Material classification of three types of suitcases

A beautiful and practical suitcase can definitely add a lot of points to your trip, when you buy a suitcase, the first thing you should consider is the material of the suitcase, because it determines the appearance and practicality of the suitcase. At present, the more common suitcases on the market are mainly divided into three categories, namely hard shell boxes, soft boxes and leather cases. Each of these types has a different representative material.

ABS resin is one of the five synthetic resins, its impact resistance, heat resistance, low temperature resistance, chemical resistance and excellent electrical properties, but also has the characteristics of easy processing, product size stability, good surface gloss, easy to paint, coloring, can also be surface sputtering metal, electroplating, welding, hot pressing and bonding and other secondary processing, widely used in machinery, automobiles, electronic appliances, instrumentation, textile and construction and other industrial fields, is a wide range of thermoplastic engineering plastics.

Advantages of ABS suitcase: relatively hard, not easy to be pressed and deformed, high shell strength, not affected by water, inorganic salts, alkali and a variety of acids, not easy to break, can effectively protect the contents of the contents. The appearance of ABS is opaque ivory granules, and its products can be colored and have high gloss.

Disadvantages of ABS material suitcase: high price, large weight, inconvenient to carry, no small one, basically large. In addition, the price is much higher than Oxford cloth and artificial leather.

Polypropylene (PP plastic) is another excellent resin variety developed after nylon, which is a high-density, side-chain-free, high-crystallization linear polymer with excellent comprehensive properties. When not colored, it is white translucent and waxy. The transparency is also better than polyethylene and harder than polyethylene.

PC material is actually one of the so-called engineering plastics, as a widely used material around the world. It has excellent electrical insulation, elongation, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance; It also has the advantages of self-extinguishing, flame retardant, non-toxic and colorable

At present, the materials of soft boxes are mainly nylon, oxford cloth or non-woven materials. Although these fabrics do not look as fashionable as hard shells, they are also very durable, and it is not as brittle as some PVC materials, which is easy to go wrong in consignment.

Suitcases made of cloth combined with EVA have become very popular in the past decade. The revolution of soft boxes embarked on a new generation of development system, which can make the cloth of the soft box three-dimensional, can shape a variety of shapes and curves, and can save manufacturing wages, accelerate the production process, and then cooperate with the use of honeycomb panels, a new generation of suitcases was born, it feels like a hard shell box, but there is no weight of the hard shell box, the shell is more varied, and the amplification function can be added, equipped with a pull rod, and the design of multiple pulleys at the bottom makes the user more convenient and convenient, allowing shoppers, let overseas shopping travelers, No more suitcases.

It should be noted that this imitation leather product similar to PU leather has no advantages at all except for more patterns in color appearance.
