In general terms present invention proposes a biodegradable packaging material (100). The biodegradable packaging material comprises an inner layer (102) comprising an enhanced polymeric substrate: an outer layer (104) comprising a printable substrate; and a middle layer (106), arranged between the inner layer and the outer layer, comprising at least one functionalized graphene layer, wherein the biodegradable packaging material is suitable for an anaerobic digestion, when disposed. In general terms present invention also proposes a method for manufacturing the biodegradable packaging material.

The invention relates to a polymer film obtainable from the crosslinking reaction between pectin and carboxymethylcellulose in the presence of an organic calcium salt and a plasticiser. The film can comprise zeolite, loaded or not loaded with silver ions. The organic calcium salt is selected from: calcium propionate, calcium acetate, calcium lactate, calcium sorbate, calcium glutamate, calcium oleate, calcium palmitate, calcium laurate, calcium stearate and calcium myristate. The plasticising agent is a saturated or unsaturated fatty acid selected from: oleic acid and palmitic, stearic, lauric, myristic, myristoleic, palmitoleic and linoleic acid; polyethylene glycol; glycerol; glycerol derivatives; and citric acid salts, preferably sodium citrate. The polymer film can be laminated to at least one film/layer of plastic material, possibly biodegradable, or to a layer of paper and used for packaging foods, in particular baked products, with the aim of preserving them and extending their shelf life.
