This research aims to understand why consumers miss-sort plastic food packaging and to what extent the design affordance of packaging can influence consumer sorting behavior. A photo-based observation study and semi-structured interviews were used to gain a deeper understanding of the miss-sorting behavior and how it could be affected by design affordance. This explorative study suggested that the packaging form, size, durability, haptic aspects, and visual communicative properties influence how consumers perceive the value of packaging. This is important, because packaging with low attributed values are not considered worth recycling or correctly sorted and are more likely to be miss-sorted. Hence, a well-afforded food packaging design is expected to improve how consumers perceive the value of packaging and to consequently improve sorting behavior.

这项研究旨在了解为什么消费者会误选塑料食品包装，以及包装的设计可供性在多大程度上影响消费者的分类行为。基于照片的观察研究和半结构化访谈被用来更深入地了解错误排序行为以及它如何受到设计可供性的影响。这项探索性研究表明，包装形式、尺寸、耐用性、触觉方面和视觉交流特性会影响消费者对包装价值的看法。这很重要，因为具有低属性值的包装不被认为值得回收或正确分类，并且更有可能被错误分类。因此，
