Protection
Protective Mailers
Products arrive damaged for four different reasons, and cushioning only fixes two of them. Buying a padded mailer when your problem is crushing or movement means paying more for the same failure rate.
This page sorts the options by the failure they address. Start from how your damaged items actually failed and read across.

Read the detailStart from how things are failing
Look at the damaged items rather than at the packaging. The way they broke tells you what to buy.
| What you are seeing | The cause | What fixes it |
|---|---|---|
| Cracked, chipped, broken | Impact | Bubble lining |
| Scratched, scuffed, marked surfaces | Abrasion | Foam lining |
| Crushed, deformed, flattened | Load from above | A rigid carton — not more padding |
| Damage at corners and edges only | Concentrated force | Box the item first, then cushion |
| Contents rattling, damage inconsistent | Movement inside the bag | A smaller mailer, or fill the space |
| Water marks, damp packaging | Weather exposure | A film outer rather than paper |
The honest limits of a flexible bag
A mailer has no structure. Whatever load is placed on top of it goes straight through to the contents, and no lining changes that. If your products are being crushed rather than knocked, the answer is a carton and it is worth accepting that early rather than working through three cushioning specifications first.
The second limit is fit. Cushioning protects where it sits between the contents and the outside. A small item in a large padded mailer has protection on its faces and open space beside it, and it will reach the end of that space at speed.
Get both of those right and cushioning does the rest of the work well.
Questions about protective mailers
Which protective mailer is strongest?
There is no single strongest, because impact, abrasion and crushing are different failures. Bubble absorbs impact, foam protects surfaces, and neither resists a load pressing down — that needs a rigid carton.
Do I need to box items inside a protective mailer?
For anything genuinely breakable, yes. Cushioning absorbs impact across a face but does not protect an exposed edge or corner. A boxed item inside a cushioned mailer is a far more reliable combination than either alone.
Are protective mailers cheaper than boxes with void fill?
Usually, per parcel, and they weigh and measure less as well. Where contents need structural protection, though, the comparison is not really available.
