Hydrophobic Yoghurt Lidding Film: Zero-Residue Packaging Revolution
Super Hydrophobic High Efficiency Yogurt lidding Film - Zero Adhesion, Easy Tear, 100% Seal for Freshness
The Science Behind Sticky-Free Dairy Packaging
Traditional foil/plastic lids fail because:
➔ Low Contact Angle (<90°) allows yogurt adhesion via capillary forces
➔ High Peel Force (20-30N) demands disruptive tearing motions
Hydrophobic Yoghurt Lidding Film solves this through nano-engineered surfaces modeled after lotus leaves. This article reveals how its triple-layer design achieves <10% residue rates while meeting strict food safety standards.
4 Breakthrough Features of Hydrophobic Yoghurt Lidding Film
1. Molecular Armor: Lotus-Inspired Surface
✓ Material: Fluorinated ethylene propylene (FEP) or PDMS coatings
✓ Contact Angle: 170°-175° (superhydrophobic range)
✓ Performance:
Residual yogurt ≤1.2g per 150g cup (ISO 22653:2021)Static friction coefficient <0.15 (vs 0.35 for standard lids)
2. Precision-Engineered Peelability
✓ TLaminate Structure: PET/AL/PE·EVA/FEP (document-QFD optimized)
✓ Peel Force Control:
