Stand-up pouch and doypack
A pouch with a folded gusset in the base that opens out so it stands on the shelf. “Doypack” is the common name for this style. The base seal is often a rounded U shape, sometimes called a round-bottom or Doyen seal.
K-seal
A stand-up pouch where the bottom gusset is sealed at an angle at each corner, forming a K shape. It spreads the weight better, so it suits heavier fills such as protein powders.
Block bottom, flat bottom and box pouch
A pouch with a flat rectangular base and side gussets, so it stands like a box. It has five printable panels: front, back, two sides and the base. It often has a zip and looks premium on shelf.
Flat pouch and pillow pack
A pouch with no gusset, sealed on three sides (or with a back seal and two end seals). It lies flat, so it suits small refill packs and samples.
Common features
Zips and press-to-close seals, tear notches, hang holes, windows, degassing valves, and materials from foil laminates to kraft paper and recyclable mono-polymer films.
What it means for your artwork
- Text in gussets and side folds can be hidden once the pouch is filled. Keep mandatory information on flat faces.
- Keep text clear of seal margins, zips and tear notches.
- The name and net quantity must be visible together, usually on the front.
