Adjustable Draw Ratio 1.5-12 for High-Strength PP Strapping Line
High-Strength Stretching Orientation Technology

Stretching orientation is the core process for imparting high strength to PP strapping. The extension box and pressure extension unit of this production line provide a wide draw ratio adjustment range from 1.5 to 12 times. The extension box has a total length of 6.5 meters (4m + 2.5m), with φ200mm extension rollers at HRC60 hardness, heating power of 41.6KW, a 6KW mold temperature controller for precise roller temperature, and 100mm insulation. The pressure extension unit has a φ156mm roller and a 7.5KW motor. By precisely controlling the speed ratio between the extension rollers and haul-off rollers, PP molecular chains are highly oriented along the stretching direction, increasing the longitudinal tensile strength of the product several times over its unoriented state. Users can flexibly select the optimal draw ratio according to the final application (light bundling, heavy-duty packaging), achieving flexible production from standard to ultra-high strength strapping.

Key Features
  • Wide draw ratio: 1.5-12 continuously adjustable for different strength needs
  • High hardness rollers: HRC60, wear-resistant and uniform heat transfer
  • Precise temperature control: 6KW mold temp controller ensures stable roller surface temperature
  • Adequate insulation: 100mm reduces energy consumption and stabilizes thermal field
  • Pressure extension: Additional roller provides auxiliary stretching force for higher orientation
  • High strength output: High draw ratio significantly increases longitudinal strength
  • Flexible switching: Different draw ratios for different product grades
  • Wide temperature range: 50-250°C covers PP and modified material processing
  • Long heating zone: Total 6.5m ensures sufficient preheating and stretching
  • Energy-saving design: Thick insulation reduces heat loss
Technical Questions & Answers
Is a higher draw ratio always better? How to choose the optimal value?
Not necessarily. Higher draw ratio increases strength and stiffness but reduces elongation at break (making it more brittle). The choice requires balance: high draw ratios (8-12x) for heavy-duty packaging, moderate draw ratios (4-7x) for applications needing flexibility. We provide performance data at different draw ratios for reference.
Why does the extension box need a mold temperature controller?
The rollers inside the extension box need precise temperature control to keep the PP tape in the proper rubbery state during stretching. The mold temperature controller circulates hot oil or water to provide stable, uniform roller surface temperature, avoiding localized overheating or cooling that could cause uneven stretching or tape breakage.
What is the purpose of the 100mm insulation?
It significantly reduces heat loss, lowering energy consumption. It also keeps the internal temperature more stable, reducing frequent on/off cycling of the temperature control system and extending the life of heating elements.
