Helium Balloons

Party balloons are something so many of us grew up enjoying as children. As such, these classic party decorations are often a fun way of teasing the ‘inner child’ out of your guests. Bring life to the party when you decorate your next event with Koch & Co’s extensive range of helium balloons. Explore our professional-grade inflatables, easy-to-use helium tanks, and range of balloon accessories that can boost the elegance and longevity of your display.
 
If your upcoming event requires you to follow a specific theme or colour palette, we have the tools you need to meet the brief. We stock large foil letter and number balloons for a sweet 16th, engagement party love heart helium balloons, latex balloons in pearlescent, metallic, matte, and traditional fashion finishes, as well as big bubble balloons, that with a little DIY can be stuffed with gift items like roses and soft toys.

In Need Of Party Decor For Your Special Event?

If you’re shopping for party supplies and want to check out our extensive range of wholesale helium party balloons and accessories, come have a look in person at our Koch & Co Superstore in Auburn, NSW. If click and collect is more to your style, we offer this option from our head office in Huntingwood, NSW. If you’re searching for ‘helium balloons near me’, and neither of these locations are close to you, you’ll be glad to know that we can conveniently deliver your balloons straight to your door. 

Save With Our Reliable Party Balloons

At Koch & Co, we are wholesale helium balloon suppliers, which means that we import our balloons and accessories independently. This enables us to ensure that all our balloon products are made from only the highest quality materials. Importing them directly also means we can pass on the savings to our customers, with further discounts available for helium balloon bulk purchases. If you’re taking a DIY approach, these savings can still apply as you may be eligible for bulk discounts if you purchase as few as two packs of balloons. 

Celebrate Birthday & Anniversary Milestones With Helium Number Balloons

At Koch & Co, we stock premium, foil helium number balloons in classic colours. These balloons conveniently self seal, and as such, do not require heat sealing. For a more specific display, match your number balloons with our range of letter balloons. These balloons feature every letter from A-Z so you can get creative with your event displays. When considering letter and number combinations, you can opt to keep it traditional, with a ‘Sweet 16’, or you can be as specific as you please. Spell out your business name, your new shared last name, or spell out the birthday person’s name and age for the world to see.

Convenient Party Supplies Delivered Straight To Your Door

If you need balloons, at Koch & Co, you can get your wholesale helium balloons delivered straight to your door Australia wide. If you’re after helium tanks, balloon weights, curling ribbon, balloon confetti, and a balloon opener (so you can stuff your balloons with confetti), you can conveniently receive it all delivered, in one box, to your front door. All of your balloon needs effortlessly sorted. 

 
Can any balloons be filled with helium?

All balloons can be filled with helium, but not all of them will float. To be lighter than the air around them, any balloon needs to contain a certain amount of helium. The more helium, the greater the float, but the heavier the balloon itself is, the more mass there is to float.
 
At Koch & Co, we are helium balloon wholesale suppliers, and as such, stock an extensive range of latex balloons (both standard and helium-grade varieties), as well as foil and bubble balloons. Across these varieties, all of which are compatible with our helium tank kits, you’ll find a massive range of colours and shapes, with something to suit every occasion. Whether you’re celebrating a new baby, a milestone birthday, or an anniversary, we have balloons to suit your event. 
 
Our extensive range covers four key types of balloons:

  • 9-inch latex balloons are standard for a reason. These balloons can contain enough helium to be lighter than air. The weight of the latex balloon itself is light enough to not affect the float of the balloon. If you want to float smaller balloons than this size, you may encounter some issues because of the reduced amount of helium they can contain. 
  •  When making your selections, please keep in mind that not all latex balloons are the same. Standard latex balloons do not always hold helium as well as helium-grade balloons, with the latter performing more reliably for extended periods of time over the course of a party. Standard latex balloons can be filled with helium, but will not float on a string in the same way a helium latex balloon will. Helium-grade latex balloons are designed for helium inflation with a longer float time than the standard latex variety. 
  • Our mylar foil balloons are non-plastic balloons that are available in a wide variety of novelty shapes. A foil balloon inflated with helium will float for 1 to 4 weeks depending on the balloon size and environment. Keep in mind when making your selections that foil is heavier than latex, and as such, to counteract the weight of the foil and be able to float; the balloon needs to be bigger than a standard latex balloon. We recommend choosing larger foil balloons (anything from 18-inches or 45cm in diameter) if you intend to fill them with helium.
  • Plastic “bubble” balloons are the longest lasting of our range, with a lifespan of 3-4 weeks. Inflating these balloons requires a little more know-how, with the process involving stretching, stuffing, and a Koch Heat Sealer.
How to blow balloons with helium?

