This production line produces PP strapping with excellent dimensional stability - no deformation and no edge curling during long-term storage and use. This is achieved through the combination of multi-stage stretching and heat setting: first, 1.5-12x adjustable stretching for molecular orientation, followed by a 4.0-meter far-infrared oven (50-200°C adjustable, ±2°C control accuracy) for thorough heat setting to eliminate orientation-induced internal stress. Then, dual cooling tanks (3.5m+5.5m, water temperature 10-25°C adjustable) provide uniform cooling to further fix dimensions. The finished strapping remains straight and flat during storage, transport, and long-term use - no deformation, no warping.

Key Features & Benefits
Deformation-free guarantee: Excellent dimensional stability - no curling or warping
Low thermal shrinkage: Thorough setting results in extremely low shrinkage - no deformation at high temperatures
No edge curling: Uniform molecular orientation and stress elimination keep edges flat
Storage stability: Remains straight after long-term storage - ready to use anytime
Transport safety: No deformation means no damage from挤压 during transport
Customer satisfaction: End users don't waste time dealing with deformed straps
Premium quality: Dimensional stability is a key indicator of high-quality strapping
Technical Q&A
Q: Why do straps deform?
A: Deformation results from internal stress generated during molecular orientation in stretching. If internal stress is not fully eliminated, the strap gradually releases stress during storage or use, causing curling, warping or twisting.
Q: How does heat setting eliminate internal stress?
A: The strap passes through a 4.0m far-infrared oven (50-200°C adjustable) under tension. Molecular chain segments gain enough energy to relax and re-crystallize, releasing orientation-induced internal stress. Uniform cooling then fixes the new structure - the strap no longer deforms.
Q: What value does deformation-free bring to end users?
A: Deformed straps jam in automatic strapping machines and add difficulty in manual strapping. Deformation-free straps stay straight and flat - they work smoothly whenever used, reducing waste and customer complaints.
