ABS vs Polypropylene Luggage — Which Should You Choose?

When you're shopping for a new hard-shell suitcase, you'll quickly come across two materials: ABS and Polypropylene (PP). Both are popular choices for hard-shell luggage, but they have distinct differences that can affect your decision. Here's everything you need to know.

What is ABS Luggage?

ABS stands for Acrylonitrile Butadiene Styrene — a thermoplastic polymer that has been used in luggage manufacturing for decades. It's the more traditional of the two materials and is widely used across budget to mid-range suitcases.

Pros of ABS

• Affordable — ABS is generally less expensive to produce, making ABS suitcases more budget-friendly
• Lightweight — ABS cases tend to be light, helping you maximise your baggage allowance
• Impact resistant — handles knocks and bumps well under normal travel conditions
• Wide colour range — ABS takes colour and finish well, offering a broad choice of styles

Cons of ABS

• Less flexible — ABS can crack under extreme pressure rather than flexing and recovering
• Less heat resistant — can warp in very high temperatures (e.g., in hot cargo holds)
• Heavier than PP — when compared directly to polypropylene at the same size

What is Polypropylene (PP) Luggage?

Polypropylene is a newer, more advanced material that has become increasingly popular in premium and mid-range luggage. You'll often see it described as "PP" or "hard shell polypropylene" on product listings.

Pros of Polypropylene

• Exceptionally lightweight — PP is one of the lightest hard-shell materials available, ideal for maximising your weight allowance
• Flexible and resilient — PP flexes under pressure and springs back to its original shape, making it far more resistant to cracking
• More durable long-term — better suited to frequent travellers who put their luggage through regular wear and tear
• Heat resistant — handles temperature extremes better than ABS

Cons of Polypropylene

• Slightly more expensive — the superior material comes at a modest price premium
• Fewer budget options — PP tends to feature in mid-range and premium cases rather than entry-level

Which Should You Choose?

Choose ABS if:

• You travel occasionally and want a reliable, affordable suitcase
• You're looking for a great value cabin bag or short-trip case
• Budget is your primary consideration

Choose Polypropylene if:

• You travel frequently and need a suitcase that can take a beating
• You want the lightest possible case to maximise your baggage allowance
• You're investing in luggage for the long term