Inflating balloons with helium can seem complicated, but with the right set up, you can establish a good rhythm, and get your balloons inflated in no time. Know that balloons that have been designed to be filled with helium tend to inflate quickly, so make sure you have all the steps clear in your mind before commencing.  

  1. Purchase a helium tank kit at Koch & Co.
  2. Make sure there are no children in your workspace. 
  3. Fasten your helium tank to a secure support in an upright position. 
  4. Remove the rubber tip cap and attach the balloon nozzle.
  5. Open the tank valve by rotating the handle anti-clockwise.
  6. Slide the neck of the balloon over the balloon nozzle.
  7. While holding the end of the balloon onto the nozzle with one hand, use your other hand to lift up the nozzle to release the helium and fill the balloon.
  8. Inflate the balloon to the recommended size. Latex balloons should have a round shape when inflated. Balloons shaped like pears or light bulbs are overinflated and more likely to burst.
  9. Remove the helium filled balloon from the nozzle, and knot or clip the end of the balloon to secure it. Please take caution as the balloon might fly away. To prevent this from happening, we recommend immediately tying a ribbon onto your balloon, and attaching the other end of the ribbon to an anchor, like a balloon weight.
  10. After use, close the tank valve by rotating the handle clockwise. Ensure the tank valve is tightly closed when not in use.
  11. Watch our instructional video on how to blow balloons with a helium tank.
Do you need to use helium for a balloon arch?

A balloon arch may look gravity-defying, like balloons floating together in formation but rather than being filled with helium, these arches are usually built around a metal arch or backdrop frame. The frame is the skeleton, and the air-inflated balloons are arranged on a string or garland that is secured to the frame. 

Does a balloon garland need helium?

A balloon garland is a balloon arrangement anchored to a frame. The clustered balloons often have the effect of floating, but are usually filled with air, and are not helium filled balloons. We recommend using a balloon air pump, which will help you to inflate your balloon clusters quickly and quietly. Furthermore, balloon garlands can require a great number of balloons. Koch & Co’s balloon garland kits contain 120 pieces each so an air pump can make a big difference. 

How long do helium party balloons last?

Different materials of balloons will contain helium for different periods of time, and this, combined with the size and shape of the balloon will also affect the length of time they will float. Please see the information below for a general guide:

  • 9” latex balloons = Up to 87-90 balloons, 6-8 hrs float time
  • 12” latex balloons = Up to 44-46 balloons, 6-8 hrs float time
  • 18” foil balloons = Up to 44-46 balloons, 3-5 days float time
How to keep balloons filled with helium from deflating?

Though your balloons deflating is inevitable, there are some things you can do to slow the deflation process, and some factors you can avoid that accelerate the deflation process, too. One of the key moves you can make when filling balloons with helium is deciding when you are going to inflate them. Based on your balloon material type and size, you should have an estimate on their float time, so time this to overlap with the duration of your event.   

  • Latex balloons stay afloat for four to sixteen hours. If you need your balloons floating for longer than six to eight hours, consider using Koch & Co’s TOP Float. Our TOP Float is a balloon booster treatment gel that is non-toxic and biodegradable. Adding this gel to balloons before inflation can extend float time to last between four and six days.
  • When inflating your balloons, ensure you are tying them with a tight knot. After this, if you are attaching a lightweight ribbon like a curling ribbon, tie this ribbon onto the balloon at the neck, rather than below the knot. Adding an extra ‘choke point’ above the knot will help to contain more helium within the balloon, slowing leakage so that your balloon stays afloat for longer. 
  • After inflating your balloons, some extra measures you can take involve things like cooling down your balloons. For example, if you’re enjoying outdoor party helium balloons on a hot day, consider cooling them off every once in a while with a spray of water. The heat from the sun will be expanding the helium molecules in your balloons, which usually leads to more leakage, and thus, quicker deflation. Under these circumstances, some recommend filling balloons to 90% capacity to accommodate expanding helium molecules, and minimise leakage. 
  • This brings to the fore the issue of under or overinflation. Overinflated balloons take on a pear or light bulb shape. Resist the impulse to fill your balloon more so that it will ‘float longer’, and instead stop when your balloons have reached a round shape. If you’re inflating a foil balloon, inflate to a point that the seams still have some creases, and are not totally distended. On the other hand, underinflating a balloon can also negatively impact float time because if a balloon doesn’t contain enough helium to be lighter than the air around it, it cannot float.
Can you refill balloons with helium?

Helium filled balloons can be reused (reinflated) - assuming the balloon itself is still intact. To ascertain whether your balloon has any tears in it, inflate your balloon and listen quietly for the sound of escaping air. 
 
Latex balloons begin deteriorating very quickly after initial use, especially if they’ve been exposed to sunlight. This can make unknotting and refilling a latex balloon without tearing quite tricky, and may take some practice.
