View Product DetailsEstablished in 2001 in the Jiedong District of Jieyang City, Guangdong Province, Jieyang Yuanzhong Printing Co., Ltd. (Yuanzhong Pack) has grown into a leading private enterprise specializing in packaging decoration printing and plastic packaging bag manufacturing.
With over two decades of processing experience, our production infrastructure utilizes advanced machinery, including fully automatic printing production lines from Komori, Japan. We maintain a steady monthly output capacity exceeding 240 tons, ensuring that we satisfy the high volume demands of dynamic global brands while preserving precision down to the micro-level.
By centering our operations on tailored customization (ODM & OEM), we support food, medical, cosmetic, and chemical companies with bespoke material formulations, exact dimensions, and specialized barrier films configured to protect product integrity.
Managing structural integrity, safety standards, and performance consistency across international supply chains.
Modern B2B buyers require packaging seals that prevent oxidization and microbial intrusion. We control OTR (Oxygen Transmission Rate) and MVTR (Moisture Vapor Transmission Rate) through co-extruded foil laminates designed for volatile substances, food powders, and infant nutrition.
Preventing transport failures, pouch bursting, and micro-leaks. Our packaging seals undergo strict peel-testing, bursting pressure evaluation, and heat-seal threshold verification to guarantee seal safety under fluctuating atmospheric conditions during transit.
Sourcing materials that meet strict FDA, EC, and localized environmental regulations. Yuanzhong Pack only sources raw polymers, resins, and solvent-free adhesive compounds from audited global chemical manufacturers, ensuring zero dangerous chemical migration.
Adapting polymer sciences and customized barrier structures to target the functional needs of diverse global industries.
Products like baby milk powder, protein supplements, and coffee beans demand strict ambient isolation. Our multi-layer structures (e.g., PET/AL/PE, PET/VMPET/PE) block UV rays, oxygen, and moisture to preserve organic qualities and extend shelf-life.
Alcohol-impregnated medical pads, hygiene swabs, and surgical instruments require completely stable sterile barriers. We formulate custom films resistant to corrosive compounds like isopropyl alcohol and ethanol, maintaining physical seal strength over multi-year cycles.
For food processors utilizing fast automated pouch-filling machinery, our roll stock films are finished with low CoF (Coefficient of Friction) coatings. This ensures stable web movement, prevents static build-up, and ensures immediate hermetic seals at lower jaw temperatures.
Combining function with visual appeal. Our Japanese Komori printing technology allows high-definition, high-saturation graphics, spot-UV treatments, and matte/gloss contrast layers to establish maximum shelf presence and consumer trust.
Gravure technology stands at the center of high-performance flexible packaging. The high ink-layer density, color saturation, plate durability, and stable print control ensure exact replica packaging over massive print runs.
As a pioneering ODM factory, we continuously invest in research and development to align with circular economy metrics and intelligent packaging requirements.
Transitioning multi-layer composites to recyclable mono-PE and mono-PP laminated structures that match original barrier capabilities, satisfying municipal collection protocols.
Integrating certified PLA, PBAT, and kraft paper combinations with cellulose barrier skins, providing high barrier performance while naturally decomposing within municipal compost conditions.
Embedding temperature indicators, RFID tags, and printed QR-codes to support real-time cargo tracing, anti-counterfeit protocols, and freshness tracking for consumers.
Upgrading our Chinese factory workflows to support water-based ink configurations and solvent-free composite lamination, guaranteeing zero residue in downstream packaging.
Sharing our custom engineering capabilities on global stages across more than 10 countries.
Cooperating with more than 20 leading international brands — a testament to our ongoing commitment to packaging and print excellence.
Selling flexible packaging films in international jurisdictions requires deep compliance structures. Yuanzhong Printing supports all major international markets, helping logistics teams cross customs checkpoints without documentation delays.
All chemical inputs, pigment dyes, and plastic materials comply directly with FDA (Food and Drug Administration) requirements, EU Directive 10/2011 for plastic items meant for food contact, REACH and RoHS regulations, and regional compliance structures.
By integrating specialized moisture and gas barriers, our structural custom designs extend ambient product shelf life, lowering transport damage margins while meeting localized eco-tax compliance initiatives (such as German Packaging Act / VerpackG, UK Plastic Packaging Tax).
Our logistics teams organize multi-modal delivery options, ranging from port-to-port maritime freight to regional door-to-door delivery setups.
Every manufacturing batch receives traceability metrics, including roll-specific QC analysis sheets detailing seal strength, thickness variance profiles, and residue testing results, ensuring transparent oversight of B2B production lines.

Heat seal strength depends on sealing temperature, pressure, and contact dwell time. Choosing appropriate inner polymer films (such as Linear Low-Density Polyethylene - LLDPE, or Cast Polypropylene - CPP) with custom seal temperature thresholds ensures secure sealing under varying high-speed packaging conditions.
We test film compositions using modern Permeation Analyzers to determine absolute Oxygen Transmission Rates (OTR) and Water Vapor Transmission Rates (WVTR). For products like infant formula or ground coffee, we combine aluminum foil (AL) or metalized polyester (VMPET) layers to keep gas/moisture entry close to zero.
Minimum order quantities depend on specific package sizing, structural formulas, and width profiles. Standard custom rollstock film configurations start around 500 kg per printing layout to optimize film usage on our high-speed Japanese Komori printing machinery.
Yes. Packaging materials containing high levels of isopropyl or ethyl alcohol can degrade common adhesives and plastic layers over time. We utilize specialty, solvent-free polyurethane laminating adhesives and chemically-resistant co-polymer heat-seal films to prevent package swelling, leaking, and de-lamination.
Our manufacturing and processing environments satisfy ISO 9001 quality guidelines. We ensure all polymers, pigments, and raw supplies pass international FDA food contact certifications, EU food contact guidelines, and environmental requirements like RoHS.
Gravure printing uses engraved metal cylinders that provide exceptional ink-layer thickness, intense color saturation, and unmatched durability. While cylinder setup costs are higher, gravure provides unmatched consistency over millions of impressions, making it the most cost-effective printing method for large-scale branding campaigns.
