A method for manufacturing a connected packaged product is characterized in that a tubular continuous sheet (4 b) containing a plurality of absorbent articles (3) conveyed in a conveying direction is provided with a front and a rear of each absorbent article in the tubular continuous sheet (1) including a packaging bag (2) containing a packaging bag containing an absorbent article, a plurality of packages (2) being connected in one direction, is manufactured by joining in a transverse direction to form a lateral joining part. The manufacturing method is a tubular continuous sheet containing a plurality of absorbent articles, and includes a pon corresponding to an end pon of the tubular continuous sheet in the conveying direction of the absorbent article and a pon corresponding to the end of the tubular continuous sheet A step of supplying a cylindrical continuous sheet provided with an air vent hole between the end pon and a pon where a lateral joining pon opposed to the end pon is formed, a step of supplying a tubular continuous sheet extending in a transverse direction to the supplied cylindrical continuous sheet And forming a lateral joint pon. In the method of manufacturing the connected packaged product, excessive air in the packaging bag can appropriately escape when forming the lateral joining pon.連結包装製品の製造方法は、搬送方向に搬送される複数の吸収性物品(3)を内包した筒状の連続シート(4b)に、その筒状の連続シートにおける各吸収性物品の前後をそれぞれ横断方向に接合することにより横接合部を形成して、吸収性物品を内包した包装袋を含む包装品(2)が複数個一方向に連結されてなる連結包装製品(1)を製造する。その製造方法は、複数の吸収性物品を内包した筒状の連続シートであって、筒状の連続シートにおける吸収性物品の搬送方向の端部に対応する箇所と、筒状の連続シートにおけるその端部に対向する横接合部が形成される箇所との間に、空気抜き穴が設けられた筒状の連続シートを供給する工程と、供給された筒状の連続シートに横断方向に延在する横接合部を形成する工程と、を備える。連結包装製品の製造方法は、横接合部の形成に際して包装袋内で余剰となる空気を適切に逃がすことができる。
