More Information
Summary:This invention provides a laminated thermoplastic resin film having excellent adhesion and antiblocking properties. The laminated thermoplastic resin film comprises a thermoplastic resin film and a covering layer provided on one side or both sides of the thermoplastic resin film and comprising an interpolyester resin and a polyurethane resin. The structure of the covering layer is that microphase separated or nano phase separated structure is observed in PEs phase A composed mainly of a copolyPEs resin and PU phase B composed mainly of a PU resin. The area ratio of PEs phase A (dark color phase in phase image) on the covering layer surface (PEs surface fraction) defined by formula (1) is not less than 35% and less than 90% in a measurement area of 5 m 5 m as observed in a phase measurement mode under a scanning probe microscope. PEs surface fraction (%) = (area of PEs phase A/measuring area) x 100 (1).
