Zhejiang Xifeng Packaging Co., Ltd.
Zhejiang Xifeng Packaging Co., Ltd. is located in Pingyang County, Wenzhou-known as China's "Capital of Plastic Woven Packaging." The company specializes in packaging for the animal feed industry and is a leading domestic manufacturer dedicated to the R&D, application, and promotion of color-printed woven bag technology. With fixed assets of 28 million RMB and a workforce of over 80 employees, the company achieves an annual output of 40 million woven bags and an annual production value exceeding 80 million RMB. It employs a centralized group procurement strategy and leverages internationally advanced systems for quality control, color management, and order review, supported by comprehensive testing procedures and a top-tier quality control team.
Milestones include: the completion of the first-generation factory in 2003; the integration of online and offline sales channels in 2005; the commencement of packaging bag exports in 2007; the development of over 100 types of packaging combinations in 2010; reaching an annual production capacity of 40 million color-printed bags in 2013; and the relocation to a new, standardized factory facility in 2017, at which time the company was officially renamed Zhejiang Xifeng Packaging Co., Ltd.
Our Factory
The facility features standard factory premises equipped with five computer-controlled rotogravure printing presses, two high-speed laminating machines, and a state-of-the-art laminator (featuring automatic computer-controlled alignment and a cooling system), alongside dedicated workshops for offset printing and bottom sealing. The printing presses support simultaneous front-and-back printing with a maximum width of 124 cm and automatic computer-controlled color registration, achieving an output of 8,000 to 12,000 meters per hour; the laminating equipment has a daily capacity of 200,000 meters.
Our Product
Packaging bags for livestock and poultry feed, aquaculture feed, and pet food (cat and dog food), as well as bags for other purposes (such as feed additives). Customization options include block-bottom bags, composite bags, and more.
Product Application
The woven bags manufactured by Zhejiang Xifeng are primarily designed to meet the comprehensive packaging needs of the feed industry. Specific applications include:
Livestock and Poultry Feed
Packaging for compound feed, concentrated feed, and premixes for pigs, chickens, ducks, cattle, and sheep. Bag types include block-bottom valve bags and sewn-bottom bags, designed to meet the requirements of high-speed automated filling lines.
01
Aquatic Feed
Specialized packaging for extruded and sinking feeds (e.g., for shrimp, fish, and crabs) that is moisture-proof, mold-resistant, and UV-resistant, ensuring structural integrity across diverse storage environments in both northern and southern regions.
02
Pet Food
Color-printed packaging for cat, dog, and small-pet food. Utilizing food-grade inks and lamination technology, these bags offer an attractive appearance and pleasant tactile feel, while providing excellent oxygen and moisture barrier properties to extend shelf life.
03
Feed Additives and Raw Materials
Suitable for packaging additives such as vitamins, minerals, and probiotics, as well as bulk raw materials like corn and soybean meal. Lamination or coating processes can be selected based on material characteristics to prevent leakage and contamination.
04
In addition, we offer customized functional packaging-such as anti-static, high-temperature resistant, and UV-resistant options-to meet specific client requirements, providing tailored, "one-solution-per-enterprise" strategies for various market segments.
Our Certificate
The company is ISO 9001 certified, and its products comply with the GB/T 8946-2013 standard ("General Technical Requirements for Plastic Woven Bags") as well as relevant export standards. We use eco-friendly, water-based inks for color printing that meet RoHS and REACH requirements. Additionally, we hold multiple utility model patents for improvements in woven bag manufacturing processes. Color samples from every batch are retained for reference to ensure color consistency; products undergo regular third-party testing for parameters such as tensile strength, drop performance, and heat resistance, with test reports available upon request.
Production Equipment
Our production equipment is characterized by automation, high precision, and low material loss. Key equipment includes:
Computerized Rotogravure Printing Machines (5 units): Feature a maximum printing width of 124cm and support simultaneous front-and-back printing to eliminate color discrepancies. Equipped with automatic computerized registration systems, they maintain registration accuracy within ±0.2mm and achieve printing speeds of 8,000–12,000 meters per hour, delivering crisp patterns and rich colors.
High-Speed Lamination Machines (2 units): Used for the woven bag lamination process, these machines feature automatic computerized alignment; they trigger an alarm and automatically correct errors if the front-to-back alignment deviation exceeds 0.5cm. An integrated cooling and setting system cools the material immediately after lamination to prevent subsequent wrinkling or shrinkage, achieving a daily production capacity of 200,000 meters.
Fully Automatic Film Reversing/ Rewinding Machine: Operates in conjunction with printing machines to slit and rewind film after double-sided printing. It supports roll lengths of up to 20,000 meters, significantly reducing the number of splices, lowering defect rates, and enhancing efficiency in downstream processes.
Offset Printing Machine: Suitable for the rapid printing of simple text or single-color logos, offering flexibility for small-batch or top-up orders.
Fully Automatic Bottom Sealing Machine: Enables mass production using various sealing methods-such as stitching or heat sealing-ensuring flat, secure bag bottoms that meet the requirements of fully automated packaging lines.
Color-Printed Film Reference Archive: Retains samples of the initial print run for every new design to serve as a benchmark for color comparison in subsequent batches, ensuring consistent color quality over long-term supply.
All equipment undergoes regular maintenance and calibration, with in-line inspection points established at critical process stages to ensure strict process control.
Production Market
Our company focuses primarily on the domestic market while maintaining an export presence. Our key markets are distributed as follows:
