High Tensile PP Strap Production Line

Product Overview

This production line is specifically engineered for manufacturing high-tensile-strength PP strapping. It incorporates a φ120mm 38CrMoAlA alloy steel screw with a 30:1 L/D ratio, ensuring thorough material plasticization. Combined with a 55KW high-efficiency main motor, it delivers maximum output of 220-240 kg/h. Through a multi-stage stretching process with an adjustable draw ratio of 1.5-12 times, PP molecular chains become highly oriented along the stretching direction, significantly increasing the longitudinal tensile strength of the final product. With maximum line speeds reaching 200 m/min, this system meets demanding large-volume, continuous production requirements.

Frequently Asked Questions

How is high tensile strength achieved?

Through a multi-stage stretching process with an adjustable draw ratio of 1.5-12 times, PP molecular chains become highly oriented, increasing tensile strength several times over. Users can flexibly choose the optimal draw ratio based on the final application requirements.

Does high output affect tensile strength?

No. The 38CrMoAlA alloy steel screw, 30:1 L/D ratio, and 9-zone independent temperature control (±1°C accuracy) ensure full plasticization. Both high output and high strength are achieved simultaneously without compromise.

What tensile strength can the strapping achieve?

Tensile strength varies by specification and draw ratio. For standard 12mm×0.6mm strapping at 8-10x draw ratio, breaking force can exceed 200kg. Actual values depend on specific product specifications and process settings.
