I've had several customers ask if our glassine bags are biodegradable, so I did a little research and here's the answer:
"Yes, glassine bags are biodegradable. Glassine is manufactured by a process called calendering. After pulping and drying sheets are passed through rollers so that the paper fibers are flattened out and facing in the same direction. To maximize the smoothness and thinness of the paper the glassine goes through this process several times.
Since glassine is made of only paper it is biodegradable.
