This type of balloon is often called a foil, Mylar®, or a metallic balloon. However, they are not made from foil as you would imagine. They are actually made from a bi-axial nylon impregnated with aluminium on the outside to hold in the small molecules of helium or balloon gas and laminated with a polyethylene (plastic with a low melting point) coating on the inside to allow the material to be heat sealed. The material is then cut to the shape required and heat sealed at the edges.
Due to their material, Microfoil® balloons are less porous than latex balloons, so they stay inflated longer. This type of balloon is NOT biodegradable.

Qualatex® Microfoil balloons are available in a wide range of colours that coordinate with the Qualatex latex colour range. Microfoil balloons range from 4” to 36” with a wide variety of shapes and designs.

Correctly inflated Microfoil balloons are firm with uniform creases along the seams (you must leave space for heat expansion). The 18” size and larger can be inflated with helium or balloon gas. For correct inflation, use an Automatic Foil Balloon inflator. These inflators have been designed to fill any size or shape Microfoil balloon to the optimum size (leaving the correct amount of creases) and will automatically cut-off when the balloon has reached its correct size. Using the wrong type of inflator can cause damage to the valve of a Microfoil balloon, plus you can easily overinflate these balloons, which could cause them to pop.
