The back pad structure 100 can be mainly used for the manufacture of a backpack or a ridge backpack, which can be directly contacted with the back of the human body or placed in a backpack or a ridge backpack near one side of the human body for protection. The user's back has a good ventilation and heat dissipation.

Please also refer to the air-permeable mesh 10 as shown in FIG. 1A and FIG. 1B, which is a layer of the structure of the back pad structure 100, which is in direct contact with the back of the human body or close to the back of the human body when in use. The breathable mesh 10 can be a three layer mesh to achieve good breathability.

As shown in FIGS. 1A and 1B, the thermoplastic buffer layer 20 has a first surface 21 and a second surface 22, and the thermoplastic buffer layer 20 is combined with the second surface 22 and the breathable mesh 10 for thermoplastic molding. . The thickness of the thermoplastic buffer layer 20 can be selected according to the needs of the application. For example, in the case where the load of the backpack such as mountain climbing or long-distance travel is heavy, increasing the thickness of the thermoplastic buffer layer 20 can increase the comfort of using the backpack and reduce fatigue. In general, the thickness of the thermoplastic buffer layer 20 in combination with the thermoplastic of the breathable mesh 10 is more often selected to be greater than the thickness of the breathable mesh 10.

The thermoplastic buffer layer 20 as shown in FIGS. 1A and 1B may be formed of an ethylene vinyl acetate polymer (EVA) material. EVA material has the advantages of light weight, softness and elasticity. It is very suitable for combination with the breathable mesh 10 thermoplastic to become the back pad structure 100 for making backpacks.
