<p>The present invention is to provide a plastic film with an improved air permeability and a usage thereof, which enable to harvest fresh fruits by forming penetration holes and attaching a sunlight shielding net thereto so that the hot air is discharged to the upper side of the plastic film through the penetration holes by using the characteristic of hot air, and humidity or moisture is transferred to down. Specifically, the present invention is to provide a plastic film and a usage thereof, in which a sunlight shielding film is partitioned and attached to the penetration holes along the direction that the penetration holes are formed, i.e., the longitudinal direction of the plastic film, so that the air permeability is improved while the enough sunlight is transmitted into the plastic film. The plastic film with an improved air permeability according to the present invention including a plastic film manufactured continuously in the longitudinal direction with a predetermined width, and is characterized in that at least two rows, which consist of multiple penetration holes formed in the central area of the width at predetermined intervals throughout the entire length of the plastic film, are formed, and that the sunlight shielding net is attached to cover the rows on one side of the plastic film in the longitudinal direction.</p> |
