ABSTRACT:
An object of the present invention is to provide a glass fiber package where a glass fiber aggregate which contains alkali-containing glass wool fiber of a very small diameter having an average fiber size of 5 μm or less or, particularly, less than 1 μm and containing 5% or more by weight or, particularly, 10% or more by weight of alkali metal oxide components is packed in a compressed state to give a form which is able to be handled as a freight, and in which, fiber breakage (lowering in the fiber length) and fiber adhesion caused by compression packing is hardly resulted even upon a long-term storage whereby the properties inherent to the glass fiber immediately after its manufacture is apt to be maintained; to provide a method for packing the glass fiber; and to provide a glass fiber product using the same.A glass fiber package of the present invention includes a glass fiber aggregate which contains alkali-containing glass wool fiber having an average fiber size of 5 μm or less and containing 5% or more by weight of alkali metal oxide components is packed in a compressed state so as to give a form which is able to be handled as a freight where the bulk density is 80 to 135 kg/m3.
