Roll material

Abstract

To ensure quality of a roll material.SOLUTION: A packaging roll material is obtained by winding a piece of belt-like paper material 12, and partially laminating a seal material in advance onto the paper material 12. The packaging roll material comprises: a first additional part 14a, which is provided on the paper material 12 continuously in a roll peripheral direction D1 along one end edge S1 in a roll axial direction D2, and in which a one-end seal material being at least part of the seal material, is laminated in advance in a thickness direction with respect to the paper material 12, so as to add a thickness in a roll diameter direction of the paper material 12; and a second additional part 15a, which is provided on the paper material 12 continuously in the roll peripheral direction D1 along the other end edge S2 in the roll axial direction D2, in which a laminate material is laminated in advance in the thickness direction with respect to the paper material 12, so as to add a thickness in the roll diameter direction of the paper material 12.SELECTED DRAWING: Figure 1
