Explore our high-performance functional films and custom bag selections engineered for ultimate freshness and durability.
Jieyang Yuanzhong Printing Co., Ltd. stands as a premier leader in the flexible packaging and printing sector. Headquartered in the strategically crucial Jiedong District of Jieyang City, Guangdong Province, our private enterprise has developed over 20 years of robust expertise, optimizing functional film coatings and structural design. We cater to complex, high-speed automated packaging lines, producing tailored food-grade solutions with physical barrier integrity.
Specializing in decorative gravure printing and composite structural pouch processing, we deploy fully integrated Japanese Komori automatic production lines alongside solvent-less laminators and intelligent slitting systems. Our facility achieves a monthly output exceeding 240 metric tons. This extensive scaling allows us to support dynamic supply chains across 30 countries, ensuring optimized lead times, strict safety standard adherence, and high tensile structural resilience.
Pioneering functional barrier sciences and circular design systems to align with global environmental mandates.
Transitioning from complex multi-polymer structures to recyclable PE/PE or PP/PP mono-material laminates. By using machine-direction orientation (MDO) technology, we achieve exceptional optical clarity, thermal stability, and mechanical strength while complying with the European Union's packaging circular economy regulations.
Integrating chemical oxygen scavengers, ethylene absorbers, and customized EVOH (Ethylene Vinyl Alcohol) co-extrusions into the polymer matrix. These active layers limit oxygen transmission rates (OTR) to less than 0.1 cc/m²/day, maintaining product freshness without synthetic additives.
Developing structural integrations for printed electronics, QR verification pathways, and embedded RFID/NFC tracking tags. These systems enable instant localized supply chain verification, anti-counterfeit confirmation, and interactive digital consumer engagement on retail shelves.
Operating under strict cleanroom conditions, our production integrates advanced mechanical execution with continuous quality monitoring.
Our manufacturing sequence uses state-of-the-art rotogravure printing to deliver high-resolution graphic rendering at run speeds of up to 300 meters per minute. Following printing, we utilize solvent-less dry lamination to fuse custom composite layers like PET, AL, VMPET, and PE, preventing chemical migrations. This process is followed by precision slitting, heat-seal bag formation, and robotic packaging to ensure every order arrives clean and fully optimized for automated filling lines.
Our facility in Guangdong utilizes localized upstream chemical resources and high-performance polymer suppliers. This integration secures our raw material supply, sheltering global partners from unexpected resin cost spikes or delivery delays. By maintaining local safety stocks of key films (such as BOPA, PET, and food-grade PE), we keep lead times reliable, even during seasonal shifts in global logistics.
Operating under Factory 4.0 guidelines, we use automated material transport, real-time heat-seal monitoring, and integrated quality control across every run. This setup reduces human error, cuts down waste, and improves energy efficiency. For our global partners, this means a reliable supply of packaging that meets strict international standards at a competitive cost.
A reference guide to matching laminate barriers and packaging designs to specific product needs.
Uses multi-layer laminates like PET/AL/PE or PET/VMPET/PE to prevent grease migration and block moisture. Integrated resealable zippers maintain freshness over multiple openings, while flat-bottom structures keep bags stable on retail shelves.
Requires high-strength composite structures, such as Nylon (BOPA) paired with LLDPE. This combination handles drop stress without puncture failures. Corner-spout designs support clean pouring, and customized fitments work smoothly with automated liquid filling lines.
Uses high-barrier metallized films or aluminum foil layers to keep oxygen and moisture out. Degassing valves allow carbon dioxide to escape from fresh coffee without letting outside air back in, protecting aromatic oils from oxidation.
We prioritize regulatory compliance across every production run. Our raw resins, process adhesives, and printing inks meet strict food-contact safety standards worldwide. We run regular migration and trace metal testing to ensure our packaging is safe for US, EU, and international distribution.
Working closely with third-party testing labs, we provide complete compliance documentation, including FDA certificates and raw material traceability reports. Our quality management system covers every step of production, ensuring that all shipments arrive at your warehouse ready for use and fully documented.

Cooperating with More Than 20 Brands: A Testament to Our Commitment to Excellence
Expert insights on materials, lead times, and customization choices for global procurement teams.
MoQs vary based on the specific bag dimensions and custom film structures required. Generally, for printed stand-up bags, our MoQ ranges between 10,000 and 20,000 pieces. For custom rollstock films, the MoQ starts at 500 kilograms per structure. These minimums ensure setup efficiency and reduce raw material waste on our high-speed Japanese Komori printing lines.
We use specialized solvent-less laminating machines equipped with inline tension control and automated adhesive dosing. Our team monitors the adhesive mix ratio continuously to ensure a secure bond. After lamination, rollstock goes into temperature-controlled curing rooms to cross-link the adhesive properly, preventing delamination and chemical migration.
Yes, we offer fully recyclable mono-material structures (such as PP/PP or PE/PE) that match the barrier performance of traditional multi-polymer laminates. By using oriented films (MDO-PE) and EVOH barrier layers, we protect products from oxygen and moisture while meeting European recycling guidelines.
We test every batch for key barrier metrics. Our QA team measures Oxygen Transmission Rate (OTR) and Moisture Vapor Transmission Rate (MVTR) using specialized laboratory equipment. We also run tensile strength, coefficient of friction (COF), and heat-seal strength tests to make sure the film performs reliably on automated packaging lines.
We prevent seal leakage by pairing BOPA (nylon) with customized inner LLDPE layers to handle mechanical impact. During bagging, we use dual-stage heat sealing and cold-press cooling to secure the spout fitment. Finished pouches undergo pressure decay and burst tests to verify seal strength before shipping.
First-time custom orders take approximately 18 to 25 days. This includes physical cylinder preparation and engraving (typically 5-7 days), printing, lamination, curing, converting, and final quality control. Repeat orders bypass the cylinder fabrication phase and can usually be shipped within 12 to 15 days.
Yes, we use the Pantone Matching System (PMS) and spectrophotometers to track color consistency. During printing, inline cameras compare ink density and shades with approved digital proofs, keeping color deviations (Delta E) within strict tolerances across large production runs.
