Picture this: a customer waits several days for their order, then opens the box to find a cracked ceramic mug or a cream bottle that has spilled all over the box. What follows isn't just the cost of the wasted product, but also a 1-star review, a refund claim, and a drop in your store's rating.
The problem of goods breaking during shipping is an invisible cost that eats into your profit every day. The good news is that damage-proof packing isn't a matter of luck, but a system that can be planned and repeated. Let's look at 6 methods that actually work.
Why do goods get damaged in transit?
Before solving the problem, you need to understand what a parcel goes through along the way. Your box will be thrown, stacked, vibrated, and pressed down dozens of times before reaching the customer. Impact happens in 3 main ways:
- Drop: the parcel falls from a conveyor belt or a staff member's hands
- Compression: other boxes get stacked on top of it in the delivery truck
- Vibration: shaking throughout the journey causes parts to loosen or rub against each other
The goal of good packing is to absorb all 3 of these forces before they reach the product itself.
6 professional ways to pack goods against damage
1. Choose the right-sized box, neither too loose nor too tight
A box that is too big lets the product move around, while a box that is too small presses the box walls right against the product, leaving no room for cushioning. The principle is to leave about 5 centimeters of space around the product for cushioning material, and to choose corrugated cardboard with a thickness suited to the weight — for example, heavy items should use 5-ply corrugated board.
2. Wrap each item individually, don't let them collide
If an order has multiple items, such as SKU-GLASS-01 (glass) and SKU-PLATE-02 (plate), simply placing them together will cause them to rub and break. Wrap each item with bubble wrap or paper and separate them with a corrugated sheet so their surfaces don't touch directly.
3. Choose cushioning material suited to the product
Not every product uses the same material. Let's compare:
| Product type | Recommended material |
|---|---|
| Fragile items (glass, ceramic) | Multiple layers of bubble wrap + corner foam |
| Liquids (cream, perfume) | Bottle-cap seal + leak-proof bag + bubble wrap |
| Electronics | Precisely cut EPE foam + anti-static bag |
4. Fill all the empty space, don't leave any gaps
Empty space in the box is a fierce enemy, because it lets the product slide and slam into the box walls. Shake the box gently before closing it — if you hear things moving, it means you haven't filled it enough. Use crumpled paper, foam pellets, or air bubbles packed tightly into every nook and corner.
5. Seal the box with the H-Tape technique
Don't tape in just one line. Use the H-shaped taping technique: tape along the center seam, then tape both edges of the box flaps, on both the top and bottom. This method helps withstand compression and prevents the box flaps from opening when stacked.
6. Attach warning labels and take photos before shipping
Attach a Handle with care / Fragile / Do not stack sticker where it is clearly visible, and you should photograph or film the packing of every order as evidence. If a claim occurs, you'll immediately have proof to confirm with the carrier and the customer.
When orders grow, packing standards are the heart of it
The problem most sellers face is that when orders spike during a big campaign or a sale festival, packing by yourself starts to get sloppy, rushed, and inconsistent. The first order is packed tightly, but the 200th order may forget the cushioning. The result is that the damage rate spikes right when sales are at their best.
This is where a fulfillment system like Flash Fulfillment can help, because packing is done to the same standard for every item, whether it's order number 1 or number 1,000. Cushioning materials are specified according to the product type of each SKU, and there's a team that packs systematically, so you reduce damage, reduce claims, and have time to focus on selling and marketing instead.
Key takeaways
- Damage is caused by drop, compression, and vibration. Good packing absorbs these forces.
- Choose the right-sized box, leave cushioning space around the product, and fill the gaps tightly.
- Wrap each item individually, choose materials suited to the product type, and seal the box with H-Tape.
- Take photos before shipping as evidence for claims.
- When orders are high, a repeatable packing standard is the key to controlling quality.

Frequently Asked Questions (FAQ)
Should I use a mailer envelope or a box?
It depends on the product. Items that aren't afraid of compression, such as clothing, can use a padded mailer, but items that break easily or have a defined shape, such as cosmetics and electronics, should always use a corrugated box to withstand compression and impact.
Won't the cost of packing materials be too high?
Compare the cost of cushioning material — just a few baht per box — with the cost of reshipping the product, the repeat shipping fee, and the bad reviews that follow. Investing in good packing is far more worthwhile in the long run.
What should I do if the product is damaged even though it was packed well?
Use the photos or clips from packing as evidence to file a claim with the carrier, and quickly contact the customer to resolve the issue fast. A good response helps preserve the relationship and your store rating.
Can I still control packing standards when using fulfillment?
Yes. A good fulfillment system lets you set the packing requirements for each SKU — for example, which product groups need how many layers of bubble wrap — ensuring that every order is packed to your desired standard consistently.
