Abstract
An easily peelable laminated film includes a laminate of a peelable surface layer (B) having a peeling strength of 5 to 100 g/cm with a base layer (A) containing a thermoplastic resin. The laminated film of the invention provides an easily peelable laminated film excellent in water resistance as a base material for, for example, concealing seals and labels for preventing re-pasting. The easily peelable laminated film of the invention requires no specific process to start peeling.

A peelable laminated label (ii) comprising:
- a peelable laminated film (i) having an opaqueness of from 60 to 100%, which comprises a laminate of a peelable surface layer (B) having a thickness of from 1 to 7 μm, a peeling strength of from 5 to 150 g/cm and containing from 10 to 80 wt % of an inorganic fine powder and/or an organic fine powder and from 90 to 20 wt % of a thermoplastic resin, and a base layer (A) comprising a thermoplastic resin;
- and
- a pressure-sensitive adhesive directly provided on the surface of the peelable surface layer (B);
- wherein
- both of the tensile strength and the tear strength of base layer (A) are respectively stronger than the tensile strength and the tear strength of peelable surface layer (B).
