This document discusses Quality By Design (QBD) approaches for packaging development. It begins by defining QBD and its key components, including Critical Quality Attributes (CQAs), Critical Process Parameters (CPPs), design space, and Quality Target Product Profile (QTPP). It emphasizes understanding how material attributes and process parameters impact CQAs. It also discusses identifying sources of variability and continuing monitoring throughout a product's lifecycle. The document then provides details on each step of QBD for packaging development, including concept development, product development, and industrialization. Concept development involves establishing QTPPs and CQAs based on customer needs and performing design experiments and analysis.
