Each material has its own advantages and disadvantages. This mainly depends on personal hobbies. I will introduce it to you, and then you will choose from it.
ABS resin is a commonly used engineering plastic with excellent performance, high hardness, good compression resistance, excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties, and has easy processing, The product has the characteristics of stable dimension and good surface gloss.
PC resin is polycarbonate resin, which is usually the material of space cups, barreled drinking water buckets and discs. It is also a commonly used engineering plastic with excellent performance and excellent crack resistance;
Comparison of the above two mainstream materials: ABS is usually slightly thicker than PC because of its crack resistance that is slightly worse than that of PC.And the specific gravity of ABS resin is also larger than that of PC resin, so the ABS trolley case is heavier than the PC trolley case of the same size. In comparison, ABS has better compression resistance, and PC has better crack resistance. Of course, PC are cheaper. The specific choice is based on your needs.
Personally think that in addition to the material, the following points of the luggage are also very important.
1. Universal wheel:
Many brand bags are equipped with universal wheels, which can be pushed and translated. Compared to two-wheel bags that can only be pulled on one side, the use of universal wheels is relatively more convenient. During the trial, you should know whether the luggage walking wheel rotates flexibly, and you should try to buy a pulley with bearings.
2. Internal compartment:
Is there a clear layering inside the luggage, such as wet and dry layering, folding clothes bag, hanging zipper bag, file storage, laptop bag and other areas, users choose products with obvious intervals according to their personal needs.
3. Tie rod:
Tie rods are just as important as pulleys. If the tie rods are disconnected during the journey, it is really enough. At present, the major brands of tie rods are mainly made of lightweight and durable materials such as aluminum alloy, and some products also have a 360° rotating handle design.
4. Password lock:
There are various forms of combination locks, in addition to fixed combination locks, to ensure the safety of the items in the bag. In addition, users purchase external security locks and can choose TSA luggage code locks. Airport security personnel can use special tools to open this type of code lock without damaging the lock.
Mainstream bags are mainly 18 inches, 20 inches, 22 inches, 24 inches, 26 inches, 28 inches and 30 inches. The Civil Aviation Administration of China stipulates that the weight of individual checked baggage cannot exceed 50 kg per piece, and the volume cannot exceed 40×60×100 cm. Baggage exceeding the above requirements must be checked in advance by the airline before it can be checked. The weight of self-care luggage shall not exceed 10 kg, and the volume of each piece shall not exceed 20×40×55 cm.
