Suitcases are a fairly large investment in terms of your trip planning and budgeting, ranging from $200-$2000 for a reputable brand, they certainly all have different offerings designed for different traveler. It’s common too that you don’t buy the suitcase just for one trip; you need to align your suitcase with the type of travel you do most often to get the most value out of the one bag.

Hard luggage is generally divided into 6 materials:


CURV® is a patented technology from Germany. For the first time, it is applied to suitcases. The material is very light and the surface has ripple-like textures. Because it is quite lightweight, it is very popular with consumers.

Advantages: low density, good fusion, design research shows that this material can save 50% of weight. 100% polypropylene, 100% polypropylene composite material replaces fiber reinforced materials, which has significant environmental advantages. It does not contain any glass fiber at all, it is gentle and easy to handle, non-irritating, and the surface is smooth and wear-resistant, no additional coating is needed. It is a thermoformed product with low cost. Withstands high impact strength and provides maximum protection. It is resistant to corrosion and abrasion, is easy to clean and does not require additional surface protection.

二.PC material-polycarbonate

The PC material can be said to be a luxury upgraded version of ABS.

Advantages: High temperature and cold resistance from + 125 ° C to -100 ° C. The box shell is flexible to pressure and can bend. Once the pressure disappears, the box will automatically return to its original state. It can be said that it is a more perfect suitcase material.

 三.Synthetic resin (ABS material)

ABS resin is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. , Coloring, and can also be used for secondary processing such as surface spray metal, electroplating, welding, hot pressing and bonding. It is widely used in industrial fields such as machinery, automobiles, electronic appliances, instruments and meters, textile and construction. Wide range of thermoplastic engineering plastics.

ABS resin is currently the largest output and most widely used polymer. It unifies the various properties of PS, SAN, and BS organically, and has excellent mechanical properties of toughness, hardness, and rigidity. ABS is a terpolymer of acrylonitrile, butadiene, and styrene. A represents acrylonitrile, B represents butadiene, and S represents styrene.

Advantages: It is not affected by water, inorganic salts, alkalis and various acids, but it is soluble in ketones, aldehydes and chlorinated hydrocarbons. Stress cracking will occur due to erosion by glacial acetic acid and vegetable oil. ABS has poor weather resistance and is prone to degradation under the action of ultraviolet light; after half a year outdoors, the impact strength is reduced by half. It has good electrical insulation and is almost independent of temperature, humidity and frequency. It can be used in most environments. Excellent impact strength, can be used at extremely low temperatures; ABS has excellent abrasion resistance, good dimensional stability, and oil resistance, and can be used for bearings under medium loads and speeds. The appearance of ABS is opaque and ivory colored pellets, and its products can be colored colorful and have high gloss.

四.Four.PP material

PP plastic is polypropylene, English name: Polypropylene. Its density is small, and its strength, stiffness, hardness and heat resistance are good.

Advantages: moisture-proof and pressure-proof. Low transparency, low gloss, low rigidity, but stronger impact strength.

五.ABS + PC material

This material is basically well understood. It belongs to the intermediate gear between ABS and PC. The impact resistance, hardness, strength and toughness are in between, which is better than ABS and worse than pure PC.

Advantages: high gloss, good toughness, good heat resistance. Can be electroplated, can spray paint, can PVD, many optional processes.

六.aluminum magnesium alloy material

Magnesium aluminum alloy is an alloy containing magnesium metal in aluminum alloy.

Advantages: It has the same strength and hardness as steel, but it is much lighter than steel and close to plastic. It is not easy to be deformed by compression, and the shell has high strength, and it is not affected by water, inorganic salts, alkalis and various acids. It is not easy to break and can effectively protect the contents.

Hard Suitcases Major Benefits

  • Lightweight and strong construction. The strength to weight ratio is generally better on the latest ultra-lightweight hard suitcases.

  • Better security – the hard shell reduces theft through case slitting (or anyone adding something to external pockets)

  • Maximum packing space, due to the thin plastic shell construction you get maximum packing space inside as space is not given over to folds of fabric and lining.

  • Protection for your belongings, the hard shells are very durable and resilient, if your case is dropped it offers better impact resistance and therefore protects fragile items inside better.
