Biodegradable Duct Tape Film Bionly is a biodegradable bio-based polylactic acid (BOPLA) film produced by a step-by-step stretching method, which meets the printing and bonding needs of common sealing tapes. This film can be produced using original BOPP tape equipment, so customers can freely switch between the production of common BOPP tape and biodegradable BOPLA tape.
