Enter the roll length (ft), the roll width (in), and the film gauge into the Stretch Film Weight Calculator. The calculator will evaluate the Stretch Film Weight. 

Stretch Film Weight Formula

The following formula is used to calculate the Stretch Film Weight. 

SFW = L * W * (G/250,000)

Variables:

  • SFW is the Stretch Film Weight (lbs)
  • L is the roll length (ft) 
  • W is the roll width (in) 
  • G is the film gauge 

How to Calculate Stretch Film Weight?

The following two example problems outline the steps and information needed to calculate the Stretch Film Weight.

Example Problem #1

  1. First, determine the roll length (ft).
    • The roll length (ft) is calculated to be : 120.
  2. Next, determine the roll width (in). 
    • The roll width (in) is measured to be: 30.
  3. Next, determine the film gauge. 
    • The film gauge is found to be: 150.
  4. Finally, calculate the Stretch Film Weight using the formula above: 

SFW = L * W * (G/250,000)

The values provided above are inserted into the equation below and computed.

SFW = 120 * 30 * (150/250,000) = 2.16 (lbs)

Example Problem #2

The variables required for this problem are provided below:

roll length (ft) = 60

roll width (in) = 30

film gauge = 1000

Test your knowledge and check your answer with the calculator.

SFW = L * W * (G/250,000) = (lbs)
