| Comparison Dimension | Cast Polyethylene Film | Blown PE Film |
|---|---|---|
| Thickness Uniformity | Advantage: Small thickness deviation (±5%) due to precise T-die extrusion control | Disadvantage: Larger thickness deviation (±8-10%) affected by blowing process |
| Transparency & Flatness | Advantage: High transparency (90%+) and smooth surface without wrinkles | Disadvantage: Lower transparency with uneven, wrinkled surface |
| Internal Stress | Advantage: Low internal stress with good dimensional stability | Disadvantage: High internal stress causing warping and deformation |
| Heat-Sealing Performance | Advantage: Excellent heat-sealing with stable strength and wide temperature range | Disadvantage: Poor heat-sealing with unstable strength and narrow range |
| Post-Processing Adaptability | Advantage: Good adaptability for corona treatment, printing and lamination | Disadvantage: Relatively poor post-processing adaptability |
| Production Efficiency | Advantage: High line speed (50-150m/min) with online edge material recycling | Disadvantage: Lower line speed (20-50m/min) with higher material loss |
