This curved heat-sealing bar is a bottom-sealing mold specifically designed for stand-up pouches, used for sealing the curved bottom of SUP. Made of aerospace-grade aluminum alloy, it features a mechanical locking mechanism. The bottom curvature and sealing edge dimensions can be customized. It provides uniform and stable heat conduction, ensuring continuous high-temperature sealing without bubbles or leakage. Suitable for various composite stand-up pouches for coffee, daily chemicals, and snacks, and compatible with fully automated high-speed bag-making production lines.
1.Developed and manufactured by a 30-year factory. It utilizes a complete Seibu wire EDM + CNC machining process, optimizing the heat sealing bar profile for high-barrier materials like aluminum foil, ensuring stable, leak-free sealing during long-term mass production.
2.Customizable to all sizes and curvatures, adaptable to various coffee bag specifications. Supports customization of bag opening curvature, sealing edge width, and overall machine length for different capacity coffee bags.
3.Constant temperature heat conduction ensures a strong, leak-free seal and long-lasting durability. Made of integrated aerospace-grade aluminum alloy, it provides even heat conduction without localized overheating; it is oxidation- and corrosion-resistant, allowing for continuous use on conventional production lines for many years without frequent blade replacements.
4.High-end processing equipment delivers superior quality compared to competitors. Utilizing Japanese Seibu wire EDM for cutting the sealing profile, combined with a CNC integrated milling die base, the profile is smooth and burr-free, resulting in a bubble-free and delamination-free seal.
This custom heat-sealing bar is compatible with a wide range of flexible packaging materials, offering excellent adaptability and compatibility. It can process PE, PO, PP, OPP, PVC, PPE, PPU, CPE, and LDPE plastic films, and is also suitable for various flexible materials such as aluminum foil composite bags. It supports custom sealing designs for straight edges, rounded edges, waves, and irregular shapes. All sealing dimensions and outlines can be customized to meet specific needs. It boasts high heat-sealing precision, resulting in smooth, tight, and uniform sealing effects.
It is widely used in the production of coffee powder bags, dried fruit and snack bags, laundry detergent, sauces, and fruit and vegetable preservation stand-up pouches. It is suitable for fully automated bag-making production lines in food, daily chemical, agricultural, and consumer goods packaging factories, responsible for the curved sealing of the bag bottom. The finished product has strong sealing performance and no leakage issues.
