SureSeal™ Technology

The foundation of Cultiva’s cuticle care product platform is SureSeal™ technology, developed at Oregon State University. Starting with an advanced scientific understanding of the fruit’s natural cuticle layer and its protective qualities, researchers developed a hydrophobic, elastic biofilm that not only protects the cuticle – it also supplements and enhances it. Cultiva furthered the discovery and development work originated by researchers at the University to bring a commercial formulation to market.

SureSeal delivers both a physical and biochemical mode of action, to enhance the cuticular membrane stability and increase the plant’s tolerance to environmental stress. The biofilm supplements plants’ cuticular membrane from within, by increasing the efficiency of photosynthesis and the amount of protective antioxidants. Externally, the biofilm provides a protective elastic coating that fills in microcracks, expands as the fruit grows, and reduces water loss, while still allowing exchange of gases from within the leaves and fruit.
