Pressure-sensitive labels, also known as self-adhesive labels, have become a popular choice in the labeling industry. These labels are produced through a process called die cutting, which involves cutting label paper in a laminate composition. The composition consists of label paper, pressure-sensitive adhesive, release coating, and base paper.

Die cutting is a crucial step in the production of pressure-sensitive labels. It requires the label paper to have an exact caliber, allowing the cutting tool to penetrate the label fully without cutting into the base paper. After the die cutting process, the grid between the labels is torn off, requiring precise cutting. Therefore, the thickness profile of the base paper plays a significant role in the overall quality of the labels.

Labeling machines play a crucial role in the application of pressure-sensitive labels. These machines must accurately detect the position of the label to ensure it is placed correctly on the goods being labeled. One common method for detecting the label’s position is through the use of photocells, which can read the position through the paper. To enable this process, the label backing paper must have a sufficient degree of transparency. Most label backing papers used in pressure-sensitive labels are of the glassine type, with a basis weight of around 60 g/m2.

The use of pressure-sensitive labels offers numerous advantages in various industries. Firstly, their self-adhesive nature eliminates the need for additional adhesives or glue, making the labeling process more efficient. Additionally, pressure-sensitive labels can be easily applied to different surfaces, including glass, plastic, metal, and cardboard. This versatility makes them suitable for a wide range of products and packaging materials.

Moreover, pressure-sensitive labels are available in various shapes, sizes, and designs, allowing businesses to create customized labels that reflect their brand identity. The labels can be printed with high-quality graphics and text, enhancing the visual appeal of the products and helping to attract consumers.

Furthermore, the durability of pressure-sensitive labels is worth noting. These labels are designed to withstand various environmental conditions, including moisture, heat, and cold. This ensures that the labels remain intact and legible throughout the lifespan of the product, contributing to a positive customer experience.

In conclusion, pressure-sensitive labels have revolutionized the labeling industry with their ease of application, versatility, and durability. The die cutting process and the quality of the base paper are crucial for producing high-quality labels. With advancements in technology and design capabilities, pressure-sensitive labels continue to be a popular choice for businesses looking to enhance their product packaging and brand image.
