Lightweight and tough. PP (polypropylene) is a semi crystalline polymer thermoplastic material with strong impact resistance and flexibility, as well as corrosion resistance. It has a density of 0.9 and is lighter than water, making the PP suitcase both lightweight and tough.

Strong and sturdy. PP suitcase has good mechanical load-bearing capacity, stable material, and outstanding waterproof performance.

Heat and cold resistant. The PP trolley box adopts a four layer co extrusion process, which has good heat and cold resistance, and can maintain stable performance even in extreme weather conditions.

Durable and wear-resistant. PP material is wear-resistant, less prone to scratches and wear, and less prone to deformation and discoloration after long-term use.
