Why do we choose stainless steel?

There are many types of materials for lunch boxes on the market, which can be roughly divided into the following categories: plastic, ceramic, glass and metal. Different materials have their own advantages, and the scenarios and target groups for their use are also different. At the same time, due to the increasingly strict environmental regulations worldwide, restrictions on plastic have been continuously tightened. The advantages of metal packaging, such as recyclability and reusability, have made it an important choice for environmentally friendly materials.

Nowadays, the main metal material refers to stainless steel. In the past, there were aluminum containers, but aluminum products can release harmful substances during food heating, and aluminum ions may seep into food if food is stored in aluminum containers for a long time. Therefore, aluminum containers have been phased out. The current metal bento lunch boxes mainly refer to stainless steel.

As the saying goes, "Disease enters through the mouth." Therefore, a high-quality food container can significantly and effectively improve food safety and quality of life. Whether it is storing food in the refrigerator or carrying food for students, office workers, and travelers, thermos lunch boxes are very practical and essential storage containers. For users who need to carry and transport food, we recommend choosing metal materials first, which can effectively reduce the risk of leakage, breakage, and transportation losses.

Common types of stainless steel materials

Currently, the common high-quality stainless steel kids lunch box on the market are mainly made of 304 and 316 materials. We can draw a conclusion first and then compare the specific differences between these two materials. Simply put, 316 material has better quality, while 304 has a higher cost performance. In terms of chemical properties, 304 material has poorer corrosion resistance in all environments containing chlorine, such as seawater and chemicals, compared to 316 material. However, as an insulated lunch box, its main application scenarios focus on some common life scenarios, such as swimming pools, outdoor camping, or storing high-salt items. In these cases, the corrosion resistance of 304 is better than that of 316. At the same time, the cost of 304 is lower than that of 316 material, and 304 is easier to process, so it is widely used in tableware, kitchenware, lunch boxes, and food processing equipment, making it a cost-effective choice.

316 material performs better in high-temperature environments and is suitable for environments where food is frequently processed at high temperatures. Although 304 is also heat-resistant, long-term and prolonged high-temperature processing can affect its performance. Therefore, 316 material is more commonly used in high-end quality industries such as biology, pharmaceuticals, and medical fields. The lunch boxes made of 316 material have better quality but are also more expensive.

Based on the above characteristics, stainless steel lunch boxes can meet the daily usage needs. Whether for ordinary families, offices, or schools, 304 is relatively reasonable in price and durable. However, if you are in special environments, such as outdoor camping, long-distance travel, or prolonged heating of food, we recommend choosing 316 material.
