Referring to fig. 1 to 3, the present invention provides a food packaging bag 100 including a wall portion and an inner space 6 formed by the wall portion. The wall portions comprise a first wall portion 1, a second wall portion 2 and a bottom wall 5. The first wall part 1 and the second wall part 2 are fixed together to form a first sealing edge 3 and a second sealing edge 4. In use, an article is placed in the internal space 6 from an opening (not shown), and then the opening is sealed, thereby achieving the effect of packaging the article.

The wall part comprises an inner layer, an outer layer and a middle layer arranged between the inner layer and the outer layer, the middle layer is an anti-collision layer, and the middle layer comprises a plurality of elastic tubes filled with media. When the food packaging bag 100 is impacted, the elastic tube filled with the medium can play a technical role in protecting the articles in the food packaging bag from being damaged. The details are as follows.

Referring to fig. 2 and 3, the first wall part 1 comprises a first inner layer 13, a first outer layer 11 and a first intermediate layer 12 interposed between the first inner layer 13 and the first outer layer 11. The first intermediate layer 12 includes a first layer 121 adjacent the first outer layer 11 and a second layer 122 adjacent the inner layer 13. The elastic tube is formed by combining a first layer 121 and a second layer 122. The second layer 122 includes a connection portion fixed to the first layer 121 and an arc portion connected to the connection portion and protruding toward the inner layer, and the arc portion is combined with the first layer 121 to form the elastic tube 123.
