Pros & Cons of Different Lunch Box Materials

There are many factors you should pay attention to when picking a lunch box for your kid – starting with choosing the right material. From plastic and silicone to glass and stainless steel, options are pretty much endless, and they all have their own pros and cons.


Plastic lunch boxes are a pretty popular option because they’re budget-friendly and lightweight, but they’re not extremely durable and people often avoid them due to BPA concerns.

Stainless Steel

Stainless steel is one of the most durable lunch box materials, amazing at heat retention, but these lunch boxes are not extremely popular due to their heaviness and the lack of fun kid-friendly designs.


Glass is a pretty popular lunch box material because it’s dishwasher-friendly and great at retaining heat, but many people avoid it because it’s easily breakable and pretty heavy.


Silicone lunch boxes have become pretty popular in recent years thanks to their lightweight, flexible compact design. Unfortunately, they’re not great at retaining heat and can pick up odors over time.


If you’re looking for the most eco-friendly option on the market, a bamboo lunch box is just the thing you need. Despite being lightweight and durable, bamboo lunch boxes don’t retain heat so well and they require a more careful cleaning process than other materials.
