The sterilization principle of high-temperature sterilization indicator labels
High-temperature sterilization indicator labels, also known as thermal indicator labels, are important tools widely used in medical, pharmaceutical, and biological laboratory fields. These labels are typically made from a special type of thermally sensitive material that changes color when exposed to specific high-temperature environments, thereby indicating whether the sterilization process has been completed. This article will delve into the working principle of high-temperature sterilization indicator labels and their applications in various fields.
The core working principle of high-temperature sterilization indicator labels is based on the color-changing properties of thermally sensitive materials. These thermally sensitive materials are usually composed of one or more chemical substances that undergo chemical reactions at specific temperatures, leading to color changes. This color change is typically irreversible, so once the label changes color, it is clear that the sterilization process has been completed.
Sterilization color changing label
In today's packaging industry, the application of sterilization color-changing labels is receiving increasing attention. These labels not only provide effective sterilization protection but also indicate the sterilization status of packaging through color changes, offering consumers safer and more reliable packaging products.
Sterilization color-changing labels utilize special chemical reaction technology. When sterilization treatment is applied to the packaging, the label changes color based on the concentration and duration of the sterilizing agent. This color change effectively alerts operators to the sterilization status of the packaging, preventing incomplete or excessive sterilization due to human factors.
The advantages of sterilization color changing labels
-
Improving production efficiency: By indicating the sterilization status of packaging through color changes, it can reduce the time and cost of manual inspections, thereby improving production efficiency.
-
Enhancing product quality: Sterilization color-changing labels can effectively monitor the sterilization status of packaging, ensuring that products will not be contaminated by microorganisms during their shelf life, thus enhancing product quality.
-
Boosting consumer confidence: Consumers can judge the safety and reliability of products by observing the sterilization color-changing labels on the packaging, thereby boosting their confidence.
-
Facilitating regulatory supervision: Regulatory authorities can assess the sterilization status of products by checking the sterilization color-changing labels on the packaging, making it easier for them to conduct supervision and inspections.
Steam sterilization packaging label
Steam sterilization packaging labels are indicators used to show that a product has been treated with steam sterilization. They are typically made with crepe paper or label paper as the base material, coated with color-changing ink as the sterilization indicator, and backed with pressure-sensitive adhesive. When certain sterilization conditions are met (such as 121℃ for 20 minutes or 132℃ for 3 minutes), the chemical indicator stripes on the crepe paper base will change from light yellow to black. The main function of steam sterilization packaging labels is to indicate that the product has been steam sterilized, ensuring its hygiene and safety. Additionally, steam sterilization packaging labels can also provide relevant product information, such as the production date and shelf life, helping consumers make correct choices and use the product properly.
Radiation sterilization instruction label
The irradiation sterilization color-changing indicator label is a circular label with a diameter of 13mm, used as an indicator for whether irradiation sterilization products have been exposed and whether the dose has reached the required level. Compared to similar types of indicator labels, its larger diameter makes it more eye-catching and easier to identify.
Before irradiation sterilization, the yellow label is attached to the outer packaging of the product. After the irradiation dose reaches the corresponding requirement, it changes to a bright red color. The color starts to change at 4kGy, and as the dose increases, the red color gradually deepens.
There are 5000 labels per roll, and customized production is also available according to user requirements.
