BAG CATALOGUE
Bag structure templates.
Eight parametric bag structures across three construction series. Configure the panel, gusset and height dimensions and inspect the flat blank and its folded form from the same parametric model.
A bag is a dieline too
It is easy to think of bags as sewn or wrapped rather than engineered — but a paper bag is a die-cut and folded blank like any carton: front and back panels, side gussets, a base that folds into shape, and glue areas that hold the tube together.
Seen as a dieline, a bag becomes precise: gusset depth, base overlap and top finish are all measurable decisions rather than guesses, and they interact with each other as real geometry.
Three construction series
The catalogue's eight bag structures span three construction series, each with variants at different proportions. Open a template to see which panels and folds define it and which dimension parameters its construction supports — every value is validated against the structure's real range.
As elsewhere in the catalogue, nothing here is a static download: the blank regenerates from your dimensions.
Gussets and the base fold
The character of a bag lives in its gussets and base. Side gussets let the bag expand to hold volume and fold flat for storage; the base construction decides whether it stands open on the counter or folds away to nothing. These are also the areas where geometry most often goes wrong — a base whose folds don't close cleanly, or gussets out of proportion to the opening.
Because the parameters drive the whole structure, changing a gusset or base dimension updates every dependent panel in the blank at once.
Material and direction
Bags are typically converted from kraft papers whose weight and grain direction affect how folds set and how much load the finished bag carries. Handle and closure choices add their own reinforcement needs at the top edge.
As with every structure in the catalogue, treat the generated dieline as the structural starting point and confirm paper grade, grain and reinforcement details with your converter before production.
Where the artwork lives
A bag is also a print product, and the dieline is where artwork decisions become real. The front and back panels are the primary print surfaces; gussets fold away and reappear as the bag opens, and the glue seam runs through one panel — artwork that ignores it ends up with a logo interrupted by the joint.
Laying artwork out on the structural dieline, rather than on a flat rectangle, is what keeps brand elements clear of folds, seams and turn-ins. Generate the blank at your real dimensions first, then hand that exact geometry to the artwork stage.
Flat logistics, standing presence
One of the bag's quiet advantages is that it lives two lives: flat in storage and transport, dimensional at the moment of use. That dual life is a structural requirement — the same folds that let the bag collapse must let it stand square when opened, which constrains how gussets, base and panels can relate to each other.
When you evaluate a structure, think in both states: how the flat blank nests for converting and shipping, and how the opened bag presents at the counter. A proportion that optimizes one can quietly compromise the other, and comparing variants of the same series is the fastest way to see the trade-off.
See the fold before you cut
Base formation is the hardest part of a bag to judge from a flat drawing. The 3D preview folds the same parametric structure the dieline comes from, so you can watch the base close and the gussets set before any cutting die is made.
Pick a structure below, enter your dimensions, and inspect both views in the browser — and if your product also needs a box, the FEFCO and ECMA families are configured from the same kind of parametric models, so dimensions carry over cleanly between structure types.
