Video transcript

1. 0:00Tuck boxes look alike closed, but behave very differently.
2. 0:05Each tuck box is one die-cut sheet, glued at one side seam and shipped flat. Friction keeps the ends shut: tucks press against dust flaps, slit locks add grip.
3. 0:17Straight tuck closes both ends one way, keeping the front clean. Reverse tuck closes them opposite, so blanks often nest better, but a cut edge shows up front.
4. 0:28For heavier products, change the bottom. Auto-bottom is pre-glued and sets up in one motion. Snap-lock needs no pre-glue, but every bottom is locked by hand.
5. 0:39To choose, weigh the filled product, decide how much the front matters, match your packing line, check food-contact and child-resistant needs, and plan end of life.
6. 0:50When a clean front matters most, start with straight tuck.
