Pinch bottom bags have only stitching at the bottom and closure at the bottom. And there’s no handle. Once the bag is filled, a pinch sealer closes the bag by activating pre-applied glue on the bag’s opening with hot air, folding the open end over to complete the closure, and pinching the fold closed until the glue cures.
The following video will help you learn the specific details about the pinch bottom bag.
