Bento Boxes have recently gained popularity in every part of the world as one of the convenient tableware items. Be it for students, office workers, or travelers, the bento boxes turn out to be ideal while carrying food in everyday life. Whatever people demand in bento boxes, it is not just about portability but also how to keep the food hot.
So, does bento box really keep food warm? Which provides better heat preservation performance: a stainless steel or plastic bento box? Let’s find out together.
Stainless Steel Bento Box: Excellent in Heat Preservation
The main characteristics of the stainless steel bento lunch box are that it is durable and has a very good heat preservation effect. Due to the nature of the properties, stainless steel itself is a kind of metal that has good thermal conductivity; after conducting high-temperature treatment, it is able to keep food hot for a longer period of time. Following are major advantages of using a stainless steel bento box:
- Better preservation of temperature: Most of the designs for stainless steel bento lunch boxes have a double-layered structure with a middle insulation layer, which can keep the food warm for a long time. With this kind of design, it is quite suitable for hot foods, like rice, stir-fries, or soup.
- Durability: Stainless steel is resistant to drops and corrosion; with reasonable care, therefore, it should last daily use and uses which require frequent carrying of food, such as picnics and work lunches, etc.
- Легко чистить: Most of the stainless steel bento containers can be washed up easily by hand or in a dishwasher.
- On the other hand, the disadvantage of the stainless steel Bento Boxes is that they are usually a bit heavier compared to plastic boxes, and that could be the reason why they will not be suitable for those people that emphasize more on the portability of the lunch box.
Plastic Bento Boxes: Light and Versatile
Plastic bento boxes have relative advantages in weight and portability compared to stainless steel bento boxes. Compared to the bento lunch box made of stainless steel, they are generally lighter and have more varieties in design, rich colors, and patterns that appeal most to children and youth.
- Lightweight and Portable: Made of plastic material, the lunch box is lightweight and ideal for small bentos or lunches that have to carry several foods.
- Multicompartment design: Most of the plastic bento containers have compartmentalization, hence making it easy to separate different types of food without mixing and to keep fresh.
- Safe heating: Some plastic bento boxes can be put directly in the microwave for heating, hence saving extra containers to heat.
However, plastic lunch boxes still can’t compete with stainless steel in performance in terms of heat retention capability. While they can keep the food warm for a very brief period of time, the temperature will dissipate sooner because of the lack of the double-layer insulation design. So, in case you want the food to stay hot for a long period of time, you may want to add some extra insulation sleeve or container to retain the temperature.
How to Choose the Right Bento Box?
Whether you go for a stainless steel lunch box or plastic depends upon the usage scenario and thus your requirements. If you want your food to stay longer and you do not mind carrying a little weightier lunch box, then go for a stainless steel lunch box. If you pay more attention to lightness and being easy to carry, or need a lunch box that can be heated directly in the microwave, then the plastic lunch box will be more suitable.
