Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biodegradable films are incompatible with corrosive ingredients in tobacco and pharmaceutical products, and conventional anti-counterfeiting techniques are cumbersome and aesthetically unappealing.
Innovation Solution
A multilayer polymeric composite with an iridescent non-metallic holographic stereogram is used, coated with a primer and UV base coat, to create an anti-counterfeit, biodegradable, and compostable packaging material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional metalized films are used for anti-counterfeiting, then anti-counterfeit capability is improved, but device complexity and aesthetic appeal deteriorate
Solution Approach 1:
The patent applies iridescent holographic stereograms that exhibit color changes and optical effects to provide anti-counterfeit capability. This replaces conventional metalized films with a more aesthetic and less cumbersome solution that displays iridescent colors and holographic images depending on viewing angle, thereby improving aesthetic appeal while maintaining security features.
Solution Approach 2:
The patent uses composite packaging material comprising multiple layers including biodegradable polymer layers and holographic stereogram layers. This composite structure integrates anti-counterfeit functionality with environmental sustainability, combining the benefits of biodegradability with advanced optical security features in a unified packaging system.
2Object-generated harmful factors
If biodegradable polymeric films are used, then environmental friendliness is improved, but compatibility with corrosive ingredients deteriorates
Solution Approach 1:
The patent employs composite packaging structures where biodegradable polymer layers are combined with other functional layers including holographic stereograms and barrier layers. This composite approach allows the biodegradable components to provide environmental friendliness while the overall composite structure ensures compatibility with corrosive ingredients through appropriate layer selection and configuration.
Solution Approach 2:
The patent applies different material properties to different layers of the packaging structure. The biodegradable polymer provides environmental friendliness in specific layers, while other layers provide barrier properties and chemical compatibility. This local differentiation of material qualities allows each layer to perform its specific function optimally without compromising overall package integrity.
