Film blowing of pea, wheat and oat starch
Research Project, 2025 – 2026

A sustainable mix of starch, plasticizer, heat and mechanical energy can transform starch starch to a thermoformable bioplastic. RISE and Chalmers have previously cooperated on such thermoplastic potato starch and even been able the industrial technique film blowing which is difficult for native biopolymers. These films were strong and dissolved in water over time and are therefore good for applications as mulch films, packaging for oily additives (e.g. pesticides) and even laundry handling in hospitals. High amylose content was found to be advantageous and both wheat and pea starch should therefore be suitable for film blowing due to their high contents of amylose.
