GOTHENBURG, Sweden, Nov. 24, 2021 (Press Release) -To maximize efficiency, PulPac’s Dry Molded Fiber uses an ‘in-line recycling’ system that may return any residual material with additives back into the process to be combined with additional input material.

During production tests to optimize barrier additives, it was shown that not only does the in-line recycling ensure more than 99% usage of fiber input materials, but the recirculation part of the process also reinforce barrier properties of the end-products. In essence, this has the potential to significantly increase production efficiency and conserve material consumption, while producing superior products compared to conventional fiber molding.

“This is a breakthrough with great potential to increase already highly competitive unit economics in DMF, by making better products with less input materials. It is an inspiring result by our R&D team for the technology as PulPac continues its industrialization of DMF” comments Sebastian Roos, Chief Technology Officer at PulPac AB

The results showed an increase and reinforcement in certain barrier properties with only limited impact on mechanical strength. This leads to increased production efficiency with lower energy and material usage. This important discovery is protected in a pending patent application and intellectual property belonging to PulPac AB.

About PulPac

PulPac provides the packaging industry with a groundbreaking manufacturing technology for low-cost, high-performance fiber-based packaging and single-use products. By pioneering the technology of cellulose molding PulPac enables their customers to replace single-use plastics with a sustainable and cost competitive alternative globally.

About Dry Molded Fiber

Dry Molded Fiber, invented and patented by PulPac, is a manufacturing technology designed for the circular economy – using renewable pulp and cellulose resources to produce low cost, high performance, fiber-based packaging, and single-use products. Dry Molded Fiber gives up to 80-90% lower CO2 footprint at similar cost as plastic. It is up to ten times as efficient as conventional fiber molding invented over 100 years ago. The dry process also saves massive amounts of valuable water resources. In addition, energy savings are significant - as the molded products need no drying.
