Home > Guides > Packing fragile items
Pack fragile items in a box inside a slightly larger box, cushion every side, and tape every seam. Then assume the parcel gets tossed, stacked, and sorted by machine, because it does. "Fragile" stickers do not buy gentle handling. First, the honest part: LetterAgent only sells the shipping label. The packing is your job.
A sturdy new or nearly-new corrugated box (old boxes fail along their creases, which is where the strength was), a second larger box, cushioning material, and wide packing tape. For cushioning, bubble wrap beats newspaper: newsprint crushes flat under weight and stops protecting, while bubble wrap keeps its air pockets. Crumpled kraft paper sits in between and works fine for filling voids. You will also want a marker and your shipping label. String, twine, and ribbon have no place here: carriers will not accept parcels tied with string because it jams sorting machinery.
Wrap the item itself in two layers of bubble wrap, taped so it cannot unwrap. Place it in a snug inner box with cushioning filling every gap, especially the corners: corners take the hits. Then put that box inside a larger outer box with at least 5 cm of cushioning on all six sides. The air gap between the boxes is the whole point. A single sharp impact gets absorbed by the outer box and the cushioning before it ever reaches the inner one.
Seal the outer box with the H-taping method: one strip down the centre seam, then strips across both edges, so the tape forms an H. Most box failures happen because only the centre seam was taped and the flaps peeled open under a stack of heavier parcels. Your parcel will sit under other parcels. Tape like you know that.
Close the box, seal it, and shake it. If anything inside moves, rattles, or shifts, open it back up and add more cushioning until it doesn't. Movement is what kills fragile items: an item that slides can build momentum and smash itself against the box wall from the inside, and no amount of external padding saves it. The shake test takes ten seconds and catches the failure mode behind most breakage claims.
Two refinements. First, immobilize the item inside the inner box so the bubble wrap is compression, not decoration: wrap tightly and tape the wrap to itself. Second, fill the voids in the outer box with material that does not settle. Loose packing peanuts migrate downward during transit and leave the top unprotected; crumpled paper or air pillows stay put better.
Because parcels move through automated sorting equipment, and machines cannot read. Belts, chutes, and robotic arms handle thousands of parcels an hour, and "this side up" arrows are equally ignored. A sticker is a request made to a human who never touches your parcel.
The sticker is not useless, just mispriced. It may earn your parcel slightly more care at the two points where a human does handle it: the drop-off counter and the final delivery. But the damage happens in the middle, at the sort facility, where orientation is whatever the conveyor decided. Pack for the machine, not the sticker. And if the contents are glass, ceramic, or genuinely irreplaceable, buy declared-value coverage too: proper packing prevents most damage, but it cannot prevent all of it.
| Failure | Why it happens | The fix |
|---|---|---|
| Item moves inside the box | Gaps in cushioning let it build momentum | Shake test; fill every void |
| Box crushes under a stack | Weak or reused box, single-taped seams | New corrugated box; H-taping on all seams |
| Corners punctured | Corners are the structural weak point | Extra cushioning at corners in the inner box |
| Water damage | Rain on loading docks and open truck beds | Wrap the item in a plastic bag inside the box |
| Label torn off | Label on a seam or edge catches and peels | Label flat on the largest face; tape over it with clear tape |
The plastic-bag trick deserves emphasis because it costs nothing: a kitchen garbage bag around the inner box protects against the rain your parcel will inevitably meet on a loading dock. Water damage is the most preventable loss in shipping and the one people skip most often.
