PROTECTIVE FILM FORMING FILM, COMPOSITE SHEET FOR FORMING PROTECTIVE FILM, AND TRANSPORTATION METHOD OF WORK HAVING PROTECTIVE FILM FORMING FILM

摘要

A test piece having a width of 4 mm and a thickness of 200 ± 20 µm is produced by laminating a plurality of sheets of the protective film forming film of the present embodiment, and the test piece is held under the measurement conditions of a tensile mode with a frequency of 11 Hz and a temperature increase rate of 3° C./min. When the storage elastic modulus of the test piece is measured, the storage elastic modulus when the temperature of the test piece is 70° C. is E' 70 , and the maximum value of the reflectance of light having a wavelength of 380 to 780 nm of the protective film forming film is R max . , the Y value calculated by the formula: Y=(log 10 E' 70 ) 2 ×R max is 260 or more, and the X value calculated by the formula: X=(log 10 E' 70 ) 2 is 33 or more.
