AGRICULTURAL SYNTHETIC RESIN LAMINATED JOINED FILM

摘要

PURPOSE:To provide an agricultural synthetic resin laminated junction film spreadable for a long period in which at least two soft synthetic resin laminated films having a plurality of fibrous or rectangular reinforcing members interposed between two soft synthetic resin films are connected by a satisfactorily bonding strength without lateral burn scorching and burn-off. CONSTITUTION:An agricultural synthetic resin laminated junction film is obtained by connecting a soft synthetic resin laminated film obtained by laminating a plurality of fibrous or rectangular reinforcing members between two soft synthetic resin films at least in a lateral direction by a high frequency sewing machine having roll-like electrodes of an upper rotor having a width of 15-30mm and a diameter of 60-150mm and a lower rotor having a width of 17-45mm and a diameter of 90-150mm.
