The contract packaging (Co-Packaging) and custom flexible packaging sector is undergoing a profound paradigm shift driven by rapid automation, stringent global safety compliances, and the demand for longer product shelf lives. As FMCG brands strive to shrink time-to-market cycles, the global manufacturing center has increasingly centralized around highly integrated partners in China. Modern packaging facilities no longer merely function as raw material converters; they act as primary engineering allies offering tailored chemical compositions, multi-layered high-barrier sheets, and precise surface properties to survive complex supply chains.
In industrial packaging operations, variables like OTR (Oxygen Transmission Rate) and WVTR (Water Vapor Transmission Rate) dictate the viability of food, pharmaceutical, and chemical products. Top-tier Chinese manufacturers utilize advanced barrier layers containing EVOH (Ethylene Vinyl Alcohol), PVDC, and pure aluminum foil layers to match the exact requirements of dry food systems, milk powders, and highly volatile pharmaceutical goods. Furthermore, co-packing processes must align with high-speed automated packaging machinery (VFFS/HFFS lines), requiring exceptional mechanical tensile strength, controlled coefficients of friction (COF), and heat-seal windows that guarantee structural integrity under extreme processing conditions.
Established in 2001 in Jiedong District, Jieyang City, Guangdong Province, Jieyang Yuanzhong Printing Co., Ltd. has grown to become a premium supplier in the flexible packaging and printing industries. For over two decades, our team has integrated custom material development with high-fidelity printing to support regional and international brands. Our manufacturing complex features imported, state-of-the-art production machinery, including Japan Komori fully automatic printing lines, enabling us to sustain an production capacity exceeding 240 tons monthly.
Our operations cover the entire lifecycle of custom flexible packaging—from raw resin compounding to custom lamination, slitting, and bag forming. As a specialized OEM and ODM vendor, we configure packaging dimensions, multi-layered structures, tear notches, zippers, and spout properties to solve the exact demands of international brands. By exporting to over 30 countries, we maintain high standards of quality management, ensuring compliance with global regulatory criteria.
Gravure printing represents the gold standard for long-run flexible packaging, offering deep ink transfer, high color fidelity, and superior mechanical durability. Explore our five-stage manufacturing process below.
High-speed Japanese Komori printing cylinders transfer vibrant inks onto substrates, maintaining tight registry control across thousands of meters.
Dry and solvent-free lamination techniques fuse diverse films (PET, AL, PE, Kraft) into a highly cohesive barrier laminate.
Ultra-sharp slitting systems shear wide laminates into custom web widths designed for downstream packaging machinery.
Advanced pouch-makers convert rolls into stand-up pouches, spout pouches, or zipper bags with reliable heat-sealed margins.
Finished items undergo strict visual inspection, pressure testing, and secure crating for damage-free shipping.
We tailor specific chemical compositions and structural designs to meet the distinct challenges of different product segments.
Pet kibble requires reliable protection against moisture gain and oil migration. We supply high-puncture-resistant laminate systems utilizing PET/AL/PE or BOPA/PE. This ensures fat molecules stay encapsulated, preventing oxidation and off-odors. Incorporating heavy-duty zipper closures ensures the food remains fresh after opening.
Both coffee beans and ground blends are highly sensitive to oxygen and UV degradation. Our custom high-barrier aluminum foil rolls block gas transmission entirely. When equipped with one-way degassing valves, they safely vent carbon dioxide gas from freshly roasted coffee without admitting external air, preserving essential aroma compounds.
For dynamic liquid containment, physical stability is critical. Our spout pouches are manufactured using robust nylon (BOPA) and custom-modified heat-sealing layers. These pouch configurations survive drop testing, resist stress cracking, and feature heat-welded plastic spouts that eliminate leakage risks during transport and dispensing.
Global regulatory shifts are urging brands to replace multi-layer mixed plastic packages with recyclable alternatives. Yuanzhong is at the forefront of this shift, offering FDA-compliant monomaterial structures and eco-friendly Kraft paper laminates. Traditional structures merge polymers that cannot be separated in standard sorting systems; our new mono-PE laminates consolidate film properties into a single recyclable stream without losing barrier capabilities.
Additionally, our degradable paper kraft pouches combine natural, renewably sourced paper sheets with thin inner barrier films to limit environmental impact. These configurations reduce dependency on fossil fuel plastics while meeting strict safety parameters for snack food, pet treats, and dry ingredients. By prioritizing these materials, we help clients adapt to EU circular economy directives and packaging waste limits.
