Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a laminate sheet for package cushioning material capable of surely fixing a product to a frame base paper body when packaging for transportation of the product and capable of coating without exposing article itself from an outside.SOLUTION: There is provided a laminate sheet for package cushioning material by laminating a heat shrinkage film satisfying following requirements (1) to (3) and a non-shrinkage film having all light transmittance of 50% or less and forming adhesive parts on 2 or more locations separately on a laminate layer. (1) Shrinkage factor in a film main shrinkage direction when shrinking it in warm water of 90°C for 10 sec. is 30% to 60%. (2) Shrinkage factor in an orthogonal direction to the film main shrinkage direction when shrinking it in warm water of 90°C for 10 sec. is 30% or less. (3) difference of shrinkage factor in the film main shrinkage direction and the orthogonal direction to the film main shrinkage direction when shrinking it in warm water of 90°C for 10 sec. is 20% or more.SELECTED DRAWING: Figure 1
