The why
Pela. Leader and for phone cases. Flaxstic composite of flax shive plus plant-based biopolymer, 45% bio-based and 55% non-renewable. Compostable in industrial facilities per ASTM D6400 and EN 13432. Dermal chemistry profile differentiates from polycarbonate plus TPU peers: no BPA residual migration (NSF documents ~0.53 micrograms per day from polycarbonate consumer goods) and no petrochemical brominated flame retardant pathway (Bessa 2023 ES&T documents skin transfer from microplastics, sweat increases bioavailability). 10 plus hour daily skin contact window matters for both pathways; Pela's bio-polymer removes them. Materials disclosed as phthalate-free, BPA-free, cadmium-free, lead-free; PFAS not explicitly named. Certified B Corporation, Climate Neutral Certified, 1% for the Planet member.
