New Design Zipper High Quality Luggage Travel Hard Shell Trolley Case Low Waterproof Portable Safety Carry On Suitcase
The classification of suitcases is not only the same as the sealing method, but also the suitcase material is different.
The zipper suitcase is generally made of cloth (canvas, oxford, nylon), leather (leather, artificial leather) and plastic (PC, ABS) suitcases, which are generally softer.
The materials generally used for the aluminum frame suitcase body are plastic (PC, ABS) and magnesium aluminum alloy.
Zipper suitcase
Advantages
Light in mass
Compared with metal materials, cloth surfaces, leather surfaces and plastics, the overall mass is much lighter. After all, the suitcase has to follow people. Although it has wheels, it is inevitable to carry it up and down the stairs. The soft suitcase will save a lot of effort.
Pack a lot
Because it is soft, it is flexible, and the space utilization is higher, so it can be installed more. The things we carry in our suitcases have various shapes and are not particularly regular, and it is inevitable that they will be squeezed when they are full. It’s flexible enough to hold up.
More impact resistant
The toughness of the soft suitcase is stronger, it can rebound after being impacted and deformed, and the drop resistance and wear resistance will be better.
Disadvantages
Poor water and stain resistance
The cloth suitcase is a woven fabric, which is not waterproof, and there are also cloths with waterproof function, but there is still a gap compared with plastic suitcasees and metal suitcasees. Another point is that the woven fabric is easy to get dirty, it is very inconvenient to clean, and the leather surface is more delicate.
Poor fashion
It is not easy to make a cloth suitcase fashionable in appearance. The leather case is better than the cloth case. It can be made very textured, but it is very afraid of scratching. Plastic suitcasees and metal suitcasees have much more play space, and can make many unique appearances. The play space of color and texture is much larger than that of soft suitcasees.
Weak protection of internal items
The soft case is flexible, but it is more prone to internal injuries. If you need to carry valuable instruments such as cameras and computers, there is a risk of breaking.
Aluminum frame suitcase
Advantages
Well-protected interior space
The strength of the hard case is higher than that of the soft case. The earliest hard cases were aluminum, which was lighter than other metals. But aluminum is soft and easily corroded, so magnesium was added later to improve strength and corrosion resistance.
Later, with the maturity of plastic technology, there began to be high-strength plastics such as PC, and slowly there was a hard case combination of PC + aluminum frame.
Shape texture
mentioned earlier. Whether it is a PC aluminum frame or a magnesium-aluminum alloy suitcase, it will be more textured and fashionable than the cloth suitcase.
Disadvantages
Heavy
This was just said. Because it is an aluminum frame suitcase, the material used is aluminum, and the weight is naturally heavier.
Limited space
This is not difficult to understand, the aluminum frame suitcase is too much to close the suitcase.
No rebound and scratch resistance after impact
The soft case will recover after a few falls, but if the hard case hits a hole, a small bump can be knocked back with a small hammer from the inside. If the aluminum frame is smashed and deformed, the suitcase will not close.
