ABS
ABS is the most scratch resistant under the suitcase materials. The material ensures that the case is resistant to scratches. Also, a case of ABS will take back its shape quicker after it has a dent. Most ABS cases are lightweight so you have more weight for your luggage. A case made of ABS is not the strongest or the lightest. But this material is generally cheaper Than Polycarbonate or Polypropylene .

Scratch resistant
Flexible and pliable
Polypropylene
Polypropylene is one of the strongest materials and is therefore also used in making Curv. The hard shell can withstand a strong impact. It is a good alternative for travelers who find the bags made of polycarbonate or Curv too expensive. The disadvantage of polypropylene is that it is often heavier than other materials in this list.

Polycarbonate
A polycarbonate case also has many advantages, just like Curv. The unique thing about polycarbonate is that it is flexible in addition to being very strong and lightweight. Handy while packing, the material will dent. It is unfortunately somewhat more scratch-sensitive than a case of ABS, but that material is less firm.
