Materials and Structural Design: The Technological Core of Multi-Layer Composite Labels
The core of multi-layer composite labels lies in the multi-layer lamination process. The face material is made of synthetic paper, possessing water and oil resistance, and its surface can be printed with adhesive. The middle layer is a transparent OPP film, providing tensile support (tensile strength 0.1~0.8MPa, elongation 0.5%), ensuring the label is not easily deformed when bent or squeezed. The backing paper uses white glassine paper, combined with water-based adhesive (environmentally friendly reinforced adhesive), balancing adhesion and environmental requirements. The total material thickness is controlled at 0.103mm, maintaining flexibility while meeting the precision requirements of automated labeling equipment (such as compatibility with G-220A printers).
Functionality: An Upgrade from Labeling to Information Management
These labels achieve high-precision image and text reproduction through letterpress printing technology, supporting multilingual information presentation and meeting international regulatory requirements such as the GHS standard for pesticides. The comprehensive anti-counterfeiting system integrates lamination, hot stamping, and embossing processes, such as enhancing visual recognition through local UV technology or using the multi-layer label structure to hide anti-counterfeiting codes. Its long-term temperature resistance reaches -15℃, making it suitable for cold chain transportation or extreme storage environments. Furthermore, the colorful, irregularly shaped label design breaks through the traditional rectangular limitations, achieving a perfect fit to the bottle through die-cutting, enhancing the overall aesthetics of the packaging.
Application Scenarios: Cross-Industry Solutions
In the pharmaceutical field, multi-layer labels are commonly used for integrating drug instructions, folding multiple pages of information into a single label to save packaging space; the cosmetics industry utilizes its hot stamping process to enhance brand recognition; pesticide packaging must comply with GHS classification standards, using a multi-layer structure to distinguish hazard symbols from usage instructions; daily chemical product labels focus on abrasion resistance and water resistance, ensuring clear readability in humid environments. Special processes such as adhesive printing can hide information on the back of the label, revealing it only at specific angles or under certain lighting conditions, enhancing information security.
