Document Summary
Out of all of the metals on our planet, two are the most used in the packaging industry. They are used for different things, but their chemical properties allow us to manipulate them and mold them in to packages that we can use in our day to day lives. Iron is converted to steel through a series of steps: Steel is coated to be used in can manufacture. Base box is a term used to measure the area of metal. It"s a similar concept to basis weight for paper and paperboards, and it indicated the plating sizes of the metals. 1 base box = 31,360 sq. in. Once the base box is determined, there are specifications for the weight of the metal per base box. This weight per base box is called the plating: plating weights specified as lbs. /base box: higher plate number = thicker plating. Ex: tin plated steel designated as 20 plate has 0. 10/0. 10 lbs/base box tin.
