Separating laminated plastic packaging films using solvent dissolution

层压塑料包装的增长率约为14%。但是这些材料不能回收，因为它们是物理结合的，不容易分离。它们主要由PET（层压膜的主体）和另一种聚合物组成，通常是PP或PE，用作非常薄的衬里膜，用于食物接触和盖子密封。包装通常含有2 - 10%的PP/PE。PET用于生产各种各样的产品，对回收PET的需求正在增长。为了避免填埋或焚化费用，回收层压PET的需求将越来越大。主要的挑战是分离这些物理结合的聚合物。我们的想法是利用溶剂溶解更小的PE/PP，通过使用超声波技术大大加速，留下干净、固体的PET。我们的目标是加工PET并将技术许可给其他PET回收商。我们可以授权PET回收系统制造商建立工厂并销售许可证，从而在英国和欧盟广泛开发。

Laminated plastics packaging is growing at ~14%p.a in the UK, but these materials cannot be recycled as they are physically bonded and cannot be readily separated. They mostly consist of PET (the bulk of the laminated film) and one other polymer, usually PP or PE that is used as a very thin lining film for food contact and for lid sealing. A package may typically contain 2 to 10% PP/PE. PET is used to produce a wide range of products and demand for recovered PET is growing. There will be an increasing need to recover laminated PET to avoid landfill or incineration charges. The main challenge is to separate these physically bonded polymers. Our idea is to use solvent dissolution of the smaller fraction PE/PP greatly accelerated by use of ultrasound technology to leave clean, solid PET. We aim to process PET & license the technology to other PET recyclers. We may license a PET recycling systems manufacturer to build plants and sell licenses, enabling broad exploitation in the UK & EU.
