1.Expanded Anti-Mist Film Product Detail Outline for Fresh Meat & Food Packaging
Product Overview & Technology
2.1 Core Technology
Huasu Anti-Mist Film utilizes a multi-layer co-extrusion process with hydrophilic anti-fog coatings on both sides, forming a micro-porous network that disperses condensation into a transparent thin film instead of fog droplets. This technology addresses the primary challenge of mist formation caused by:
• Temperature fluctuations during transportation (-18°C to +40°C)
• Moisture release from fresh products
• Condensation during display in refrigerated cases
2.2 Value Proposition
• 300% clearer visibility compared to standard PE films (ASTM D1003 light transmittance test)
• 50% reduction in product returns due to improved visual inspection of packaged goods
• Extended shelf life by maintaining optimal packaging atmosphere (when used with MAP systems)
