Film for use as thermosensitive stencil printing cardboard sheet

A film for a thermosensitive stencil printing base sheet, comprising a biaxially stretched film of a thermopplastic in having thickness of 0.2 to 7 micrometers, said film showing at least two fusiion peaks in its DSC temperature elevation measuring chart (the rate of temperature elevation 20 °C/min.), at least two fusion peaks having the following relation: Tmp (max) ≦260 (°C) Tmp (min) ≧ 90 (°C) Tmp ≧ 10 (°C) 5(cal/g) ≦ ΔHu (total) ≦ 13 (cal/g) 0.05 ≦ ΔHu(min)/ΔHu (total ≦ 0.9 wherein Tmp (max) is the temperature (°C) of the fusion temperature on the highest temperature side, Tmp (min) is the temperature (°C) of fusion peak on the lowest temperature side, ΔTmp is Tmp (max) - Tmp (min), ΔHu(total) is the total fusion energy (cal/g), and ΔHu(min) is the fusion energy (cal/g) of the fusion peak on the lowest temperature side.
