Hard Shell Luggage Material Comparison

Suitcases are divided into hard-shell suitcases and soft-shell suitcases. Today we will talk about the materials of hard-shell suitcases.

PP material - Strong and chemical resistant

Advantages: strong and crashworthy, high hardness, resistance to organic solvents and acid and alkali corrosion, high-temperature resistance

Disadvantages: bulky

Compared with other plastics, PP material is bulkier, but it is resistant to various chemical substances and high temperatures. In addition, the crashworthiness is better, and the protection of the luggage is enhanced.

ABS material - Scratch-resistant, the most affordable price

Advantages: drop-resistant and crash-resistant, high hardness, wear-resistant and scratch-resistant, non-slip, cheap

Disadvantages: Insufficient toughness, easy to break, easy to brittle and crack in cold climates

100% pure PC material - The best plastic

Advantages: compression resistance, shock resistance, impact resistance, cold and heat resistance, light box body, not easy to break, colorful

Disadvantages: not scratch-resistant, expensive

PC+ABS material - Highest CP value, mainstream on the market

Advantages: impact resistance, high hardness, good elasticity, good resistance to cold and heat, light box, colorful

Disadvantages: not scratch-resistant, slightly higher price

Plastic boxes are lighter than aluminum-magnesium alloys, stronger than shell boxes, and easier to repair. At present, the best plastic material for suitcases on the market is pure PC material, but unfortunately, the price is too expensive; while ABS material is highly hardness, wear-resistant, scratch-resistant, and cheap, the disadvantage is that it lacks toughness and is easy to break.

The PC+ABS material that combines the two is just the middle value. The crash resistance, elasticity, and price are all in the middle, and the CP value is high. It is suitable for friends who like a variety of colors, beauty, and practicality.

Aluminum-magnesium alloy material - Strong the first choice

Advantages: higher strength, better shock resistance, impact resistance, and fall resistance, excellent protection effect, better moisture resistance

Disadvantages: Heavy empty; expensive; hard to repair if suitcase warped or cracked
