What is the best material for the suitcase

The luggage is made of ABS, PP, PC, and aluminum magnesium alloy materials, which are relatively good.
1. ABS material, lightweight, flexible and rigid, capable of withstanding large impact forces; High surface hardness and good chemical resistance; Easy to clean, can be washed with water or wet wipes.
2. PP material, resistant to high-strength impact, corrosion and wear, easy to clean.
3. PC material, resistant to extrusion, corrosion, and impact. However, the hardness is relatively insufficient, and it is usually combined with ABS material to achieve the effect of learning from each other's strengths and weaknesses, which has an advantage in cost-effectiveness.
4. Aluminum magnesium alloy, with high strength, strong compression resistance, corrosion resistance, beautiful and elegant appearance, can be used for a typical box for five to ten years.
