The trolley case is made of PP or PC. Which of the two materials is better? Of course, I recommend the PC material. I think that many domestic big-name luggage models on the market are basically made of PC. The PC material luggage is more portable. , This is also more important, no one wants to carry a bulky suitcase, and the PC material is resistant to wear and tear.

　　I have some understanding of this aspect, I will not post the picture, just say it briefly. Pure PC is the most expensive, the material is a bit heavy and heavier, but the cabinet is very soft, that is, the legendary is very tough. Can be used by the car The ones that can be restored by direct rolling are generally mirror models. Pure ABS is very cheap, and the cabinet made is very light and hard, but very.

　　The suitcase made of ABS+PC is made of ABS box body and PC film. This material box combines the advantages of ABS and PC and avoids the shortcomings of both, that is, it improves the heat resistance and stretch of abs plastic luggage. Strength reduced the PC melt viscosity and improved.

　　I'm pulling you, you're pulling the suitcase, let's go far away together, okay? Everything is available, only the suitcase is owed. However, when we choose the suitcase, we will encounter many problems. For example, what size to buy, What kind of material to choose, how to choose the shape of the tie rod, how many wheel configurations are good... etc.
