Polypropylene is a semi-crystalline polymer, and as such it is naturally translucent or opaque. The introduction of additives, known as clarifying agents, makes PP highly transparent. The development of a high clarity PP has opened up many possibilities for the material to compete with other polymers and glass in packaging applications. This study provides a thorough assessment of the technology across the whole supply chain.
