Provided is a surface protection sheet that is less susceptible to breaking and tearing caused by adherend processing and can be easily removed from the adherend. The surface protection sheet comprises a substrate and a PSA layer placed on one face of the substrate. The base polymer of the PSA layer has a glass transition temperature of &#x2212;50&#xb0; C. or higher. The surface protection sheet has at least 200% elongation at break in both the machine direction and the transverse direction.

Surface protection sheet

A pressure-sensitive adhesive tape that uses, as a plasticizer, an alternative compound to bis(2-ethylhexyl) phthalate (DOP) and dibutyl phthalate (DBP), having excellent tackiness, and can be unwound satisfactorily, where DOP and DBP are to be restricted under the REACH regulation. The pressure-sensitive adhesive tape includes a poly(vinyl chloride) substrate and a pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer is disposed on or over one side of the substrate. The poly(vinyl chloride) substrate contains 10 to 40 percent by weight of bis(2-ethylhexyl) terephthalate. The pressure-sensitive adhesive tape preferably has an unwinding force of 0.4 N/20 mm or less at a tensile speed of 0.3 m/min and an unwinding force of 1.2 N/20 mm or less at a tensile speed of 30 m/min.
