Abstract
The top of a flexible pouch is sealed when two heated bars are pressed into engagement with opposite sides of the pouch. One of the bars is formed with two angled surfaces which converge into intersecting relation with one another so as to drive moisture from the seal area and enable the formation of a substantially blemish-free seal.
