PURPOSE:To prevent generation of sweating by making use of a film molded of synthetic resin to which an appropriate quantity of cyclodextrin has been added. CONSTITUTION:Cyclodextrin performs an action where saturated vapor in air is absorbed by the interposition thereof among molecules of synthetic resin of the main raw materials of a film. Saturated vapor in air within a vinyl house is grasped as condensed water by condensing the saturated vapor through what is called a clathrate (moisture absorption) action of the cyclodextrin. Consequently, a water drop does not fall onto leaves of a plant during its cultivation within the vinyl house, and not only damage of the leaves of the plant but also an obstruction of growth can be prevented.
