The fully biodegradable seedling bag is a specialized seedling container developed by Zaozhuang Tianyao Starch Technology Co., Ltd., based on a fully biodegradable material system of PBAT, PLA, and corn starch, and manufactured using the blown film molding process. The product is specially designed for nursery scenarios such as trees, fruits and vegetables, and flowers, providing a good root growth environment during the seedling period. No manual bag removal is required during transplantation; it can be directly buried in the soil, and the bag will naturally degrade into carbon dioxide and water, while simultaneously providing nutrients for the seedlings, achieving 'bagged transplantation, zero residue, labor-saving and effort-saving.'
