SCATTERING-PREVENTIVE AND ENERGY-SAVING FILM

PROBLEM TO BE SOLVED: To improve the tear strength of a base material by adopting a laminat ed sheet consisting of two of more layers of resin film stretched in the uniaxial direction in a manner that the layers of the resin film are crossed with each other in an almost orthogonal direction in their stretch direction, as a base material, on one of the faces of which a pressure-sensitive tackifier layer is provided. SOLUTION: A film 1 is, manufactured by strongly stretching a resin for example in the lengthwise direction, and another film 2 is manufactured likewise by strongly stretching the resin in the crosswise direction, further the resin film 1 and the resin film 2 are laminated together through an adhesive layer 3 applied between the films 1, 2, for example by stacking at least two or more layers of the films 1, 2 alternately so that their lengthwise and crosswise stretch directions are almost orthogonally crossed to each other. This laminated sheet 4 thus obtained is provided with a pressure-sensitive tackifier layer 5 formed on either one face of the resin films 1 or 2.
