Same one-piece blank as a straight tuck-end, but the top and bottom flaps tuck from opposite sides. On taller cartons this is what stops the two flaps fighting each other when the pack is closed.
Where it fits
Tall and slim formats — bottle cartons, 30-day supplement packs, tea and coffee — where a straight tuck-end would need 400 gsm just to stop the flaps buckling.
What you can specify
- Dimensions — built to your product, no fixed size range.
- Board — 300–400 gsm FSC-certified folding boxboard (GC1 or SBS); 350 gsm is usual, because the opposite-side tuck already adds rigidity that a straight tuck needs extra board to reach.
- Printing & finish — offset CMYK plus Pantone; the front and back panels are printed as one sheet, so a design that wraps around the side seam needs the artwork set up for it.
- Structure — one-piece reverse tuck blank with opposite-side flaps, glued on one seam.
What decides the price
Height relative to width. The taller the carton, the more the reverse tuck earns its small extra board cost over a straight tuck.
