PLIITH's Modified Materials Division is mainly engaged in the modification research, application development, production, and sales of biobased and biodegradable materials, dedicated to providing customers with high-performance and functional green environmental protection materials solutions.
Polylactic Acid (PLA): Derived from renewable biomass materials and completely degradable into water and CO2, fully meeting the requirements of green, low-carbon, sustainable economic development. However, PLA has inherent limitations such as brittleness, low melt strength, poor heat resistance, and uncontrollable degradation rate, which greatly limit its performance and market competitiveness. PLIITH's Modified Materials Division has thoroughly overcome these limitations, effectively expanding PLA applications. Currently, Kinpoly uses PLA, PBS, PBAT, and PHAs as raw materials and has developed a series of product solutions, primarily including straws, cutlery, films/membranes, sheets/blister packaging, 3D printing, and injection-molded products, all meeting the biodegradation requirements of ASTM D6400, EN13432, and GB/T19277.
