Phabuilder's world premiere new products include: pure PHA(polyhydroxyalkanoate) material for straw/knife/fork/spoon/coating and trimer PHA aqueous latex. All of them are pure PHA materials that do not contain other polymers such as PLA/PBAT/PBS, with 100% biobased, home/industrial composting, and marine/soil/river water biodegradability. The biodegradation rate of PHA is more than 98% and degradation products without microplastics and other harmful substances. The trimer PHA has properties of high transparency (T≥95%), high elongation (breaking elongation≥500%), and high barrier properties (water oxygen barrier<5/ 24 h). These advantages allow PHA products to meet the end-user experience while promoting the packaging field to low-carbon and sustainable development.
