Having a good and reliable travel suitcase is very important whether you are going on a business trip, vacation, or home to visit your parents. You could carry fragile and sensitive items you’d like to arrive in one piece.
For peace of mind, we’ll evaluate and compare polypropylene, polycarbonate, and ABS luggage to find the best fit for your needs. Ensure it fits all your items and is safe even under rigorous conditions.
Comparison Table
Here is a quick comparison of the key differences between these materials:
| Material | Pros | Cons |
|---|---|---|
| Polycarbonate | Strong, Durable | Expensive, Heavier |
| Polypropylene | Light, Affordable, Durable | Less Durable, UV Degradation |
| ABS | Affordable, Lightweight | Less Durable, Less Strong |
Whether you are traveling domestically or internationally, there are several guidelines that you must always adhere to at the airport. The size and weight of your luggage are the top two that you should pay close attention to unless you don’t mind paying a huge additional fee.
The right polycarbonate, polypropylene, or ABS luggage for your needs will help ensure your checked suitcase is of the right weight. Since you don’t need a collection of suitcases at home, take your time to find the right fit. So, what’s the best material between polypropylene, polycarbonate, and ABS luggage?
Detailed Material Analysis
Let’s examine the differences between these hard-side luggage materials used in making travel suitcases in more detail.
Polycarbonate Luggage
Most major brands offer polycarbonate luggage options in their catalogs. These are travel suitcases made of thermoplastic polymers that contain carbonate groups in their chemical structures. Polycarbonate materials are easy to work with, mold, and thermoformed into different products, including hard-side luggage material and bulletproof glass.
- Very reliable
- Durable, and can withstand any abuse
- Very expensive
- Heavier and may be harder to transport
Polypropylene Luggage
Polypropylene luggage is made from thermoplastic polymers through the chain-growth polymerization of mono polymers. They lie between polycarbonate plastic and ABS luggage, giving them the best of both worlds. They are more durable than ABS and lighter than polycarbonate luggage.
- Temperature and chemical-resistant
- Affordable
- Lightest (even lighter than aluminum luggage)
- Good for frequent use
- Less durable than polycarbonate luggage
- Susceptible to UV degradation
ABS Luggage
ABS plastic luggage is made of a thermoplastic called ABS (acrylonitrile-butadiene-styrene). This is a cheap hard material, which makes it popular among cheaper hard-side luggage.
- Affordable
- Pliable and flexible
- Lightweight
- Less durable
- Not as reliable
Direct Comparisons
Comparing the different types of travel luggage on the market is a key component of making a more informed decision about which suitcase to invest in. Since your carry-on will be safe with you most of the time, below is a comparison of the three main types of checked traveling luggage.
Polypropylene vs Polycarbonate Luggage
The main difference between polypropylene and polycarbonate luggage is the heaviness of the material used in manufacturing polycarbonate bags, which makes them much heavier than polypropylene suitcases.
This thick material makes the suitcases more durable and increases their resistance to impact and scratches. It also makes polycarbonate bags much more expensive than their counterparts’ polypropylene bags.
On the other hand, polypropylene luggage is more lightweight and affordable as compared to polycarbonate suitcases.
Polycarbonate vs ABS Luggage
A key difference between polycarbonate luggage and ABS luggage is their flexibility. Polycarbonate bags also have a higher impact resistance than ABS suitcases.
ABS bags are more affordable in terms of pricing, but they lose the race regarding usage and durability. If you are not a frequent traveler, these ABS bags will serve you well—albeit for a shorter period—if you are not a frequent traveler.
Though not as strong or durable as polycarbonate luggage, some blends or ABS luggage can serve well—especially if used with care and without abuse.
Polypropylene vs ABS Luggage
ABS (5500 psi) has a higher tensile strength than polypropylene (4000 psi), making it stronger and harder. However, this doesn’t translate to more durable luggage. The rigidity of ABS makes it more prone to cracks, thus decreasing its lifespan.
This makes flexibility the major difference between polypropylene and ABS luggage. Flexibility means more resistance to impact and cracks, translating into longer durability. Investing in a flexible travel suitcase will save you money in the long run.

Buying Guide (Factors to Consider)
With all the different types and brands of travel suitcases on the market, you must find one that perfectly suits your needs before you “add to your cart.” I have compiled a shortlist of factors to consider when choosing a suitable travel suitcase. Let’s go check them out!
Size
The first thing you should consider is the size of the luggage. This will depend on the amount of luggage and your destination; if you are going on a business trip, you might not need as much space as if you were going on vacation.
Whether you opt for polypropylene, polycarbonate, or ABS luggage, they all come in different sizes. So you don’t have to compromise on the luggage size you want.
Durability
The most durable luggage for travel is polycarbonate. It’s heavier-duty plastic and sturdy material resistant to scratches and falls.
Airport luggage handlers aren’t always gentle when moving traveling bags; if you have something fragile, a polycarbonate suitcase might be the way to go.
It’s closely followed by polypropylene luggage, designed to be chemical and temperature-resistant. Minor falls and overzealous baggage handlers won’t damage your luggage, though the effects will become visible over time.
ABS luggage is the least durable due to its light material. However, some ABS blends are on the market if you want to invest in a stronger one.
Weight
Polycarbonate luggage is the heaviest due to the sturdy and strong plastic material used in its manufacturing. Heavy materials mean that anything you pack in this luggage will be safe and secure no matter how it’s handled at the airport.
ABS is second in weight. It’s a great option if you are looking for something light but don’t plan on using it often. Polypropylene plastic is the lightest suitcase on the market. It’s made of a thermoplastic polymer that’s quite strong but lightweight, making a polypropylene suitcase even lighter than aluminum suitcases.
Cost
The next thing to consider is the price. The price of a travel suitcase will vary depending on the size, color, materials, brand, and features. The most affordable of the three is the ABS suitcase, made from cheaper material; it is great for someone who doesn’t travel a lot and is looking for a low price tag.
Polypropylene and Polycarbonate suitcases are more moderately priced and can last long, saving you money in the long run.
Some features and add-ons that might make two suitcases of the same size and from the same brand vary, including wheels and easy locks.
Design
Design differences between ABS, polypropylene, and polycarbonate luggage are another important factor to consider.
This includes subtle differences such as TSA locks, extra-thick materials, expansion zippers, and multidirectional wheels. Though they can all be used to carry your traveling products, designers add these features to make them more convenient.
With the information provided here, you are now in a much better position to discern the best luggage for travel between abs, polypropylene, or polycarbonate travel luggage.
However, remember that what works for one person might not work for you. The resources below can even help you better decide which type of travel luggage to buy.
