Custom Kraft Paper Flour Bags for 1–5 kg: Wholesale Stand-Up and Flat Bottom Pouches
Custom kraft paper flour bags from a kraft-laminate structure protect 1–5 kg of flour better than plain paper sacks, because the laminate carries a PE or barrier layer that plain paper does not have.
A plain paper sack passes moisture and offers no sealed barrier against insects. A kraft-laminated stand-up or flat bottom pouch keeps the kraft look and adds a heat-sealed inner layer, a resealable closure and full-colour print. It is a different bag from a bakery paper sack, and it suits retail shelves as well as home baking.
We make these bags to your size, material and artwork, with printing, lamination and bag making in our own cleanroom plant in Shenzhen. Digital print starts at 1,000 pcs per design. Gravure starts at 10,000 pcs per design.
- Sizes — Made to your fill weight, from 1 kg to 5 kg, confirmed in the quote.
- Print — Digital or gravure, with your logo and artwork or a free layout from our design team.
- Sample — Free sample of a similar bag. You pay the courier.
Barrier structure
Moisture, Pests and Shelf Life: Does a Kraft Flour Bag Protect Your Flour?
Kraft paper alone does not protect flour. The inner layers decide.
Where plain kraft fails
Uncoated paper takes up humidity and lets odours and insects reach the flour. Flour in humid storage can clump, and pests can enter through unsealed folds. A laminated pouch with a heat-sealed PE inner layer closes those routes, because the seams are sealed rather than folded.
PE liner, foil or high-barrier laminate
Kraft with a PE liner usually suits plain wheat flour with a normal shelf life and dry storage. Foil or high-barrier laminate suits longer freshness targets, humid destination markets, or flours with higher fat content such as wholegrain or nut flours. Foil adds cost and hides the contents unless you add a window. We recommend a structure from your flour type and target shelf life. Specific barrier figures are confirmed in the quote.
Choose the structure by flour type and target shelf life, not by the kraft look alone.
Closing a Flour Bag: Zipper, Tin Tie, Fold-Over or Heat Seal
The closure decides how the bag is used after the first opening.
Zipper and tear notch
A zipper suits home bakers who open the bag many times over weeks, and it works on a retail shelf where the pouch stands upright. A tear notch gives a clean first opening. We offer both on stand-up and flat bottom pouches.
Heat seal only
A heat seal without a zipper suits distributors who repack flour into other containers, or single-use bakery packs. It costs less and is the simplest to fill. Tin tie and fold-over closures are not part of our listed options, so ask in the quote if you need one.
Sizing Kraft Pouches for 1 kg, 2 kg and 5 kg of Flour
Bag size follows flour density and how you fill.
Density, filling and bag style
Flour packs loosely when poured and settles after filling and tapping, so a bag sized only by volume often ends up too tall or too slack. Fill weight, how you fill (manual or machine) and how much headspace you leave for sealing all change the final dimensions. For 1 kg and 2 kg packs, stand-up pouches work well on retail shelves. For 5 kg, a flat bottom pouch gives a more stable block shape.
Our free Pouch Capacity calculator gives a starting size with no sign-up. We confirm exact dimensions in the quote from your product and fill weight, and the sample lets you check the fit before production.
Custom Printed Flour Bags With Logo: Material, Window, Print and Extras
Every part of the bag is made to your specification.
-
Size and material
Custom dimensions in kraft paper laminate, with foil or high-barrier layers where your shelf life target needs them. The structure is recommended in writing.
-
Digital or gravure print
Digital print suits launches and several flavours or flour types. Gravure suits repeat volumes. The number of colours is itemized on the quote.
-
Window, zipper, hang hole, tear notch
A window shows the flour colour on the shelf, and a zipper makes the bag resealable. Each extra is priced as its own line.
-
Artwork
We reproduce finished files, or our design team lays out your bag from an idea or a reference photo at no charge.
Flour Bag Minimums: 1,000 Pcs Digital, 10,000 Pcs Gravure
Choose the print method by order size and how often you reorder.
-
Digital print, 1,000 pcs per design
No printing plates and no plate cost. It suits new product trials, several flour types or flavours in one order, and test runs before a larger commitment.
-
Gravure print, 10,000 pcs per design
Cylinders are made once and reused on reorders, which lowers the unit price on repeat volumes. A one-time cylinder charge applies per colour.
