PROBLEM TO BE SOLVED: To provide a paper product-containing carton capable of properly setting easiness-to-cut of an opening perforation for taking out a laminate, even if basis weight and a paper thickness of a carton are low.SOLUTION: In a paper rectangular solid-shaped carton 20 for storing a laminate of a paper product 25, basis weight of the carton is 250-370 g/m, and a plate thickness (t) is 0.28-0.43 mm/sheet, and an opening perforation 210 is formed for forming a takeout port on a top surface 201 of the carton, and the opening perforation comprises two long side parts 210L1 and 210L2 and two short side parts 210W respectively connected to both end of the two long side parts, and 50% or more of the length of the long side parts is composed of double or more of perforations, and on the perforation being the longest in a cutting line among the short side parts, in a part of 50% or more of the length of the short side parts, the length of a cutting line n1 is 7-35 mm, and the length of a connection part c1 between the adjacent cutting lines n1 is 0.70-1.40 mm, and is also (the length (mm) of the connection part c1)/(a paper thickness (mm))=t2.0-4.0.SELECTED DRAWING: Figure 4 |
