Custom arch shaped foil pouches are die-cut from aluminum foil laminate, so the curved outline, hang hole and barrier layer are built into one bag.
The arch top needs its own cutting die, and the fill volume, hang-hole position and seal width are set around that outline. The foil laminate blocks light, oxygen and moisture, which suits powders, drink mixes, candy and snacks that sit on a hang shelf for months.
Size, material and artwork are custom. Digital print starts at 1,000 pcs per design and gravure at 10,000 pcs per design. We quote within one business day, and similar sample bags are free.
A curved outline cannot be cut on a standard straight-edge bag line, so each shape gets its own die.
The pouch is printed and laminated as a flat web, then die-cut to the arch profile after the seals are formed. The die-line is approved together with the artwork, and lead time for shaped pouches runs 7–15 days after that approval. Seal width follows the curve, so the artwork safe zone is drawn inside the contour, not the rectangle around it.
A deeper arch reduces the usable corner volume at the top, so the body is usually made slightly taller to hold the same fill weight. Size is set from your product and fill weight, and we confirm the final dimensions on the sample. With digital print, several flavors or SKUs can share one die.
Each option changes the seal layout, so we fix them on the sample.
The hole sits in the top seal, set back from the edge so the seal is not weakened. Round, oval or euro-slot cutouts are possible. The final distance is confirmed on the sample against your peg or rail.
A zipper suits products opened more than once. On an arch top, it sits below the curve on the straight section, which sets the minimum bag height. Single-serve packs usually skip it.
Notches are placed on the side seal, clear of the curve, for easy opening. They are common on sachets and sample packs.
A window shows the product, but it reduces the foil barrier in that area. A degassing valve is for fresh coffee. Both are confirmed in the quote.
Fancy shape and arch bags help stand out on a rack. Mylar or foil is chosen by shelf life, and a zipper is added if the pack is resealed.
Moisture and oxygen are the main risks, so foil laminate with a zipper is the usual choice.
Small foil sachets with a tear notch, sized for the single-serve fill.
Digital print at low quantity lets you test several designs before committing to gravure.
