Patents on Odor Reduction

Patent profile:

Unpleasant odor from plastics parts in particular recycled plastics is reduced/eliminated through a combined process including specific odor reducing additives and a skin-layer coextrusion or co injection moulding manufacturing process. 

Benefits for potential applications:

• Significant odor reduction without process slowdowns or high energy “stripping”
• Works on recycled plastics and bio‑filled materials (e.g., lignin, natural fibers)
• Tunable performance via additive type/dose and skin thickness; mono‑material designs enable recyclability
• Manufacturing‑ready: compatible with coextrusion, sandwich injection, in‑mold covering
• Meets demanding interior VOC/odor targets (automotive, appliances, consumer goods)
• Low additive loadings; maintains appearance and mechanical properties
