What's on this dieline
Seals are not drawn; a 0.25" no-print margin keeps ink off the sealed side edges. A zipper needs a header. Bag width runs along the repeat (across the fold). Cut line, folds (dashed), seal margins and no-print zones on separate spot-colour layers. Artwork: CMYK, 300 DPI minimum, AI or PDF/X-1A. Pouch seal widths and the stand-up bottom curve are standard approximations - confirm against your supplier's template before art approval.
