Silk
Natural fiber
Low plastic. Protein fiber. Zero plastic.
What silk is
Silk is a protein fiber spun by silkworms — no plastic, no petroleum, fully biodegradable. It remains the benchmark for fine, strong, temperature-regulating fabric.
Watch for imitations: most “satin” and “silky” products sold today are polyester. Satin names a weave, not a fiber; only the composition line tells you which one you’re buying.
How Plastfri scores it
Silk scores 0/100. A “silk-feel” polyester blouse scores as polyester — the score follows the fibers, not the adjective.
The same weight applies everywhere: a product's score is the percentage-weighted plastic share of its listed fiber composition, and every weight is public.
