Leakproof matters more than you think
Few things ruin a school bag faster than leaking yoghurt
A quality lunch box should be leak-resistant for yoghurt, hummus, dips and thick sauces. Keep in mind most compartment lunch boxes are designed for thick, wet foods, not thin liquids like soup or salad dressing.
Hot lunches are becoming more popular
Australian families are increasingly packing warm lunches during winter with an insulated food jar a great way to keep children interested when they've lost the plot on sandwiches.
Easy cleaning saves time
Parents quickly discover that the easiest lunch box to clean is often the one that gets used every day. Look for dishwasher-safe components, rounded corners, removable seals, and stain-resistant materials. Stainless steel is particularly good at resisting food stains and lingering odours.
