WRAPPING FILMS

摘要

A wrapping film has a sticky surface on at least one of its sides. A shear adhesion strength as measured subsequent to bringing the sticky surface into contact under a pressure of 4 Pa with a glass surface having a surface roughness of from 0.7 to 1.5 nm is at most 400 cN/25 cm<2>, and a shear adhesion strength as measured subsequent to bringing the sticky surface into contact under a pressure of 4 kPa with the glass surface is at least 700 cN/25 cm<2>. Another wrapping film has on a surface thereof convexities sufficient to provide the surface with a roughness and waviness (Ra') of at least 40 nm as measured in a non-extended state, and has an elongation at break of at least 10 %.
