Make Giant Ice Blocks at Home with The Big Block Tray

Looking for a serious solution to keep things cold — from your recovery routine to your fishing haul? Say goodbye to servo bags and cracked ice cream containers. The Big Block Tray is Australia’s largest silicone ice block mould, designed to freeze a massive 5.5KG ice block right in your home freezer.

Whether you're heading off camping, or filling the eski for a full-day fish, or prepping for ice baths, this tray gives you the freedom to make your own block ice — cheap, easy, and reusable.

You won’t find anything this large, this tough, with a stainless steel rim and a lid anywhere else in Australia. We are the original creators.

Each Freeflo tray is crafted from premium, food-grade silicone with a stainless steel frame for added strength. They’re built to last and far more durable than cheap alternatives. They are also BPA free (no nasties).

Each Big Block Tray Original measures 31 × 21 × 12 cm and produces a 5.5 kg ice block. The Big block trays are not stackable.

Each Little Block Tray Pro measures 29 x 18 x 13 cm and produces a 3.5kg ice block. The Little Block Tray Pro's are stackable.

The moulds typically take around 48 hours or more to fully freeze, depending on freezer size and settings. For best results, fill with cold water, leave a little space for expansion, and place flat in the coldest section of your freezer.

Yes. Simply run warm water over the base or leave the tray in the sun for 1–2 minutes. Then push the block up from underneath — there is absolutely zero force required.

Absolutely. The reinforced stainless steel rim keeps the tray stable while full. Use two hands and keep it level to avoid spills.

Yes.

They freeze solid and hold temperature just like regular ice — without melting into water.

The difference?

No flooding. No soggy food. No watered-down drinks.

In our Aussie heat test (28°C):

• Mini lasted 36 hours

• Max lasted 60 hours

That was using just one bag.

More bags = longer cold.

Performance will vary based on your esky, packing method, and outside temperature — but they’re built to go the distance.

Purified water.

That’s it.

No gel.

No chemicals.

No weird blue liquid.

Just purified water sealed inside a durable, BPA-free outer shell.

Yes.

They’re sealed, BPA-free, and food safe.

You can use them directly in drinks, around food, or in your esky without worry.

Mini (2kg) → 120 cubes

Max (5kg) → 130 cubes

Exact weight can vary slightly depending on fill level, but cube count remains consistent.

Simple.

After use:

1. 
   Rinse with water.
   
2. 
   Let them dry.
   
3. 
   Refreeze.
   

That’s it.

Freeze once. Reuse again and again.
