How to Measure For Shrink Wrap Bags and Shrink Wrap Tubing (With Illustrations)

A couple of months ago we wrote a blog post about how to measure for shrink wrap. The post is a detailed post about how to measure for each one of our shrink wrap products. There are different methods for measuring for shrink wrap bags shrink wrap tubing, and centerfold shrink wrap.

The problem with our post was we did not offer any illustrations to help explain the methods we were describing. This post we want to illustrate measuring a circumference. We can help determine the size of shrink wrap film you need by having length and width dimensions, but we prefer a circumference measurement when sizing for shrink wrap bags and shrink wrap tubing.

Measuring the circumference of an object is commonly associated with round objects.

It is much easier when measuring for shrink wrap bags and shrink wrap tubing to measure the circumference for all objects. As stated above, it is possible to fit proper shrink wrap with length and width dimensions, but circumference measurements are much easier. Below are a couple of illustrations of measuring circumference for non-round objects.

The illustration for the book is not completely accurate. The tape measure should not be at an angle, it should be straight across. Once the circumference for the object is measured, add 10% to the measurement and divide by two and that is the width of shrink bag or shrink tubing you need. Then for shrink wrap bags, measure the length and that will be the length of bag you will need.

  3. Hi,
    I am use to using pvc shrink wrap for 18650 batteries and 26650 batteries…and I’ve been trying to find the size PVC shrink wrap that I would need… I only have maybe 2 inches of this PVC wrap left. It came in a flat roll it is Hollow in the center so that you can shrink the item( in my case containers and batterries) with a ruler laying flat the tube PVC shrink wrap measures about two and a half inches(and as I said before it is Hollow so it would be 2 and 1/2 inches on both sides but I donnot know what size MM-wise to order
