Explore our elite portfolio of FDA-approved, laminated rolls and multi-layered functional pouches designed for state-of-the-art packaging lines.
Jieyang Yuanzhong Printing Co., Ltd. stands as a benchmark of engineering precision in the global packaging printing industry. Established in 2001 and strategically located in the Jiedong District of Jieyang City, Guangdong Province, China, our private enterprise has logged more than two decades of industrial printing excellence. Over these 20+ years, we have committed ourselves to rigorous material testing, advanced processing technologies, and localized client support services to meet the strict demands of international supply chains.
At Yuanzhong Pack, our specialties encompass high-precision packaging decoration printing alongside the comprehensive production and processing of customized flexible packaging bags, including high-barrier liquid spout bags, pet food barrier pouches, and roll stock films. We leverage imported technology, notably our Japan Komori fully automatic printing production lines, allowing us to maintain a staggering monthly output capacity exceeding 240 tons. This ensures reliable supply chains for major global brands in food, personal care, and industrial liquids.
With an extensive global export network, we proudly service dynamic markets in more than 30 countries across Europe, North America, Southeast Asia, and the Middle East. Through strict adherence to E-E-A-T principles and quality-first guidelines, we tailor packaging solutions that respect local regulatory compliance protocols and unique market demands.
Gravure printing forms the backbone of modern flexible packaging. The high-durability plates and automated lines at Yuanzhong Pack deliver ink saturation and mechanical integrity that set industry standards.
In the gravure printing process, ink layers are transferred directly from engraved metal cylinders onto film webs. This technique is globally acclaimed for its ability to lay down a thick ink layer, yielding highly saturated colors and unmatched registration precision. Our composite process laminates multiple film layers (such as PET, AL, NY, and PE) using solvent-free adhesives to achieve high barrier performance, protecting inner contents against moisture, oxygen, and UV light degradation. Automated slitting and high-speed bag-making lines finalize the bags with robust seals, guaranteeing leak-free performance even under heavy physical stress.
Flexible packaging with integrated spouts is replacing traditional rigid plastic bottles, glass jars, and metal cans. Here is how modern brands leverage this format.
Designed for baby purees, juices, energy gels, and functional health drinks. The lightweight construction slashes outbound transport costs and reduces volumetric shipping footprints by up to 85% compared to empty glass or rigid PET containers.
Customized high-chemical-barrier films (including NY and specialty OPA layers) withstand detergents, automotive fluids, agrochemicals, and liquid fertilizers without leaking, chemical leaching, or stress cracking at the spout joint.
Ideal for refills of hand soaps, hair shampoos, lotions, and facial masks. Designed with fine, anti-drip dispensers to enhance the end-user experience, while reducing plastic waste output by up to 70% in line with global sustainability goals.
The industrial adoption of spout bags has grown due to their efficiency. They minimize product waste by allowing consumers to squeeze out up to 99% of the contents. Additionally, their flat shipping profile significantly reduces warehousing and transit emissions, providing a tangible carbon reduction benefit that aligns with ESG targets in key consumer markets.
Our structural material selections are tailored to specific product densities, barrier requirements, and shipping environments.
| Bag Classification | Standard Structural Material Spec | Ideal Applications | Primary Advantages |
|---|---|---|---|
| High-Barrier Foil Pouches | PET / AL / NY / LLDPE (4-Layer Laminate) | Liquid Juices, Organic Purees, Nutritional Gels | Near-zero O2 and H2O transmission rates, extended shelf-life up to 24 months. |
| Clear High-Barrier Pouches | PET / Nylon (OPA) / R-PE or LLDPE | Clear Beverages, Dish Soaps, Pet Purees | High puncture resistance, visual clarity for contents, drop test certified. |
| Eco-Friendly / Kraft Paper Pouches | Kraft / Paper / Bio-Based Barrier / PLA or PE | Dry Powders, Organic Tea, Dry Pet Treats | Premium textured feel, compostable options, biodegradable natural aesthetic. |
| Heavy-Duty Industrial | PET / NY / High-Strength PE (Thick Gauge) | Automotive Oils, Concentrated Chemicals | Anti-burst seam architecture, high resistance to acid-alkali chemical attacks. |
At Jieyang Yuanzhong Printing, we run our production lines in strict compliance with globally recognized certifications, including FDA standards for direct food-contact surfaces. Our raw polymer resins, barrier adhesives, and printing inks undergo strict migration testing to ensure zero heavy metal, BPA, or phthalate contamination. This makes our spout bags safe for baby foods, nutritional supplements, and premium cosmetics.
Our laboratory performs continuous testing on all batches:
• Drop Tests: 1.5-meter vertical free-fall verification.
• Burst Strength: High-pressure pneumatic seal integrity tests.
• Fitment Torque Tests: Ensures child-resistant caps are easy to open for seniors while maintaining a tight seal during transport.
How Yuanzhong Pack is investing in next-generation materials to support circular economies and reduce plastic tax liabilities.
Transitioning from traditional multi-layer structures (e.g. PET/AL/PE) to mono-material laminations (e.g., all-PE structures). This allows the entire spout bag, including the spout fitment, to be recycled in PE streams without layer separation.
Integrating food-safe PCR resins into outer film structures. This lowers virgin polymer reliance and assists multinational consumer brands in hitting global recycled content targets.
Partnering with agricultural polymer producers to offer high-barrier plant-derived film layers. These decompose in composting facilities, returning organic materials back to the soil.
Connecting with global customers through trade shows in more than 10 countries and partnering with trusted global brands.
