Abstract:
PROBLEM TO BE SOLVED: To provide a technology requiring only one film to be inserted between so-called tack materials to reduce the cost of the material (film), facilitate the management of the material (film), reduce the production cost of the final product (laminate of the tack material and the film), decrease the number of waste films and improve the releasing (take-out) workability of finely cut tack material. SOLUTION: The film to be inserted between laminating adhesive sheets has recesses on the upper surface of the film, i.e. the surface opposite to the adhesive sheet positioned above and protrusions on the lower surface of the film opposite to the adhesive sheet positioned below.
