A bulky sheet () has a first side (), a second side () opposite to the first side (), a plurality of macroscopic first recessed ridges () and a projection () on at least the first side (). The first recessed ridges () extend straight in a first direction at a predetermined interval. The projection () is located between the first recessed ridges () adjacent to each other. The projection () projects from the second side () toward the first side () of the bulky sheet ().

A moist wipe package 1 comprising moist wipes 11 and a storing body 12 for storing the moist wipes 11 therein, the storing body 12 having a generally rectangular parallelepiped body formed from a generally square sleeve-like packing material whose opposite ends are open, an outlet opening 13 through which said moist wipes 11 are withdrawn being formed in one surface 12a of the packing material, opposite side edge portions 12a', 12a' of one surface 12a and/or opposite side edge portions 12b', 12b' of the other surface 12b opposing the one surface 12a being enhanced in rigidity so that they may have self-supporting properties, and the one surface 12a and the other surface 12b being sealed at the opposite ends, the sealed opposite ends 12d, 12d being fixed so that the one surface 12a forms opposing two end faces 12e in the generally rectangular parallelepiped body.

A parison thickness control system includes an extruder die and a mandrel which are movable relative to each other to change wall thickness of a parison extruded between the extruder die and the mandrel during an extrusion or forming cycle of the parison. A parison control pattern is derived by manually inputting master points each defined in terms of a target parison wall thickness and an elapsed time during the parison extrusion cycle. A further parison control pattern is derived by performing the spline interpolation to interpolate between the master points. A still further parison control pattern is derived by correcting the above-noted further parison control pattern to allow the maximum or minimum value of the master points to indicate a limit value for the target parison wall thickness during the parison extrusion cycle. The parison extrusion cycle is divided into a given number of equal time intervals to define cycle points. The target parison wall thickness is derived for each cycle point based on the above-noted still further parison control pattern. The relative movement between the extruder die and the mandrel is controlled based on the derived target parison wall thickness for each cycle point. At least one of the cycle points may be used for triggering operation of an associated device.
