Bioplastic packaging is made of plastics that are sourced from plants or other biological material. These include vegetable fats and oils, corn starch, straw, woodchips, sawdust, recycled food waste, etc. These sources are converted into polylactic acids (PLAs) to make bioplastic. It is considered safe and most commonly used in food packaging.
Biodegradable plastic is made of petroleum-based materials. However, it contains additives that allow the plastic to break more easily. Unlike bioplastics, biodegradable plastic packaging can leave behind toxic materials on decomposition.
