Ningbo Zhonglong Plastic Cement Co., Ltd

Ningbo Zhonglong Plastic Cement Co., Ltd. is a long-standing supplier in China, having been established in 1998 — which gives them experience and stability compared to newer players. Their core product, vacuum storage bags, is a common item in food and industrial packaging, making them a familiar choice for buyers looking for reliable, standard packaging solutions. Being headquartered in Ningbo, a major industrial city in eastern China, they benefit from strong logistics and access to raw material suppliers. However, none of their key verification details — work email, phone number, or business documents — have been confirmed. This lack of verification raises a red flag for buyers who need to ensure legitimacy before placing large orders. Without verified contact or documents, it's harder to trust their responsiveness or ability to meet specific quality or delivery needs. Buyers should request additional proof before engaging in serious business.
