20″ VS 30″ Film

Make sure that you understand the difference between 20 and 30!

We all know that there is a significant difference between 20 and 30.  What 20 vs 30 is really like…

It does not matter if you are talking years or stretch film, the difference can be astounding.  Thankfully Highlight Industries has the ability to help determine if 20” or 30″ film is right for you.

Using the Highlight Stretch tools App you can determine if the cost is worth the speed increase  Lets walk through the exercise.

Use these parameters:

Your pallet dimensions are 60” tall, 48” long, and 40” wide.

We would like to wrap up to the top, do 2 top wraps, then wrap down again (so in the “up only or up and down” input, enter 2) completing the cycle by with 2 bottom wraps. 3” overlap will be a good number to use in our example.

Press calculate and you will find that in this application we would recommend 20″ film as it a 9% savings compared to 30” film and will only require 4 revolutions more of the turntable.

20" vs 30" film

Since most semi-automatic turntables will rotate a maximum of 12 revolutions per minute, your speed increase is 20 seconds of wrapping time using 30” film per pallet.  20″ film will wrap in  75 seconds compared to 30” film wrapping in  55 seconds.

Why is there a savings on film?

When a photo eye senses the top of the pallet, it stops it upward travel.  Since the top of the film carriage (regardless of film width) stops at the same position, 30” film will add 10” of film more than 20” film to the body of the load.  This will then be repeated at the bottom wraps position.

So the next time you are looking at 20” film vs. 30” film do a time study (as you would always complete) but also take into account that there is more duplication and determine if the speed is worth the financial cost.
