[Problems to be solved by the invention]
In the toilet paper packaging bag 20 described above, since the perforations 34 of the gripping portion 22 are formed in the vertical direction of the gripping portion, the strength of the gripping portion is less reduced, and the packaging bag is less likely to be broken when being carried. It has advantages. However, when the bag 20 is opened and the roll product is taken out, the bag is opened by the perforation 34 of the grip portion 22, but the bag is torn from the grip portion 22 to the main body portion 24 because of the vertical perforation 34. It has the disadvantage that roll products that are not used because they have been torn or are torn too much are exposed, and the tears are not clean. It is conceivable to provide perforations on the main body to solve such defects, but in this case, the perforations on the main body weaken the strength of the main body and endure the load of multiple roll products. It is conceivable that the strength is not high enough to be obtained, and for example, inconveniences such as breakage of the bag during transportation are generated.
