Smart breast milk storage / Smart breast milk storage

We have created a milk storage bag that directly determines whether the stored breast milk has deteriorated and whether the temperature of breast milk heating is appropriate.
Using a special material such as color changing ink, this material has the following two characteristics: it can become a specific color after a certain period of time and display a specific color at a specific temperature.
Add the material to the lid and outer packaging of the breast milk storage bag, and judge the color change directly.Such a breast milk storage bag is more intuitive, convenient for the parents' life, and also provides quality breast milk for babies.
