A schoolbag is a bag made of cloth, leather, or similar materials. Students use it to carry textbooks and stationery. Based on changing consumer aesthetic tastes, schoolbags have evolved into a more lightweight option – the luggage bag. Luggage bags now come in a wider variety of materials, including genuine leather, PU, polyester, canvas, and cotton/linen. Luggage bags closely follow fashion trends. At the same time, in an era that increasingly values individuality, various styles such as minimalist, retro, and cartoonish designs cater to the needs of fashion-conscious individuals who want to express their individuality.
Based on the material, backpacks are further divided into canvas bags, Oxford cloth bags, and nylon bags. The main advantage of backpacks is their portability, freeing up the hands and providing convenience for outings.
