    摘要： A surface protective film that exhibits superior adhesiveness to an adherend and exhibits only small differences in peel strength according to the surface state of an adherend is provided. The surface protective film 10 is provided with an acrylic pressure-sensitive adhesive (PSA) layer 2 on one side of a support 1, and satisfies the following conditions: a thickness reduction ratio (indentation strain E1) when a compressive stress of 0.195 MPa is applied for 10 minutes to a laminate 20 obtained by laminating 24 of the protective films 10 is 7.0% or more, and a ratio (E1/E2) of E1 to a thickness reduction ratio (permanent strain) E2 that remains 10 minutes after the stress is released is 30 or less; and a peel strength S1 on a plain TAC polarizing plate is two times or less a peel strength S2 on a TAG polarizing plate that has been subjected to AG treatment.

    摘要： Disclosed is a polylactic acid-based film or sheet as a resin film or sheet including a polylactic acid (A). The film or sheet has a melt endotherm ΔHc′ of 10 J/g or more, where ΔHc′ is of a region crystallized upon film formation and specified by following Expression (1): ΔHc′=ΔHm−ΔHc  (1) wherein ΔHc represents an exotherm (J/g) associated with crystallization of the film or sheet in a temperature rise process after film formation; and ΔHm represents an endotherm (J/g) associated with subsequent melting of the film or sheet, each determined by DSC. The film or sheet has a tear strength of 2.5 N/mm or more both in a machine direction (MD) and a transverse direction (TD). The polylactic acid-based resin film or sheet is resistant to melting and deformation even at an elevated temperature higher than 100° C. and is resistant to breaking and tearing during winding into a roll.
