Self Removing Polymer Packaging with Active Function

我们的愿景是开发自拆卸包装，在其从传统废流中清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，目前使用多层阻隔膜来保护高度敏感的水溶性膜，这些多层阻隔膜含有混合聚合物，因此这些聚合物很难回收利用，属于7类“其他”。聚乙烯醇是一种符合CEN 13432标准的水溶性无毒生物降解聚合物。在薄膜和注射成型形式中，它主要用于洗涤剂和农用化学剂量，聚合物溶解在水中释放活性成分。它具有吸湿性，在50RH以上的条件下容易受到大气吸湿性的影响。因此，需要昂贵的防护包装来保持其物理性能，这对于在包装腐蚀性洗涤剂时保持儿童安全法规非常重要。我们的第一个关键目标是设计和开发一种新的洗涤剂格式，通过用适合注塑成型的新的吸湿性较低的PVOH配方取代浇注PVOH薄膜来消除对二次阻隔包装的要求。为了儿童安全和产品释放，需要在胶囊周围开发配方，在较短的生态洗涤周期中没有观察到残留，并耐大气潮湿。我们的第二个关键创新目标是开发二次包装，以保护主要包装产品免受大气湿度的影响，其形式为水溶性容器，在洗碗机中清空时会溶解。这个容器将包含一种在溶解过程中释放的清洗剂，为聚合物添加功能，该聚合物将被封装在聚合物中或包装内的一个独立的防篡改隔间中。聚合物产品进入水道最近由David Attenborough爵士(蓝色星球和塑料海洋)强调。PVOH在自然环境中会迅速生物降解，不会形成微珠或塑料残留物，对野生动物造成危害。

"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."
