Biaxially oriented bio-based polyester thin films and laminates for thermal transfer printing

摘要

A bio-based polyester thin film substrate for thermal transfer printing ribbon. The bio-based polyester thermal transfer ribbon substrate film has a radiocarbon content of at least 12 pMC. The film exhibits excellent uniformity, handling, and processability, substantially equivalent to petroleum-based counterparts, while being derived wholly or partly from non-petroleum sources.
