A vertical form fill seal, stand-up, bag and a method of making the same is disclosed. The bag made of a flexible and resilient material such as plastic, has hollow interior, a horizontal bottom seal located below the hollow interior and a top horizontal seal located above the hollow interior. The bag can stand, preferably on or near the bottom seal, when filled with contents. A recloseable seal, such as a finger closure zipper or a slide zipper in other embodiments, is on a perimeter of the hollow interior, and between the top and bottom seals. The recloseable seal extends in a direction other than horizontal, and may extends the entire distance, or only a part of the distance, between the top horizontal seal and the bottom horizontal seal. The recloseable seal is fixed to sealed horizontal sides, or other than the sealed horizontal sides, and may be flush with the bag or extending beyond the edges of the bag. The bag has a handle above the top horizontal seal.
