ABS or polycarbonate suitcase: which do you choose?
Short answer: polycarbonate is usually the better choice if you are looking for a hard suitcase that needs to withstand a lot. The material generally flexes better when exposed to impact and is less likely to crack or split than ABS. If you mainly want a more affordable hard-shell suitcase for occasional travel, ABS is more than sufficient for many people.
You notice the difference especially while travelling. With checked luggage, frequent flights and rough baggage handling, extra flexibility and impact resistance become more important. If you travel less often, the lower price of ABS often matters more. However, keep in mind that the material label does not tell the whole story. An ABS+PC blend is different from pure polycarbonate, and there are also clear differences in quality within polycarbonate itself.
How these two hard-shell suitcase materials differ in practice
Which is better, ABS or polycarbonate? In practice, polycarbonate usually performs better in terms of strength, flexibility and resistance to hard impact. ABS remains popular because it often keeps the starting price of a hard-shell suitcase lower. The overview below shows what you notice when packing, lifting and travelling.
| Aspect | ABS | Polycarbonate | What do you notice in use? |
|---|---|---|---|
| Impact resistance | Sturdy, but absorbs impacts less effectively | Generally flexes better on impact | With checked luggage, polycarbonate is usually less likely to crack or split after hard impacts. |
| Flexibility | Relatively stiffer and harder | More flexible without giving way quickly | Pressure on the shell is often distributed better, which is useful with full suitcases and during transport. |
| Weight | Often lightweight, depending on the construction | Also lightweight, especially in better-designed models | For hand luggage, every bit of weight saved is welcome, but the suitcase's construction matters just as much. |
| Price | Usually more affordable | Usually more expensive | ABS is attractive if you want a hard-shell suitcase without immediately paying more for intensive use. |
| Visible signs of use | Scratches are possible, and the finish makes a big difference | Can also show signs of use, especially glossy shells | A matte or textured finish often shows superficial scratches less quickly. |
| Temperature resistance | Less forgiving when temperatures vary greatly | Generally remains more stable and flexible | Useful if you fly or travel frequently between cold and warm destinations. |
| Feel when packing and lifting | Fine for normal use | Often feels more secure under heavy loads | With a full suitcase, polycarbonate often gives you a little more confidence in the shell. |
| Most often chosen for | Occasional holidays and budget-conscious choices | Frequent travel and more intensive use | Your choice mainly depends on how often you travel, your budget and whether the suitcase is often checked in. |
That is why there is no single winner for everyone. For light and limited use, ABS can be a very logical choice. If you expect your suitcase to be under a lot of strain, polycarbonate is usually the safer choice in the long term.
When an ABS suitcase is a smart choice
An ABS suitcase is a hard-shell suitcase made from acrylonitrile butadiene styrene, a widely used plastic material that you often see in affordable hard-shell suitcases. It is popular because it looks sturdy, protects the contents well against normal external pressure and usually keeps the price friendlier than suitcases made from pure polycarbonate.
For normal and less frequent use, ABS is often simply a smart choice. If you take a few trips a year, want a hard shell and do not expect your suitcase to go through intensive baggage handling every time, ABS will often serve you well. Especially if your budget is an important factor, it is a sensible material to consider. In that case, explore our affordable suitcases.
The main limitation is how the material handles hard impacts. ABS is less flexible than polycarbonate and absorbs shocks less effectively. This increases the risk of damage if a suitcase is thrown, heavily loaded or frequently checked in. If you mainly want an affordable hard-shell suitcase for occasional travel, ABS is often a good fit. If you expect heavier or more frequent use, it is worth looking further.
When polycarbonate is the better investment
Polycarbonate is often seen as the stronger and more flexible choice for hard-shell suitcases. You notice this especially when a suitcase is frequently on the move. The material can flex better on impact, making the shell less likely to crack or split when it is under heavy strain. That is why many travellers who use their suitcase intensively choose polycarbonate.
The practical benefits are clear: better shock absorption, more resilience and generally more stable performance when temperatures change. This is particularly useful for checked luggage suitcases, because you have little control over how your suitcase is handled. If you pack more heavily or change planes often, a polycarbonate shell can also give you greater peace of mind.
