Discover our primary lineup of barrier films, customized rolls, and resealable stand-up pouches designed for high-speed automated filling lines.
In modern industrial operations, packaging functions as far more than a simple container. It is a critical sub-system designed to regulate atmosphere exposure, prevent chemical migration, protect mechanical integrity, and facilitate automated high-speed logistics. High-quality back packaging (commonly realized as center-sealed pouches, fin-seal bags, lap-seal laminates, and pillow packs) occupies the center stage of global product distribution. Manufacturers, processing plants, and consumer packaged goods (CPG) brands are shifting rapidly toward lightweight flexible barrier structures to reduce transportation costs, minimize carbon footprint, and meet rigorous global food contact standards.
The global market for flexible back packaging is marked by demands for high barrier properties (oxygen transmission rates - OTR, and water vapor transmission rates - WVTR approaching near-zero values), high tensile seal strength, and flawless runnability on Vertical Form Fill Seal (VFFS) and Horizontal Form Fill Seal (HFFS) automated machinery. As a veteran manufacturer, Jieyang Yuanzhong Printing Co., Ltd. has integrated raw materials formulation, high-precision rotogravure printing, solvent-free and dry lamination, and structural converting to provide dynamic back packaging solutions tailored for global supply chains.
Back-sealed pouches (also known as pillow pouches or T-seal bags) distribute seal stress along a central axis down the back of the package. This configuration offers superior seal strength for dry products, powders, and heavy items compared to side-weld equivalents, ensuring drop-test resistance and airtight storage.
We employ multi-layer co-extrusion and adhesive lamination methodologies to combine polymers with distinct thermal, mechanical, and barrier properties. The typical engineering configurations for high-performance back packaging include:
Features an aluminum foil core block layer. Eliminates UV light, oxygen, and moisture transmission. Ideal for milk powders, coffee, and sensitive medical items.
Provides excellent stiffness, brilliant metallic optical gloss, and solid barrier parameters. Best suited for high-speed potato chips packaging and snacks packaging.
Monomaterial polyolefin matrices (PE/PE or PP/PP) that allow single-stream recycling compliance while retaining high thermal seal reliability and tensile strength.
By adjusting material thickness (ranging from 40 microns up to 180 microns) and seal-layer formulation, we optimize coefficient of friction (COF) levels. This optimization ensures that our rollstock films glide smoothly through packaging collars and sealing jaws without film stretching or thermal burn-through.
Underpinned by high-precision gravure printing technologies, our production sequence delivers highly vibrant colors, thick ink layers, and mechanical stability.
Our facility in Jiedong District, Jieyang City utilizes advanced imported infrastructure including Japan Komori fully automatic printing production lines. With printing capabilities operating at high web speeds, we maintain an output capacity exceeding 240 tons monthly. The gravure printing method guarantees consistent, high-definition graphical replication, essential for consumer branding and industrial serialization.
Industrial packaging must adapt to the unique mechanical stresses and chemical interactions of different market segments. Our back-seal pouches and film structures are optimized for a wide array of commercial uses:
For snacks, potato chips, and chocolate, oxygen is the primary agent of degradation. Our metalized laminates maintain a modified atmosphere (nitrogen flushing) inside the bag, preserving crunchiness and flavor profiles. For liquid products like infant milk formula or pasteurized purees, we supply high-integrity films that prevent lipid oxidation and survive hot-fill processing temperatures.
Pet food matrices contain high fats and oils that can migrate through sub-standard plastics, causing grease staining and odor leakage. Our custom-printed pet food bags are engineered with specific grease-barrier layers (such as Nylon or specialized PET/PE blends) to prevent delamination and preserve nutritional values over prolonged warehouse shelf-lives.
Finely milled powders and dry coffee beans demand anti-static inner surfaces and degassing valve integrations. Our high-performance rolls prevent fine particles from sticking to the seal area during VFFS packaging, ensuring hermetic seal integrity.
As a global supplier exporting to more than 30 countries, Jieyang Yuanzhong Printing Co., Ltd. guarantees compliance with local food safety regulations, environmental directives, and customs protocols.
Exploring the World Through Exhibitions: A Journey Across More Than 10 Countries to present our latest flexible packaging breakthroughs.
The flexible packaging sector is undergoing a massive transformation driven by plastic reduction initiatives, extended producer responsibility (EPR) mandates, and consumer demand for transparency. Our technical roadmap highlights two major development pathways:
Historically, multi-layer films combining PET, Aluminum, and PE were impossible to recycle due to the difficulty of separating layers. We are engineering oriented PE (MDO-PE) and BOPP alternatives that simulate the mechanical properties of PET. These mono-polyolefin structures allow the final bag to be reprocessed in standard plastic recovery channels, reducing environmental waste.
We are actively testing PLA (polylactic acid), PBAT, and cellulose-based laminates. These bio-based films decompose in industrial composting conditions, offering an effective alternative for organic products, single-use bags, and localized dry food packaging.
Integrating high-density QR codes, RFID tags, and temperature-sensitive inks directly onto back packaging enables real-time tracking, batch verification, and anti-counterfeiting security across transcontinental logistics paths.
