Abstract
A manufacturing method for a moisture permeable device suitable for use in a refrigerator where the device includes a corresponding first surface (110) and second surface (111); at least parts of the first surface (110) and the second surface (111) of the moisture permeable device define a hollow cavity (301); through-holes are provided at regions of the first surface (110) and the second surface (111) of the moisture permeable device defining the cavity (301); and regenerated cellulose is accommodated in the cavity (301) includes the steps of pouring a regenerated cellulose slurry with a tackifier added thereto into the cavity (301) to form a moisture permeable film, thus allowing omission of an assembling procedure and a non-woven support.
