Over Two Decades of Flexible Packaging & OEM Printing Mastery
Jieyang Yuanzhong Printing Co., Ltd. is a prominent leader in the global packaging and printing industry. Established in 2001 and situated in the Jiedong District of Jieyang City, Guangdong Province, China, our private enterprise boasts over 20 years of relentless innovation and specialized printing expertise. We provide high-end, customized plastic packaging bags and laminated barrier films designed to meet the rigorous demands of food, industrial, and specialized chemical sectors.
Our expansive, modern facility operates under strict quality management systems and houses advanced machinery, including imported Japan Komori fully automatic printing production lines. This engineering integration enables us to achieve a steady, high-precision monthly output exceeding 240 tons, ensuring unmatched scalability and short lead times for our diverse global customer base.
What sets Yuanzhong Packaging apart is our customized development capabilities. We recognize that industrial packaging demands vary by chemical reactivity, product state, and shelf environment. Our engineering teams work hand-in-hand with brand managers and procurement departments worldwide to design, test, and manufacture composite materials tailored for specific moisture barriers, UV resistance, and chemical containment properties.
High-barrier packaging specifications for chemical containment, foods, and agricultural powders
| Material Laminate Structure | Typical Thickness Range | OTR (Oxygen Transmission) | MVTR (Moisture Transmission) | Primary Industrial Applications |
|---|---|---|---|---|
| PET / AL / LLDPE | 80 - 150 microns | < 0.05 cc/m²/24h | < 0.05 g/m²/24h | Chemical Powders, Agrochemicals, Coffee, Milk Powder |
| PET / BOPA (Nylon) / PE | 90 - 180 microns | < 15.0 cc/m²/24h | < 1.5 g/m²/24h | High-Puncture Strength Bags, Industrial Liquids, Wet Pouches |
| PET / VMPET / LLDPE | 70 - 120 microns | < 1.0 cc/m²/24h | < 0.8 g/m²/24h | Snack Food Rollstocks, Detergents, Dry Chemical Mixes |
| Monomaterial PP (BOPE/MDO-PE) | 80 - 140 microns | < 2.5 cc/m²/24h | < 1.2 g/m²/24h | Eco-Friendly Recyclable Packaging, General Detergents |
Engineering Note: Chemical compatibility testing is highly recommended for strong acidic, alkaline, or volatile organic compounds to determine the optimal inert layer (typically specialized linear low-density polyethylene blends or cast polypropylene co-polymers).
Precision manufacturing stages backed by gravure printing excellence and high plate durability
As a leading printing technology, gravure printing occupies an extremely important position in the fields of food-grade packaging and chemical bagging. The process delivers thick ink layers, vibrant colors, high saturation, and fast printing speeds. The high plate durability makes it cost-effective for large-volume OEM production runs, providing consistent output across millions of impressions.
Once printing is complete, the substrate undergoes composite lamination, where multiple film layers (PET, AL, Nylon, PE) are bonded together using solvent-free adhesive technology. The laminated material is then processed through high-speed slitting machines to achieve exact roll width specs, after which it enters the bagging department for converting into stand-up pouches, flat pouches, or 3-side seal configurations before final industrial packaging and shipment.
Integrating digital manufacturing with raw material supply security for global OEMs
Equipped with Japan Komori production lines and high-precision gravure stations, our processes are heavily automated to minimize human error, reduce scrap rates, and maintain consistency in seal strength and dimensional tolerances.
By leveraging close regional proximity to base chemical and polymer raw material suppliers in southern China, we secure consistent film supplies at optimized price-to-performance levels, insulating clients from supply spikes.
Every packaging batch undergoes strict validation, including drop testing, heat seal integrity testing, gas chromatography (to verify minimal solvent retention), and tensile elongation checks to ensure zero-leak performance.
Aligning with local environmental regulations and strict chemical safety standards
Modern packaging requires strict adherence to international safety policies. For agrochemicals, dry chemicals, and household cleaning concentrates, packaging materials must be chemically inert and resilient to stress cracking. Jieyang Yuanzhong Printing Co., Ltd. monitors developments under European REACH standards, US FDA food contact guidelines (essential for milk powders and coffee packaging), and regional VOC (Volatile Organic Compounds) control measures.
In response to international demand for circular economies, our technical roadmap focuses on the deployment of mono-material packaging (all-polyethylene structure laminates). Traditionally, composite films utilizing dissimilar layers (like PET bonded with Aluminum and LLDPE) present recycling difficulties. By stretching and processing high-density PE into BOPE/MDO-PE and laminating it with specialized sealant PE, we deliver high barrier performance without compromising recyclability.
Moreover, our future design initiatives are exploring bio-based barrier coatings and light-shielding non-foil laminates, which offer comparable moisture barriers to traditional aluminum foil while reducing the carbon footprint of production and transportation.

Technical answers to critical packaging, chemistry compatibility, and factory logistics questions
We evaluate chemical resistance by analyzing the active compounds in your product. For corrosive or volatile contents, we recommend laminates incorporating high-density PE, BOPA (Nylon), or aluminum foil, which acts as a total block barrier. We also conduct environmental stress cracking resistance (ESCR) and temperature-cycle storage tests to confirm that the heat-seal layers and adhesives remain chemically inert.
Standard OEM production cycles run between 15 to 25 working days. This timeframe covers gravure plate cylinder engraving, high-speed printing, multi-layer composite lamination, oven curing (necessary for structural bonding), slitting, and bag fabrication. Emergency replenishment runs can be optimized through our ERP planning systems for established partners.
Yes, our food-grade packaging lines (such as packaging for milk powder, snacks, and turkey) strictly utilize raw materials compliant with FDA Title 21 CFR and EU Food Contact Regulation No. 10/2011. We compile and issue Declarations of Compliance (DoC) and coordinate with third-party testing labs like SGS and TÜV for formal validation.
MOQ typically depends on the width and formulation of the film, generally starting from 500 kg per design. Because our gravure presses run at speeds up to 200m/min, this minimum is required to minimize setup waste and ensure cost-efficient color consistency.
