Detailed description of the invention

Referring to drawings and Examples, this utility model is described in detail.

As shown in Figure 1 to Figure 3, cold-storage packaging material of the present utility model, including two cold-storage layers, two cold-storage layer laid out in parallel and mutually separating; Difference outside adventitia 1 and inner side adventitia 2 in above-mentioned cold-storage layer, outside outside adventitia and inner side, intermembranous hot-sealing line 3 welding formed by hot pressing, constitutes the fluid reservoir 4 of multiple mutual separation between hot-sealing line; Above-mentioned each fluid reservoir is correspondingly arranged inlet 5, and inlet is connected with fluid reservoir by feed pathway 6. In fluid reservoir, fill agent for storage of coldness by inlet and feed pathway in use, cold-storage packaging material can be made to become the object continuing to send cold, thus keeping it to surround or covering the temperature of article.

Feed pathway 6 is half-duplex channel, will not reflux from feed pathway or leakage, to keep the volume of agent for storage of coldness in fluid reservoir after making agent for storage of coldness enter fluid reservoir.
