High-Barrier Materials, Premium Aromatics Preservation, and Customizable Solutions Built for Global Coffee Roasters and Distributors.
Explore our diverse range of custom printing films and high-barrier bag designs engineered for global markets.
Established in the Jiedong District of Jieyang City, Guangdong Province, Jieyang Yuanzhong Printing Co., Ltd. has developed over two decades of high-caliber expertise in packaging decoration printing and plastic barrier pouch fabrication. Operating as a premier private enterprise, we serve as a backbone manufacturer for global entities requiring high-barrier coffee plastic bags and custom roll stocks.
Our commitment to excellence is reflected in our advanced production facilities. We feature imported high-performance equipment including Japan Komori fully automatic printing production lines. Achieving an impressive monthly output exceeding 240 tons, we scale dynamically to handle high-volume bulk supply chains for clients across more than 30 countries globally.
By focusing on custom composite structures, precise rotogravure printing, and functional degassing valves, Yuanzhong Pack protects both roasted and ground coffee beans. We help roasters preserve delicate aromatics, prevent rancidity, and stand out on crowded retail shelves.
Understating material layer dynamics, gas transmission rates, and sustainable evolutions within coffee bag engineering.
Standard packaging lets moisture and oxygen seep in, degrading delicate coffee oils. Our composite structures combine PET, VMPET, BOPP, and food-grade PE. This design blocks oxygen, moisture, and UV rays, maintaining an Oxygen Transmission Rate (OTR) below 1.5 cc/m²/24hr. For premium selections, we integrate solid Aluminum Foil (AL) layers to achieve near-zero gas permeability.
Freshly roasted coffee releases significant volumes of Carbon Dioxide (CO2). Without a way to escape, this gas causes sealed bags to swell and burst. Our ODM integration of one-way degassing valves allows high-pressure CO2 to vent from the inside out. At the same time, it prevents external oxygen from entering, stopping oxidation and preserving the coffee's aromatic freshness.
Driven by global demands for plastic waste reduction, our research department is developing sustainable barriers. We design 100% recyclable mono-material structures (PE/PE) and compostable packaging films made from PLA (Polylactic Acid) and PBAT. These materials biodegrade into natural compounds without releasing toxic residues, meeting international environmental standards.
Historically, high-barrier laminations required composite materials (like PET/AL/PE) that are difficult to recycle. Our technical roadmap focuses on developing advanced High-Barrier Mono-Material laminates (such as MDO-PE/PE). By stretching PE film in the machine direction, we optimize tensile strength and heat resistance. This process enables it to replace traditional PET outer layers. When paired with high-barrier EVOH co-extrusions, these mono-materials match traditional plastic packaging's performance while remaining fully recyclable.
A look into how we manufacture high-barrier plastic packaging under strict quality control.
Rotogravure printing delivers thick ink layers, vibrant colors, and fast speeds for complex designs.
We laminate multiple film layers using solventless composite methods to ensure high barrier properties.
High-speed slitting machines cut laminated master rolls to precise width requirements.
Fully automated machines shape, insert valves, apply zippers, and heat-seal the coffee bags.
Every batch undergoes seal-integrity testing, is packed, and loaded for shipping.
Adapting packaging designs to suit commercial roasters, specialty cafes, and large retail distributors.
To preserve single-origin profiles, specialty roasters need packaging with excellent barrier properties. We offer customized stand-up pouches (Doypacks) and flat-bottom bags. These can be integrated with front zippers, tear notches, and premium matte finishes to reflect the artisanal quality of the coffee inside.
High-volume commercial brands require packaging that maximizes shelf space and performs well on automated filling lines. Our side-gusseted bags and quad-seal configurations offer structural stability, making them easy to stack and display on retail shelves.
Coffee suppliers serving hotels, restaurants, and cafes need larger packaging sizes. We manufacture heavy-duty, high-barrier bulk bags ranging from 1kg to 5kg. These are built with reinforced laminates to prevent punctures and tears during transport and storage.
How Yuanzhong Printing integrates automation and smart processes to maintain reliable capacity.
Located in the Jiedong District of Jieyang City, our facility utilizes automated manufacturing workflows. By using computerized tension control and inline defect detection systems, we ensure consistent quality across production runs.
Our integrated system connects our printing, laminating, slitting, and bag-making departments. This setup minimizes material waste and helps us maintain a reliable production capacity of 240 tons per month, shielding our international customers from supply chain disruptions.

Connecting with clients across more than 10 countries to showcase our printing and packaging innovations.
Partnering with over 20 global brands to deliver high-quality printing and packaging solutions.
Meeting food safety guidelines and regulatory requirements across international jurisdictions.
Our materials comply with FDA direct food contact regulations. The inner linear low-density polyethylene (LLDPE) film is free from contaminants, maintaining food safety standards during hot-fill or high-pressure packaging operations.
We test our barrier films under EU Regulation No 10/2011 guidelines. Through regular migration tests, we confirm our packaging materials are safe and suitable for shipping food products within European markets.
We provide required customs paperwork including certificates of analysis, clean bills of lading, and certificates of origin. Our team coordinates logistics to ensure import clearance runs smoothly at destination ports worldwide.
Answers to common technical, material, and logistics questions from procurement and packaging teams.
Freshly roasted coffee beans naturally release Carbon Dioxide (CO2). If sealed in an airtight bag without venting, this gas causes the package to expand and potentially rupture. The one-way valve allows internal CO2 to escape while blocking external oxygen from entering, preventing oxidation and preserving fresh aroma and flavor profiles.
For custom rotogravure printing projects, MOQs typically range from 10,000 to 20,000 bags per size/design, depending on the bag's dimensions and material structure. This MOQ ensures setup costs for plates and machinery run efficiently. For unprinted stock pouches with custom label options, we can accommodate smaller batch sizes.
Yes, we manufacture recyclable mono-material structures (PE/EVOH-PE) that can be integrated into standard recycling streams. We also produce compostable laminates using plant-derived PLA (Polylactic Acid) and bio-based barrier films. These eco-friendly materials degrade into natural components under compost conditions without leaving behind toxic microplastics.
Gravure printing uses metal cylinders with etched designs to transfer ink directly onto the film, delivering excellent color richness, detail, and image durability. This method is well-suited for high-volume orders. Flexographic printing uses flexible photopolymer plates, which can have lower setup costs for shorter runs but may not match gravure's level of fine detail and deep ink saturation.
