[0010] In order to facilitate taking and placing the packaging bag, as a preferred self-sealing bag type blood bag storage packaging bag of the present invention, the outer walls of the two heat-insulating parts are both provided with handles.

[0011] In order to facilitate folding and heat exchange, as a preferred self-sealing blood bag storage packaging bag of the present invention, the folding portion is made of polyethylene material.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model can seal the two heat-insulating parts by arranging a second self-sealing clip chain, thereby isolating the coolant in the inner bag from the outside world before being placed in the refrigerator, preventing heat exchange, and extending the effective cooling time of the coolant; after being placed in the refrigerator, the second self-sealing clip chain between the two heat-insulating parts is opened, so that the blood bag in the packaging bag can exchange heat with the cold air in the refrigerator through the folding part, thereby improving the use effect.
