A film edge sealing device is disclosed herein which has a groove defining a base. The base of the groove of the edge sealing device is oriented at a skewed angle with respect to a longitudinal direction of the conveyor of the heat sealing machine. Edges of a thermoplastic sheet or two stacked layers of thermoplastic sheets are introduced into the groove of the edge sealing device and placed in contact therewith to both heat and melt the edges of the thermoplastic sheet(s) to form a bead and join the edges thereof to form an edge bead seal.
