Question 1

What is net stretch?

Accepted Answer

Net stretch is the percentage a film is elongated beyond its unstretched length. A value of 150 percent means the film was stretched 1.5 times beyond its uncorrected length.

Question 2

Why is film weight entered in ounces?

Accepted Answer

Film applied to a single load is small, so ounces give a more precise figure. Roll weight stays in pounds, and the calculator converts between the two.

Question 3

How is cost per load calculated?

Accepted Answer

Cost per load divides the roll cost by roll weight to get a cost per pound, converts the film applied from ounces to pounds, then multiplies the two.
