Henan Hengrong New Materials Co., Ltd., based in Kaifeng, specializes in customized food-grade plastic packaging. Supported by mature manufacturing processes and rigorous quality control, the company delivers safe, reliable packaging solutions for the food industry.

Custom Packaging Starts with Agility

Kaifeng has long been known for its food culture. Hengrong’s contribution is helping those products stand out with packaging designed to match today’s market. Inside Hengrong’s production facility, 24 Haitian injection molding machines run around the clock, producing a wide range of customized food packaging. „Almost everything we produce is custom-made. “ says Chairman Kong Jian. Instead of relying on the same mold for years, Hengrong refreshes most of its packaging every one to two years to keep pace with changing products and consumer trends.

This commitment to customization means longer development cycles and more complex production, but it also helps customers‘ products stand out on the shelf—even entering leading retail chains such as Pangdonglai. This high-mix production environment with frequent changeovers places exceptional demands on machine responsiveness and long-term reliability, making Haitian the natural choice.

Transforming Production with In-Mold Labeling

Hengrong’s manufacturing evolution can be traced through something as simple as a label.

The company has continuously upgraded its production process—from unlabelled packaging, to heat transfer printing, and now to in-mold labeling (IML). By integrating the label directly into the molding process, IML reduces manual operations while improving durability, appearance, product consistency and overall production efficiency. „Although the initial investment is higher, the overall cost for our customers is actually lower,“ Kong explains.

Reliable IML production requires exceptional precision, while Haitian’s high-speed injection molding machines deliver the positioning accuracy and repeatability to keep the process stable.

Quality extends beyond the molding process. Hengrong’s new facility features a 4,500 m² clean workshop and works closely with leading mold  manufacturers to maintain high food safety and quality standard.

Reliability That Stands the Test of Time

Hengrong’s partnership with Haitian began in 2017. After comparing several domestic and international brands during product development, the company found Haitian consistently offered the best long-term stability. Today, Hengrong operates 24 Haitian injection molding machines ranging from 200 to 460 tons, including the latest thin-wall solution introduced during the expansion of its new production facility. According to Kong, the first batch of Haitian machines has been running reliably for six to seven years, while their energy efficiency continues to deliver measurable operating savings.

During the company’s relocation and expansion, Haitian equipment ensured uninterrupted production. Hengrong has also adopted Haitian Smart Solutions‘ centralized material feeding system, reducing labor while improving efficiency and workplace cleanliness.

A Partnership Beyond Machines

What began with injection molding machines has grown into a broader manufacturing partnership. From equipment to feeding system, Hengrong and Haitian continue to deepen their collaboration through system-level solutions. This experience highlights a simple truth: in fast-changing, highly customized production, long-term reliability is not an advantage—it’s a necessity. Together, Hengrong and Haitian are building a smarter, more efficient and more sustainable future for food packaging manufacturing.
