Security Label With Partial Metal Layer For Tamper Evidence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security labels lack sufficient counterfeit security measures, as their visual appearance changes irreversibly upon opening, and there is a need to enhance their tamper evidence and visual value.
Innovation Solution
A security label with a partially applied metal layer in register with a first functional layer, combined with multiple color layers and adhesion-controlling layers, which increases the complexity of reproduction and provides enhanced tamper evidence and visual security features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal layer is partially applied along the carrier film and arranged in register with the first functional layer, then counterfeit security and visual value are increased, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The metal layer is applied only in specific areas rather than covering the entire carrier film, creating distinct functional zones that enhance security features while managing complexity
Solution Approach 2:
The metal layer is strategically positioned in register with the first functional layer to create localized optical effects and security features, providing enhanced counterfeit protection where most needed
2Illumination intensity
If a metal layer is partially applied along the carrier film and arranged in register with the first functional layer, then visual value is increased due to metallic sheen, but manufacturing complexity increases
Solution Approach 1:
The metal layer is applied in register with the first functional layer during the manufacturing process, ensuring precise alignment and optical effects are achieved in the initial production stage rather than requiring post-manufacturing adjustments
3Reliability
If multiple layers including metal layer, color layers, and functional layers are applied, then tamper evidence is enhanced, but production process complexity increases
Solution Approach 1:
Multiple layers including the metal layer, first and second color layers, and first and second functional layers are combined in a single integrated structure applied to the carrier film, achieving enhanced tamper evidence through layer interactions while managing production through unified application processes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The security label offers increased counterfeit security and visual value due to the metallic sheen and complex production process, making it difficult to replicate while maintaining a clear break-open mechanism.
Implementation Method 1
The light is partially reflected by the metal layer at the interface to the next layer
Implementation Method 2
the refractive effect of the optically active structure is visible to the viewer
