Knotless raschel nets-produced on a knotless net machine-are widely used for bagging onions, garlic, citrus, potatoes, and carrots, as well as for protective sleeve nets and bird-protection fencing. Unlike knotted nets, a knotless net machine weaves smooth, snag-free meshes with high tensile strength and uniform open areas, making them ideal for both packing and display purposes.
A typical knotless net machine is a Raschel warp-knitting machine fed by extruded PP or PE monofilament/yarn. Key specs to compare: working width (usually 120–260 cm), gauge (E6–E16), number of guide bars (2–4), and maximum knitting speed (RPM). A versatile knotless net machine accepts both virgin and recycled PP/PE yarns, letting you balance cost and mesh stiffness.
Mesh size and shape are controlled by chain link pattern and take-up ratio. Quality knotless net machine models allow quick pattern change via interchangeable pattern chains or electronic jacquard, so one line can produce fine mesh for shrimp/citrus bags and coarse mesh for vegetable sacks. Tension control for warp & weft beams is critical-uneven tension causes distorted meshes and wasted yarn.
Buyers should also assess: (1) Brand of main drive & PLC (Siemens, Yaskawa, etc. preferred); (2) Ease of threading and maintenance-open-design knotless net machine frames simplify cleaning; (3) Spare parts package-extra needles, sinkers, pattern chains; (4) Supplier support-installation, yarn tension tuning, and pattern programming training.
Energy use per meter is low, but downtime is expensive. Choose a knotless net machine from a manufacturer with proven export references and a clear warranty policy. Many agro-packagers start with a single knotless net machine plus an extrusion line for yarn, then scale up as bag demand grows.
In conclusion, a well-selected knotless net machine opens opportunities in food packaging, agriculture, and horticulture netting markets.
