The Gusset Seal design is a composite idea of the other designs. It's a flat style bag made with both sides tucked in to form gussets. Where the bag is indented, it has to be sealed through four layers of film, while the middle of the bag has only two layers. This type of construction means that there is a weakness where leaks can occur. Nevertheless, they are still extremely popular because of the ease of manufacture and good fit inside the garbage bin receptacle.
