Let's check out a label that says 80 gauge 20" x 6,000'. Using the formula 20 x 6000 x .8 x .0004 = 38.4.
Your roll should have 38.4 pounds of stretch film on it. This weight does not include the core. Now to
double check. Weigh a full roll of your film with the core included. Let's say you come up with a weight of
40.6 pounds. Now find an empty core after the film has been used and weigh the core. If everything is to
the letter, your core should weigh 2.2 pounds.

Let's be fair and recognize that there can be some variation in the weight of a roll of film due to the gauge
having some fluctuation during the manufacturing process, or small variances due to a different film
density. But if you weigh your roll of film and it weighs 37.5 pounds with the core in it, and the formula
shows it should weigh 38.4 pounds without the core, then you either have a short footage roll, or a thinner
gauge than the label is showing. You might have your supplier double check a roll for you to see if it is
labeled correctly as I have seen a few cases were the wrong label was put on film at the plant by accident.

and you should know how to read them.
