The pressure-sensitive adhesive film or sheet, a surface protective film or sheet, and its application in the protection of the surface of the article

Adhesive film or sheet of the invention has an ethylene - an adhesive layer (meth) acrylate copolymer (A) is. The ethylene - random binary copolymer (meth) acrylate copolymer (A) of ethylene and (meth) acrylic acid alkyl ester, the (meth) acrylic acid alkyl ester the alkyl carbon atoms the number is 2 or more, the ethylene - (meth) acrylate copolymer (a) based on the measurement of the melting point T JIS K7121-1987 [deg.] C] and (meth) acrylic acid alkyl ester unit content of the above-described X [mol %] satisfy the following formula (1). -3.0X + 125≥T≥-3.0X + 107 (1) (wherein, the adhesive layer does not contain a melting point of 115 deg.] C is a highly crystalline ethylene or propylene polymer or copolymer).
