Several reasons contribute to the importance of durability in luggage. First, travelers often encounter rough handling by airline staff and various travel conditions.

Durability refers to the ability of a product to resist wear and deterioration over time. In luggage, it often encompasses materials like polycarbonate, ballistic nylon, or high-denier polyester, which are known for their strength and resilience.
Detailed mechanisms add to the durability of luggage. For instance, reinforced stitching prevents seams from ripping, while high-quality zippers can withstand repeated use without failure.

-
Polycarbonate:
Polycarbonate is a highly durable plastic known for its lightweight properties. Premium luggage made from polycarbonate can withstand significant impacts without cracking. According to a study by the Journal of Materials Science, polycarbonate is resistant to UV light, which helps prevent fading from sun exposure during travel. Brands like Samsonite have leveraged polycarbonate to create lightweight, robust suitcases that are easier to handle in transit. -
