Abstract:
There is provided an interlayer film for laminated glass with which the production efficiency of laminated glass can be heightened. The interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a one-layer structure or a two or more-layer structure and includes a first layer containing a thermoplastic resin, the softening point of the first layer is 60° C. or more, the interlayer film has an MD direction and a TD direction, and with regard to thermal shrinkage ratios obtained when the first inside portion, the second inside portion and the central portion are heated for 2 minutes at 80° C. respectively, all of the thermal shrinkage ratio MD1MAX, the thermal shrinkage ratio MD2MAX and the thermal shrinkage ratio MD3MAX are 18% or less.
