1. ABS material
The main material of the hard box is made, and most of the trolley cases made by it are hot vacuum forming. The trolley case has a more delicate interior and a change in the surface of the case, which is more resistant to impact than the soft case, but the weight is heavier because of the presence of the frame. However, it is solid and it protects the clothes from wrinkles and fragile. Try to fill it up as much as possible, press it and close it. ABS is basically a very durable material.
2. PP material
The main material of the hard box is made, and the trolley case made by it is mostly formed by heating and shrinking. The inside and outside of the box body belong to the same color system and have no inner lining. The development cost of PP material is relatively expensive, the product price is also high, spare parts are special equipment, can not be modified, so only a very professional brand and manufacturers have the ability to produce, it is characterized by impact resistance, waterproof.
The main material for hard case making, it has excellent electrical insulation, elongation, dimensional stability and chemical resistance. Intensity, heat resistance and cold resistance are also satisfactory, but their hardness is relatively insufficient. It is usually combined with ABS material to achieve the effect of lengthening and complementing each other. At the same time, ABS+PC material has advantages in cost performance.
The main material of hard box making is also the most familiar material for everyone. Because it is metal, it is very malleable, and it is durable, wear-resistant and impact-resistant. Generally, the box can be used for five years and ten years. The shape is one-piece, but also has a combination of molding, the appearance is very beautiful, but compared with other material trolley cases, the weight and price should be a lot more.
The main material for soft box making, strictly speaking, PE material is not soft enough, it is lighter than ABS material but more impact resistant. People often combine it with cloth or leather to form a soft box. After the combination, the trolley case has both the safety of the hard box and the softness of the soft box. The disadvantage is that if the sewing thread is cracked, the trolley case will be scrapped. Therefore, we must pay attention to the rationality of space use.
The main material of soft box making, EVA material combined with cloth or leather is a revolutionary trend in recent years. This trolley case looks like a hard box, but the quality is particularly light, the cabinet panel changes a lot, and the function design is expanded. Sexually strong, able to adapt to the use of most consumers, has been quite popular in recent years.
7.Nylon (PA) Oxford cloth, polyester, leather, PU material
Nylon, oxford and leather are the main materials for soft box making. They are more wear-resistant and have a beautiful appearance. However, they are economical and practical. They have not been used for more than ten years. Leather has a good texture and can greatly enhance the aesthetics of the product. Pay attention to routine maintenance when using. As an artificial leather, PU has the same advantages as leather, and the price advantage is very obvious.
