Planning a celebration, whether it's a milestone birthday or a themed get-together, involves many details. Finding the right decorations is key to creating a memorable atmosphere, and party balloons are a simple yet effective way to transform any space. However, with so many options available, from giant numbers to specific character designs, choosing the right ones can feel overwhelming.
This guide is designed to help you navigate the choices. We will outline what to look for when selecting party balloons and share some of our top recommendations to help you find the perfect fit for your event.
What to Consider When Buying Party Balloons
Making a great choice comes down to a few practical considerations. Keeping these points in mind will help you select decorations that not only look fantastic but are also suitable for your venue and celebration type.
Foil or Latex?
The material of your balloon affects its appearance, durability and use.
- Foil balloons are made from a thin, non-stretchy metallic film. They are known for holding their shape and staying inflated with helium for much longer than latex—often for several days or even weeks. They come in a huge variety of shapes, sizes and printed designs, making them ideal for themed party decorations and number balloons.
- Latex balloons are the classic, stretchy rubber balloons. They are generally more affordable and are perfect for filling a room or creating large, colourful displays. However, they are porous and will lose helium more quickly, typically lasting for about 8-12 hours.
Helium or Air Inflation?
How you plan to display your balloons will determine whether you need helium or just air.
- Helium balloons are lighter than air, allowing them to float. This is perfect for creating balloon bouquets, table centrepieces or having them float to the ceiling. Most foil balloons are designed for helium but check the product description, as some smaller shapes may not float.
- Air-filled balloons will not float but are an excellent choice for creating balloon garlands, arches or attaching to walls as part of a photo backdrop. This is a more cost-effective option, and many foil balloons feature self-sealing valves and tabs for easy air inflation and hanging.
Safety and UK Standards
When purchasing party supplies, it's important to be aware of safety guidelines. Look for products that are manufactured to UKCA/CE standards. For safety, always attach a non-metallic ribbon and a balloon weight to helium-filled foil balloons, and never use them near overhead power lines. Always supervise young children around uninflated or broken balloons to prevent choking hazards.

Frequently Asked Questions
How long do foil helium balloons stay inflated?
Foil balloons have a much longer float time than latex balloons. Because the Mylar material is non-porous, it retains helium very effectively. A standard foil helium balloon will typically stay fully inflated for several days, and it is not uncommon for them to remain floating for a week or more, depending on environmental conditions like temperature.
Can I reuse foil party balloons?
Yes, many foil balloons can be deflated and reused. Most are equipped with a self-sealing valve. To deflate one, you can gently insert a drinking straw into the valve until you feel the air begin to release. Press down carefully on the balloon to expel the air, then fold it flat for storage. This makes them a practical option for those who host events regularly.
What is the difference between Mylar and foil balloons?
The terms are often used interchangeably. Mylar is a brand name for a type of stretched polyester film (BoPET) that is coated with a metallic finish. Most of the shiny, shaped foil balloons you see on the market are made from this material. So, when you see a product described as a "foil balloon," it is almost certainly made of Mylar or a very similar material.
