Which material is better for lightweight travel bags: TPU or PVC

When selecting materials for lightweight travel bags, TPU generally outperforms PVC in five key areas:

1. Greater Flexibility: TPU is highly elastic and can bend and fold without damage, making it ideal for compact packing. PVC is more rigid and prone to cracking in cold conditions.

2. Superior Durability: TPU resists wear, tearing, and weather-related damage, making it more suitable for frequent use. PVC degrades faster over time.

3. Lighter Weight: TPU offers strength without bulk, which is crucial for comfortable long-term carrying. PVC tends to be heavier.

4. More Reliable Waterproofing: TPU retains its waterproof properties longer, while PVC can lose integrity with use.

5. Better Environmental Performance: TPU is more recyclable, and some versions are biodegradable. PVC contains chlorine and poses more environmental concerns.

For travelers seeking comfort, portability, and sustainability, TPU is clearly the better option. PVC only makes sense for one-off, low-budget uses.
