PluumoPlus provides a sustainable thermal mailer system for the life‑science and perishable‑goods sectors, using recycled feathers as the primary insulation to achieve higher R‑values and longer hold times than conventional expanded polystyrene. The pre‑assembled mailers feature modular designs for chilled, ambient, frozen, and deep‑frozen ranges and support interchangeable coolant options such as water‑based gels, dry ice, and phase‑change materials, reducing shipping costs and plastic waste while maintaining product integrity throughout the cold chain.

Problem
Temperature-sensitive products in the life‑science and perishable goods sectors rely on insulated packaging to maintain required temperatures during transport. Conventional insulation, such as expanded polystyrene, generates significant plastic waste and often provides limited thermal performance, leading to higher costs, product loss, and environmental impact.
Solution
PluumoPlus offers a sustainable thermal mailer system that uses recycled feathers as the primary insulating material. The feather‑based insulation delivers superior thermal protection across chilled, ambient, frozen, and deep‑frozen temperature ranges, extending hold times under demanding ISTA 7D profiles. The mailers are supplied pre‑assembled with interchangeable coolant options—including water‑based gels, dry ice, and phase‑change materials—allowing customers to select the optimal solution for their payload and temperature requirements. By replacing single‑use plastics with a circular, bio‑based material, PluumoPlus reduces both shipping costs and carbon footprint while ensuring product integrity throughout the cold‑chain journey.
Target Audience
Primary customers are pharmaceutical, biotech, and medical device manufacturers, as well as logistics providers handling temperature‑controlled shipments of vaccines, biologics, and other sensitive health products.
