What is a lunch box?
The lunch box keeps the heat like a thermos of water. If the thermos is used to keep the water hot, the lunch box is used to keep the rice and food hot.
The lunch box has a design similar to a regular box but is made up of 3 layers. In particular, the inner and outer layers are usually made from PP plastic or stainless steel. In the middle of the two layers is a vacuum with no insulation effect.
The lunch box keeps warm without using electricity. All you need to do is prepare delicious food, put it in a box, and close the lid. Depending on the type of heat box you use will effectively keep food warm for 4 – 8 hours. To choose the best heat preservation box product, you need to find out carefully.
Criteria for choosing the best lunch box
Currently, the market has a lot of types of heat-retaining lunch boxes with diverse prices. Therefore, to choose the best heat preservation box, you should base on the following criteria:
1. Capacity to keep the lunch box heat
That is the first thing to learn, of course. Because each type of heat preservation box will have a different capacity, depending on your needs, choose a box of rice with the most suitable capacity.
The capacity of the lunch box will determine the capacity and level of food storage. Accordingly, the box of rice holds heat with many floors; many compartments will help you hold more food. For example, a 3-story lunch box allows you to store more food and is more convenient.
Therefore, consider based on your daily intake and menu and choose the appropriate lunch box capacity. You can choose a slightly larger box so you can put more food when you need it. Ideally, it would help if you chose a lunch box with a capacity of over 1 liter.
2. Material of plastic or stainless steel lunch box core
When buying a thermos box, this is the top concern. The core material of the lunch box will directly affect your health and the ability to retain the heat of the product. Commercially available lunchbox products are often made from uncertain materials. That makes the ability to retain heat poorly, affecting health.
Genuine thermos lunch box products are made of two basic materials: 304 stainless steel or stainless steel and PP plastic.
With a core box made from 304 stainless steel, there is no question of quality. This type of lunchbox has good heat retention, strength, and impact resistance. Especially, it is completely safe for health, and also very easy to clean. However, these types of lunch boxes made of this material are often quite expensive.
While the core of a lunch box is made of plastic, it is cheaper. When it comes to the plastic core, many people probably think of its impact on health. However, only low-quality plastic is like that. What about genuine lunch boxes, whose core is made from PP plastic that does not contain BPA, will be very safe. Therefore, when buying this type of lunch box, you need to find out carefully.
3. Number of box compartments
Many box compartments are usually proportional to capacity. Accordingly, the capacity of the big box will have more compartments.
Multi-layered lunch boxes have a more ergonomic and ergonomic design. These types usually have a large outer box used to hold smaller food containers. You can divide food clearly into each compartment without fear of being mixed in the process of moving.
4. Heat holding time
When choosing to buy a box of heat preservation, of course, you cannot ignore the heat retention factor of the product. Depending on the type of box, the material will have different retention times. Types of heat-resistant lunchboxes that use vacuum insulation technology will have a better retention time. Some high-end thermostatic lunch boxes can hold up to 8 hours of heat. Therefore, it is very suitable for students, office workers or far trips.
