Edible lubricant-infused surfaces for complete container evacuation
Innovative PET surfaces retain edible lubricants, enabling effortless emptying of viscous contents. This technology adapts nanowrinkled Teflon surface principles to PET, ensuring recyclability and safety.
Overview
The proposed solution involves the creation of micro- and nano-structured PET surfaces that can hold an edible lubricant layer, significantly enhancing the ease of emptying viscous contents from containers. This technology uses principles previously applied to Teflon surfaces, aiming to replicate the benefits of lubricant infusion within recyclable PET materials. The innovation promises to improve product evacuation, reduce waste, and maintain the safety and recyclability of packaging.
Technical specifications
Key features:
- Micro- and nano-structured surfaces: These are engineered to hold lubricants securely, ensuring long-term slip properties.
- Edible lubricants: The use of food-grade oils ensures safety and compliance with food packaging standards.
- Scalable fabrication process: Techniques are compatible with current PET bottle manufacturing, allowing for easy integration into existing production lines.
- Performance assessment: Surface quality is evaluated using SEM and AFM, while liquid evacuation efficiency is tested through wetting property measurements.
Technology readiness level
This technology is at TRL 3, indicating that it is in the experimental proof-of-concept stage. Ongoing research focuses on optimizing surface structuring and lubricant deposition, with plans for further validation and testing in collaboration with industry partners.
