れる。A stretch film for wrapping grass is required to maintain high airtightness outdoors for a long period of time, and therefore has a toughness (breaking strength in the longitudinal direction of 280 kg / cm 2 or more) which is not broken by the unevenness of the grass surface. ), Sufficient stretchability (breaking elongation in the longitudinal direction of 500% or more), and strong binding force (tensile stress required to stretch the film to twice the length in the longitudinal direction).
(more than kg / cm 2 ), elasticity (tensile stress after stretching for 5 minutes after stretching in the longitudinal direction to twice the length, ie elongation recovery force of 80 kg / cm 2 or more, elongation recovery rate of 60% or more), self Adhesiveness (30g / 200mm
Width or more), UV blocking property, and no unevenness of elongation are required.
