A heat shrinkable film is laminated on a film having less heat shrinkage which can be a metal coated film with an adhesive composition having a relatively low shear strength. The heat shrinkable laminate film forms creases by heat shrinking it.
Claims20
A heat shrinkable laminate film which comprises a heat shrinkable synthetic resin film and a low shrink film which forms creases or crepes when said laminate is heat shrunk, and which is lamimated on the heat shrinkable film with an adhesive composition having low cohesive force and high melt flowability and an adhesive strength lower than the shrinking force of the heat shrinkable film.
