A food package (100), comprising a composition comprising a) a polymeric substrate comprising at least a first polymer, b) a preservative additive mixed in the polymeric substrate, the preservative additive selected from sorbates, such as potassium sorbate and calcium sorbate, benzoates, such as sodium benzoate potassium benzoate and calcium benzoate, and acids, such as benzoic acid, sorbic acid. The water contact angle of the first polymer is not more than 88°, specifically not more than 75°, more specifically not more than 70°. |
