Stainless Steel Vacuum Insulated Lunch Box

Stainless steel vacuum insulated lunch boxes are one of the most popular choices on the market.

Whether it is hot soup, fried rice or hot dishes, they can stay warm for a long time. The high-quality vacuum insulation technology ensures that the food is hot and can be kept hot for more than 4-6 hours, which is suitable for employees or students.

Advantages of Stainless Steel Insulated Lunch Box

Long-lasting heat preservation: Vacuum technology can keep the temperature of food unchanged for a long time, suitable for long-term use outside.

Strong durability: Stainless steel has excellent durability and oxidation resistance, long service life, and is resistant to falling and wear, and can withstand long-term daily use.

Safe and healthy: Stainless steel is a food-grade material and is not easy to react with food, keeping the original flavor of food, ensuring non-toxicity and harmlessness, and protecting health.

Thermal Insulation Effect

Due to the efficient insulation performance of its vacuum layer, the stainless steel vacuum insulated lunch box can effectively maintain the temperature of food for up to 4-6 hours, especially suitable for long-term use outside. Hot soup, fried rice and hot dishes can all be kept warm and not easy to cool down.

Electric Heated Lunch Box

Electric lunch boxes have built-in heating elements, which are suitable for users who need to heat up food at noon. Simply plug in the power supply and the electric lunch box can quickly heat the food to a suitable temperature for consumption. Many electric lunch boxes not only have a heating function, but also a heat preservation function, which can maintain the temperature after heating is completed, making them suitable for use in the office, school or car.
