Stretch wraps come in different types with varying load capacities and strengths; every type offers specific properties essential to the application it is meant for.
Thus, choosing the right thickness of the gauge could make a world of difference. That’s because the amount of weight or force that a stretch wrap can withstand before it fails is determined by the thickness of the stretch film.
For example, a 60-gauge stretch wrap can typically withstand a load of up to 1,800 lbs. If your load exceeds 1,800 lbs., you will need a stretch wrap with a higher gauge.
From the examples above, it is clear that choosing the correct gauge for the task is crucial and way more efficient.
Selecting the Right Stretch Wrap Gauge Thickness
To choose the right gauge of stretch film for a given job, you need to know what each gauge is used for. The following is a guide to choosing the right gauge for your job.
A stretch wrap of 37-gauge is produced by stretching the 80-gauge film and is so thin that it is ideal for light loads of up to 800 lbs. Being a stretched form of an 80-gauge film, it’s different from other gauges of stretch wraps.
If you need to bundle together two light and uniform objects, a 37-gauge stretch wrap will be a great choice to accomplish the task.
The 47-gauge stretch is produced with the use of a different kind of resin, offering a tighter and stiffer film whose stretch capacity is lower.
It is also referred to as a hybrid or equivalent stretch wrap.
It has the strength and retention power of a 60-gauge stretch film, which makes it capable of easily withstanding loads of up to 1800 lbs. approximately.
You can use it to bundle heavier and uniform objects, but it is not ideal for objects with sharp corners or edges.
Just like the 47-gauge stretch film, 60-gauge film is also capable of handling loads of up to 1800 lbs.
If it is measured with a micrometre, the reading will be 60 microns exactly, which proves it to be a true-gauged stretch film.
Also, as far as its applications are concerned, you can ideally use it for small boxes, lighter and smaller objects, etc.
Some companies use it in place of tape as well.
A stretch wrap thickness of 63-gauge offers the capability of withstanding loads of up to 2,200 lbs.
Though this gauge thickness is not much higher than the previously mentioned 60-gauge stretch film, it offers better resistance when it comes to tearing and puncturing.
A 70-gauge film is suitable for bearing loads of approx. 2200–2400 lbs. and it offers slightly stronger holding strength when compared with the 60-gauge film.
Stretch wraps of 70-gauge thickness are generally used for bundling multiple cylindrical items.
It is the most commonly used gauge in all types of stretch wraps.
It offers good versatility, which makes it suitable for a diverse range of applications.
Moreover, as far as the load-bearing capacity is concerned, the 80-gauge film is considered to be ideal for loads of up to 2200–2400 lbs.
The 90-gauge stretch film is 10 microns thicker compared with the 80-gauge film.
It comes with noticeably better stretch and strength as well.
You can consider using it for wrapping and bundling angle iron, firewood, and various other types of heavy objects.
A film of 90-gauge thickness can easily handle loads of up to 2600 lbs.
If you are in need of bundling heavier products and boxes, the 100-gauge stretch film is what you need to fulfil the requirement.
You can use it for medium-heavy items and medium-heavy boxes.
This thickness of the stretch wrap is ideal for withstanding loads of up to 2800–3000 lbs. approximately.
A 115-gauge film is suitable for loads of up to 3,000 lbs. or even more, and you can use it for smaller heavy objects.
Generally, it is used for bundling together sets of heavy objects.
150-gauge is the thickest gauge available for stretch wraps and is considered suitable for securing sharp items and irregularly shaped objects.
In addition to this, if you are in need of securing taller loads, this one is no doubt ideal to fulfil the requirement.
The most popular types and applications of stretch wraps are shown in this article.
As you can see, stretch wrap is available in a wide range of different thicknesses.
