    25kg 50kg Cement Paper Bag Machine Valve Feed Sack Bag ...
    Paper-plastic composite valve sack machines are specialized industrial systems designed to produce durable, high-strength packaging for industries like cement, chemicals, and fertilizers. These machines, manufactured by companies like Fangbang Machinery, Yideng, Gachn Group, and Kxite, often utilize hot air welding or hot melt adhesives to combine kraft paper with woven PP/PE layers. They produce block-bottom valve bags, offering efficient filling, high strength, and moisture resistance, with production speeds often reaching 120–200+ bags per minute. 
    Key Manufacturers and Machine Types 
    • Gachn Group / JEENAR: Known for producing high-end, intelligent, automatic block-bottom valve bag machines that handle PP, PE, and paper-plastic composites.
    • Foshan Tecon Package Machinery (Youniker): Specializes in complete paper valve bag production lines, including tubers and bottomers for cement and dry mortar bags.
    • Fangbang Machinery: Manufactures FB-S120 NEW models for double-sided coated polypropylene tubes.
    • Kxite: Focuses on PP block-bottom valve bag machines using hot air welding technology. 
    Machine Capabilities and Features 
    • Material Compatibility: Processes paper-plastic compounds, single or multi-layer paper, and woven PP/PE.
    • Technology: Uses hot melt adhesive or hot air welding for sealing, ensuring superior strength.
    • Valve Types: Capable of producing internal and external valve options.
    • Automation: Modern, high-speed machines incorporate AI visual inspection, automatic tension control, and energy-saving technology.
    • Efficiency: Production speeds typically range from 80 to over 200 bags per minute. 
    Typical Production Line Configuration 
    A complete production line for paper-plastic composite valve sacks usually includes two main units: 
    1. Valve Sack Tuber: Creates the tube from raw material (paper/film).
    2. Valve Sack Bottomer: Forms the bottom and installs the valve, often with options for both-end or one-end pasting. 
    These machines are designed to produce, for example, 25kg to 50kg block-bottom bags that are ideal for automated filling lines.
