Establishing Global Benchmarks in Packaging & Decorative Gravure Printing Since 2001
Jieyang Yuanzhong Printing Co., Ltd. is a preeminent leader in the flexible packaging and decorative printing industry. Formally established in 2001 in the Jiedong District of Jieyang City, Guangdong Province, China, our organization has dedicated over two decades to developing cutting-edge manufacturing processes, strict quality control methodologies, and high-performance material science.
Our expansive industrial facilities are outfitted with elite manufacturing infrastructure, highlighted by imported Japanese Komori fully automatic high-speed printing production lines. This allows us to command a robust monthly production throughput exceeding 240 metric tons, satisfying the massive supply requirements of our global business network spanning over 30 countries.
We specialized in structural polymer films, barrier foil lamination, and bespoke bag-making configurations. By integrating expert material engineering with raw materials verified by international compliance agencies, Yuanzhong Pack remains a trusted supplier for businesses seeking dependable food-grade product safety and brand presentation.
Roasted coffee is a highly complex organic substance sensitive to environmental factors. Our customized flexible plastic bag solutions address degradation hazards.
Upon roasting, lipids present within coffee beans easily oxidize when exposed to oxygen, resulting in stale taste and loss of aroma. Our customized plastic coffee packaging integrates high-efficiency Ethylene Vinyl Alcohol (EVOH) or aluminum metalized barrier films (VMPET) achieving Oxygen Transmission Rates (OTR) of less than 0.1 cc/m²/24hr.
Freshly roasted coffee releases significant volumes of Carbon Dioxide (CO2). Without gas venting, standard plastic packaging swells and ruptures. We configure one-way degassing valves that permit built-up carbon dioxide to escape the pouch structure while completely preventing atmospheric oxygen from filtering inward.
Hydrophobic inner-contact layers utilizing cast polypropylene (CPP) or linear low-density polyethylene (LLDPE) block ambient moisture. This ensures the dry coffee powder or whole roasted beans do not absorb humidity, preventing early chemical breakdown and mold risk inside the pack.
Comparative analysis of physical laminations used in modern plastic coffee bag manufacturing.
| Material Formulation | Barrier Efficiency | Aesthetic Characteristic | Target Coffee Subtype | Best Sustainability Value |
|---|---|---|---|---|
| PET / VMPET / LLDPE | High Barrier | Glossy/Metallic finish | Ground coffee powder, Instant mixes | Recyclable options emerging |
| MOPP / AL Foil / LLDPE | Ultra-High Barrier | Soft Matte finish | Premium specialty roasted coffee beans | Traditional standard barrier |
| Kraft Paper / VMPET / LLDPE | High Barrier | Organic tactile texture | Organic coffee, artisanal small-batch | Biodegradable outer layer |
| PET / EVOH-PE | Medium-High | High Transparency | Decaf beans, short-run retail packs | Monomaterial recycle friendly |
Our industrial process delivers thick ink laydowns, rich saturation, and consistent mechanical sealing properties across million-unit production runs.
In our factory line, gravure printing plays an essential role. By etching the desired layout designs onto high-durability cylinders, ink is directly transferred to the substrate film under controlled mechanical pressure. This technique excels over flexography or digital printing when handling high-volume contracts due to the exceptionally thick ink layers and accurate registration calibration. Whether you are running a metallic-flake logo design or a matte-finish coffee bag, gravure printing ensures consistency across long runs with minimal color variance.
How global food businesses leverage our manufacturing infrastructure for regional distribution compliance.
Coffee packaging requires certified food contact security. Our manufacturing lines use strict raw materials verified under international FDA regulations and EU food contact standards. This ensures that no hazardous micro-particles or plasticizers migrate into the coffee grounds during transportation or prolonged warehouse storage.
Operating a global coffee brand requires reliable lead times. Our plant’s 240-ton monthly capacity, backed by modern material warehouses in Guangdong, safeguards our clients against unexpected shortages. We maintain standard backup reserves of polymer resins and metallized films to prevent delays during peak packaging seasons.
By shipping our flexible plastic film rolls and pre-made stand-up pouches in compressed, lightweight flat packs, we reduce shipping volume compared to rigid containers. This layout minimizes ocean shipping costs and reduces carbon output per shipped unit.
Yuanzhong Pack is investing in next-generation material science to align with global environmental mandates.
Transitioning complex multi-layer laminates (e.g. PET/AL/PE) to monomaterial structures like PE/EVOH-PE. This structure maintains the required oxygen barrier properties while qualifying for standard recycling systems.
R&D efforts focused on Polylactic Acid (PLA) and polybutylene succinate (PBS) formulations. Our objective is to produce high-barrier compostable coffee pouches that naturally degrade in industrial composting facilities.
Integrating passive RFID tags and heat-sensitive color indicators on our roll films to allow automated inventory tracking and freshness checks at every point in the supply chain.
