Thermoadhesive Label Embossed Graphic Effects Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermoadhesive labels with embossed graphic effects face limitations in flexibility and cost due to the need for machine-made metal drums and lengthy, expensive manufacturing processes, which restrict the variety of textures and increase production costs.
Innovation Solution
A thermoadhesive label with a catalysed silicon embossed portion and a polymeric layer made of non-catalysed, non-cross-linked single-component polyurethane resin, allowing for silk-screen printing and drying to create embossed patterns and textures, reducing manufacturing complexity and costs while enhancing tactile perception and ecological compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If machine-made metal drums with engraved patterns are used to create embossed effects, then graphic/texture effects can be reproduced, but manufacturing flexibility is lost and costs increase due to the need to absorb machining costs over large production quantities
Solution Approach 1:
The patent replaces expensive, complex metal drum machining with a simple silicone rubber stamp that can be easily copied and modified. The stamp captures the embossed pattern through a simple pressing action against the label material, eliminating the need for expensive metal machining operations while maintaining production flexibility for different designs
Solution Approach 2:
The patent uses inexpensive silicone rubber stamps that can be easily replaced or modified for different designs, replacing expensive, durable metal drums. This allows for cost-effective production runs of various sizes without the need to absorb high upfront machining costs, enabling small batches and design changes economically
2Strength
If cross-linked polymeric layers are used, then adhesion strength is improved, but tactile perceptibility of texture is reduced and the transfer becomes harder
Solution Approach 1:
The patent modifies the polymeric layer composition by incorporating plasticizers and specific polymer blends that maintain adhesion strength while reducing cross-linking density. This chemical parameter change allows the material to remain softer and more tactilely perceptible while still providing sufficient bonding strength for the label application
