As a plastic cup manufacturing enterprise, we always place food safety and quality control at the core, strictly follow the national food contact material safety standards and international authoritative certification requirements, and build a full chain quality supervision system from raw material selection to finished product delivery. In terms of raw material selection, enterprises abandon low-priced and low-quality materials, and prefer food grade PP (polypropylene), biodegradable PLA and other safe and environmentally friendly materials. Among them, PP material can withstand temperatures up to 120 ℃, has excellent impact resistance and corrosion resistance, meets FDA food contact safety certification, and eliminates safety hazards from the source; In the production process, high-precision injection molding equipment is introduced, and mold flow analysis technology is used to optimize the melt flow path. The mold processing tolerance is controlled within 0.05mm, and multiple rigorous tests such as underwater pressure sealing testing and cold and hot cycle testing are carried out to ensure that the factory qualification rate of each water cup is not less than 99.5%, completely solving consumer pain points such as leakage and material precipitation.
