Glass base material packing method

Abstract

A method of packing a glass base material (10, 20, 30), which is a base material of an optical fiber comprising packing the glass base material (10, 20, 30) into a cylindrical container (16, 26, 36). The packing has: putting the glass base material (10, 20, 30) into a plastic bag (12, 22, 32); and packing the glass base material (10, 20, 30), which is put into the plastic bag (12, 22, 32), into the cylindrical container (16, 26, 36). The packing further has: wrapping the glass base material (10, 20, 30), which is put into the plastic bag (12, 22, 32), with air packing material (14, 24, 34), which contains air inside; and packing the glass base material (10, 20, 30) wrapped with the air packing material (14, 24, 34) into the cylindrical container (16, 26, 36).
