Next generation recyclable lightweight polymer packaging
Introducing a patented Melt-Mastication process for semi-crystalline polymers, enhancing mechanical properties and recyclability. This innovation doubles stiffness and strength without reinforcement, reducing polymer usage and packaging weight while improving barrier properties.
Overview
The University of Massachusetts Lowell presents an innovative solution in the form of a patented Melt-Mastication process, designed to enhance the properties of semi-crystalline polymers used in packaging. This process significantly improves mechanical stiffness, strength, and toughness by inducing flow-induced crystallization within a chaotic flow field. As a result, polymer usage can be reduced by half while maintaining structural integrity, offering a sustainable alternative for producing fully recyclable packaging.
Technical specifications
- Melt-Mastication Process: Utilizes a patented chaotic flow field to process polymers between their melt and crystalline temperatures.
- Material Enhancement: Doubles stiffness and strength without reinforcement, thanks to increased crystallinity and unique granular morphology.
- Compatibility: Effective for various semi-crystalline polymers, including iPP and HDPE.
- Barrier Properties: Enhanced barrier capabilities, improving the protective performance of packaging materials.
- Sustainability: Reduces polymer consumption and weight, maintaining recyclability.
Technology readiness level
This solution is currently at TRL 5, having undergone validation in a laboratory setting. Further development is ongoing to optimize processing conditions and expand its applicability to a broader range of polymers.
