Food is paramount for the people, and food safety comes first.

Food is paramount for the people, and food safety comes first. As a leading local enterprise in Harbin specializing in the production of plastic packaging containers for food, Harbin Lianqing Plastic Packaging Container Co., Ltd. has steadfastly upheld the red line of food‑packaging safety for many years. The company has established an end-to‑to‑end quality‑control system that covers everything from raw‑material receipt and production oversight to finished‑product inspection, ensuring a steady supply to grain‑oil, sauce, dairy, and seasoning manufacturers across the province and earning its reputation as a reliable upstream supplier to Heilongjiang’s food industry.

Lianqing Plastics specializes in food-grade plastic buckets ranging from 1L to 25L, PET transparent packaging bottles, sauce‑sealing jars, and other products. All raw materials are sourced as virgin, food‑grade PP and HDPE, with no recycled or waste materials ever mixed in. In the raw‑material inspection area, quality‑control personnel conduct daily random sampling tests for heavy metals and plasticizers on plastic pellets. The production workshop employs partitioned, dust‑free management: all staff wear standardized cleanroom attire, and equipment undergoes scheduled disinfection to prevent cross‑contamination throughout the manufacturing process.

The finished‑product inspection process is equipped with a leak‑testing device, a low‑temperature impact tester, and a high‑temperature resistance tester. Each batch undergoes random sampling, with tests simulating long‑distance transportation, cold‑storage conditions, and high‑temperature filling. Nonconforming products are immediately shredded and remelted, ensuring they never reach the market. In response to the needs of the Northeast China grain and oil, pickled cabbage, and sauce industries, the company has developed thickened, freeze‑resistant packaging containers that are well suited for low‑temperature storage and transport during northern winters, addressing the common issues of cracking and leakage in standard plastic containers at subzero temperatures.

“Northeast China’s food companies have extremely stringent requirements for low‑temperature resistance and airtight sealing in their packaging. By establishing our base in Harbin, we can swiftly provide on‑site support to meet customized needs—producing samples on the same day and delivering within a short timeframe,” said the sales director. Currently, the company maintains long‑term partnerships with dozens of local food processors, leveraging its consistent product quality and localized service advantages to steadily expand its market share across the province. The company has obtained certification for manufacturing plastic containers intended for food use and has been recognized as a “Packaging Quality Integrity Enterprise” in the region, safeguarding the safety of Heilongjiang’s food industry through meticulous quality control.
