Ultrasonic Seed Bag Machine for Agriculture Nursery
✔ Eco-Friendly Ultrasonic Sealing: Utilizes high-frequency ultrasonic welding to create strong, glue-free seams perfectly suited for biodegradable seedling bags.
✔ Turntable Interlocking Design: Features an advanced mechanical turntable for precise edge wrapping and 3D gusset forming, maximizing soil capacity.
✔ High-Speed Efficiency: Maintains a continuous and stable production rate of 100 PCS/MIN, ideal for bulk agricultural supply.
✔ Smart Web Guiding: Equipped with an automatic cylinder-driven tension control system to handle non-woven rolls smoothly without stretching.
Modern agriculture and forestry are rapidly shifting away from plastic pots toward sustainable, root-friendly plant raising solutions. This high-efficiency seedling bag making machine is an advanced industrial converting system engineered to mass-produce these eco-friendly nursery bags. By utilizing high-frequency ultrasonic technology and an automated mechanical turntable, this non-woven seedling bag making machine shapes, welds, and cuts non-woven fabrics into perfect 3D soil bags at a continuous speed of 100 pieces per minute, fulfilling the immense demands of the global agricultural sector.
Glue-Free Ultrasonic Sealing: Designed as a premium ultrasonic biodegradable bag machine, it uses acoustic vibrations to fuse the non-woven fabric. This eliminates toxic adhesives, ensuring the bag remains 100% eco-friendly and safe for soil degradation.
Turntable Interlocking Formation: Rather than producing flat 2D pouches, the machine features a specialized turntable interlocking and wrapping mechanism. This creates a sturdy, gusseted bottom (3D structure) that allows the bag to stand upright when filled with soil.
High-Speed Output (100 PCS/MIN): A stable, high-yield production rate is critical for agricultural consumable suppliers. The automated cylinder-driven tension control ensures the non-woven web feeds smoothly without stretching or tearing during high-speed runs.
Automated Efficiency: Functioning as a fully automatic nursery bag making machine, it seamlessly executes longitudinal folding, ultrasonic sealing, edge wrapping, and transversal cutting. The finished products are neatly collected via a rotating windmill mechanism.

Non-woven seedling bags allow plant roots to penetrate the fabric easily, preventing root tangling and eliminating the need to remove the bag during transplanting. These bags are widely used in:
Agriculture & Greenhouses: Raising vegetable, fruit, and cash crop seedlings with higher survival rates upon soil transplantation.
Forestry & Reforestation: Cultivating saplings for large-scale tree planting projects, where biodegradable bags decompose naturally into the earth.
Commercial Floral Nurseries: Growing ornamental plants and flowers in a sustainable, breathable, and water-permeable medium.
- Packaging: Anti-rust treatment + Vacuum film + Fumigation-free Plywood Case.
- Warranty: 12-Month mechanical parts warranty.
- Installation: Detailed video tutorials provided. On-site engineer dispatch available upon request.






By partnering with an expert, source-level seedling bag making machine manufacturer like JUJIN, you eliminate trading company markups and secure highly competitive factory-direct pricing. Forming 3D agricultural bags at high speeds requires exceptional mechanical coordination. Our robust machine design, featuring precision ultrasonic welding and reliable cylinder-driven tension control, guarantees smooth operation and structural integrity, delivering a fast and highly profitable return on investment for your consumable business.
Q: Why use non-woven fabric instead of plastic for seedling bags?
A: Non-woven fabric is breathable, permeable, and biodegradable. It allows plant roots to grow right through the bag, preventing the "root bound" effect caused by plastic pots. When transplanting, the entire bag is buried and naturally degrades in the soil, saving massive amounts of labor.
Q: Can this machine produce bags of different sizes?
A: Yes. The machine is engineered to produce standard nursery bags with a length range of 100-120mm and a width range of 120-150mm. Specifications within this range can be easily adjusted via the touchscreen interface.
Q: Does the ultrasonic welding weaken the bag?
A: No, the opposite is true. High-frequency ultrasonic welding physically fuses the non-woven fibers together, creating a seam that is often stronger than the fabric itself, easily capable of holding densely packed soil without bursting.
