Engage with our high-barrier custom packaging engineered for strict market compliance and structural integrity.
Established in 2001, Jieyang Yuanzhong Printing Co., Ltd. has developed into a premier industrial entity in the flexible packaging and printing sector. Headquartered in the Jiedong District of Jieyang City, Guangdong Province, our corporation possesses over two decades of technical expertise. We manufacture specialized, high-barrier plastic packaging bags and laminated roll stocks, delivering custom flexible packaging engineered to meet the needs of global consumer packaged goods (CPG) companies.
Our industrial production capabilities are driven by state-of-the-art machinery. We operate fully automated Japanese Komori printing lines, solventless high-speed lamination machines, and computer-controlled slitting and bag-making lines. Together, these technological assets yield a monthly output exceeding 240 metric tons. This extensive manufacturing infrastructure ensures short production cycles and consistent quality control, positioning us as a reliable partner in the global packaging supply chain.
Our custom packaging systems serve customers across North America, the European Union, Southeast Asia, and South America. By using advanced co-extrusion technology, multi-layer functional laminations, and diverse seal configurations, we ensure that every packaging solution provides optimal barrier properties, structural stability, and strong brand presence on store shelves.
Modern flexible packaging requires precise control of environmental exposure. Hermetic sealing protects volatile ingredients, limits lipid oxidation, and prevents moisture entry. Achieving a reliable seal depends on selecting the right combination of polymers, managing the seal temperature range, and ensuring consistent machine setup. At Jieyang Yuanzhong Printing, we engineer distinct laminated film structures tailored to target application requirements:
Aluminum foil barriers provide excellent resistance to oxygen, light, and water vapor transmission (nearly 0 WVTR). Ideal for sensitive products like powdered milk, protein powders, and active-ingredient pet formulas.
Offering a balance of robust barrier performance and cost-effectiveness. This combination provides excellent light blocking and puncture resistance, making it ideal for snacks, chips, and dry food ingredients.
Single-polymer structures (such as Mono-PE laminates) and biodegradable resins match the barrier performance of traditional polymers while helping brands meet regulatory requirements for circular packaging.
Our sealing technology controls three critical thermal sealing variables: temperature, pressure, and dwell time. This prevents micro-pinholes along the seal seams, protecting foods from premature spoilage and ensuring that liquid packaging remains leak-proof under pressure.
We use high-definition gravure printing and solventless lamination to deliver consistent mechanical properties and visual clarity.
Gravure Printing technology plays an important role in high-volume packaging production. Gravure printing uses engraved cylinders to transfer ink directly onto the substrate. This method is preferred for long-run packaging because of its thick ink transfer, deep color saturation, durability, and reliable print consistency at high speeds.
Selling products in international markets requires compliance with local food safety laws and packaging regulations. We work closely with our partners to ensure that all packaging structures meet local requirements in Europe, the United States, and other regions.
Our raw polymer films, barrier coatings, and pigments are tested to ensure compliance with global standards, including FDA regulations for direct food contact and EU directives (EC No 1935/2004) governing plastic packaging materials. Additionally, our factory maintains rigorous quality management systems to monitor contamination risk, traceability, and material integrity at every stage of the manufacturing process.
To support overseas partners, we offer localized services including:
China remains a leading manufacturing hub for flexible packaging. Strategic partnerships with Chinese producers like Jieyang Yuanzhong Printing offer several key advantages for global brands:
Direct access to regional petrochemical clusters and polymer producers simplifies sourcing. It allows us to secure raw materials like BOPA, BOPET, and high-clarity cast PE films at competitive rates.
Automated extrusion, printing, and slitting lines reduce manual handling. This level of automation keeps unit costs low while ensuring consistent compliance with narrow dimensional tolerances.
Equipped with multi-cylinder setup systems, our factory can quickly transition production lines. This allows us to scale output from low-volume diagnostic runs to million-unit commercial orders.
Our facility in Jieyang City, Guangdong Province, is located close to key shipping ports in Shenzhen and Guangzhou. This location provides convenient access to maritime shipping routes, helping to lower international freight costs and shorten transit times for overseas buyers.
Different product markets place unique demands on flexible packaging seals. Our designs are customized to address these specific performance requirements:
We participate in packaging shows worldwide and partner with recognized global consumer brands.
Critical answers to help packaging engineers and procurement teams select the right bag configurations.
Heat seal integrity depends on three primary variables: seal temperature, jaw pressure, and dwell time. In addition, the choice of sealant resins, such as metallocene-catalyzed linear low-density polyethylene (mLLDPE), helps the seal withstand contamination from dust or oils during the filling process.
We source raw polymers that comply with FDA and EU regulations for direct food contact. Our manufacturing facilities follow strict hygiene protocols, and we provide technical data sheets (TDS) and compliance certificates to support customs clearance in destination markets.
Mono-material laminations, such as structures made entirely of polyethylene (PE), are easier to recycle than traditional multi-material films. They align with circular economy goals by allowing the packaging to be collected and recycled within existing waste streams.
Yes. Our spout pouches, including large format options up to 5L, are manufactured with chemically resistant inner liners. The spouts are heat-welded directly to the film layers, ensuring they do not leak or affect the taste and quality of acidic or liquid foods.
