Why All the Fuss About Buying the Best Lunchbox for School?

Buyer’s Guide to Selecting the Best Lunchbox for School

  • The Size of the Lunchbox

It comes down to your child's appetite, age, and how many hours they will be at kindergarten or preschool. Before you buy, consider how much food you need to pack and the space and compartments you require to include as much variety as possible. Perhaps space for an ice pack and a water bottle. But beware as too large a lunchbox may also work against you, as it may not fit inside your child's backpack. 

  • Food-safe Material

Lunchboxes should be made from food-safe material, free of any harmful chemicals or dyes and BPA-free. Environmentally friendly; natural wheat fibre seems to have gained in popularity. 

Of course, some parents who are averse to using any form of plastic have the option of buying stainless steel lunchboxes. But these are often heavier and possibly more cumbersome to handle, and it may look too 'boring' for a small child.

  • Functionality

It is unique to each child's needs, the age of your child, and features that contribute to the safety and freshness of the food. While various 'snackable' foods are essential to kids, space for an ice pack in an insulated box may be a priority during hot weather. Equally important is for your child to open and close their lunchbox unassisted.

  • Your Child’s Food Preferences

Some kids refuse to move away from PB&J sandwiches. So you would need a larger compartment for at least two sandwiches and smaller ones for fruit and other healthy snacks. Some lunchboxes have smaller containers to pack yoghurt, dips, peanut butter or sauces that would need space for small containers.

  • The Cost Factor

Yes, the cost is always a consideration. However, some parents only want a lunchbox that will last a year or buy a few lower-cost ones. Small kids love vibrant colours, and character images displayed on their lunchbox is sure to be a winner! It’s a great way to coerce picky eaters to eat what you’ve packed in their lunchbox. 

Sometimes spending between $14 and $25 will surprise you when a lunchbox lasts way beyond your expectations. It depends on whether you adhere to the manufacturer’s instructions and if it’s being hand-washed for more control. How your child handles the lunchbox will also determine its lifespan.  

Key Takeaways

Gone are the days of plastic or foil-wrapped sandwiches for school. With internet shopping, we have a plethora of innovative, well-priced lunchboxes that boast all the features that suit every child's needs. And as a parent, you have the option of avoiding plastic containers and opt for stainless steel or ones made with organic, biodegradable material.

What’s important is that a lunchbox should be child-focused and age-appropriate. It should meet your little one’s food preferences, and the colour needs to be a key consideration as well. Some lunchboxes have a matching insulated lunch bag which may be easier to pop in an ice pack and water bottle.

Competition is fierce among brands, so every parent can afford a moderately-priced Bento box that suits their pocket while having all the essential features of their highly-expensive and over-priced counterparts.

Frequently Asked Questions

Why are lunchboxes called Bento?

The Bento box has a long history in Japanese culinary culture and dates back more than 1,000 years. The idea was derived from the farmers’ seedboxes, and the multiple compartments were convenient to pack a staple diet comprising different dishes such as rice, fish, and vegetables. The Japanese word Bento comes from Chinese Southern Song slang Biandang, which means convenient!

Different countries across Asia adopted the Bento box adding their indigenous culinary flair in packing a selection of dishes to provide a balanced lunch. However, it went from convenience to luxury in 1912 (during the Taishō period) when the aluminum Bento captured the imagination of nations across the globe. The Bento containers made from polypropylene and extruded polystyrene (EPS) went viral at fast food outlets and take-outs. The negative impact on the environment continues to wreak havoc on global warming and extreme weather patterns globally.

What environmentally-friendly materials are used in Bento Lunchboxes?

Traditional Bento lunch boxes are made from wood, bamboo, food-grade stainless steel, silicone, and food-safe plastic (free of BPA-Bisphenol A, PVC-Polyvinyl chloride, and phthalates).

However, glass is deemed the most versatile and environmentally friendly, followed by stainless steel, wheat, bamboo, and gelatin film. These are all biodegradable and not hazardous to the planet. You can expect to pay more for these Bento lunchboxes.
