Thanks for reaching out about the SJ Series — this line handles both PP and PET with extruder diameters ranging from 65 to 120mm, so it fits production scales.
It hits up to 260 meters per minute on strap widths form 5 to 32mm, and thicknesses between 0.35 and 1.2mm, which gives you real flexibility without swapping tooling. That camber staying under 20mm per two meters is a solid spec for straight runs.
Daily output sits around 5 to 6 tons when running four straps, and tensile strength can reach 12,000N on the 32 by 1.2mm size. Teh optional melting pump helps keep matrial flow consistent, which I find makes a noticeable difference on longer shifts.
Cooling is water-based and heating is electric, with a PLC control system managing everything. automatic screen changer is optional, but it does allow non-stop operation if you need it. Warranty runs one year, and lifetime techincal support is included after that.
Motor power varies from 37 to 110kW depending on the configuration you need, and you can set it for 2 to 8 straps at once. Let me know the exact output you're targeting so I can quote the right model.
Our MOQ is one complete set, so you can start with a single line and scale up later as your output needs grow.
Yes, we include factory test reports for tensile strength (up to 12000N at 32x1.2mm) and camber (under 20mm per 2 meters) with your shipment. Any extra certification needs can be arranged on request.
Typical lead time is 30 to 45 days for a standard SJ Series line. Installation and training usually take 5-7 days on-site, and we provide lifetime technical support if you run into any issues later.
Yes, the SJ Series is designed for both PP and PET materials. You just need to adjust the die and temperature settings — no heavy mechanical changes required.
It's an open-loop water cooling system, so you'll need a steady water supply and a drain connection. We can help you plan the setup if you need a recirculation option.
