MIRUM®
MIRUM® is an innovative, 100% bio-based leather alternative developed by Natural Fiber Welding.
MIRUM® delivers the appearance of premium coated leather with a natural, non-plasticky hand feel and no noticeable odour. Best suited for structured bags, small leather goods, belts, and accessories with top machine stitch. Due to its thickness and stiffness, it is not recommended for garments or designs requiring significant drape, heavy pleating, or high seam tension.
Composition: 100% USDA Certified BioPreferred® and completely plastic-free. Made from FSC-certified natural rubber, plant oils, agricultural by-products (including cork, coconut husk, and natural fibres), mineral fillers, and natural pigments.
Biodegradability: Fully biodegradable.
Petroleum Content: Free from petroleum-based PU and PVC.
Durability:ISO durability testing is not currently available. However, MIRUM® has demonstrated strong durability in commercial use and has been successfully adopted by multiple brands, supported by consistently positive long-term user feedback.
Water Resistance: Water-resistant.
Chemistry: Made using natural, non-toxic, petroleum-free pigments and ingredients.
Manufacturing: Produced in Illinois, USA; supplied from a warehouse in Germany.
Smell: Neutral, natural scent with no plasticky odour.
Technical Specification: Thickness 1.2 mm; backing: Lyocell jersey.
Colours / Finishes: Olive Pebbled, Cognac Pebbled, Cognac Plail & Black Plain.
Engraving: Suitable for laser engraving. Embossing and heat stamping may produce inconsistent results and are not generally recommended.
