Various bio-based biodegradable materials, films, packaging materials, and methods of manufacture are provided herein. For example, such components may include polyvinyl alcohol (PVA) based materials that include lactic acid (LA) such as in the form of polylactic acid (PLA). In this regard, the synthesis of various PVA based copolymer on which PLA oligomers are grafted as a result of synthesis from LA. The result is a PVA-g-PLA copolymer, which is distinct from PVA and PLA blends.
