High-barrier films, protective pouches, and high-speed automatic roll stocks custom engineered to protect brand equity and extend product shelf-life.
Established in 2001 and situated within the highly active industrial zone of Jiedong District, Jieyang City, Guangdong Province, Jieyang Yuanzhong Printing Co., Ltd. has developed into a leading, technology-driven enterprise specializing in packaging decoration printing and high-grade flexible plastic packaging conversion. With over two decades of engineering and manufacturing expertise, we focus on delivering functional, customized flexible packaging films and pre-formed pouch solutions to global consumer brands.
Yuanzhong Pack operates dynamic clean-room production facilities featuring sophisticated machinery, including Japanese Komori fully automatic offset printing lines and high-speed rotogravure conversion machinery. Achieving a steady monthly output capacity exceeding 240 metric tons, we efficiently service complex batch requirements, maintaining stringent quality controls over material properties, solvent residuals, and structural seal integrity. Our business operates across 30 countries, optimizing brand value on retail shelves worldwide.
Analytical insights into polymer chemistry, regulatory compliance, and mechanical properties of advanced flexible laminates.
The global plastic packaging and printing industry is experiencing an accelerated transition driven by circular economy mandates and strict regional waste regulations (such as the EU's Packaging and Packaging Waste Regulation - PPWR). Historically, multi-layer films relied on complex, multi-polymer laminates (e.g., PET/AL/PE or BOPA/PE) to achieve the necessary gas, light, and moisture barrier properties. However, these mixed materials pose significant challenges for modern mechanical recycling streams.
To address this, our research and development focuses on monomaterial laminates (specifically PP/PP or PE/PE structures). By employing advanced Biaxially Oriented Polyethylene (BOPE) combined with high-barrier coatings like AlOx (Aluminum Oxide), SiOx (Silicon Oxide), or ultra-thin EVOH (Ethylene Vinyl Alcohol) layers (representing less than 5% of the total laminate weight), we achieve target Water Vapor Transmission Rates (WVTR) and Oxygen Transmission Rates (OTR) without compromising recyclability. This transition allows brands to fulfill international PCR (Post-Consumer Recycled) packaging mandates while ensuring food contact safety.
Engineering robust polymer structures requires careful calibration of density, crystallization, and tensile modulus. Each material in a laminate stack plays a critical functional role:
How Jieyang Yuanzhong Printing converts raw polymers into certified high-barrier commercial packaging materials.
Gravure printing remains a preferred method for high-volume flexible packaging due to its deep ink transfer, high saturation, and consistent quality over long production runs. Precision-engraved copper cylinders transfer ink directly onto the substrate web at speeds of up to 300 meters per minute. The system integrates real-time video inspection and auto-registration systems to keep color variation below ΔE = 1.5.
Following printing, the composite step uses solvent-free lamination technology. By curing solventless polyurethane adhesives at controlled temperatures, we prevent volatile organic compound (VOC) migration and eliminate solvent odors. This guarantees that finished pouches comply fully with FDA, EC, and GB regulations for direct food contact.
Strategic directions in active barrier systems, digital integration, and circular polymers.
Future packaging designs will offer capabilities beyond containment and preservation. We are currently testing functional coatings containing active oxygen scavengers and moisture-absorbent polymer compounds directly within the sealant layers. This active packaging actively extends the shelf-life of oxygen-sensitive foods like milk powder and protein shakes, reducing waste throughout the supply chain.
Additionally, we integrate digital features such as high-density QR codes and RFIDs into the print layers. These enable batch tracking, authenticate premium brands, and help consumers access recycling information easily.
For brands targeting plastic-free packaging, we provide certified compostable laminate options. By layering high-barrier cellulose films (derived from FSC-certified wood pulp) with PLA (Polylactic Acid) or PBAT (Polybutylene Adipate Terephthalate) heat-sealable films, we create packaging that breaks down completely in industrial composting facilities. These materials meet the requirements of ASTM D6400 and EN 13432 standards.
We continue to refine the oxygen and moisture barriers of these compostable structures, ensuring they match the performance of traditional petroleum-based polymers.
Tailoring material structures and performance characteristics to specific market applications.
Pet foods require packaging that prevents oil staining and resists punctures. We construct flat-bottom and quad-seal stand-up pouches using PET/AL/BOPA/LLDPE laminate structures. These materials protect fats and oils from oxidation and stop odors from escaping, while offering excellent drop resistance for heavier weights.
Nutritional powders are highly sensitive to oxygen and moisture. To protect them, we use thick aluminum barrier laminates (PET/AL/PE) or high-barrier metallized structures (PET/VMPET/PE). We also utilize anti-static sealant films to prevent powder from sticking to the seal area during high-speed filling.
Replacing rigid bottles, our spouted pouches for beverages and purees are designed to withstand high-temperature hot-filling or pasteurization (up to 121°C). The customized corners and reinforced heat-seals prevent leakage under pressure, making them highly cost-effective to ship.
