Polymeric materials are described which have a bioflavonoid coating, the bioflavonoid content of the coating comprising at least naringin and neohesperidin. The use of such coated polymeric materials is also described as well as the process for making the coated polymeric materials. Naringirin and neohesperidin preferably form 50 80 % of the bioflavonoid content. Further bioflavonoids may be neoeriocitrin, isonaringin, hesperidin, neodiosmin, naringenin, poncirin, rhiofolin or oleuropein. A further component may be salicylic acid or fruit acids like citric acid, lactic acid, ascorbic acid or malic acid. The polymeric material may be a synthetic polymer such as polyethylene terephthalate (preferred), polyethylene, polypropylene, polyvinylchloride, polyamide, polyvinylidenchloride, polyethylenvinyl alcohol, polyethylene vinyl acetate, neoprene, latex, nitril rubber or silicone. The bioflavonoid-coated polymers may be used in food packaging such as meat, specifically poultry (chicken, turkey). It may be used as a poultry napkin. The bioflavonoid coating can be applied by immersion, spraying or surface blasting and the polymeric material may undergo a plasma treatment before it is coated.
