How To Check The Material And Durability Of PC Luggage?

Material inspection:

Identify PC material: PC luggage is usually made of polycarbonate plastic, which is sturdy, durable, lightweight, and has characteristics such as drop resistance, impact resistance, waterproofing, and wear resistance. Check if the luggage is labeled as PC material or pure PC material, which usually means higher durability and better protection performance.
Comparing different PC materials: Common PC materials on the market include pure PC, PC+ABS alloy, etc. Pure PC material performs better in terms of wear resistance and aging resistance, while PC+ABS alloy, although durable, may be more prone to aging problems in long-term use or harsh environments.
Durability testing:
Impact resistance test: completed by simulating real-life scenarios of falling and heavy pressure to verify the stability and recovery ability of the box structure.
Wheel wear resistance test: requires the wheel to continuously roll on different textures of ground to evaluate its wear resistance and service life.
Durability test of pull rod: By frequently pulling and retracting the pull rod, its flexibility and strength can be tested.
Zipper and buckle durability test: as they directly affect the safety of items inside the box.
Physical performance testing:
Oscillatory impact performance: Under specified load conditions, conduct an oscillatory impact test on the backpack to check for cracks in the body, deformation, fracture, or damage to all components.
Suture strength test: Check the suture strength of the backpack seam to ensure that it is not easy to open or tear.
Inspection of attachments and accessories:
Corrosion resistance of hardware accessories: Check the corrosion resistance of hardware accessories to ensure that they are not easily rusted or damaged under long-term use.
Box lock test: For PC luggage with a box lock, check the locking performance and safety of the box lock.
