Inhibitor parcel and method for preserving electronic devices or electronic parts

摘要

Disclosed are an inhibitor parcel comprising (a) a composition comprising 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 unwoven fabric onto the other side of the base sheet, said permeable diffusing-parcelling material (b) having an oxygen permeability of 10<4> to 10<6> ml/m<2>.Atm.Day and a (water vapor permeability/oxygen permeability) ratio of 0.02 [H2O mg.Atm/O2 ml] or above at 25 DEG C at a relative humidity of 50% and said composition (a) being parcelled by said permeable diffusing-parcelling material (b) and an inhibitor parcel for use in electronic devices and electronic parts which comprises said inhibitor parcel and a method for preserving electronic devices and electronic parts using said inhibitor parcel.
