Our flagship OEM solutions combine structural integrity, advanced oxygen barrier coatings, and flawless aesthetic presentation to elevate your brand value.
Established in 2001 in the Jiedong District of Jieyang City, Guangdong Province, Jieyang Yuanzhong Printing Co., Ltd. has established itself as an authoritative leader in the plastic packaging and printing industry. Backed by over two decades of high-caliber experience, we combine premium raw materials with precision engineering to serve the diverse requirements of modern brands.
Yuanzhong Pack specializes in high-fidelity packaging decoration printing, alongside the custom manufacturing and multi-layer processing of high-performance plastic packaging bags. To maintain our reputation for unparalleled excellence, we have invested heavily in importing state-of-the-art machinery, including fully automatic printing production lines from Japan Komori. This superior manufacturing infrastructure enables us to achieve a massive monthly throughput of more than 240 tons, ensuring even high-volume orders are fulfilled on schedule.
Our capabilities span a vast array of customizations, from tailored barrier structures and unique dimensions to custom composite polymer matrices. Operating with a robust, streamlined logistics network, we proudly export to over 30 countries globally, reinforcing our role as a trusted supply partner for international operations.
Developing flexible packaging is an exercise in molecular engineering. Protecting contents from external degradation requires calculated structural design.
We analyze seal integrity using ASTM F2029 heat seal curve profiling and ASTM F88 peel testing. This ensures seal lines prevent molecular ingress, maintaining critical gas levels inside the bag to protect content freshness.
By pairing high-barrier films like metallized polyester (VMPET), nylon (PA), and aluminum foil (AL) with linear low-density polyethylene (LLDPE) seal layers, we yield ultra-low Oxygen (OTR) and Water Vapor Transmission Rates (WVTR).
Our raw polymer material selection ensures a broad sealing temperature window. This prevents burn-through or weak seals during automated vertical or horizontal form-fill-seal (VFFS/HFFS) packaging operations.
"A robust seal is more than a closure; it is a vital shield that secures shelf life, preserves taste profiles, and protects food formulations against oxygen contamination, moisture loss, and physical transit stresses."
China's flexible packaging industrial clusters offer unparalleled advantages in technology integration, scaling capabilities, and cost efficiency.
Based in Jieyang, Guangdong, we operate within the epicenter of global polymer science and manufacturing. From direct access to premium plastic resins to custom mold making, plate tooling, and machinery fabrication, our localized supply chain reduces logistical lead times and material transport costs.
By leveraging Japanese Komori printing equipment alongside advanced high-speed gravure presses, we achieve unmatched registration accuracy. This enables vibrant, multi-color packaging printing with sharp fine lines and consistent gradient rendering, all at high output velocities.
Our plant handles short prototype test runs as easily as large mass-production cycles. Our high-throughput facility adapts to shifting demand, ensuring continuous product flow for dynamic markets.
Gravure printing occupies a critical role in packaging due to its thick ink layer, high color saturation, plate durability, stable print quality, and rapid line speed.
We design packaging around the specific physical and chemical requirements of diverse consumer and industrial products.
For puffed snacks, biscuits, and baking mixes, maintaining internal nitrogen flush levels is critical. Our aluminum foil laminated materials feature gas barriers that protect contents from light oxidation, preserving original texture and taste profiles. Custom shaped pouches also improve shelf presence.
Protein powders and infant formulas require robust protection against moisture ingress, which can cause clumping and spoilage. Our multi-layer co-extrusion films provide dependable moisture protection, ensuring dry formulations remain stable throughout their shelf life.
Freshly roasted coffee continuously releases carbon dioxide. Our coffee film rolls are engineered for compatibility with degassing valves, letting gases escape while blocking oxygen from entering. This maintains the coffee's aromatic compounds.
Our heavy-duty pet food bags and liquid spout pouches are designed to resist puncture and drop impacts. Tested to support heavy loads and high-viscosity liquids, they are ideal for high-volume pet food and liquid products.
The flexible packaging industry is moving toward high-efficiency materials that lower carbon footprints while maintaining product shelf life. Companies worldwide are adjusting their procurement strategies to balance sustainability goals with cost requirements.
Standard multi-layer films combining different plastics can be difficult to recycle. Modern developments focus on Mono-Material PE or PP laminates, which offer comparable barrier properties while simplifying the recycling process. We are actively refining these structures to meet green regulatory requirements in Europe and North America.
Smart packaging incorporates QR codes, anti-counterfeiting marks, and temperature-sensitive inks directly into the design. Brand owners leverage these tools to share traceability data, connect with consumers digitally, and verify product authenticity.
As packaging speeds increase globally, roll films must perform reliably on automated packaging lines. This requires materials with low coefficients of friction (COF) and low-temperature sealing properties to prevent assembly-line bottlenecks.
