STRONG - sustainable thermo-resistant resilient oxygen-barrier next-gen packaging
Innovative biopolymer-based packaging offering compostable solutions with enhanced thermal and mechanical performance, oxygen barrier properties, and extended shelf life for high-acid, high-moisture ready-to-eat products.
Overview
STRONG packaging represents a breakthrough in sustainable packaging by utilizing biopolymer-based materials that are entirely compostable. Developed by EggPlant under the Rimeloop trademark, this solution addresses the limitations of traditional bioplastics with advanced formulations that ensure robust performance. The packaging is designed for high-acid, high-moisture ready-to-eat (RTE) products, offering extended ambient shelf life with excellent thermal and mechanical properties.
Technical specifications
The STRONG packaging solution leverages PHA-based formulas modified with green additives and blended with other biopolymers. Key components include PHB for high crystallinity and oxygen barrier, PBAT for flexibility and impact resistance, and nanoclay for reducing gas and moisture permeability. The use of oxygen scavengers and antioxidants further enhances the packaging's ability to maintain product integrity. The proposed solutions include monolayer or multilayer rigid/semirigid packaging, with potential development for flexible packaging.
Technology readiness level
Currently at Technology Readiness Level 5, STRONG packaging has undergone significant lab-scale testing and is poised for pilot-scale production. This includes evaluations of barrier properties, thermo-mechanical performance, and simulated product testing to ensure durability and effectiveness. EggPlant is actively seeking partnerships for sponsored research to advance development towards industrial-scale testing and commercialization.
About EggPlant
EggPlant is an Italian startup that specializes in the production of advanced bioplastic-based solutions through a proprietary, zero-waste technology. By utilizing wastewater from the agri-food industry as a raw material, the company produces polyhydroxybutyrate (PHB), a fully bio-derived and biodegradable bioplastic. This process is built on principles of circular economy and biomimicry, effectively repurposing industrial waste into high-performance materials. Beyond the core bioplastic production, the company has developed integrated technology platforms that include conductive bioplastics, active packaging, and applications for sectors such as electronics, biomedicine, agriculture, and aerospace.
This technology addresses critical environmental challenges by simultaneously mitigating issues related to wastewater disposal and reducing reliance on traditional hydrocarbon-based plastics. By transforming waste into a valuable resource, EggPlant supports industries in achieving greater economic and environmental sustainability. The company, headquartered in Polignano a Mare, Puglia, operates with the vision of eliminating the conventional concept of waste, aiming to contribute to a balanced and responsible development model for both industry and society.
