Explore our engineered protective films, dynamic flexible laminates, and specialized sealing pouch configurations designed to preserve structural safety, shelf freshness, and brand presentation.
Established in 2001 in the Jiedong District of Jieyang City, Guangdong Province, Jieyang Yuanzhong Printing Co., Ltd. has grown to become a pioneer in the specialized plastic packaging converting and printing industry. With over two decades of technical evolution, we configure, laminate, and produce structural flexible films and heat-seal plastic pouches for food processing, FMCG, medical, and agricultural markets globally.
As an advanced, private-run manufacturing entity, we operate under a strict quality management system that allows us to ensure precision at every stage. Our infrastructure hosts advanced production capabilities, including Japanese Komori fully automatic printing lines, high-speed dry and solvent-free laminating stations, and intelligent inspection equipment. By managing our processes internally, we run a monthly output capacity exceeding 240 metric tons of composite material, securing both high capacity and consistent supply chain continuity for domestic and international contract buyers.
At Yuanzhong Pack, our competitive edge relies on targeted research and engineering customization. We recognize that standard solutions cannot address distinct barrier requirements, shipping constraints, or high-speed packaging equipment. Consequently, our engineering staff collaborates with client development teams to modify film chemistry, layer counts, seal dimensions, and surface properties. Our global distribution network regularly serves buyers across more than 30 countries in North America, Europe, Southeast Asia, and the Middle East, confirming our position as a reliable international supplier.
Sustainable materials are shifting the design parameters of flexible seal packaging. As a professional converter, Jieyang Yuanzhong is evolving from multi-material non-recyclable laminations toward recyclable and biodegradable mono-material polymer structures.
Traditional high-barrier bags utilize complex PET/AL/PE laminations that resist recycling. Our development path focuses on Mono-PE and Mono-PP structures that match the oxygen/moisture barrier standards of composite foils while meeting strict European and North American circular economy regulations.
We combine biodegradable Polylactic Acid (PLA) polymers with sustainably sourced natural Kraft paper to produce robust barrier packaging. These composite bags decompose naturally under commercial composting conditions, helping brands minimize environmental impact.
By refining the melt flow indexes of internal linear low-density polyethylenes (LLDPE), our sealing films maintain structural integrity across wide thermal processing windows. This avoids seam failures even when packing powder, lipids, or volatile chemical compounds.
| Material Configuration | WVTR (g/m²/24hr) | OTR (cc/m²/24hr/atm) | Recyclability Rating | Primary Industrial Use Case |
|---|---|---|---|---|
| PET / AL / LLDPE (Foil Laminate) | < 0.01 | < 0.01 | Non-Recyclable | Long shelf-life milk powders, dehydrated foods, military rations |
| BOPA / LLDPE (Nylon Laminate) | < 0.8 | < 25.0 | Hard to Recycle | Heavy liquid stand-up pouches, pet food, puncture-prone materials |
| MDO-PE / EVOH / PE (High-Barrier Mono) | < 0.15 | < 0.5 | Fully Recyclable (Code 4) | Sustainable snack food packaging, organic cereals, retail foods |
| Kraft Paper / PLA (Bio-based) | < 2.5 | < 85.0 | Industrial Composting | Eco-friendly specialty tea/coffee pouching, organic snack packaging |
Every market segment operates under unique technical challenges. We construct custom packaging configurations that optimize barrier performance, product protection, and filling line efficiency.
Our food-grade films comply with FDA regulations and EC Directives. Formulations with EVOH and metallized barriers block oxygen and water vapor transmission, preventing staling and rancidity in snack foods, potato chips, and dry goods.
Pet diets require robust packaging designed to resist fats, maintain oil barrier properties, and withstand puncturing. Our multi-layer co-extrusion technology produces flat-bottom and quad-seal bags that support heavy weight loads while preventing grease migration.
For packaging fine chemicals, seeds, and soil additives, sealing security is critical. Our heavy-duty industrial LDPE-blend materials resist punctures, environmental stress cracking, and acid/alkali exposures, ensuring transport safety.
Our manufacturing facility integrates modern automated systems to manage throughput, track quality parameters, and ensure timely production schedules. Through gravure printing technology, we combine high speed with precise graphic execution.
Gravure printing remains a preferred method for printing packaging materials at high volumes. Utilizing metal cylinders etched with microscopic ink cells, this system applies deep ink layers that produce high color saturation, clean fine lines, and stable color density across millions of linear meters. Combined with electronic register controls, it maintains visual quality at running speeds of up to 250 meters per minute.
Operating in international markets requires adhering to regional regulatory frameworks and logistics requirements. Jieyang Yuanzhong ensures that all products are backed by compliance documentation and reliable shipping services.
We maintain quality and raw material traceability systems that comply with global safety standards. Our food contact packaging films utilize FDA-approved resins, free from heavy metals, BPA, and phthalates. We secure SGS testing certificates and ISO 9001:2015 quality certifications, enabling smooth customs clearance at major international ports.
To support varied procurement processes, we work with multiple incoterms, including FOB Shenzhen, CIF Destination Ports, and DDP shipping direct to customer warehouses. We pack finished pouches in heavy double-wall corrugated cartons secured on heat-treated pallets to prevent humidity or damage during ocean transit.
