Foil vs latex: which balloon for which job
Buyers new to the category often treat foil and latex as two colours of the same product. They behave differently, last differently and sell into different baskets.
Foil (metallised PET)
- Holds gas for days to weeks — good for pre-filled retail and event work
- Can be printed with fine detail and metallics — good for licensed and number shapes
- Does not stretch, so shape is fixed by the die
- Reusable if deflated carefully
Latex
- Porous: helium escapes in 8-12 hours, so it is an inflation-day product
- Stretches — one size covers a range, and garlands need that flexibility
- Much lower unit cost, sold in bulk bags
- Biodegradable, which increasingly matters in the EU
How the two work together
Most professional garlands are latex-based, because latex stretches and grips the tape. Foil is used for the feature element — a number, a character, a printed shape. That is why a serious supplier carries both: the kit sells as one SKU but is two production lines.
What to tell your customer
One sentence prevents most complaints: "Latex balloons float for about a day; foil balloons float for days to weeks." Put it on the product page and on the pack. Customers who know this do not return a latex order the next morning.
Stocking implication
Foil rewards depth — fewer SKUs, more units, because it stores flat and does not age. Latex rewards width — many colours and sizes, lower depth, because it perishes. Budget your inventory the same way.
