In the highly regulated food sector, the integrity of a package's seal dictates the longevity of its contents. Custom sealable food packaging systems operate at the critical intersection of material science, mechanical optimization, and environmental responsibility. For global procurement officers and brands, selecting an authoritative manufacturing partner is not simply about acquiring plastic film; it is about guaranteeing food safety, mitigating supply chain waste, and complying with ever-evolving global regulatory requirements.
Jieyang Yuanzhong Printing Co., Ltd. (Yuanzhong Pack) manufactures high-performance barrier packaging. We customize heat-sealable films, stand-up pouches, and roll stock to perform consistently on high-speed vertical form-fill-seal (VFFS) and horizontal form-fill-seal (HFFS) packaging lines.
Engineered multi-layer films and premade pouches optimized for automated filling, superior barrier defense, and seal security.
Modern food production lines operate under narrow margins and strict shelf-life requirements. Selecting custom packaging requires analyzing how materials behave under thermal stress, mechanical pressure, and environmental changes during transport.
Single-polymer plastics rarely offer the protection needed for sensitive foods. We design complex laminated roll stock containing PET for structural stiffness and tensile strength, EVOH or Aluminum Foil for barrier security against gas ingress, and PE or Surlyn for a reliable low-temperature sealant layer.
Powder and grease contamination on sealing surfaces can lead to micro-leaks. By formulating custom co-polymer sealant layers, our pouch materials flow around particulates during the heat-sealing cycle, ensuring a secure, continuous hermetic bond even in high-dust filling environments.
Global retailers are moving away from mixed-material packaging to improve circularity. We offer BOPE/PE structures that match the barrier performance and tensile stiffness of traditional PET/PE laminates, allowing brands to implement fully recyclable packaging on existing machinery.
Established in 2001 in the Jiedong District of Jieyang City, Guangdong Province, Jieyang Yuanzhong Printing Co., Ltd. (Yuanzhong Pack) is a private manufacturing enterprise specializing in high-performance flexible packaging. With over two decades of production experience, we specialize in high-definition gravure printing and the conversion of custom sealable food-grade plastic packaging bags.
Our production facility is equipped with automated manufacturing lines, featuring Japan Komori automatic offset printing systems and high-speed gravure lines. This machinery allows us to maintain a monthly output exceeding 240 metric tons, providing dependable lead times and scaling capacity for large B2B orders.
At Yuanzhong Pack, customization is integrated into every step of our process. We formulate structures, film thickness, barrier characteristics, and dimensions to meet the unique requirements of our global partners. Operating a reliable export network, we provide products to clients in over 30 countries across North America, Europe, Oceania, and Southeast Asia.
Gravure printing remains the industry standard for high-volume flexible packaging due to its deep ink laydown, color saturation, high cylinder durability, consistent print quality, and stable high-speed run times.
High-definition rotary gravure printing on face films at high line speeds.
Solvent-free dry lamination bonding the outer, barrier, and sealant webs.
Slitting master rolls down to the target widths required for VFFS/HFFS lines.
Converting laminated rolls into premade pouches (spouted, stand-up, Doypack).
Inspection, count verification, and dust-proof packaging for secure transit.
Navigating international customs and food contact regulations requires systematic documentation and testing. We ensure that our materials and processes comply with strict global safety frameworks.
All food-contact laminates and resins comply with FDA 21 CFR regulations for direct food contact and EU Commission Regulation No 10/2011 concerning plastic materials. This compliance mitigates migration risks and supports compliance for regional distributors.
We maintain batch traceability from raw polymer resin and adhesive components through to the shipped container. Every production run is documented with raw material certificates and retention samples, providing transparency for corporate supply chain audits.
Our logistics support includes customs preparation, container configuration optimization, and heavy-gauge protective transit packaging. This ensures that rolls and pouches arrive at customer processing facilities undamaged and ready for immediate loading.
Different foods present distinct chemical properties, moisture levels, and physical profiles. We tailor material configurations to address the specific deterioration vectors of each product class.
High susceptibility to oxidation and moisture pick-up causing clumping. We utilize PET/AL/PE or metallized PET structures to achieve near-zero OTR (Oxygen Transmission Rate) and WVTR (Water Vapor Transmission Rate).
Requires puncture resistance to withstand dry kibble abrasion and oil barrier properties to prevent grease leaching. Standard laminates feature heavy-gauge PET, Nylon, and custom-modified PE sealant webs.
Requires high-strength seals to prevent leaks during drop impacts. We produce specialized spout pouch laminations that resist thermal sealing stress and are compatible with hot-filling systems.
Requires high-speed sealing properties and oil resistance. We formulate packaging rolls with BOPP/VMCPP or PET/VMPET/PE to preserve freshness and support clean sealing on high-speed horizontal lines.

As environmental targets approach, the flexible packaging industry is undergoing significant technological changes. We are developing solutions focused on material reduction and recyclability.
Developing sealant resins that initiate seals at lower temperatures. This allows packaging lines to run faster, reduces thermal stress on film structures, and lowers operating energy consumption.
Developing fully recyclable, oriented Polyethylene (MDO-PE) films laminated to solvent-free PE sealants. This provides the barrier properties of multi-material laminates in a single-polymer structure that is compatible with current recycling streams.
Testing bio-based polymers (like PLA and PHA) laminated to biodegradable barrier coatings. These materials are designed to break down in industrial composting facilities while maintaining seal strength.

Frequently asked technical questions regarding film specifications, barrier characteristics, and ordering protocols.
A: For products sensitive to oxygen and moisture, we typically recommend a multi-layer structure incorporating Aluminum Foil (PET/AL/PE) or EVOH (PET/EVOH/PE). Aluminum foil provides a complete physical barrier to gases and light, while EVOH offers high oxygen barrier properties in a transparent format.
A: Our film rolls are formulated with controlled Coefficient of Friction (COF) values (typically between 0.15 and 0.25). This target range ensures smooth feeding, stable tension, and reliable tracking through vertical and horizontal form-fill-seal (VFFS/HFFS) packaging systems, helping to prevent wrap-ups or jams.
A: Yes, all polymer resins, dry laminating adhesives, and gravure inks utilized in our production are FDA-approved and comply with EU Regulation No 10/2011. We provide Declarations of Compliance (DoC) and migration test reports for regulatory documentation.
A: Standard production lead times are 15 to 25 days following artwork approval and cylinder engraving. MOQs are determined by material volume; for standard laminates, the minimum run is typically 500 kg of film web or 10,000 to 20,000 premade pouches, depending on size.
A: Yes, we manufacture fully recyclable mono-material structures (such as BOPE/PE laminates) that can be integrated into standard plastic recycling streams. We also offer compostable structures using PLA and paper materials for specific product applications.
