Description
Technical Field
The invention relates to the field of labels, in particular to a temperature sensing label.
Background
In recent years, with the increasing quality of life, the freshness of daily necessities, food safety and the like are receiving more and more attention, and more goods with high temperature requirements need to be transported and stored, such as seasonal fruits and vegetables, imported goods and the like. Some goods with high temperature requirements, such as food, medicine, etc. that need to be frozen or refrigerated, will degrade and even spoil or fail completely once a certain temperature is reached or exceeded. How to make consumers fully understand the temperature change of goods in transportation and storage is a major research focus.
At present, a dye called "visible temperature pigment", "temperature measuring pigment" or "thermal color" is developed, which is a particulate dye that changes color according to temperature. The temperature-dependent paint is divided into inorganic pigment and organic pigment. There are two kinds of products, one is to change color after heating, one is to return to original color after reducing, and the other is not to add reverse. If reversible, temperature-dependent coatings are combined, the process of changing to multiple colors at elevated temperatures can be seen visually. In addition, in general, when transparent or black-colored, the temperature-sensitive film coating material is colored only in a specific temperature range. Most substances have no color change, but some substances are made according to the principle of changing color by temperature, ultraviolet light or acidity, pressure or moisture, conduction and non-electrification. If the contents or combination of the components of the organic compound are changed, the temperature is increased or decreased, and the original color is not present or the opposite color is lost.
There is a pressing need to develop new more intuitive tags that sense temperature changes more efficiently.