There is a downside, however. The price is usually higher than for ABS, and depending on the finish, signs of use may remain visible, especially on glossy shells. Even so, the extra cost often makes sense if you fly regularly, frequently check in your suitcase or simply want to rely on a hard-shell suitcase for longer that can handle more than average holiday use.
Do not be misled by the label: blends and differences in quality
Looking only at the word “polycarbonate” or “ABS” is too simplistic. Many hard-shell suitcases are not made from one pure material, but from a blend. An ABS+PC blend combines ABS with polycarbonate to achieve a certain price level and specific properties. This can be a good middle ground, but it is not automatically the same as a suitcase made entirely from polycarbonate. Such a blend is often chosen to reduce costs, and its exact performance varies by model. For example, compare suitcases within one brand range, such as American Tourister suitcases, so you can compare materials and finishes side by side.
There are also major differences in quality within polycarbonate itself. Not every polycarbonate suitcase feels or performs the same. The quality of the raw material, the shell thickness, the layer structure and the production process all affect durability. A thin shell with an attractive label may be less convincing in practice than a better-built suitcase with a well-designed construction. In other words, the material is important, but the construction also determines how strong a suitcase really is.
This also explains why price differences are not caused by the shell material alone. You are often paying just as much for the overall finish: a sturdy zip or frame, smooth-rolling wheels, a stable handle, solid grips, a practical interior layout and the warranty conditions. Two suitcases with the same material in the product title can therefore feel very different and perform very differently while travelling. If you want maximum strength, also consider aluminium suitcases as an alternative to ABS/PC.
If you compare carefully, look beyond marketing language, including in lists of the Best suitcases 2026. Press the shell lightly and see whether it flexes in a controlled way instead of feeling completely rigid. Check whether the suitcase remains sturdy when it is open and empty, how smoothly the zip runs or how solidly a frame closes, and whether the wheels have little play and roll evenly. Fully extend the handle to see whether it remains stable. Finally, check the corner finish, interior pockets, packing straps and overall finish. This gives you a much more realistic view of the quality than the words ABS or polycarbonate alone.
How to choose the right material for the way you travel
The best material for a suitcase cannot be separated from how you use it. The right choice is always a balance between price, weight, strength and the way you travel. Use this simple guide to decide more quickly whether ABS or polycarbonate suits you better.
- Choose ABS if you mainly want an affordable hard-shell suitcase and only travel occasionally. For a few holidays a year, the material is often more than sufficient, especially if you do not expect the suitcase to be constantly heavily loaded or handled roughly.
- Choose polycarbonate if you travel often, fly regularly or frequently check in your suitcase. In that case, impact resistance becomes more important, and the extra flexibility of the shell usually makes the difference between simply travelling with a usable suitcase and travelling with real peace of mind.
- If you mainly use the suitcase as hand luggage, low weight often matters more with lightweight suitcases than maximum impact resistance. Both ABS and polycarbonate can be suitable, but check the total weight, the outside dimensions and how efficiently the suitcase is organised.
- If you usually use the suitcase as checked luggage, strength under real travel conditions is more important. Polycarbonate usually has an advantage here because it handles impacts and pressure better during loading, unloading and transport on conveyor belts.
- If you often pack heavily or want to use the same hard-shell suitcase for longer, polycarbonate is usually the more logical investment. If you mainly want a neat, hard-shell suitcase for normal use without spending too much, ABS remains a perfectly reasonable choice.
- Never compare suitcases based on material alone. Always also look at the size, capacity, interior layout, zip or frame, wheels and handle. This makes it easier to determine which suitcase size is suitable for 20, 23 or 25 kg.

So what is the best suitcase for air travel? For hand luggage, a lightweight and practical suitcase is often the smartest choice. For checked luggage, a more impact-resistant shell becomes more important. If you are choosing between two hard-shell suitcases, do not compare them only by price or material name. Consider how well they fit the way you travel. That usually leads to the best choice.
