Abstract
PURPOSE: To provide an agricultural mulch film covering material which has high tearing strength and impact strength, exhibits well-balanced strength in a vertical direction and in a horizontal direction and is little damaged by heat fusion, by molding a mixt. of high-density PE and a specified amount of an olefin rubber into a film.
CONSTITUTION: 70W98pts.wt. high-density PE (A) having a density of 0.94W 0.97g/cm2 and a melt index of 0.01W1.0g/10min (190°C) is blended with 30W 2pts.wt. olefin rubber (B) compatible with the composition (A) [e.g. an ethylene- propylene (or 1-butene) random copolymer having an ethylene content of 60W 95mol%). The resulting compsn. is extruded into a film by T-die, etc. to obtain the titled covering material having a thickness of 5W15μ.
EFFECT: The material has excellent adhesion to soil.
USE: Films, useful for open culture, culture in plastic tunnel, semiforcing culture in plastic greenhouse, etc.
