Abstract

The method of packaging coils uses a tear-resistant packaging tube having openings at either end. The tear-resistant packaging tube is made from at least one layer of material. The coil is generally cylindrical and defines a length, a circumference, an inside diameter, and an opening with an inner periphery. The coil is placed inside of the tube so that there is excess circumferential tube material extending from a first end of the coil. The excess circumferential material of the tube is then inserted through the opening at the center of the coil and drawn through the coil to the second end. The edges of the tube which extend from the second end of the coil are then folded back around the outside of the coil and sealed to secure the tube on the roll.
