one • fıve is a biomaterials research, development and scale-up company, providing faster, affordable, tailored solutions with measurable environmental impact. 

As part of our recent developments for several customers we are looking to replace conventional heat sealant layers with renewable materials such as natural polymers. 

This call for proposal addresses the challenge of developing sustainable packaging solutions, specifically focusing on the intricate task of achieving heat-sealable paper coated with natural polymer, aiming for a heat seal strength of ≥3 N/15mm. 

The difficulty lies in the inherent complexities associated with obtaining natural polymers that meet the demanding heat seal strength requirements. This endeavor necessitates a deep understanding of natural polymers, paper, and material science, requiring expertise in extrusion coating, biopolymer extrusion, and sustainability assessments.  

The proposal must navigate the fine balance between processing parameters, ensuring that the extrusion coating on paper not only achieves the desired heat seal strength but also maintains crucial characteristics such as melt flow rate and adhesion to paper.  

The call recognizes the challenges inherent in working with natural polymers and underscores the need for innovation to overcome these hurdles. It seeks groundbreaking scalable solutions, emphasizing the significance of sustainable alternatives in the face of the packaging industry's evolving demands.
