Suitcases are divided into hard-shell suitcases and soft-shell suitcases. Today we will talk about the materials of hard-shell suitcases.
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.
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
Advantages: compression resistance, shock resistance, impact resistance, cold and heat resistance, light box body, not easy to break, colorful
Disadvantages: not scratch-resistant, expensive
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.
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
