Claims35
A substrate with a surface having
- a coating comprising a material, wherein the material of the coating comprises:
- a layer (A comprising a polysaccharide which has been derivatised to comprise fatty acid ester moieties,
- wherein the polysaccharide is derived from seaweed and is selected from the group consisting of agar, carrageenan, alginic acid, an alginate salt, fucoidan, laminarin, agarose, agaropectin and ulvan;
- and wherein the substrate is or comprises a packaging material.
A substrate with a surface having
- a coating comprising a material of the coating, wherein the material comprises:
- a layer (B) comprising an un-derivatised polysaccharide.
A composite material comprising:
- at least one layer (A) comprising a first polysaccharide which has been derivatised to comprise fatty acid ester moieties;
- and
- at least one layer (B) comprising a second polysaccharide which is un-derivatised.
