measuring
for film
Measuring your box to determine the needed film size can be confusing.
You need to consider HOW you want your box to be wrapped. For the neatest
wraps, you’ll want the folded edges to occur on the shorter or smaller sides. These
sides where the folds will occur are the “
ends
.” The distance between these two
“
ends
” is the “
span
.” Start by finding the measurement of your
span
. This is the
distance between the two
ends
.

The film needs to lay across the
span
to the edge and then fold over more than
half way down the
ends
. If the film doesn’t go more than half way down, there
won’t be any overlap to accomodate the seal. Let’s start this step by measuring
the depth of one
end
.

amount of overlap

Now you’ll need to determine how much overlap you want for the ends. If you
want .25” of overlap, add .25” to the equation. For .5” of overlap, add .5” to the
equation and so forth. For boxes with long, shallow ends, we recommend adding
the full depth again.
For a 3”x3”x3” box with .5” desired overlap, the formula would be:

.5
= 6.5” roll
For a 5”x1”x3” box with .75” desired overlap, the formula would be:

= 6.75” roll
