- Mar 24, 2020-

In recent years, the frequency of backpack use is increasing. Different backpacks have different materials and production processes.

Let ’s take a look at the materials and processes of the backpack.

Because backpacks are used in special environments, higher requirements are placed on the materials and processes of some backpacks. Some backpacks are made by high-frequency machine hot pressing to be more waterproof. All backpacks are sewn three times with stitches and back stitches to make the positions strong and durable.

It can be protected against frost, smashing and deformation for 120 seconds without damage.

The outer material of the backpack is mainly 420D Oxford nylon, 1000D nylon, 600D or 1000D polyester (polyester), or 1000D CORDURA and other materials.

1000D material has high density and wear resistance, which is very suitable for field use. CORDURA is a very famous high-grade wear-resistant nylon roving fabric developed by DuPont of the United States. The abrasion resistance of this material is far more than ordinary nylon or polyester, and it is lightweight.

More than 90% of the world's famous brand backpacks use this prestigious nylon material. These materials can withstand a water pressure of 0.5m ~ 2m to keep the objects inside the bag dry. Some materials also have an anti-tear function. Once punctured, the opening will not tear apart and expand.
