polystyrene BOPS rigid film for food packaging material
2026-01-07 15:52BOPS Rigid Film is a premium choice for high-clarity, rigid thermoformed packaging across food, pharma, and consumer goods sectors. Its combination of strength, transparency, and processability makes it a preferred alternative to PET and standard PS films—especially where visual appeal and structural performance are critical.
Best Practices for Thermoforming with BOPS:
1. Use pre-heating temperatures between 150–190°C (adjust based on film thickness).
2. Maintain uniform heating to prevent uneven shrinkage.
3. Optimize mold design with adequate draft angles (>2°) to reduce stress.
4. Use cooling air at controlled pressure and temperature to avoid warping.
5. Avoid contact with sharp edges or high-friction surfaces during handling.
