Card sleeve

Flat sleeve for gift, loyalty or greeting cards: front with a thumb cut-out at the opening, back at the bottom fold, side seams formed by glue flaps, optional closure flap. Dimensions are the card's insertion dimensions; clearance and flaps make the sleeve larger.

How the shape is constructed

The sleeve joins front and back with a bottom crease. Two glue flaps form the side seams and sit inside on the front after gluing. The starting example has a thumb cut-out but no closure flap. The input describes the card to be inserted.

How it is assembled

Fold the side flaps inwards and apply adhesive to their outside, fold the back over them along the bottom fold and press down. Insert the card; fold the closure flap over the opening onto the front.

Test fit, folding and closure on a sample made from the intended material. Confirm material thickness, grain direction and production steps with your printer.

What to consider for this construction

Clearance

Allowance on each side and at the bottom for easy card insertion; also includes material thickness.

Glue flap

Width of the glue flap used to glue the blank into a tube. The material requires a minimum width.

Glue flap angle

Angle at the ends of the glue flap; makes folding and erection easier.

Thumb notch

Semicircular cut-out centred at the front opening for gripping the card.

Thumb notch radius

Radius and depth of the thumb cut-out; no more than 30 % of the card width and 40 % of the card height.

Frequently asked questions

What do the starting dimensions 85.6 × 54 mm mean?

They describe the card's insertion dimensions, not the finished sleeve's outside outline. The template adds clearance and internal side flaps. The blank is 127.6 × 110 mm in the starting run. Use the actual card dimensions and check the glued sleeve with these contents.

Why does the sleeve grow by the flap width?

After assembly, the side flaps sit inside on the front. The model keeps the usable card width plus clearance free between them. glueFlap therefore affects both the outer blank and sleeve width. Do not change the glue flap without recalculating and checking fit again.

Can I disable the thumb cut-out?

Yes. cardThumbNotch switches the cut-out at the front opening. cardThumbNotchRadius applies when enabled and is also limited by the card dimensions. Without a cut-out, the opening remains straight. Then test removal with the actual card, especially if it extends only slightly beyond the sleeve edge.
