Paper towel roll

Abstract

The present invention provides a kitchen towel roll made by winding a bulky, embossed kitchen towel sheet into a roll, which is long-lasting, maintains consistent feel from the beginning to the end of use, and offers excellent wiping performance. [Solution] A kitchen towel roll is made by bonding sheets with an embossed pattern and laminating them into two plies, which are then wound into a roll. The sheets have a pattern of irregularities derived from the papermaking process, different from the embossed pattern, and have a specific volume of 7 cm³. 3 / g or more 22cm 3 The invention provides a kitchen towel roll that is less than or equal to / g, has a roll length of 20m to 44m, and when the winding density at the beginning of the roll is a, the winding density in the middle is b, and the winding density at the end of the roll is c, then (a / c) × 100 (%) is 90% to 130% and (b / c) × 100 (%) is 95% to 120%.
