Self Removing Polymer Packaging with Active Function

“我们的愿景是开发自移除包装，在从传统废物流中移除的过程中执行二次清洁功能，从而鼓励客户参与这项技术。该项目针对洗涤剂行业，多层阻隔膜目前用于保护高度敏感的水溶性膜，这些多层阻挡膜含有混合聚合物，因此这些聚合物难以再循环，是可再循环类别7““其它”"。是符合CEN 13432的水溶性无毒生物可降解聚合物。在其薄膜和注塑形式中，它主要用于洗涤剂和农用化学品配料，其中聚合物溶解在水中以释放活性成分。由于吸湿，在超过50 RH的条件下容易吸收大气水分。因此，需要昂贵的保护性包装来保持其物理性能，这对于在密封碱性洗涤剂时保持儿童安全法规非常重要。我们的首要目标是设计和开发一种新的洗涤剂形式，通过使用适合注塑成型的新型吸湿性较低的PVOH配方替代PVOH流延膜，消除对二级屏障包装的要求。我们的配方需要围绕胶囊强度进行开发，以确保儿童安全和产品释放，在短生态洗涤周期内不会观察到残留物，并能抵抗大气水分。我们的第二个关键创新目标是开发二级包装，以保护初级包装产品免受大气水分的影响，其形式为水溶性容器，在洗碗机中清空时即可溶解。该容器将包含在溶解过程中释放的清洁剂，为聚合物添加功能，该聚合物将被封装在聚合物中或封装在包装内的自包含防篡改隔室中。大卫阿滕伯勒爵士最近强调了进入水道的聚合物产品（蓝色星球和塑料海洋）。PVOH在自然环境中可迅速生物降解，不会形成对野生动物造成危害的微珠或塑料残留物。"

"Our vision is to develop self removing packaging to perform a secondary cleaning function during its removal from the traditional waste stream thus encouraging customer engagement of this technology.This project is aimed at the detergent sector, multilayer barrier films are currently used to protect highly sensitive water soluble films, these multilayer barrier films contain mixed polymers therefore these are difficult to recycle being recycling class 7 ""other"".Polyvinyl Alcohol (PVOH) is a water soluble nontoxic biodegradable polymer which conforms to CEN 13432\. In its film and injection moulded format it is predominantly used for detergent and Agrichemical dosing, where the polymer dissolves in water to release the active components.Being Hygroscopic it is susceptible to atmospheric moisture uptake in conditions over 50RH. Therefore, expensive protective packaging is required to maintain its physical properties, this is important to maintain child safety regulations when caustic detergents are encapsulated.Our first key objective is to to design and develop a new detergent format which eliminates the requirement for secondary barrier packaging by the substitution of cast PVOH film with a new less hygroscopic PVOH formulation suitable for injection moulding. Formulation will need to be developed surrounding capsule strength for child safety and product release with no residue observed during a short eco wash cycle and be resistant to atmospheric moisture.Our second key innovative objective is to develop secondary packaging to protect the primary packaged product against atmospheric moisture in the form of a water soluble container to be dissolved when empty in a dishwasher. This container will contain a cleaning agent to be released during dissolution, adding function to the polymer which will either be encapsulated in the polymer or in a self contained tamper proof compartment within the packaging.Polymer products entering water courses has been recently highlighted by Sir David Attenborough (Blue Planet and A Plastic Ocean). PVOH is quickly biodegraded in the natural environment and will not form microbeads or plastic residue causing hazards to wildlife."
