Established in 2001, Jieyang Yuanzhong Printing Co., Ltd. has stood as a pioneer and definitive leader in the high-barrier flexible packaging industry for over two decades. Located in the Jiedong District of Jieyang City, Guangdong Province, China, our advanced facility has consistently supplied custom-tailored flexible packaging solutions to global clients across food, cosmetic, pharmaceutical, and consumer goods sectors.
Yuanzhong Pack specializes in high-fidelity packaging decoration printing, along with the precise manufacturing and structural sealing processing of plastic packaging bags. We pride ourselves on operating imported, state-of-the-art machinery including fully automatic production lines sourced from Japan. Our integration of the Japan Komori automatic offset printing systems alongside high-speed rotogravure production complexes ensures a massive, reliable production volume exceeding 240 tons monthly.
By keeping all manufacturing processes in-house—ranging from custom material lamination (solventless composites) to custom ziplock and slide-seal installations—we offer an end-to-end Original Design Manufacturing (ODM) framework. Our rigorous quality control protocols and bespoke customer-centric design services guarantee that each roll film and stand-up seal pouch is engineered to fulfill precise barrier, shelf-life, and functional closure specifications.
As supply chain volatility grows and environmental regulations tighten, global procurement managers demand highly engineered, resealable flexible packaging systems that deliver high performance with reduced carbon footprints.
Procurement executives must coordinate supply chains across various markets while ensuring strict compliance with local regulations. Raw material variability, moisture barrier requirements, and shipping durations make it critical to partner with a reliable ODM factory that handles precise multi-layer film extrusion and customized mechanical seals.
The packaging's seal is its primary point of failure. Low-quality seals lead to burst bags, product spoilage, and brand damage. Our heat-sealing technologies and custom zipper integration ensure high seal strength and peel-force resistance, keeping volatile compounds locked in and external contaminants out.
The global packaging market is moving rapidly from multi-layer mixed plastics toward mono-material recyclable structures (such as all-PE laminates) and biodegradable options. Yuanzhong Pack helps global brands transition smoothly with sustainable materials that maintain optimal barrier properties.
Our rotogravure printing technology plays an essential role in flexible packaging manufacturing. It features thick ink laydowns, bright colors, high color saturation, long plate life, and high-speed stability.
Rotogravure printing up to 10 colors for optimal clarity.
Multi-layer dry and solventless lamination for barrier protection.
High-speed precision slitting to customize roll widths.
Pouch forming, side-gusseting, and zipper/seal integration.
Batch testing, vacuum seal inspection, and carton packaging.
To produce reliable plastic bags with functional resealable systems, we combine various material layers to meet specific barrier needs. This design protects your products from oxygen, moisture, and ultraviolet light:
PET / BOPP: High print resolution, heat-resistant barrier, strong mechanical protection.
AL / VMPET / Nylon: Complete light block, minimal oxygen transmission rate (OTR), and low moisture vapor transmission rate (WVTR).
LDPE / CPP: Food-safe, low-temperature thermal bonding, high puncture resistance.
How Yuanzhong Pack is adapting to the next generation of flexible, sustainable, and smart retail packaging systems.
Laminating PET and PE together makes traditional films difficult to recycle. Our engineering pipeline is transitioning clients toward mono-material (All-PE or All-PP) barrier packaging. These configurations are fully recyclable within existing municipal recycling systems, keeping plastic out of landfills.
Future designs focus on ergonomic ziplock closures, including slider zippers for large volumes, press-to-close zippers for dry products, and powder-resistant zippers that seal reliably even when particulate matter is present in the channel.
Using printed electronics, RFID, and high-density QR matrices directly on the package. This enables B2B buyers to verify product authenticity, track manufacturing history, and monitor temperature conditions from factory gate to final warehouse.
Over the past decade, we have traveled to more than 10 countries to engage with packaging distributors, research institutions, and clients.
Partnering with over 20 global brands: a testament to our commitment to quality, performance, and reliability.
Meeting the strict requirements of international food-grade safety, chemical transport regulations, and regional compliance.
Our manufacturing materials are 100% FDA-approved and comply with EU directive 10/2011 for plastic materials intended to come into contact with food. This makes our packaging ideal for sensitive applications like baby milk formula and specialized pet treats.
Each batch of our plastic bags with seals undergoes strict laboratory testing, including tensile strength verification, burst testing, leak testing for liquid applications, and gas chromatograph verification for residual solvents.
We provide end-to-end logistics solutions, export documentation, customs brokerage clearance, and port routing. We offer FOB, CIF, DDP, and DAP terms to make shipping simple and efficient for our B2B customers.
