Backpack Material Craft

Because backpacks are used in special environments, higher requirements are placed on the materials and craftsmanship of backpacks. All stress-bearing positions of the backpack are sewn three times with back stitches to make the stress-bearing positions durable. The buckle and other parts of the backpack can be anti-freeze, anti-smashing and deformation at 120 degrees Celsius without damage. The outer material of the backpack mainly includes 420D Oxford nylon, 1000D nylon, 600D or 1000Dpolyester (polyester), or 1000D CORDURA and other materials. The 1000D material has a high density and is very wear-resistant, making it suitable for outdoor use. CORDURA is a well-known high-grade wear-resistant nylon roving fabric developed by DuPont Company of the United States. The material is far more abrasion resistant than typical nylon or polyester and is lightweight. More than 90% of the backpacks of famous brands in the world use this prestigious nylon material. These materials can withstand 0.5m~2m of water pressure to keep the contents of the bag dry. Some materials also have anti-tear function, once punctured, the breach will not tear open and expand.
