Shrink Wrap Film Gauges Explained

Friday, July 1st, 2011

Shrink Wrap Film Gauges If you’re an electrician, or have worked with electrical wiring, you probably know that the lower the gauge number, the thicker the wire. For example, 16-gauge wire is actually significantly thinner than 10-gauge wire. This almost goes against common reasoning as higher numbers typically represent bigger or thicker. So is this the case with the gauge of shrink wrap film?

Shrink wrap film is commonly available in 60, 75 and 100 gauge thicknesses. As you might understand, many people wonder if 60 or 100 gauge film is the thickest. Shrink wrap film gauges, contrary to electrical wire gauges, are actually thicker as the number goes up. One-hundred gauge film is in fact thicker than 60 gauge shrink wrap film.

Hopefully this helps clarify some of the confusion out there. While we have established how shrink wrap gauges work, you should be aware that there are two primary different types of shrink wrap film. These are:

  1. PVC Shrink Wrap Film
  2. Polyolefin Shrink Wrap Film

While both PVC and Polyolefin shrink film gauges are literally the same in thickness, you should be aware that 75 gauge PVC and 75 gauge Polyolefin act very differently.

Shrink Wrap FilmOne of the biggest reasons people go with thicker PVC film is to prevent tearing or breaking of the film. This is because PVC film has a more brittle quality to it than Polyolefin film.

While people increase the film gauge with Polyolefin to help increase the packaging strength as well, Polyolefin film has an elastic-like stretchy quality to it. For this reason, 60 gauge Polyolefin film, while thinner, has just as good an integrity quality as 75 gauge PVC film. Simply put, you don’t need as thick a gauge of Polyolefin film to get the same results as 75 gauge PVC film.

Best Gauge Of Shrink Wrap Film

Best Gauge Of Shrink Wrap FilmI have customers ask me at least a couple of times a week which gauge of shrink wrap film is the best to use. I always answer that question with my own question, “what will you be shrink wrapping?” Answers to this question will help you determine the optimal gauge of shrink film you will need for your packaging projects.

There are two primary types of shrink wrap film. These are PVC film and Polyolefin (Poly) shrink wrap film. Both types of film are made from high quality materials. Both films have similar shrinking temperatures and can be used universally on most shrink wrap machines.  Both of these films are usually available in a centerfold roll format.

PVC film is old school, having been around for some time. PVC shrink wrap film has a harder texture to it and is commonly used for packaging DVDs, CDs, boxes and other material.

Polyolefin film is a little newer than PVC. While it can still be used to package DVDs, boxes and other retail goods, it is also food safe. Poly film also has a more stretchy quality to it than PVC film.

The gauge of shrink wrap defines the thickness of the film. The higher the number, the thicker the film. Many people think that they need a thicker film simply because thicker has to be better, right? I tell most people that they will be fine with thinner gauge film

Thicker gauge film is best used for bundling multiple products together, where the chance of the film bursting or tearing open is higher.

PVC film typically comes in 75 gauge and 100 gauge thicknesses. The 75 gauge continues to be the most popular thickness.

Polyolefin film usually comes in 60 gauge, 75 gauge and 100 gauge thicknesses. Since Polyolefin film is stretchier than PVC film (and tears less easily), you can usually get away with the 60 gauge film without any problems.
