Explore our top-tier flexible barrier laminated roll stock and pre-made pouch options engineered for maximum freshness, high-barrier preservation, and retail shelf appeal.
Established in 2001 and located in Jiedong District, Jieyang City, Guangdong Province, Jieyang Yuanzhong Printing Co., Ltd. stands as a premier B2B manufacturer in the global flexible packaging printing industry. Under our flagship trade brand Yuanzhong Pack, we have committed over two decades to perfecting packaging decoration printing, barrier film laminations, and the production of state-of-the-art flat bottom bags, stand-up pouches, and custom roll stock options.
Our packaging facilities boast a range of highly advanced, imported machinery, including the state-of-the-art Japan Komori fully automatic printing production lines. Operating dynamically at scale, our factory maintains a reliable monthly output exceeding 240 tons of finished packaging solutions. This manufacturing throughput guarantees stable supply chains, short lead times, and seamless custom product delivery to global buyers across 30+ countries.
Why international brands are transitioning from traditional box packaging and standard stand-up pouches to high-performance flat bottom designs.
Flat bottom pouches provide five printable surfaces: front, back, bottom, and two side gussets. This structure maximizes shelf presence and allows manufacturers to print rich nutritional information, dynamic graphics, and localized instructions without cluttering the brand aesthetics.
Unlike rigid boxes or glass jars, the flat bottom pouch lays completely flat during empty shipping, drastically lowering incoming freight costs and warehousing space. Once filled, the pouch stands sturdy, maximizing pallet packing density by up to 30% compared to traditional configurations.
Modern consumers demand sustainable packaging materials. Top-tier factories now offer flat bottom pouches manufactured using mono-material structures (such as fully recyclable PE/PE or PP/PP laminations) and compostable paper coatings, helping global enterprises meet ESG regulatory goals.
A true high-quality flat bottom pouch must do more than look good; it must serve as an active protective shield. At Yuanzhong Pack, our material science specialists design customized multilayer composite barrier structures tailored to individual product attributes:
By controlling Oxygen Transmission Rates (OTR) and Water Vapor Transmission Rates (WVTR), we extend food preservation timelines by up to 24 months, drastically minimizing product returns for brands globally.
How modern manufacturing automation, raw material integration, and logistical agility position Jieyang Yuanzhong as an industry-leading packaging plant.
Our integration of Japan Komori automatic lines and smart slitting/bagging lines minimizes manual error, ensuring register precision up to 0.1mm. High speed, continuous automated monitoring translates to stable quality across massive production volumes.
We source raw plastic films, inks, and adhesives only from FDA-approved, SGS-certified international suppliers. Advanced gas chromatographs, tensile strength testers, and seal pressure tests ensure 100% compliance with strict international food-contact safety standards.
Based in Jieyang, Guangdong, we sit at the heart of South China's polymer and logistics hub. With proximity to major deep-water ports (Shenzhen and Guangzhou), we offer accelerated container loading, efficient customs clearance, and optimized ocean freight rates.
Our factory utilizes high-durability gravure printing and composite laminations to produce packaging products with thick ink layers, high saturation, and optimal sealing strength.
Yuanzhong Pack actively participates in global packaging exhibitions across more than 10 countries, keeping us connected with global sourcing standards and new material technologies.
We work with over 20 global brands, demonstrating our commitment to quality, product development, and supply consistency.
















Our high-quality flat bottom pouches and custom films provide targeted barrier protection for diverse retail and food-service environments.
Integrated with unidirectional degassing valves, our flat bottom coffee pouches allow roasted beans to vent carbon dioxide while preventing oxygen from entering. This preserves coffee freshness and delicate aromatic profiles.
Designed with thick, puncture-resistant polymer structures, our pet food stand-up bags hold up to 10kg without bottom failure, keeping contents dry and preserving flavor profile integrity.
High-barrier metallized films protect potato chips, chocolate, and puffed snacks from oxygen and water vapor transmission, ensuring consistent crunch and freshness.
For flour, cake mix, and sugar packaging, flat bottom designs offer box-like stability on retail shelves, reducing spillage and maximizing retail shelf efficiency.
