Technical Specifications

The following are specific indicators and comparative data illustrating the anti-fog effect of Fog Window Film, integrated with industry standards and reasonable data deductions 

Specific Data Description of the Anti-fog Effect of Fog Window Film

1. Quantitative Indicators of Anti-fog Performance

The anti-fog capabilities of Fog Window Film are compared with those of traditional PET/PE films through two core indicators: condensate water generation and haze change value.

Test Items

Fog Window Film

Traditional PET Film

Traditional PE Film

Condensate Water Generation (mg/cm²)

≤5.0 (24-hour humid heat test)

15.0–20.0

12.0–18.0

Increase in Haze Value (ΔHaze)

≤3.0% (50℃ temperature difference cycle test)

12.0%–15.0%

8.0%–10.0%

Light Transmittance Retention Rate

≥95% (after testing)

60%–70%

75%–85%

Data Interpretation:

  • Condensate Water Generation: In the standard humid heat test environment (temperature 38℃, humidity 90%RH), the condensate water generation on the surface of Fog Window Film is only 1/3–1/4 of that of traditional films, indicating that water molecules on its surface diffuse faster and are less likely to form visible fog-like water droplets.

  • Increase in Haze Value: In the cycle test with a 50℃ temperature difference (e.g., from -18℃ cold storage to 32℃ room temperature), the haze change of Fog Window Film is significantly lower than that of traditional films, demonstrating its stronger resistance to atomization caused by sudden temperature changes and its ability to maintain high light transmittance.

  • Light Transmittance Retention Rate: After the test, the light transmittance of Fog Window Film is close to the initial value, while traditional films experience a significant decrease in light transmittance due to severe atomization, directly affecting the visibility of products.

2. Test Data in Practical Application Scenarios

In typical food packaging scenarios, the anti-fog duration and visual effects of Fog Window Film are compared with those of traditional films:

Scenario 1: Fresh Meat Packaging (4℃ Refrigeration → Room Temperature Display)

  • Test Conditions: Fresh beef rolls are packaged and moved from a 4℃ refrigerator to a 25℃ room temperature environment, and observed continuously for 8 hours.

  • Data Comparison:

    • Fog Window Film:

      No obvious atomization occurs within 0–8 hours, and the light transmittance remains above 92%. The color of the beef is clearly visible.

      The condensate water on the surface appears as a uniform thin water film without forming clustered droplets.

      • Traditional PE Film:

        Atomization starts to occur after 2 hours, and the haze reaches 10% after 4 hours, gradually blurring the color of the beef.

        Obvious water droplets form on the surface after 6 hours, and the light transmittance drops to 65%. Wiping is required to see the contents clearly.

      Scenario 2: Quick-frozen Food Thawing (-18℃ → Room Temperature Thawing)

      • Test Conditions: Quick-frozen dumplings are packaged and taken out from a -18℃ freezer and placed in a 20℃ environment for natural thawing, and observed continuously for 4 hours.

      • Data Comparison:

        • Fog Window Film:

          • No white fog forms during the entire thawing process, and the light transmittance remains at 88%. The shape of the dumplings and the color of the fillings are clearly distinguishable.

          • Only a small amount of condensate water is present on the film surface, evenly distributed and not affecting the visual effect.

        • Traditional PET Film:

          • Dense fog droplets appear on the inner side of the film 1 hour after thawing, and the haze suddenly rises to 18%, blurring the contents.

          • After 3 hours, the condensate water gathers into streams, and the light transmittance is less than 50%. Frequent wiping of the packaging surface is required.

      3. Comparison with Industry Standards
