Engineered high-barrier films and customized pouch structures designed for ultimate food preservation and premium branding.
A micro-to-macro assessment of barrier performance, compliance dynamics, and technical roadmaps.
Global food exports rely on stringent regional alignments. From United States FDA CFR 21 criteria to European Union (EU) No 10/2011 regulations, every polymeric layer must exhibit zero toxicity, minimal migration thresholds, and clean solvent recovery levels. Food grade compliance ensures that polymer degradation does not compromise organoleptic properties.
Modern shelf stability relies on laminates combining PET, BOPP, AL, VMPET, Nylon, and cast polypropylene (CPP). Polyethylene (PE) layers supply secure low-temperature heat sealing, whereas Nylon adds puncture resistance. By tailoring the material recipe, we adjust protective barrier parameters precisely for snack foods, pet foods, and high-grease materials.
Gravure printing delivers unmatched color replication, precise ink layout control, and mechanical consistency for high-volume orders. Utilizing deep cells on copper cylinders, this technique applies thick, highly saturated ink layers, bringing complex custom brand designs and nutritional labels to life with exceptional graphic clarity.
Over two decades of precision manufacturing, technological leadership, and packaging excellence.
Established in 2001 in Jiedong District, Jieyang City, Guangdong Province, Jieyang Yuanzhong Printing Co., Ltd. (familiarly known as Yuanzhong Pack) is a premier private enterprise built on technical expertise and custom innovation. With over 20 years of focus, we specialize in high-end packaging decoration printing and high-performance plastic packaging bag manufacturing.
Our facilities house high-precision machinery, notably including fully automatic gravure printing production lines (such as the renowned Japan Komori automatic sheets/roll system capabilities). These capital investments empower our factory to reach a monthly output of over 240 tons of finished film roll stock and customized bags. This deep supply scale ensures consistent delivery timelines for major domestic operations and global distributors across more than 30 countries.
What defines Yuanzhong Pack is our scientific approach to customization. We recognize that moisture preservation, grease-resistance, gas isolation, and physical styling differ radically from chips to roasted turkey or coffee beans. Our product engineers assist customers from material profiling to the finalized packaging.
The scientific steps behind our superior food packaging production.
Our production floor leverages gravure printing and advanced composite lamination. Gravure technology stands out due to its high durability, consistent print distribution, fast run rates, and vibrant ink density. Explore the detailed steps below:
Applying food-grade inks to the outer substrate layer via high-speed cylinders.
Laminating the printed outer film with barrier layers using solvent-free adhesives.
Slicing wide web laminates into precise roll sizes matching the target dimensions.
Converting structured films into individual pouches with zippers, spouts, or custom shapes.
Sealing final batches into heavy-duty corrugated cartons to protect them during transport.
How our customized ODM formulations protect diverse product categories.
Snacks require high nitrogen flushing and moisture-proof metallized layers (such as VMPET or pure AL foil) to prevent lipid oxidation and preserve crunch. Our custom printed snack packaging film handles high sealing speeds on packaging lines without thermal distortion.
Roasted coffee off-gasses carbon dioxide while being highly sensitive to oxygen and ambient moisture. We build trilaminate systems with integrated degassing valves to allow gas venting without letting external oxygen enter the bag.
Pet foods feature high oil content and require robust puncture resistance to survive handling. Our flat-bottom zipper pouches utilize dense co-polymer materials to block grease migration and maintain freshness.
Pioneering sustainable and circular economy frameworks in flexible food packaging.
Traditional multi-material films are difficult to recycle because they combine different polymer families. The industry is moving toward mono-material options, such as all-polyethylene (PE) laminates. By matching the mechanical and barrier properties of combined PET/PE films, we provide options that can be processed directly in standard recycling streams.
Ethylene Vinyl Alcohol (EVOH) co-polymer layers are replacing thick aluminum foils in many modern packaging designs. EVOH offers excellent oxygen barrier performance in a ultra-thin, transparent profile, allowing consumers to view the product while protecting it from gas exchange.
Our research and development pipeline actively tests bio-derived resins like PLA (Polylactic Acid) and PBS (Polybutylene Succinate). When blended with paper substrates, these materials degrade naturally under industrial composting conditions without leaving microplastic residues.
A testament to our long-term commitment to quality and service across the food sector.
