Abstract
Disclosed are an inhibitor parcel including (a) a composition including an unsaturated fatty acid compound as its main ingredient and (b) a permeable diffusing-parcelling material prepared by laminating and bonding an oxygen-permeable resin layer onto one side of a base sheet made of a fibrous material and an adhesive or onto one adhesive-coating side of a base sheet made of a fibrous material, then laminating and bonding thereonto an oxygen-permeable resin layer and laminating and bonding a porous film of low softening point resin or a low softening point nonwoven fabric onto the other side of the base sheet, the permeable diffusing-parcelling material (b) having an oxygen permeability of 10.sup.4 to 10.sup.6 ml/m.sup.2. Atm. Day and a (water vapor permeability/oxygen permeability) ratio of 0.02 [H.sub.2 O mg.Atm/O.sub.2 ml] or above at 25.degree. C. at a relative humidity of 50% and the composition (a) being parcelled by the permeable diffusing-parcelling material (b) and an inhibitor parcel for use in electronic devices and electronic parts which includes the inhibitor parcel and a method for preserving electronic devices and electronic parts using the inhibitor parcel.
