。In order to solve this problem, efforts have been made to improve cohesion, which is considered to have the greatest influence conventionally. As a method for this purpose, the glass transition point of the copolymer constituting the adhesive is increased, the crosslinking density is increased, and the molecular weight is increased. However, even if such cohesive force improvement measures are implemented, the sealability of corrugated cardboard does not improve as much as expected, and when cohesive force is improved, adhesion force decreases.
