate or a mixture thereof at a wt% of 55-65. The polymer layers may be co-extruded. The first outer polymer layer may comprise pol-butylene succinate and may further contain poly-hydroxyalkanoates. The first outer layer may instead comprise poly-butylene succinate adipate or poly-butylene adipate terphtalate and optionally also poly-lactic acid. The second outer polymer layer may comprise poly-butylene succinate adipate and optionally further include poly-caprolactone or may comprise poly-butylene adipate terphtalate with optional poly-lactic acid or may comprise poly-butylene succinate or a mixture of poly-butylene succinate adipate and poly-lactic acid. Second and third inner polymer layers may be included and the first inner polymer layer may be metalised on one or both sides.

    Abstract: Disclosed is a biodegradable sheet comprising at least one layer which is a direct contact layer, intended to successfully contact materials, such as liquids, while maintaining the mechanical properties of the sheet and to extend the biodegradable sheet shelf life. The direct contact layer may comprise a hydrophobic polymer selected from poly(epsilon-caprolactone) (PCL) polyhydroxybutyrate (PHB), Polydioxanone (PDO) polyglycolic acid (PGA), polybutylene succinate (PBS), polybutylene succinate adipate (PBSA), poly lactic acid (PLA), polybutylene adipate terphtalate (PBAT), polyhydroxyalkanoates (PHA), such as polyhydroxybutyrates (PHB), polyhydroxyvalerates (PHV), and polyhydroxybutyrate-hydroxyvalerate copolymers (PHBV) or any mixture thereof. The biodegradable sheet may further comprise surface treated nanoclay particles, PVOH grafted with a crosslinker and PBS or PBSA The first hydrophobic polymer is present in said at least one layer in an amount of about 30% w/w.
