Due to their excellent properties, polyolefins such as polypropylene and polyethylene are widely used in food packaging applications to preserve and protect foodstuffs. Meanwhile, polymeric food packagings are not inert and migration of additives or their degradation products from packaging to food is a well-known issue, covered by European Commission (EC) regulation related to food contact materials [1], [2] and 0175. Moreover, during their lifecycle or first use, substances can penetrate into polymer packagings especially with polyolefins. This possible contamination strongly limits their recyclability as recycled food contact material (closed loop recycling) due to the food contact material regulation, EC 10/2011 [3]. In fact, these previously absorbed components might be released from recycled packaging, and migrate into the foodstuff to contaminate it [4].
