New DTF films made from polylactic acid (PLA), a bioplastic derived from corn starch, are now commercially available and can biodegrade within 6 months in industrial composting facilities. Traditional DTF films are made from PET, which is recyclable but not biodegradable, contributing to plastic waste. The PLA films offer comparable print quality and release properties to PET, with the added benefit of a lower carbon footprint during production. Early adopters report that PLA films perform well with both water‑based and solvent‑based DTF inks, and the powder adhesion is consistent. しかし, the PLA films are currently more expensive than PET, limiting adoption to eco‑conscious customers and premium applications.
For users of Xinflying DTF printers, switching to PLA films requires no hardware changes, but may need minor adjustments to heat press temperature and dwell time, as PLA has a lower melting point than PET. Several major consumables suppliers have announced plans to offer PLA‑based DTF films by the end of 2026, and prices are expected to decrease as production scales up. The development is part of a broader industry trend toward sustainable consumables, driven by brand requirements and regulatory pressure. As more municipalities ban single‑use plastics, the demand for biodegradable alternatives in printing will likely increase, making PLA films an important option for forward‑looking print shops.
