Flexible plastic packaging (films) is currently in the most part unrecyclable, mainly due to the multi layer construction of films, in order to retain barrier properties to keep food fresh. One of the main components used is a nylon (PA) material which acts as a gas barrier, sandwiched between Polyethylene (PE). While this PA layer helps reduce food waste (extending food life from 3 days to up-to 26 days), it also renders the film unrecyclable.PA is also produced from a fossil fuel sources, and requires precurrosor chemicals such as adipic acid which are highly polluting, with large amounts of CO2 and N02 produced as a result.Impact have identified a method to develop a bioNylon - BioMide - from algae. The material is produced from a bio, renewable source, and able to be grown in bioreactors negating the need to displace agricultural land. Unlike traditional bio processes there is no fermentation requirement and the process is therefore carbon negative. The material produced has the same properties as conventional PA, with the added benefit that they can be biodegraded during the current recycling process, allowing a multi layer PE-PA film to be recycled in the same method as a single layer PE film.This has the potential to not only offset large amounts of carbon released into the environment, but also make over 4Mt of unrecycled film easily and readily recyclable, without the need for any additional recycling infrastructure.

柔性塑料包装（膜）目前在大多数情况下，主要是由于膜的多层结构，以保留屏障特性以保持食物新鲜。所使用的主要组件之一是尼龙（PA）材料，该材料充当气体屏障，夹在聚乙烯（PE）之间。虽然该PA层有助于减少食物浪费（将食物寿命从3天延长到最新的26天），但它也使薄膜不可固定。PA也是从化石燃料来源生产的，并且需要先天性化学物质，例如脂肪酸，例如脂肪酸产生的高度污染，产生了大量的二氧化碳和N02。Impact已经确定了一种从藻类开发二甲基的方法。该材料是由生物，可再生来源生产的，并且能够在生物反应器中生长，否定了替代农业土地的需求。与传统的生物过程不同，没有发酵要求，因此该过程为碳负。所产生的材料具有与常规PA相同的特性，其额外优势可以在当前的回收过程中进行生物降解，从而使多层PE-PA膜以与单层PE膜相同的方法进行回收。不仅可以抵消大量碳释放到环境中的潜力，而且还可以轻松易于回收，而无需任何额外的回收基础架构，也可以轻松易于回收。
