The waterproof and scratch-resistant properties of a trolley case are one of the important features of a high-quality suitcase.
Aluminum alloy is a lightweight and strong metal that is often used to make the outer shell and part of the structure of a suitcase. It has excellent corrosion resistance and can resist erosion from water and humid environments to a certain extent. The surface of a trolley case is usually specially treated, such as anodizing or spraying a protective layer, to enhance its waterproof performance.
The waterproof performance of a trolley case is mainly reflected in the sealing of its outer shell and the waterproofness of the material. High-quality trolley cases usually use tight stitching and waterproof zippers to ensure that the internal space of the case is isolated from the outside world and prevent moisture from penetrating. In addition, aluminum alloy itself has a low water absorption rate and is not easily deformed or damaged by moisture. Some high-end models also use waterproof strips in the gaps of the case to further enhance the waterproof effect.
Aluminum alloy has a high hardness, so it has good scratch resistance. Compared with plastic or leather suitcases, the surface of a trolley case is less likely to be scratched or worn. Especially when encountering hard or sharp objects during travel, the aluminum alloy shell can effectively protect the items in the box from damage.
The scratch resistance of the trolley case is also affected by its surface treatment process. The surface of the anodized aluminum alloy will form a dense aluminum oxide film, which not only improves the corrosion resistance of the material, but also significantly enhances its scratch resistance. In addition, some manufacturers will spray a wear-resistant layer on the surface of the aluminum alloy or use other hardening treatment technologies to further improve the scratch resistance.
In actual use, the trolley case has excellent waterproof and scratch resistance. In rainy days or humid environments, the trolley case can effectively protect the items in the box from moisture. At the same time, during the consignment or handling process, even if it encounters scratches from hard or sharp objects, the aluminum alloy shell can maintain its integrity and reduce the risk of damage to the items in the box.
In order to maintain the waterproof and scratch resistance of the trolley case, regular maintenance and care are recommended. You can use a soft dry cloth to wipe the surface of the case to remove dust and stains. Avoid using a hard brush or abrasive cleaners to avoid scratching the surface. In addition, be careful to avoid prolonged exposure to sunlight or high temperature during use to prevent the material from aging or deformation.
The waterproof and scratch-resistant performance of the trolley case is excellent, which can meet the needs of most travelers. Its sturdy shell and tight sealing design effectively protect the items in the box from moisture and scratches. However, it is also necessary to pay attention to regular maintenance and care to maintain its optimal performance. When choosing a trolley case, you can choose different models and brands according to your personal needs and budget to get a better use experience.
