Social and political pressures are stimulating a rapid growth in environmental legislation and the framework of national and European directives is reviewed. The pressure for recycling and the incorporation of recycled material is at risk of conflict with safety for food contact packaging. Various recycling opportunities are reviewed, concluding that recycling must be directed only to where there is an environmental benefit; also that re-use must not jeopardize food safety. For direct food contact with foodstuffs, chemical recycling is the only confident way of ensuring product purity. Containment of recycled material behind a barrier layer leaves the question of barrier performance to undefined contaminants.
社会和政治压力正促使环境立法迅速发展，国家和欧洲指令框架也在接受审查。回收利用以及使用回收材料的压力可能与食品接触包装的安全性产生冲突。对各种回收机会进行了审查，得出的结论是，回收必须仅针对具有环境效益的领域；同时，再利用不得危及食品安全。对于与食品直接接触的情况，化学回收是确保产品纯度的唯一可靠方法。在阻隔层后面使用回收材料会使阻隔性能对于未定义污染物的问题变得不明确。
