Key Features:
- Pre-Scored Chambers: Easy-to-tear compartments for single servings.
- Anti-Fog Coating: Optional inner layer to maintain product visibility.
- High Seal Strength: ≥ 10 N/15mm to prevent leaks.
Material Structure:
- 7-Layer Film: PET/AL (Aluminum Foil)/NY/PE/EVOH/Adhesive/PP.
- Thickness: 120–250 microns.
Benefits:
- Reduces food waste by enabling controlled portioning.
- Compatible with vertical and horizontal form-fill-seal (VFFS/HFFS) machines.
