Is a metal lunch box better than plastic?

For years the go-to option for lunch boxes has been plastic.  However, as our awareness grows about the impact plastic is having on our planet and even our health, we share our thoughts on why metal is a better alternative to plastic when it comes to storing your lunch.

Plastic lunch boxes can sometimes contain harmful chemicals such as BPA (bisphenol A) or phthalates, which may leach into food, especially when exposed to heat.   These chemicals have been linked to potential health concerns. BPA has been associated with hormonal disruptions, while certain phthalates are considered endocrine disruptors.  If you have concerns about chemical exposure, choosing a metal lunch box might be a safer option.


If you are looking for a tough lunch box, that will last for years, then look no further!  Metal lunch boxes tend to be more durable and can withstand rough handling, drops, and impacts better than plastic lunch boxes. They are less likely to crack or break, making them a great reusable option that will really go the distance. 

Environmental Impact

Metal lunch boxes are typically more environmentally friendly than plastic ones. They are reusable and have a longer lifespan, reducing waste generated from disposable plastic lunch boxes. If sustainability is important to you, choosing a metal lunch box might align better with your values.

Cleaning and Maintenance

Metal lunch boxes are often easier to clean and less prone to staining than plastic ones. Metal lunch boxes typically have a non-porous surface, meaning they don't have tiny pores or microscopic openings where food particles or stains can get trapped. This makes it easier to wipe clean and prevents odors and stains from lingering.  Metals like stainless steel are naturally more resistant to staining than plastic. They are less likely to absorb colors or retain strong odors from food. This makes metal lunch boxes easier to maintain their appearance over time.  Plastic lunch boxes can sometimes retain odours and stains, requiring more thorough cleaning and maintenance.


Whilst metal lunch boxes are slightly heavier than plastic ones, they are perfectly portable. Our leakproof stainless steel lunch boxes and snack pots, mean that you can carry a lot of food inside without the risk of spillage.

Both metal and plastic lunch boxes come in a variety of styles and designs. We personally love the retro look of our metal lunch boxes.  They really do stand out from the crowd!
