Stretch Film Calculator

Formula

To calculate the Stretch Film Length (\(SFL\)):

\[ SFL = \frac{L \times W \times H}{SFW} \]

Where:

\(SFL\) is the length in feet of stretch film needed
\(L\) is the length of the package (ft)
\(W\) is the width of the package (ft)
\(H\) is the height of the package (ft)
\(SFW\) is the width of the stretch film (ft)

What is Stretch Film?

Stretch film is a film of clear plastic that is most often used when wrapping packages for shipping. It is designed to stretch and cling tightly to the items being wrapped, providing a secure and protective covering.

Example Calculation 1

Let's assume the following values:

Length of Package (\(L\)) = 5 ft
Width of Package (\(W\)) = 3 ft
Height of Package (\(H\)) = 2 ft
Width of Stretch Film (\(SFW\)) = 1 ft

Using the formula:

\[ SFL = \frac{5 \times 3 \times 2}{1} = 30 \text{ feet} \]

The stretch film length needed is 30 feet.

Example Calculation 2

Let's assume the following values:

Length of Package (\(L\)) = 4 ft
Width of Package (\(W\)) = 4 ft
Height of Package (\(H\)) = 4 ft
Width of Stretch Film (\(SFW\)) = 2 ft

Using the formula:

\[ SFL = \frac{4 \times 4 \times 4}{2} = 32 \text{ feet} \]

The stretch film length needed is 32 feet.
