Behind every reliable flexible packaging product is a manufacturing process that requires careful coordination between printing, lamination, slitting, bag making, and quality inspection. For packaging buyers, understanding a manufacturer's production capabilities is an important part of evaluating a potential long-term supplier.

At PACK EXPO International 2026, held from October 18 to 21 at McCormick Place in Chicago, Heshan Zhongxing Laminated Packing Co., Ltd. presented its manufacturing experience and quality management capabilities at West Building, Booth W-50060.

Established in 1993, Zhongxing has more than 30 years of experience in plastic flexible packaging manufacturing. The company continues to focus on production efficiency, product consistency, and quality control to meet the requirements of customers across different industries.

A Manufacturing Facility Supporting Multiple Packaging Processes

Zhongxing operates a workshop covering approximately 20,000 square meters, with production equipment supporting the major stages of flexible packaging manufacturing.

Its production facilities include four production lines, four printing machines, four automatic inspection machines, five lamination machines, five slitting machines, and 20 bag-making machines.

These facilities support the production of different flexible packaging formats, including stand-up pouches, flat-bottom bags, zipper pouches, Spout Pouches, three-side seal bags, and customized packaging roll films.

Each manufacturing stage plays an important role in the final product.

Printing determines the appearance and accuracy of the packaging design. Lamination combines different film layers to achieve the required material structure and functional properties. Slitting prepares the laminated film for subsequent production, while bag making forms the final pouch according to the specified dimensions and construction.

Coordinating these processes helps ensure that packaging products meet their intended specifications.

Quality Control Throughout Production

Packaging quality cannot be determined by appearance alone. Material performance, mechanical strength, sealing properties, and barrier characteristics can all influence the reliability of the finished product.

Zhongxing holds ISO 9001:2015 and BRC certifications and has an independent laboratory equipped with testing instruments for product evaluation.

Its testing capabilities cover several important areas:

• Material and Chemical Testing: Gas chromatography and other laboratory equipment support material-related evaluations.

• Mechanical Performance: Tensile testing and film impact testing help assess material strength and durability.

• Barrier Performance: WVTR and OTR testing equipment evaluates moisture vapor and oxygen transmission.

• Surface Properties: Coefficient of friction testing helps assess film surface characteristics.

• Product Identification: Barcode scanning supports packaging identification and verification.

• Heat Resistance: Retort testing equipment supports evaluations of packaging designed for heat-processing applications.

These testing capabilities provide important technical support for evaluating materials and finished packaging products.

Supporting Different Packaging Applications

Different industries place different demands on packaging quality. Food packaging may require suitable barrier properties and material safety considerations, while pet food packaging may need durable structures and reliable resealing features.

Coffee packaging may require specific barrier structures and degassing valves. Liquid packaging may require suitable spout and sealing designs.

Zhongxing's manufacturing capabilities cover a broad range of these applications, allowing the company to provide different material combinations, pouch structures, and functional options.

Building Long-Term Manufacturing Partnerships

PACK EXPO International 2026 gave Zhongxing an opportunity to introduce its production capabilities and quality management approach to international packaging professionals.

For Zhongxing, manufacturing strength is not simply about the number of machines or production lines. It also involves understanding product requirements, controlling each processing stage, and maintaining communication throughout the manufacturing process.

Moving forward, Zhongxing will continue improving its production and quality management systems while supporting customers with customized flexible packaging products.

With more than 30 years of industry experience, the company looks forward to establishing stable manufacturing partnerships with customers worldwide.
