Engineered with multilayer co-extrusion technology for superior preservation, safety, and shelf-life enhancement.
Jieyang Yuanzhong Printing Co., Ltd. stands as a premier leader in the global packaging printing industry. Established as a private enterprise in 2001 in the Jiedong District of Jieyang City, Guangdong Province, China, we possess over two decades of sophisticated printing experience. We relentlessly strive for excellence, providing top-tier products designed to fulfill the complex and diverse packaging requirements of modern commercial buyers.
Under our dedicated packaging brand, Yuanzhong Pack, we specialize in high-definition packaging decoration printing, alongside the design, extrusion, and processing of custom plastic packaging bags. To uphold our rigorous standards of production speed and quality, we operate state-of-the-art facilities equipped with advanced imported hardware, such as the fully automatic Japanese Komori printing lines. This industry-grade setup enables a high-volume monthly output of over 240 tons, guaranteeing short lead times and continuous supply security for our global partners.
"Our commitment to high-precision customization is what differentiates Yuanzhong Pack in the competitive landscape. With direct factory access and customized lamination technology, we cater to over 30 countries globally, offering bespoke packaging that drives brand growth."
A rigorous five-stage production cycle optimizing durability, barrier properties, and color accuracy.
In modern industrial applications, gravure printing holds a foundational position in manufacturing flexible plastic packaging due to its exceptional technical advantages. These include a high-thickness ink layer, brilliant colors, superior saturation, exceptional plate durability for long runs, and stable, high-speed output. By utilizing composite multi-layer extrusion (PET, AL, PE, VMPET, CPP, Kraft Paper), we ensure each bag of plastic serves as an active barrier against moisture, oxygen, light, and mechanical stress.
Whitepaper overview on materials, environmental compliance, and global logistical security.
China's packaging supply chain remains the most robust globally, offering unmatched material availability, raw plastic monomer refining, and dynamic logistics. By sourcing specialized resins (linear low-density polyethylene, biaxially-oriented polypropylene, and high-barrier metalized films) from regional hubs, Chinese suppliers guarantee pricing stability and high customization agility that Western converters struggle to match.
For B2B procurement managers, sourcing standard and high-barrier plastic bags requires striking a balance between puncture resistance, heat-seal strength, and optical clarity. Global food, pharmaceutical, and electronic brands demand stringent quality control (QA) reports, consistent thickness tolerances (measured in microns), and compatibility with automated Form-Fill-Seal (FFS) packaging systems.
Exporting to over 30 countries requires complete compliance with target-market safety laws. This includes meeting FDA 21 CFR regulations for direct food contact in the United States, EU Regulation No 10/2011 on plastic packaging, REACH compliance, and ISO 9001:2015 standards. At Yuanzhong Pack, our material structures undergo regular testing for heavy metal migration and toxicity to guarantee user safety.
From custom coffee packaging film rolls to multi-layer pet food bags, we engineer our materials using multi-layer lamination processes. For instance, PET provides printability and mechanical strength; VMPET or Aluminum Foil offers a robust barrier against oxygen and UV light; and LLDPE serves as a reliable heat-seal layer to prevent micro-leaks and structural failures during transport.
The global packaging sector is undergoing a massive shift toward circularity. As an industry-forward Chinese supplier, we offer eco-friendly alternatives including recyclable mono-material PP and PE structures, bio-based Kraft paper laminated pouches, and PLA (polylactic acid) compostable options. These reduce carbon footprints while maintaining high-efficiency barrier ratings (WVTR and OTR).
Our packaging solutions find diverse applications across sectors worldwide. These include sterile packaging for medical disinfection pads, oxygen-barrier snack film rolls for food freshness, large-capacity leak-proof doy-packs for industrial liquids, and puncture-resistant pouches for frozen agricultural goods. We tailor each structure to its specific application environment.
Connecting with clients globally and expanding our trade footprint across 10+ countries.
Collaborating with over 20 global brands to deliver high-quality, high-barrier packaging solutions.
Technical answers to common questions about materials, regulatory compliance, and printing customization.
The Water Vapor Transmission Rate (WVTR) and Oxygen Transmission Rate (OTR) are primarily determined by the material composition and layer thickness. At Yuanzhong Printing, we laminating biaxially oriented films (like PET or BOPP) with high-barrier functional layers such as Aluminum Foil (AL), Metalized PET (VMPET), or EVOH. These composite structures are engineered to block light, moisture, and gaseous exchange, preserving product freshness and extending shelf life.
We source only virgin plastic resins (BOPP, PET, PE, CPP) from verified petrochemical manufacturers. All pigments, adhesives, and solvents utilized in our gravure printing lines are food-grade and comply with international standards. This includes compliance with US FDA 21 CFR 177.1520 and EU Directive 10/2011. Regular migration testing guarantees that chemical residues remain well below global detection limits.
The MOQ typically depends on the bag dimensions and design complexity, usually starting at 10,000 to 20,000 units for pre-formed bags, or 300-500 kg for custom roll stock. Lead times for new designs average 15-25 days, which includes structural plate design, multi-stage gravure printing, lamination, curing, slitting, and final quality control checks.
Gravure printing offers superior color consistency, registration accuracy, and image sharpness over long production runs. The engraved steel cylinders are highly durable, ensuring consistent output across millions of impressions. This makes gravure printing highly cost-effective for large-volume retail packaging compared to flexography, which is better suited for smaller runs.
Yes, we supply fully recyclable mono-material structures (such as PE/PE laminates) that can be integrated into standard recycling streams. We also offer bio-degradable PLA composites and high-barrier Kraft paper structures with plant-derived, compostable inner linings, helping brands meet their sustainability targets.
Direct supply from our certified facility, offering high seal integrity and custom surface finishing.
