Product Description
Biaxial Brilliance: High-Strength PET Strapping Line
Advanced Biaxial Stretching Technology
Our high-strength PET strapping production line utilizes advanced biaxial stretching technology to achieve exceptional material performance. Through precise molecular orientation in both machine direction (MD) and transverse direction (TD), we transform PET material into high-performance strapping with tensile strength exceeding 600 MPa, excellent flexibility, and minimal rebound.
Core Process Features
- Sequential Biaxial Stretching: MD stretching followed by TD stretching for optimal molecular alignment and crystallinity
- Machine Direction System: Multi-roller preheating with precise ratio stretching above glass transition temperature
- Transverse Direction System: Rail-type tenter frame with adjustable width and heat-setting zone
- Synchronization Control: Speed interlock between MD and TD systems ensures smooth tension transition
- Process Flexibility: Independent adjustment of MD and TD draw ratios for customized product specifications

Frequently Asked Questions
How to choose the biaxial draw ratios? What is their impact on the final product?
Draw ratio is the key process parameter determining product strength. Higher draw ratios result in greater molecular orientation and increased longitudinal tensile strength, though transverse strength may be relatively lower. Products become thinner and stiffer with higher ratios. Our production line offers wide adjustability and includes process guidance to help optimize parameters based on your specific thickness, width, and performance requirements.
Breakage or uneven thickness often occurs during stretching. How is this resolved?
Breakage typically relates to material quality issues (moisture, impurities), uneven preheating, or improper draw ratio settings. Our system prevents these issues through proper material drying, uniform temperature control, and smooth tension transition. Uneven thickness primarily stems from initial extruded sheet inconsistencies, which our integrated system addresses through precise extrusion and die control from source to final process.
