Designing future water soluble packaging

Lead Research Organisation: University of Birmingham
Department Name: Chemical Engineering


Because of the multiple technical advantages it possesses, e.g. minimal environmental impact, easy processability, and great sustainability, poly(vinyl alcohol) (PVA) is widely used as water soluble packaging materials for a diverse range of formulated products. However, upon exposure to highly concentration surfactants, the small molecules (surfactants + plasticisers) will migrate within and across the PVA film, of which the diffusion kinetics is currently being investigated through an EPSRC funded project (Molecular Migration in Complex Matrices: Towards Predictive Design of Structured Products, EP/P007864/1). The focus of this research consortium is to fundamentally understand and consequently control the migration characteristics of additives in formulated products, including packaging, food, or paint.
An equally important aspect that is required for closing the loop of designing future water soluble packaging materials is to understand the dissolution process of PVA film upon exposure to liquid. This process determines the longevity of additives included, as well the shelf life of the products.
