In addition to wallets, backpacks, messenger bags and handbags, there are also suitcases in the bags that people use everyday. Luggage, as a large object and large-capacity luggage necessary for people's daily life, is not only convenient and practical, but also very easy and comfortable in the process of use. But what are the materials of the suitcase? Let's take a look at the advantages of luggage made of five materials. I. PP polypropylene PP is a semi-crystalline polymer thermoplastic material, which itself has extremely strong impact resistance, flexibility, corrosion resistance, etc, so PP is a good material for making bags. Second, PC polycarbonate PC is an amorphous thermoplastic resin with very good comprehensive properties. Its price is not only low, but also it has good stability, corrosion resistance, high temperature resistance and cold resistance. Therefore, PC is the best choice for plastic bags. 3. EVA vinyl ester EVA is a common copolymer material in daily life, and it has many advantages, such as softness, pressure resistance, shock resistance, skid resistance, etc, it is a good material choice for making bags. 4. PVC vinyl PVC is a non-crystalline copolymer material. PVC has strong resistance to oxidant, reductant and strong acid, and its manufacturing cost is relatively low, which is very suitable for the choice of luggage materials. Five, ABS propylene--Butadiene-- Phenyldiene ABS is a thermoplastic polymer material with high strength and toughness, which not only has heat resistance and chemical resistance of acrylonitrile, toughness and impact resistance of butadiene, there is also the stiffness and processability of styrene, which is also very suitable for making luggage. The biggest advantage and commonality of the luggage made of the five materials is that the waterproof performance is extremely strong. Therefore, if the luggage is made, it should be combined with its own needs, and then compared with the advantages or disadvantages of various luggage materials, finally, choose the best material as the material for making bags.
