Referring to Figures 1, 2, 3, 4A, 4B, 5 and 6, the present invention is a space bag having a hot-melt joint, comprising: an outer bag unit 10 having a plurality of The outer wall sheet 11 is used to surround a receiving space 12.

An inner bag unit 20 is disposed in the accommodating space 12, and the inner bag unit 20 has two layers of a first plastic film 21 and a first woven plastic cloth layer 22, and the first woven plastic cloth layer 22 is a warp and weft. The interwoven woven structure, the first woven plastic layer 22 is interposed between the two first plastic films 21; and the inner bag unit 20 has an inner surface portion 20A and four peripheral corner portions 20B.

A plurality of reinforcing units 30 each having two layers of a second plastic film 31 and a second woven plastic layer 32, wherein the second woven plastic layer 32 is a warp and weft interlaced structure, the second weaving The plastic cloth layer 32 is interposed between the two second plastic films 31. Each of the reinforcing units 30 is coupled to the inner surface portion 20A and faces the corresponding peripheral corner portion 20B to constitute a structure for reinforcing the inner bag unit 20.

A plurality of hot-melt joints M are respectively located at a joint position of each of the reinforcing units 30 and the inner surface portion 20A, and each of the heat-melting joints M is the reinforcing unit 30 and the inner surface portion 20A. The structure after curing by hot melt bonding.

In practice, the first woven plastic cloth layer 22 is composed of a plurality of strips of plastic material, and has a warp and weft interlaced structure.

Each of the reinforcing units 30 has a main piece portion 30A and two side edges 30B. The side edge portions 30B are connected to the inner surface portion 20A, and the main piece portion 30A is fixed to the corresponding peripheral corner portion 20B.
