A cooling pack comprises at least one coolant carrier (10) for keeping coolant held thereon and a container (11) adapted to enclose the coolant carrier (10). The coolant carrier (10) consists of liquid absorbent substrate (12) and liquid absorbent polymer particles (13). The container (11) has at least a pair of flat layers opposed to each other which are adapted to introduce liquid into the container (11). The cooling pack can provide beneficial features such as to avoid exudation of liquid absorbent polymer particles (13), to introduce liquid into the container (11) in a short period of time, and to obtain non-sticking of the container (11) refrigerated condition.

A cooling pack comprising at least one coolant carrier obtained by dispersing and fixing liquid absorbent polymer particles integrally on liquid absorbent fibrous substrate with substantially uniform distribution and successively forming said substrate into a sheet or a mat, and a flat bag-shape container having at least first and second flat layers opposed to each other to enclose said coolant carrier, wherein said first flat layer of said container is made of liquid-permeable fibrous nonwoven fabric, said nonwoven fabric carrying on the inside thereof at least along the central area except the transversely opposite side areas a liquid-impermeable plastic sheet or film so as to cover at least a major portion of said coolant carrier to which said liquid-impermeable plastic sheet or film is opposed; and wherein said second flat layer is made of a liquid-impermeable plastic sheet or film.
