With anti-drip films the droplets that form on the inside of the greenhouse's film due to condensation are eliminated. This is achieved with the addition of special additives that increases the surface temperature between the film and droplets. A continuous thin layer of water is formed that runs of to the side without dripping on the plants. By decreasing the droplets on the inside of the film the light transmission increases and the spread of disease by means of droplets decreases.
UV Blocking Films(AV)
Films which absorb UV radiation up to 375 nm. These films control the spread of certain diseases be reducing the sporulation of the relevant fungi. This reduces the movements of aphips thrips and other insects in the greenhouse .Furthermore, this additive also reduces the blackening of rose petals.
Films that incorporate selected additives and pigments to modify the light spectrum entering the greenhouse and then changing the growth behaviour of plants.
