ABS vs Polypropylene Luggage — Which Should You Choose?

Should you choose an ABS or polypropylene (PP) suitcase for your next trip from the UK? Both are used in hardshell luggage. The material matters, but it cannot tell you on its own which finished case weighs less, lasts longer or handles baggage treatment better. Compare the particular cases you're considering.
What is ABS?
ABS stands for acrylonitrile butadiene styrene. It is used in a range of rigid luggage shells, including some KONO cases. How an ABS case performs depends on its design, shell thickness and construction, as well as its wheels, zip and handles. Do not assume that all ABS cases weigh the same, resist knocks equally or crack under the same conditions.
What is polypropylene?
Polypropylene, often shortened to PP, is another plastic used for suitcase shells. It can be formed into flexible designs, but that does not mean every PP case will spring back after an impact or outlast an ABS case. The total weight and price of a finished suitcase depend on more than the shell material.
Compare the finished cases, not just the labels
| Question | What to check on each ABS or PP case |
|---|---|
| Weight | The listing's stated empty weight for the same size; PP is not automatically lighter. |
| External size | Full measurements including wheels and handles, not just the inch label. |
| Construction | Shell design, closure, corners, wheels and handles; material alone does not prove durability. |
| Price | Current prices of the specific cases you would buy, rather than an assumed material premium. |
| Features | The actual lock, layout, wheel type and any expansion feature on that model. |
Which should you choose?
If two cases suit your trip, compare their listed specifications and what you find practical to carry. An ABS case might be the better choice for you; a PP case might be. Neither material is reserved for occasional or frequent travellers, and neither guarantees a particular lifespan. A more expensive case is not automatically stronger. Read the individual product listing and its Manufacturer's Warranty terms.

Before buying for a flight, check your booking confirmation and the operating airline's latest baggage rules. Compare the case's full external dimensions, including wheels and handles, and its packed weight with your actual allowance. Our cabin-bag guide has more airline-specific points to check. Delivery offers can change, so check current terms at checkout.
