FLUID-FILLED CUSHIONING ARTICLE WITH SEAMLESS SIDE WALLS AND METHOD OF MANUFACTURING

A method of manufacturing a cushioning article comprises the steps: wrapping a polymeric sheet around a support so that the polymeric sheet surrounds a perimeter of the support. A first portion of thepolymeric sheet adjacent a first side edge of the polymeric sheet overlaps and is stacked on a second portion of the polymeric sheet adjacent a second side edge of the polymeric sheet. The first portion is welded to the second portion at a first weld disposed between the first side edge and the second side edge while the polymeric sheet is wrapped around the support so that the polymeric sheet forms an open-ended sheath with a top wall, a bottom wall, a first side wall and a second side wall with the first weld disposed at only one of the top wall and the bottom wall. A cushioning article manufactured according to the method is disclosed. 一种制造缓冲制品的方法，包括将聚合物片材包裹在支撑物周围，以使聚合物片材围绕支撑物的外围。邻近聚合物片材的第一侧边缘的聚合物片材的第一部分重叠并且堆叠在邻近聚合物片材的第二侧边缘的聚合物片材的第二部分上。在将所述聚合物片材包裹在所述支撑件周围的同时，在设置在所述第一侧边缘和所述第二侧边缘之间的第一焊接部处将所述第一部分焊接到所述第二部分，以使所述聚合物
