Buy Party Balloons: A Guide to Balloon Sets, Foil Balloons and Helium

Party balloons should decorate a celebration without important items being missing just before it starts or the balloons losing their shape after a short time. That is why colour and design are not the only things to consider when buying. The filling method, material, quantity, size and whether accessories such as helium gas for balloons are actually needed are all important factors.

Common pitfalls when buying party balloons

1. Air filling and helium filling are confused

Not every balloon floats automatically. Latex balloons can be filled with air or helium, but helium is needed to make them float. Many foil balloons are also suitable for both filling methods. When filled with air, however, they remain in the desired position as wall, table or backdrop decorations.

Before buying, make sure you know:

  • Should the balloon decoration float?
  • Will balloon arches or garlands mainly be attached to walls and tables?
  • Is a suitable filling valve available?
  • Will you also need helium gas for balloons?

2. The quantity does not match the planned decoration

A pack containing just a few balloons is enough for individual accents, but not always for a balloon arch. Conversely, a comprehensive balloon set may create unnecessary leftovers for a small table decoration. Check whether the stated quantity actually includes all the elements or whether accessories need to be bought separately.

3. The design, size and intended use do not match

A large foil balloon can create a focal point, but it does not replace a versatile mix of small and medium-sized air-filled balloons. With birthday balloons, unicorn balloons, NFL balloons or Happy Birthday balloons, you should also check whether the design suits the age group and venue.

Important buying criteria for air-filled balloons and foil balloons

Material and filling method

Latex is suitable for classic air-filled balloons and balloon arches. Foil is often used for character balloons and letter balloons. With foil balloons, an automatic sealing valve can make filling easier. Even so, the filling opening should be compatible with the nozzle you have available.

Size is also relevant when using helium: a small latex balloon requires less gas than a large foil balloon. The number you can actually fill therefore depends on the balloon size, filling level and any gas reserve.

Dimensions and quantity

For planning purposes, diameter and pack contents are more important than general advertising claims. A round foil balloon with a diameter of around 45 cm can be used as an individual accent or as part of a balloon bouquet. A set with 120 pieces, on the other hand, offers more creative flexibility for a children’s party or balloon arch.

Safety and storage

Balloons are not toys. Uninflated or damaged balloons should be kept out of the reach of young children. Children under three are at risk of choking on small parts or burst balloons. Balloons should be used under adult supervision.

Helium cylinders contain gas under pressure. The cylinder must not be heated and should be kept in a well-ventilated area. Helium must not be inhaled or released uncontrollably outdoors. Dispose of disposable cylinders in accordance with local requirements, for example through a suitable recycling facility.

How to prepare helium balloons properly

If party balloons are meant to float, first calculate the amount of gas required. According to the product details, the Balloon Gas for Up to 50 Balloons cylinder contains 400 litres of helium with a purity of 99.6 per cent and is designed for up to 50 balloons. A filling valve is integrated. The product is specified as suitable for latex, foil, heart-shaped and LED balloons.

The “up to 50 balloons” figure is a guideline. Large balloons require more gas than small ones. Inflate the balloons as close to the event as possible, attach them with string and avoid contact with sharp edges, radiators and rough surfaces.

Party balloon FAQ

How long do helium balloons last?

Floating time depends on the material, size, amount of gas, temperature and surroundings. Latex balloons generally lose helium more quickly than foil balloons. Foil balloons can be reused several times if handled carefully, provided the valve and material remain undamaged.

How many balloons can be filled with one helium cylinder?

That depends on the balloon size. According to the product details, the cylinder mentioned above is designed for up to 50 balloons. For accurate planning, you should take the size of each air-filled or foil balloon into account and allow for a reserve.

Are party balloons suitable for young children?

Balloons should only be used under adult supervision. Uninflated and burst balloons can pose a choking hazard. Always follow the age recommendation and safety instructions on the product packaging.
