With the continuous improvement of people's living standards and consumption levels, various bags have become indispensable accessories in people's lives. People demand that bag products not only be enhanced in practicality, but also in their decorative aspects. According to changes in consumer tastes, bag materials have become more diverse. At the same time, in an increasingly individualistic era, various styles such as simplicity, retro, and cartoon styles cater to the needs of fashion-conscious people to express their individuality. The styles of bags have also expanded from traditional business bags, school bags, travel bags, wallets, small handbags, etc. So, what are some commonly used materials for bags?

1. PVC Leather 
PVC leather is made by coating fabric with PVC resin, plasticizers, stabilizers and other auxiliaries to form a paste, or by laminating another layer of PVC film, then processed through a certain process. The product has high strength, is easy to process, and has low cost. It can be used for various bags, seat covers, linings, sundries, etc. However, it has poor oil resistance and high temperature resistance, and poor low temperature flexibility and feel.

2. PU Synthetic Leather 
PU synthetic leather is used to replace PVC artificial leather, and its price is higher than that of PVC artificial leather. In terms of chemical structure, it is closer to leather fabrics. It does not use plasticizers to achieve softness, so it will not become hard or brittle, and it has the advantages of rich colors and various patterns, and the price is cheaper than leather fabrics, so it is welcomed by consumers.

The difference between PVC artificial leather and PU synthetic leather can be distinguished by the method of gasoline immersion. The method is to use a small piece of fabric, place it in gasoline for half an hour, and then take it out. If it is PVC artificial leather, it will become hard and brittle; if it is PU synthetic leather, it will not become hard and brittle.

3. Nylon 
With the acceleration of the miniaturization of automobiles, the high performance of electronic and electrical equipment, and the lightweight of machinery equipment, the demand for nylon will be higher and greater. Nylon has high mechanical strength, good toughness, and high tensile and compressive strength. Nylon has a strong ability to absorb impact and stress vibrations. Its impact strength is much higher than that of general plastics and is superior to acetal resin. Nylon has a low coefficient of friction, smooth surface, strong alkali resistance and corrosion resistance, so it can be used as packaging material for fuels and lubricants.

4. Oxford Cloth 
Oxford cloth, also known as Oxford fabric, is a functional and versatile fabric. The main varieties on the market include: grid, full elastic, nylon, and raised grid. Oxford cloth has excellent waterproof performance, good wear resistance, durability, and long service life. The fabric characteristics of Oxford cloth are very suitable for various bags.

5. Denim 
Denim is a relatively thick color-woven twill cotton fabric. The warp yarns are dark in color, generally indigo blue, and the weft yarns are light in color, generally light gray or boiled white yarns. There are also those made of imitation suede, corduroy, velveteen and other fabrics. Denim is mainly made of cotton, and it has good moisture permeability and air permeability. The woven denim is dense, full, crisp, and has a rugged style.

6. Canvas 
Canvas is generally made of cotton or hemp as raw materials, and is a relatively thick fabric. It can be roughly divided into coarse canvas and fine canvas. Canvas has many excellent characteristics, which makes the use of canvas extremely wide, such as the common canvas shoes, canvas bags, tablecloths, and tablecloths are all made of canvas.
