english How Cotton Baling Film Balances Strength and Flexibility
2025-06-11
Material Composition
- Primary materials: HDPE or LLDPE
- Additives: calcium carbonate or talc for enhanced tensile strength
- Thickness range: 15-30 microns optimized for compression resistance
- Elongation at break: ≥300% to prevent brittleness
Flexibility Mechanisms
- LLDPE's branched molecular chain enables superior elasticity
- Blown film extrusion creates balanced molecular orientation
- Controlled addition of plasticizers or elastomeric modifiers
- Maintains ductility without compromising tensile strength
Manufacturing Process
- Polymer chain alignment through stretching during extrusion
- Rigorous quality control for uniform thickness
- Consistent additive distribution prevents weak spots
- Precision balance between rigidity and flexibility
