All About Using A Heat Gun for Shrink Film

Shrink wrapping is crucial for companies that sell products, as shrink film is the primary way that products can, not just stay safe from outside contaminants, but also stay bundled if you are sealing multiple products at once. If you need a way to wrap products using shrink film, there are multiple ways in which you can do so. They all would involve having to heat the shrink film so that it, of course, shrinks, in order for the film to tighten, conform to the packaging, and create a strong bond so that the film won’t come off unless torn off intentionally.

The primary way to heat shrink film is with a heat sealer, which is a machine that allows you to conform the film to a product one at a time. There are many different types of sealers, but they all typically cost hundreds of dollars. These are ideal if you have a product that you wish to sell in large quantities. If you are looking for a more economical way to heat shrink film, you can use a heat gun which can work with any film from shrink film manufacturers.

A heat gun is ideal if you are only looking to heat wrap one object at a time, and it doesn’t even need to be used if you have products to sell. If you are storing or transporting goods on a pallet, a heat gun can allow you to heat the whole load manually so that everything stays secured and bundled together. Heat guns can be used to heat shrink film on things like candles, cookies, and other homemade goods.

How to Shrink Film with A Heat Gun?

Shrink film is affordable, coming in multiple types such as polyolefin, PVC, and polyethylene. These three types of film are the most common and are used in multiple industries. Some types of film work better than others, depending on the product you want to use. Shrink film comes in bags, flat rolls, centerfold rolls, and tubing.

Next, you need to determine the measurements you need depending on the type of shrink film you buy. There is a formula for each, as seen below:

For Bags

Circumference + 10% / 2 = Required width of bag.

Length + depth + 2 = Required length of bag.

For Centerfold Film

Width + depth + 2 = Required width of roll.

For Tubing

Circumference + 10% / 2 = Required width of tubing.

After confirming your measurements, you can prepare your heat gun for sealing. Place the product inside your shrink film with the measurements you’ve come up with. Close the ends of the shrink film together. Turn on your heat gun and apply heat to these ends so that they bond. Make sure to leave half of an inch of space between the shrink film and the package so that you don’t accidentally burn the packaging. If the film “balloons” or fills with air rather than shrink, you might need to cut a small hole through the film so that the air can escape.

Heat guns should be straightforward to use, as well as easy, so long as you properly follow the instructions and avoid any trouble. Heat guns can also be used alongside a heat sealer, and might be necessary for unique and irregular packages that require shrink film.

Summary

Heat guns are an alternative to heat sealers, and are a manual and more affordable option for heating shrink film to products. Heat guns can work with any type of film, and there is a process and technique for being able to heat film in a proper manner.
