Pros and Cons at a Glance
Does my Blockhuette stainless steel lunch box actually have any disadvantages?
We would be lying if we claimed that using stainless steel lunch boxes only comes with advantages. Continue reading to learn more about the pros and cons of stainless steel lunch boxes and to see why stainless steel is still the better alternative for you!
The short answer: a stainless steel lunch box outlasts plastic by years, is plastic-free and even goes in the oven — in return it costs more upfront and stays out of the microwave. If you already know you want one, have a look at the stainless steel lunch box for adults. For everyone else, here are the honest pros and cons.
Disadvantages of stainless steel lunch boxes
Incompatibility of stainless steel lunch boxes with microwaves
Important to know: Stainless steel and microwaves are not good friends. Using a stainless steel lunch box for heating in the microwave could cause unwanted sparking. This poses risks not only to the user but also potentially spells the end for the microwave. Plastic is an alternative, but caution is advised: its suitability for microwave use should be checked in advance. An even better choice is glass containers, which are clearly the best option here. The oven, on the other hand, is no problem at all for stainless steel — more on that in the pros.
Problem with fingerprints on the stainless steel lunch box
Smooth and yet problematic: untreated stainless steel tends to attract fingerprints. If you value a flawless appearance but don't want to do without stainless steel, we recommend choosing a brushed version. This is not only visually appealing, but also practical, as fingerprints are less visible. A simple wipe is all it takes to restore the original shine.
Stainless steel lunch boxes and scratches
Over time, small reminders can appear on any stainless steel surface in the form of scratches, whether from key rings or cutlery. A tip: Surfaces with a matt or brushed finish are less likely to show scratches.
Cost factor
The flip side of the coin with stainless steel: quality has its price, which is often higher than that of plastic alternatives. Processing stainless steel is an art in itself, which is also reflected in the price - not to mention the higher transportation costs. As a long-term investment, however, it may be worth considering. It also helps that a worn seal or a lost lid does not mean a new box — every part is available separately.
Pros for a stainless steel lunch box
Oven-ready and heat-proof
Stainless steel, a champion of durability and heat resistance, melts only at an impressive 1510 °C (2750 °F). Therefore, your stainless steel lunch box is perfectly suited for the oven, whether for reheating or even for baking directly. Imagine preparing a lasagna or even your favorite cake in the lunch box and taking it with you. The scope for culinary creativity is immense.
Health first: BPA-free stainless steel lunch box
Compared to plastics, stainless steel is free from BPA, phthalates, and other concerning additives. This safety is essential in today's world, where health and well-being are in focus.
Durability and resistance
While plastic degrades in quality over time and becomes porous, stainless steel remains shape-stable and colorfast. Investing in a stainless steel lunch box pays off, as it remains flawless even after years of intensive use.
No microplastic pollution due to stainless steel lunch box
Another advantage: Using a stainless steel lunch box does not risk microplastic particles getting into your meals – a comforting thought while enjoying your food.
Robustness that convinces
Stainless steel represents robustness and durability. A lunch box made from this material withstands almost everything, from high to low temperatures, and also survives the occasional drop nearly unscathed.
Rust? Not an issue for the stainless steel lunch box
When purchasing, choose the right type of stainless steel, such as 18/8 stainless steel, and you will not have any problems with rust. These lunch boxes are true long-runners in your daily life. And they can even go in the dishwasher!
Hygiene made easy with stainless steel lunch boxes
The smooth surface of stainless steel simplifies cleaning and keeps bacteria and mold at bay. Thus, a stainless steel lunch box is not only practical but also a win for your health.
Safe and compatible
Generally, stainless steel lunch boxes are safe and not harmful to health. However, those sensitive to nickel should opt for low-nickel variants. For allergy sufferers, there are special, nickel-free options.
For a greener future
Although the production of stainless steel is more energy-intensive than that of plastic, the material scores with sustainability through durability. Choosing stainless steel can thus be a step towards a more environmentally friendly lifestyle.
What about lunch boxes for kids?
The same steel, in smaller sizes. The 27 oz box holds a school lunch, and the latch is easy to work for small hands.
Parents usually ask two things. Is it safe? Independently tested for lead under the US CPSIA — the report is on our certificates page. And how does it not get lost? A name, engraved into the steel. Twenty bags on the same hook, and only one has her name on it.
For school and daycare picks, see the kids collection — or jump straight to back to school.
Our verdict: who should buy one, and who should not
If you reheat your lunch in a microwave every day, a glass container will serve you better. For everyone else — commutes, office desks, hikes and hot ovens — the pros clearly outweigh the cons. If that sounds like you, start with the leak-proof bento lunch box or browse all stainless steel lunch boxes to find your size.
