MANUFACTURE OF AGRICULTURAL SYNTHETIC RESIN COATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an agricultural synthetic resin coating material for maintaining a high transparency for a long period. SOLUTION: The method for manufacturing an agricultural synthetic resin coating material having a dustproof resin film having a thickness of 0.5 to 5μm and formed at least on one side surface of a soft polyvinyl chloride film having a thickness of 30 to 500μm comprises the steps of forming a rolled material of the coating material, and then continuously heat treating the rolled material at 40 to 70 deg.C for a time of 20 to 100 hours.
