Abstract:
A compound heat seal structure that, when heat-sealing a bag with a stacked area level difference, reliably seals even a section having different level and that can be easily opened. A compound heat seal structure is provided as a peelable seal in a band shape on a bag and a linear heat seal is added as a peelable seal in that band-shaped peelable heat seal in the longitudinal direction thereof.
