Explore our foundational range of high-barrier, food-grade laminates optimized for automatic packing lines and custom pouch conversion.
Decades of Engineering Precision in Advanced Packaging Conversion
In the high-stakes sector of global logistics, preservation, and shelf-appeal, flexible packaging has transitioned from a fundamental containment commodity to a highly engineered product protector. As a premier OEM Flexible Packaging Co Manufacturer & Supplier, Jieyang Yuanzhong Printing Co., Ltd. has stood at the interface of advanced material science and high-speed packaging conversion since 2001. Over two decades of operational experience have allowed our engineers to perfect structural barrier configurations, assuring compatibility with high-speed automated vertical form-fill-seal (VFFS) and horizontal form-fill-seal (HFFS) packaging machines.
Operating a private manufacturing hub based in Jiedong District, Jieyang City, Guangdong Province, China, Yuanzhong Pack maintains a state-of-the-art facility featuring Japan Komori fully automatic printing production lines alongside advanced high-speed rotogravure machinery. Achieving a steady monthly throughput exceeding 240 metric tons, we combine extensive raw material capacities with strict QA/QC testing protocols. This structure ensures every production lot meets internationally recognized food-grade directives (including FDA guidelines and European Union packaging standards).
Modern product preservation demands optimized barrier metrics (Oxygen Transmission Rate - OTR; Water Vapor Transmission Rate - WVTR). By formulating high-density composite laminations containing oriented polyester (PET), biaxially oriented polyamide (BOPA/Nylon), aluminum foil (AL), metalized cast polypropylene (MCPP), and linear low-density polyethylene (LLDPE) sealants, we optimize the shelf life of food, pharmaceutical, and technical chemical formulations under extreme climatic variables.
Translating chemical barrier properties into long-term preservation parameters.
Providing specialized materials tailored to specific chemical profiles, such as acidic sauces, oily dry food, and abrasive fine powders. We custom laminate PET, AL, NY, and PE layers to match exact physical demands.
Utilizing high-performance foil barrier films and EVOH co-extrusions to drive OTR and WVTR to near-zero levels, preventing rancidity, flavor loss, and clumping in hygroscopic powders.
Our film rolls feature consistent slip additives (COF), ensuring seamless performance in high-speed form-fill-seal operations without jaw-sticking or tracking deviations.
| Material Configuration | Primary Target Market | OTR Performance (cc/m²/24hr) | WVTR Performance (g/m²/24hr) | Key Strengths & Properties |
|---|---|---|---|---|

| BOPP / VM-PET / LLDPE | Extruded Snacks, Puffed Chips, Crisps | < 1.0 | < 0.5 | Strong moisture protection, high tensile rigidity, and premium display metallization. |
| BOPA (Nylon) / LLDPE | Heavy Pet Dry Kibble, Deep Frozen Liquid | < 30.0 | < 5.0 | Excellent puncture, drop, and burst strength. Ideal for vacuum processing. |
| PET / BOPA / R-CPP (Retort) | Sterilized Wet Pet Foods, Ready Meals | < 1.5 | < 1.0 | Withstands high-temperature thermal retort cycles up to 121°C. |
Yuanzhong's Industrial Ecosystem and Cost-Efficiencies
Southern China—specifically Guangdong Province—remains the epicenter of global packaging manufacturing, chemical processing, and supply-chain logistics. By positioning our primary manufacturing plant in Jieyang City, Guangdong, Yuanzhong Printing draws directly upon established logistical links, local chemical raw material production (polyolefin resins, PET masterbatches, polyurethane adhesives), and local machinery engineering talent. This integration translates directly into pricing structures, minimized transport overhead, and shortened lead times for our overseas procurement partners.
In addition to our physical location, our facility features Japan Komori fully automatic printing production lines. These systems represent the pinnacle of offset-rotogravure engineering. Their automated registration control systems continuously scan running webs, correcting minor micro-step misalignments in real time. This keeps dot gain low, color matching precise, and print speeds exceptionally high. Combined with local Chinese high-speed solventless lamination processes, we drastically reduce volatile organic compound (VOC) emissions, producing clean, low-odor, food-safe packaging materials.
High-precision gravure technology ensuring thick ink coverage, color saturation, plate durability, and stable print runs.
High-barrier architectures tailored to diverse global industry standards.
No single packaging laminate works for all applications. Modern food brands, cosmetic packagers, agricultural distributors, and pet food companies face distinct regulatory environments and preservation challenges. To solve these needs, we formulate solutions for four core industry clusters:
Dry pet kibble and organic treats require packaging structures that block moisture and light while containing natural fats and aromatic compounds. Our multi-layer, flat-bottom pouches with heavy-duty side gussets and press-to-close zippers are designed to prevent oil migration, keeping dry food fresh and aromatic over long storage cycles.
Potato chips, corn puffs, and nuts are susceptible to oxidation. Using high-speed nitrogen flushing lines, we supply form-fill-seal film rolls featuring VM-PET layers. These maintain an internal gas headspace, keeping products crisp and fresh while avoiding grease-leakage and physical crushing during transit.
Ground coffee releases CO2 gas and must be protected from oxygen exposure. We manufacture thick, food-grade plastic laminate films equipped with degassing valve integration. This layout permits gas evacuation without introducing external oxygen, preserving delicate volatiles and aromas.
Resealable spouted pouches require excellent seal integrity to prevent leakage under pressure. By incorporating high-performance linear low-density polyethylene (LLDPE) sealants, our liquid and paste pouches handle impact drop-tests and physical stress, providing a durable alternative to glass or rigid plastic jars.
Collaborating with more than 20 brands and serving clients in 10+ countries through continuous innovation.
A testament to our commitment to excellence in the flexible packaging industry.
















Meeting Global Mandates for Circular Economies and Reduced Environmental Impact
The global packaging sector is undergoing a major structural shift toward environmental responsibility. Key consumer markets, including the EU, North America, and parts of the Asia-Pacific region, have implemented strict plastics legislation and producer-responsibility mandates. These rules are driving brands away from legacy, non-recyclable multi-material laminate configurations. As a leading OEM Flexible Packaging Co Manufacturer & Supplier, Yuanzhong is actively developing high-barrier, mono-material structures (such as Oriented PE paired with barrier PE coatings) and compostable, bio-based films.
These mono-material packages are designed to go straight into existing municipal PE recycling streams. They reduce waste fees for brands while matching the oxygen and moisture barrier protection of standard multi-material films. Our solventless lamination machinery keeps laminating adhesive use low, resulting in pouches with minimal residual solvents. This profile matches strict food contact parameters and keeps the finished package free of chemical odor.
By partnering with Yuanzhong Pack, international procurement offices gain access to raw materials and processing structures designed to meet upcoming international environmental compliance standards. This reduces the risk of import delays or non-compliance penalties at global points of entry.
