What is the principle of color change for temperature sensing labels?
The color changing principle of temperature sensitive stickers is mainly based on the color change characteristics of temperature sensitive materials. This material can undergo chemical and physical changes at different temperatures, leading to changes in molecular structure and causing a change in the color of reflected light. Specifically, the color change form of temperature sensitive stickers can be low-temperature colored, high-temperature colorless, or low-temperature one color, high-temperature another color, and this change can be reversible. For example, in some temperature sensitive stickers, when the temperature reaches or exceeds a specific value, the color of the sticker will change, indicating the temperature change intuitively. This principle makes temperature sensitive stickers widely applicable in fields such as temperature monitoring and safety warning.
It should be noted that the color changing principle of temperature sensitive stickers may vary depending on the material formula and manufacturing process, but overall they are based on the color change characteristics of temperature sensitive materials. In addition, the use of temperature sensitive stickers should follow product instructions and safety regulations to ensure their accuracy and safety.
How accurate is the temperature measurement with temperature sensing stickers?
The accuracy of temperature measurement with temperature sensing stickers varies depending on factors such as product type, usage, and environment. Generally speaking, disposable temperature stickers in daily life have relatively poor temperature perception ability and are mainly used for quick and rough temperature judgments. Specialized temperature sensitive stickers used in fields such as electricity and railways have high precision in grasping temperature.
The real-time temperature sensing effect of temperature sensitive stickers is affected by the interference of the surrounding environment, and their temperature measurement ability is usually improved when used in enclosed spaces. In contrast, temperature sensitive stickers used outdoors have relatively poor temperature observation due to the complex and variable environment. Therefore, when using temperature sensitive stickers, it may be necessary to conduct comprehensive testing by combining multiple temperature sensitive stickers to improve the accuracy of temperature measurement.
The selection of temperature sensitive stickers is also crucial. Temperature sensitive stickers of different specifications and materials may have different temperature sensing abilities, so users should choose suitable temperature sensitive sticker products according to their actual needs. At the same time, for situations that require high-precision temperature measurement, it is recommended to use non-contact thermometers and other equipment for comprehensive temperature measurement to ensure the accuracy of the measurement results.
Water soluble paper label
Water soluble paper label, as its name suggests, dissolves in water. Glue and facial paper are extracted from starch and made from starch, which quickly dissolves in water, making it a high-end environmentally friendly label. Stick it on a food tray or storage container to clearly indicate the product name and date. It can be quickly and thoroughly dissolved in water during the washing process.
Water soluble paper labels are used as tableware labels, and the paper surface material is based on starch and does not contain wood fibers. Used as a food label, no special cleaning is required. The adhesive and label are completely dissolved in hot or cold water, leaving no sticky residue. It has advantages such as speed, cleanliness, convenience, energy conservation, water conservation, and environmental friendliness.
This type of label ensures food safety: it can dissolve in water at any temperature, including dishwashers. Microwave safety: sized to fit all storage containers.
Additionally, it should be noted that water-soluble paper labels are highly sensitive to moisture, relative humidity, and temperature. Exposure to environmental conditions higher than recommended will accelerate degradation and decomposition. Especially suitable for beer labels, tableware, fruit and other information labels. After washing with water, the product does not leave any adhesive marks.
What is a water solubility label
Water soluble label, as the name suggests, is a type of label material that dissolves upon contact with water. Its glue and dough are extracted from starch, so it can quickly dissolve in water, making it a high-end environmentally friendly label. This type of label is particularly suitable for information identification of food, tableware, fruits, etc. After being attached to food trays or storage containers, it can quickly and thoroughly dissolve in water during the washing process, without the need for special cleaning and leaving no sticky residue.
The advantage of water-soluble labels lies in their easy cleaning and rapid dissolution characteristics, which help save energy and water resources while meeting environmental requirements. However, it should be noted that water solubility labels are highly sensitive to moisture, humidity, and temperature. When storing, exposure to environmental conditions higher than recommended should be avoided to prevent accelerated degradation and decomposition.
