Stops condensation forming droplets on greenhouse and tunnel film, so more light reaches the crop and water does not drip onto plants.
Inside a greenhouse, warm humid air meets the cooler film and condenses. On untreated polyethylene the water forms small droplets. Those droplets scatter and reflect sunlight, cutting the light that reaches the crop, and when they fall they wet leaves and fruit, encouraging disease.
An anti-fog additive lowers the surface tension at the film surface, so condensation spreads into a thin, transparent layer that runs off instead of forming droplets. The film stays clear and the water runs down the side rather than dripping onto plants.
Anti-fog additives work by migrating to the film surface, so the result depends on the resin, film thickness, layer structure and other additives in the film, especially UV stabilisers. That is why we recommend a dose for your film structure and test the grade in both hot fog and cold fog conditions before you change your specification.
Prevents condensation droplets on agricultural and food film.
PE / LLDPE · Agricultural and food film
Long-life UV protection, with agrochemical-resistant options.
PE / LLDPE · Greenhouse, mulch and agricultural film
UV and thermal protection in one dose.
PE / PP · Outdoor products and long-life film
Retains night-time heat in greenhouses.
PE / LLDPE · Greenhouse and thermal-control film
In co-extruded film, anti-fog goes in the inner layer facing the crop, where condensation forms.
Anti-fog and UV stabilisers must be compatible, so specify them together for the film's target life.
Test at the temperatures the film will see: warm days and cold nights behave differently.
Match anti-fog durability to the film's planned life so it does not run out before the UV protection.
They describe the same effect. The anti-fog additive makes condensation spread into a continuous water film instead of droplets, which stops fogging and stops water dripping onto the crop.
Yes, and greenhouse film almost always needs both. The two additives have to be compatible, so we recommend AFG together with AGR or UVX and confirm the combination in testing.
It depends on film thickness, layer structure and growing conditions. We set the dose to match the film's planned service life and agree the test method with you.
Send us your polymer, process and the problem you want to solve. We recommend a grade and starting let-down, then ship a 1 kg lab sample, 5 kg pilot sample or 25 kg line trial with TDS, SDS and batch COA.
Masterbatch has to prove itself on your extruder, not ours. This is the route every new grade takes.
Polymer, process, the problem to solve, and your current product if you have one.
A grade and a starting let-down for your line, shared with you shortly.
A 1 kg lab sample, 5 kg pilot sample or 25 kg line trial, with TDS, SDS and batch COA.
We review the results with your team and adjust dosage or formulation.
Price, MOQ and lead time fixed against the approved grade.
