Flat Stacks Australia is a family-owned business
Flat Stacks Australia is a family-owned and operated business founded by Julie, a mother of three turned entrepreneur, and her children Liam and Courtney. Julie's passion for home and family life inspired her to create Flat Stacks, bright and colourful collapsible containers that transform kitchens into organised, stress-free spaces.
Flat Stacks Australia was launched in 2014 as the original collapsible silicone containers, with a mission to help Australian families declutter their kitchens. The company's commitment to innovation and improvement has led to the development of high-quality, durable products that are microwave-safe, dishwasher-safe, and freezer-friendly.
The family's dedication to improving the lives of their customers is evident in the thoughtful design of Flat Stacks. The containers are stackable, space-saving, and colour-coded, making it easy for users to find what they need and keep their kitchens tidy. The silicone material is also long-lasting, reducing plastic waste and protecting the environment.
Flat Stacks Australia offers a range of products, including the Original Flat Stacks and the Ovenware Flat Stacks, which are oven-safe and can be used on air fryers, microwaves, and BBQ plates. The company provides free delivery within Australia for orders over $149 and express shipping options for those in a hurry.

The containers are made from 100% silicone
Flat Stacks is a family-owned and operated business founded by Julie, a mother of three turned entrepreneur. The company is based in Australia, with all orders shipped from their fulfilment centre in Sydney.
Flat Stacks are made from 100% silicone, with no fillers. This makes them thicker and stronger than competitors' products. The silicone used is high-quality, food-grade, and BPA and BPS-free. It is also more durable than plastic, withstanding extreme temperatures, stains, and odours without warping or cracking. This makes Flat Stacks eco-friendly, as they outlast plastic containers. The containers are also stackable, airtight, and colour-coded, making them a great solution for kitchen organisation. They are safe for use in the fridge, freezer, microwave, and dishwasher.
Flat Stacks come in a variety of shapes and sizes, including round and rectangular sets. They also offer Ovenware sets that are oven-safe and can be used on air fryers, microwaves, and BBQ plates (though not on direct grill contact or open flames). The Ovenware sets are navy blue with soft silicone lids, while the Original Flat Stacks come in various colours and have hard lids.
Flat Stacks has received positive reviews from customers who appreciate the space-saving design, durability, and convenience of the containers. The company offers a 5-year warranty and a 30-day money-back guarantee, making it a risk-free purchase for those looking to declutter their kitchens.

They are stackable, airtight, and colour-coded
Flat Stacks are stackable, airtight, and colour-coded. They are designed to transform your kitchen into an organised, stress-free space. The stackable feature allows for convenient storage in the refrigerator, cupboard, or freezer, maximising space and creating a neat appearance. The airtight seal ensures food stays fresh for longer, reducing food waste and saving money.
The colour-coded design adds a touch of brightness to your kitchen while also offering a functional benefit. With matching colour lids, you can easily identify and retrieve the correct container without the frustration of searching for missing lids. This colour-coding system simplifies organisation and saves time in the kitchen.
Flat Stacks are crafted from high-quality, food-grade silicone, which is thicker and stronger than competitors' products. Silicone is a durable material that withstands extreme temperatures without warping or cracking, making it microwave, dishwasher, and freezer-safe. The silicone construction also contributes to the containers' collapsibility, allowing them to shrink to fit the contents and save space.
The colour-coding, combined with stackability and airtightness, makes Flat Stacks a comprehensive solution for kitchen organisation. They eliminate the need for transferring contents between containers and reduce the time spent searching for lids. These features contribute to a stress-free kitchen experience, aligning with the product's mission to create a calm and controlled environment for families.

Ovenware Flat Stacks are oven-safe and microwave-safe
Flat Stacks are a family-owned and operated business that offers a range of kitchenware and food storage solutions. Their products are designed to help transform your kitchen into an organised, stress-free space. One of their key products is the Flat Stacks Ovenware, which offers the same benefits as their original collapsible containers but with added functionality for oven use.
The Ovenware Flat Stacks are designed to be oven-safe, meaning they can withstand higher temperatures than the original Flat Stacks. This makes them suitable for use in ovens, as well as air fryers, microwaves, and even on BBQ plates, as long as they are not placed directly on the grill or in open flames. The oven-safe design ensures that you can use the containers for cooking and reheating food in various appliances, making them a versatile addition to your kitchen.
To easily distinguish them from the original Flat Stacks, the Ovenware Flat Stacks feature a navy blue colour and come with soft silicone lids. These lids are designed to be easily identifiable and provide an airtight seal, keeping your food fresh for longer. The soft silicone lids also make it convenient to collapse the containers for storage when not in use, saving you valuable space in your kitchen cabinets and refrigerator.
In addition to their oven-safe capabilities, the Ovenware Flat Stacks are also microwave-safe. This means you can confidently use them to heat up leftovers or defrost meals in the microwave without worrying about any safety hazards. The microwave-safe feature further adds to the convenience and versatility of these containers, making them a handy tool for your daily meal preparation and cooking needs.
Overall, the Ovenware Flat Stacks from Flat Stacks Australia offer a functional and reliable solution for anyone looking to declutter and organise their kitchen. With their oven-safe and microwave-safe properties, these containers provide a versatile option for food storage, cooking, and reheating, all while saving you space and reducing clutter in your kitchen.
