Our kraft paper bags are self-opening sacks: a rectangular base, side gussets, and an open mouth, cut straight or serrated, that springs open and stands upright while an order is packed. The blank stores flat and opens in one motion, so a busy counter can keep a stack within reach. Buyers order the same construction as paper lunch bags for a single meal, as paper grocery bags for baked goods, and as food paper bags for pharmacy or supermarket counters. Brown and white kraft, plain or plastic-lined, both take CMYK or PMS print across every panel. Trade catalogues call these SOS bags, and the sheet is cut to your dimensions rather than a fixed size list.

Square Base, Side Gussets, and Top-Edge Options

The shape does the work. A rectangular bottom panel is folded and glued so the bag sits square on the counter instead of rolling onto its side, while two gussets run up the flanks to give the body depth as it fills. The top edge can be cut straight or serrated, and either finish gives the print a defined stopping line. Because the sheet is creased before forming, the folds stay straight and the bag returns to the same footprint. Set base width, gusset depth, and height from what you actually pack, and we cut the blank to those three figures. A single run of paper grocery bags can then cover a small pastry order and a full family meal.
Kraft, Lined Paper, and Food-Contact Performance

Both stocks start as food-grade kraft, with thickness matched to the load. Unlined brown or white kraft suits dry bakery items, sandwiches, and boxed food, and stays recyclable. Where an order is oily or carries moisture, a plastic-lined sheet adds a barrier on the food-facing side so grease does not wick through and dull the printed panel. FSC chain-of-custody documentation is available if your own packaging claim must be audited. Ink sits on the outside only. Tell us the item and how long it sits in the bag, and we will match stock and lining on our own test line. For food paper bags across a mixed menu, that is the specification to settle first.
Full-Bleed Print on a Flat Panel

Printing happens while the sheet is still flat, before any crease or glue is applied, so a solid colour can run from the base fold to the top edge without stretching at a corner. CMYK covers photographic work and all-over patterns; PMS holds a brand colour to one reference across reorders; unprinted kraft stays an option for a plain natural look. The gallery runs from a full color repeat to a single dark logo and a checkerboard base band. Small marks such as allergen notes stay legible because the panel is flat when printed. Keep critical type clear of the crease zones, and we will position the artwork to the dieline we cut for your paper lunch bags.
Made-to-Order Sizes, Samples, and Repeat Runs

Every dimension is open: width, gusset, and height are set to the contents, so one artwork can be scaled across two or three formats and still read as one family on the shelf. In-stock samples are free, and a printed proof can be turned around in three days, which is enough time to load the real order and check the base before committing. Production starts at 20,000 pieces and takes 15–25 working days once the artwork is approved. Colour references, dieline, and paper lot are logged against the approved proof, so the SOS bags you reorder six months later match the first delivery rather than drifting a shade. Cutting, printing, bag making, and inspection all sit in one production plan.
