Insulated Food Jar For Kids: The Easy Way To Pack Warm School Lunches
As a mum who packs school lunches and work lunches almost every day, I know how quickly lunchbox inspiration runs out. Sandwiches get boring, kids get fussy, and sometimes you simply want a warm lunch option that feels more satisfying—especially during winter.
That's where an insulated food jar can completely change the way you pack lunches.
A quality insulated food jar allows you to send warm meals to school without needing a microwave. From pasta and noodles to leftovers and soups, it opens up a whole new range of lunch options that many kids actually look forward to eating.
If you're looking for a food jar that can hold a real lunch rather than just a snack, explore the Large Insulated Food Jar Collection. With a generous 800ml capacity, Spixal food jars are designed for growing kids, teenagers, and busy families who need more space than most food jars offer.
They've also been designed to fit upright inside the Work Lunch Bags range and coordinate with the colourful Kids Backpacks collection, making it easier to create a complete school lunch system.
What Is An Insulated Food Jar?
An insulated food jar is a double-wall container designed to keep food hot or cold for hours.
Most quality food jars use stainless steel construction with vacuum insulation between the inner and outer walls. This creates a barrier that slows temperature transfer, helping meals stay warm until lunchtime.
They're ideal for:
- Pasta dishes
- Fried rice
- Mac and cheese
- Butter chicken and rice
- Noodles
- Soup
- Dumplings
- Chicken nuggets
- Leftovers
- Porridge
Why Parents Love Insulated Food Jars
Many parents start looking for an insulated food jar because they're tired of packing the same lunch every day.
Adding warm lunch options can help:
- Create more variety
- Reduce lunchbox boredom
- Use leftovers instead of wasting food
- Save time preparing separate lunches
- Make winter lunches more enjoyable
One of my favourite lunchbox hacks is simply packing dinner leftovers in an insulated food jar. It saves preparation time and means you're already cooking one meal for two purposes.
What Size Insulated Food Jar Is Best For Kids?
This is one of the biggest mistakes parents make when buying a food jar.
Many food jars on the market range between 200ml and 500ml. While that can work for younger children or snacks, many school-aged kids quickly outgrow them.
To put it into perspective:
- 200ml = small snack-sized portion
- 300ml–400ml = light lunch
- 500ml = average meal
- 800ml = full-sized lunch
The larger the child, the more important capacity becomes.
Teenagers, active kids, and growing children often need significantly larger meals than smaller food jars can comfortably hold.
Why The Spixal Large Food Jar Is Different
The Spixal Large Insulated Food Jar was designed specifically to solve the size problem many families experience.
Instead of creating another small food jar, Spixal developed an oversized 800ml design that comfortably fits a complete lunch.
Key features include:
- Large 800ml capacity
- 304 food-grade stainless steel
- BPA-free materials
- FDA tested materials
- Leakproof lid
- Double-wall vacuum insulation
- Dishwasher safe
- Wide opening for easy filling and cleaning
- Available in six coordinated colours
For many families, the biggest benefit is simply being able to pack enough food.
The jar comfortably holds meals that smaller food jars struggle with, including larger pasta serves, rice dishes, leftovers, or up to 12 chicken nuggets.

How To Keep Food Hot Until Lunch
A simple trick many parents don't know is pre-heating the food jar before packing lunch.
- Fill the food jar with boiling water.
- Leave for 5–10 minutes.
- Heat food until steaming hot.
- Empty the water.
- Add food immediately.
- Close the lid tightly.
This simple step can significantly improve heat retention.
What Materials Should You Look For?
The best insulated food jars typically use 304 stainless steel.
This material is widely trusted for food storage because it is:
- Durable
- Food safe
- Corrosion resistant
- Easy to clean
- Odour resistant
The Spixal Large Insulated Food Jar uses 304 stainless steel and BPA-free materials that have passed FDA testing standards.

They've been designed to coordinate with matching Kids Backpacks, helping create a more organised and coordinated school setup.
