Quick answer: use 2-inch (1.88 in) heavy-duty clear packing tape in a handheld tape gun. Tape the box with the H method: one strip along the centre seam and one across each edge seam, top and bottom.
Our top picks
Tape types
| Type | Good for | Notes |
|---|---|---|
| Hot melt (most “heavy duty” tape) | Corrugated boxes, fast sticking | Strong initial tack; the common default |
| Acrylic | Cold or hot storage, long storage | Bonds more slowly; ages well |
| Paper / water-activated | Premium or plastic-free packaging | Needs a dispenser that wets the tape |
How to tape a box (H method)
- Run one strip along the centre seam, extending about 2 to 3 inches down each side.
- Run one strip across each open edge seam.
- Repeat on the bottom. For heavy boxes, add a second centre strip.
- Never tape over the shipping label barcode; carrier scanners struggle with glare.
Common mistakes
- Thin “economy” tape that splits on recycled boxes.
- Using parcel tape on dusty boxes; wipe or use a fresh box.
- Covering FBA or WFS box labels with tape.
