lunch box

As the saying goes, "diseases come from the mouth." Choosing a high-quality food container can effectively improve the quality of life and safety. Stainless steel lunch boxes have become the first choice for many people because of their durability, environmental protection and easy cleaning.

Whether it is storing leftovers in the refrigerator, putting fruits on a plate, or bringing food by office workers, students, and travelers, stainless steel lunch boxes are very practical.

Material selection and development of metal lunch boxes

In addition to stainless steel, the early metal bento boxes also have aluminum lunch boxes, but aluminum products will release some harmful substances during the heating process of food, and if the food is stored in an aluminum lunch box for a long time, aluminum ions may penetrate into the food.

Therefore, aluminum lunch boxes have basically withdrawn from the stage of history, and metal lunch boxes are mainly stainless steel lunch boxes.

How to choose a stainless steel lunch box

The common stainless steel lunch boxes in the current market are mainly composed of 304 and 316 materials. We can first say the conclusion and then compare the differences between the two.

Conclusion: If you pursue quality, choose 316 material, if you pursue cost-effectiveness, choose 304 material.

Comparative characteristics of 304 and 316 stainless steel:

Corrosion resistance: 304 is the most common stainless steel with good corrosion resistance, but it is not as good as 316 stainless steel in some chlorine-containing environments, such as seawater, chemicals, etc. Corresponding to the application scenarios in real life, such as swimming pools, outdoor camping or storing things with high salt content, 316 is worse than 304 stainless steel.

Mechanical properties and economic performance: 304 stainless steel has good toughness and high strength performance, and the cost is lower than 316 and it is easier to process, so it is widely used in tableware, kitchenware, lunch boxes, and food processing equipment.

Heat resistance: 316 stainless steel is more resistant to high temperatures than 304, and is suitable for environments where food is often processed at high temperatures. Although 304 is also resistant to high temperatures, it will have a certain impact if long-term high temperatures are required. Usually 316 stainless steel is more used in biotechnology, pharmaceuticals, medical accessories and food processing industries, which have higher requirements for health and hygiene and more demanding environments.

Suggestions for choosing stainless steel lunch boxes

For most users, 304 stainless steel lunch boxes can already meet daily use needs, whether it is an ordinary family or office environment or school daily life, 304 stainless steel is durable and corrosion-resistant while the price is relatively reasonable.

But if you are in a special environment, such as outdoor camping, travel enthusiasts, high-salt environment, long-term heating of food, choose 316 material.

And stainless steel lunch boxes can be reused, reducing the loss of disposable tableware, reducing environmental pollution, and stainless steel will not release harmful chemicals into food, which is a healthy and environmentally friendly choice.

Cleaning and maintenance of stainless steel lunch boxes

Whether you choose 304 or 316 stainless steel lunch boxes, they need regular cleaning and maintenance, which can not only keep healthy but also extend the service life. It is recommended to use mild detergent and soft cloth for cleaning, and avoid using hard objects such as steel wool to scratch the surface and cause unnecessary damage. In addition, try not to store strongly acidic or alkaline foods for a long time to prevent corrosion.

Why choose HY
