Introduction to luggage
一、Material: PC VS ABS VS FULL ALUMINUM
The material of the suitcase directly determines its weight, toughness and protective ability.
1. PC material (polycarbonate)
Features: Currently the mainstream choice for high-end soft and hard luggage .
Excellent toughness: The greatest advantage of PC is its flexibility. When subjected to heavy pressure or impact, it will not break but will undergo elastic deformation and return to its original shape.
Light weight: Under the same size, PC are usually about 1.5-2 kilograms lighter than all-aluminum .
Disadvantages: The surface of pure PC is relatively prone to scratches (although scratches also represent travel marks)
2. ABS material (Acrylonitrile-Butadiene-Styrene copolymer)
Features: Common material used for entry-level hard cases.
High hardness but brittle: The ABS material is extremely hard, has good rigidity, feels solid when touched, and is usually much cheaper than PC.
Disadvantages: Lack of toughness. Due to its brittle nature, when subjected to violent transportation or heavy pressure, ABS are more prone to cracking or even developing direct holes. For long-term and frequent business trips, the lifespan of ABS is often shorter than that of pure PC
3. Fully Aluminum Magnesium Alloy
Features: Representative of industrial aesthetics and ultimate protection.
Sturdiness and appearance level: The full-aluminum luggage boasts an unparalleled metallic texture and minimalist industrial design, with extremely high recognizability. It has the strongest compressive strength. Even if you jump on it a few times, it will basically not deform
Disadvantages:
Heavy weight: Even the empty box is much heavier than the PC box.
Easy to leave marks: Once subjected to severe impact, the metal surface will leave indelible depressions that cannot be repaired.
Poor cost-effectiveness: The manufacturing process is complex, and the price is usually 2 to 4 times that of a standard PC case of the same size.
Conclusion:
1.If you are looking for ultimate durability, portability and a reasonable budget, a pure PC is the best choice.
2.If the budget is limited and the use is only once or twice a year (such as during the Spring Festival when people return home), made of ABS or a mixture of PC and ABS will be sufficient.
- If you have no financial constraints, value a business-like appearance, and prefer point-to-point chauffeur-driven transportation, the all-aluminum box can serve as a symbol of your status and taste.
二、HOW TO CHOOSE THE SIZE?
(The size selection mainly depends on the number of days of travel and whether you are checking in luggage)
20 inch
Specification: 34cm × 50cm × 20cm
Applicable scenarios: Short business trips or travels lasting 1 to 3 days.
Features: No need for luggage check-in, simply bring it onto the plane.
24inch
Specifications: 42cm × 68cm × 26cm.
Applicable scenarios: 3-7 day domestic tours or seasonal trips.
Feature: This is the most common size for household use. It can accommodate sufficient laundry items without being too large to be easily moved.
24-inch - 26-inch
Specification: 42cm x 68cm x 26cm for 24-inch size.
Applicable scenarios: 3-7 day domestic tours or seasonal trips.
Feature: This is the most common size for household use. It can accommodate sufficient laundry items without being too large to be easily moved.
- inch - 30-inch
Specification: 47cm x 78cm x 30cm.
Applicable scenarios: Long-distance trips lasting more than 7 days, studying abroad, overseas shopping, or family outings.
Notes:
Weight limit: Once fully packed, it is very likely to exceed the airline's 20-23 kilogram free checked baggage allowance, and the overweight fee is relatively high.
Portability: Once filled, it is extremely heavy and may not fit in the trunk of some older cars.
Final tip:
Apart from the material and size, when making a purchase, don't forget to pay attention to the wheels and the handlebars.
Try to choose double-row universal silent wheels (smooth and quiet) and all-aluminum handlebars (with low wobble and less prone to breakage).
I hope this article can help you find the ideal "travel companion"!
