Anti-Fog PP Container for Cold Display
Why fog forms and why it matters
Cold food plus a cold lid equals condensation. On untreated PP, water forms discrete droplets that scatter light — the customer sees a fogged lid and cannot judge the food. Anti-fog makes water spread into a thin continuous film instead, which stays transparent.
In a supermarket chilled cabinet, this is the difference between a product that sells and one that looks stale.
Options
| Method | Effect duration | Cost impact | Applies to |
|---|---|---|---|
| Anti-fog masterbatch in resin | 12–24 months | +8–12% | lid or whole container |
| Surface coating | 6–12 months | +10–15% | lid only |
| Anti-fog PET film lid | 24 months+ | +15–20% | lid only |
The test that matters
Ask for a fog test at 4°C for 48 hours with the actual food. Suppliers who claim anti-fog without a test are usually relying on a masterbatch that fades after a few months in a warehouse.
Simple field test: put the container in a fridge with a warm, moist item inside and photograph at 2, 12 and 48 hours.
FAQ
Does anti-fog affect food safety? No, approved additives are food-contact compliant. Ask for the migration test.
Does it work in freezers? Freezer fog is different; specify freezer-grade anti-fog separately.
