Fully biodegradable PLA stic products are materials extracted from sugar-containing PLA nts such as corn, sugar cane, and cassava PLA , made using a unique process, does not contain toxic and harmful chemicals. Fully biodegradable PLA stic products made of polylactic acid, a PLA nt extract such as corn, inherit the non-toxic and harmless quality of PLA nts, and are healthy, safe and environmentally friendly.Ordinary PLA stic products are made of various PLA stics as the main raw materials, and are made by adding different additives according to special needs. Some PLA stic monomers such as styrene are toxic, and some additives such as phthalates, polycyclic aromatic hydrocarbons, etc. Classes are harmful, and pigments often contain harmful heavy metals such as antimony.After ordinary PLA stic products are used and discarded, it takes hundreds of years to degrade. The formed PLA stic waste and micro PLA stics have caused serious harm to land, marine organisms and the ecological environment.After the fully biodegradable PLA stic products are used and landfilled, they can be eaten by microorganisms and absorb energy, and the rest will be converted into carbon dioxide and water to be excreted, realizing zero-pollution organic return, and can be used as organic fertilizers.
