Rounded corners

Rounded corners are pouch corners cut to a defined radius rather than left as sharp 90-degree points. The curve is cut during pouch making with a dedicated corner knife.

Why it helps

• Laminated film corners can be stiff enough to scratch; rounded ones feel safer, which matters for children's and frequently handled products.
• Packs in a case or on shelf are less likely to scratch or puncture each other.
• Soft lines give a more finished, premium look.
• Sharp corners are common tear-start points, and a curve removes that weak spot.

Common uses

Baby and children's products, cosmetic samples and sheet masks, medical items and wipes, sachets, and premium coffee, tea or snack pouches.

Things to check

Choose the radius together with the seal width; too large a radius narrows the seal at the corner and can weaken it. Keep text and graphics inside the safe zone on the dieline, because elements near the corner may be trimmed away. Rounded corners are easy on three-side seal pouches and doypacks, while gusseted, corner-sealed formats may allow them only on some corners. For a fully custom outline, look at a shaped pouch.
