I love to use heat sealed balloons in my designs. They add such a wow factor and creative twist you can’t get on the high street. A lot of balloon business owners, though, tell me they struggle to get consistent results with heat sealing. In this blog, we will look at what is heat sealing, why you should definitely be doing it in your business and I will show you a neat trick (check out the video below) I learned to ensure you get consistent results every time you heat seal! I am also going to share some creative inspiration from amazing balloon artists that will get you loving heat-sealed designs!

What balloons need heat sealing?

Microfoils (also known as non-valved balloons) are the smaller foil balloons which have no automatic valve. They are airfilled only as they do not have enough gas capacity to float if filled with helium. Because they have no valve the air will escape if not heat sealed to create a permanent seal on the balloon.

Microfoils come in a variety of shapes and sizes. Plain ones come in star, heart and circle – 4” or 9”- and are in a variety of colours. Character and printed foils come in 9“ and 14” and the odd other size. There are a huge variety to choose from covering the majority of celebrations as well as popular characters. Many of the microfoils compliment the designs of the larger balloons allowing you to create gorgeous designs around a theme.

Why it’s great to use balloons that require heat sealing.

Heat sealed balloons add such wow factor to your designs. But what are the other benefits of adding heat sealed balloons to your designs?

You can charge more – All the designs showcased on this blog post have increased the perceived valued value by adding in a couple of additional heat sealed elements. For only a few pence per balloon and a couple of minutes of your time, you can charge way more!

It differentiates you from the competition – Adding in heat sealed balloons to your designs will quickly elevate your portfolio and customers love them! When they see what you can offer and how creative and unique your designs are they will be queuing at your door and willing to pay a little extra for something different!
It allows you to theme balloon designs without breaching copyright laws – So many customers want balloons with Disney and other themes to them. Using heat-sealed balloons allows you to purchase licenced balloons and create amazing themed designs without getting into strife with your vinyl cutter! I also believe it’s quicker and more effective to inflate and heat-seal a microfoil than design, cut and weed vinyl then apply to balloons!

You can add them to any design – they are so versatile and can be used in grand arches, garlands etc but also in smaller numbers, gift and tabletop designs… even candy cups!

They are a cost-effective way to grow your portfolio – Most wholesalers sell microfoils singularly and a lot of them are under £1! You can quickly grow your portfolio without having to invest in large volumes of more expensive balloons.

What equipment do you need to heat seal balloons?

Heat sealing requires a way of heating the foil so it adheres to itself and forms a seal. Over the years I have heard people say they use hair straighteners and all sorts of other devices. It’s my experience that to get consistent results you are best to invest in an inexpensive heat sealer. Heat sealers can be purchased from most balloon wholesalers as well as Amazon and othe places. They generally come in two sizes: 8 inch or 12 inch. I prefer the 12” as it gives more to work with.

The heat sealer contains a wire which is covered by a non stick sleeve. You place the foil on top of the surface of the heat sealer and then press down to seal. A light will come on whilst heating is taking place and go off when you should release.

Number 1 tip for heat sealing

It can be tricky (especially when first starting) to get a good secure seal. Watch this video where I share a tip I learned to get a wide consistent seal EVERY single time!

What setting should you set your heat sealer on?

One of the questions I regularly get is what heat setting should the heat sealer be set on. This is tricky to answer as every heat sealer can be slightly different! Having used many at different events and training over the years I would generally say 2-3 works well but it is a case of trying yours out and finding a setting that works well. Once you have it set it should work fine for years. If you do find that your heat sealer isn’t working as expected you may need to change the wire element – it can become worn over time. Most heat dealers come with replacement wires and replacement sleeves. Replacement sleeves may be required if foils become overheated and the colour from the balloon transfers on to them as they may then mark future balloons. Sometimes you can remove the colour by pressing greaseproof paper but stubborn stains may need the cover to be changed.
