Super Straight P.P. Strap Production Line

This production line manufactures PP strapping with exceptional straightness, maintaining deviation within 15mm/m - making it the ideal consumable for fully automatic strapping machines. Through a multi-stage stretching process (adjustable from 1.5-12x), molecular chains achieve high orientation, followed by a 4.0-meter far-infrared sizing oven (±2°C temperature control accuracy, 100mm insulation) that completely eliminates internal stress to prevent curling or warping. Multiple three-roller haul-off units with ±1 m/min speed accuracy ensure consistent tension throughout the production line. Dual cooling tanks (3.5m+5.5m, water temperature 10-25°C adjustable) guarantee uniform cooling and setting. The finished strapping feeds smoothly without jamming in fully automatic strapping machines, making it highly preferred by premium packaging companies.

• Ultra-high straightness: Deviation ≤15mm/m, far exceeding industry standards
• Precision heat setting: 4.0m far-infrared oven fully eliminates orientation-induced internal stress
• Uniform cooling: Dual cooling tanks (3.5m+5.5m) ensure uniform crystallization, no edge curling
• Precise speed matching: Multiple haul-off units with ±1 m/min accuracy eliminate tension-induced camber
• Preferred for automatic machines: Straight straps feed smoothly, never jam
• No curling or deformation: Internal stress eliminated, straps stay flat with no raised edges
• Reduced equipment wear: Low camber reduces friction on strapping machine guide channels
• Improved efficiency: Smooth feeding reduces downtime, continuous line operation
• Export quality: Straightness meets demanding requirements of Europe, US, Japan
• Zero jamming complaints: End users never complain about bent straps
