Dual-faced labeling system with patterned release regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional shelf tags are costly, environmentally unfriendly, and cumbersome to affix and remove, with significant waste generated from silicone-coated paper release liners and moisture imbalances in refrigerated or frozen environments, limiting their effectiveness and efficiency.
Innovation Solution
A dual-faced labeling system using two substrates with adhesive-coated and release regions, allowing for releasable adhesion and eliminating the need for separate silicone-coated release liners, which can be repulpable and applied in patterns to reduce waste and improve handling and adhesion properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If traditional shelf tags with silicone-coated paper release liners are used, then adhesion can be achieved, but significant waste is generated and environmental harm increases
Solution Approach 1:
The patent extracts and eliminates the silicone-coated paper release liner from the traditional shelf tag system. By using a dual-faced substrate where one side serves as the adhesive backing for the label and the other side serves as the release surface, the separate release liner is removed entirely, preventing waste and environmental harm associated with its disposal.
Solution Approach 2:
The patent merges the substrate and release liner into a single dual-faced substrate structure. The back side of the substrate itself provides the release surface for the adhesive, eliminating the need for a separate release liner component. This consolidation reduces material usage and waste generation.
2Quantity of substance
If silicone-coated paper release liners are used, then label adhesion can be maintained, but label density decreases and freight costs increase
Solution Approach 1:
By combining the substrate and release liner into a single dual-faced substrate, the overall thickness and volume of each label unit is reduced. This increases the number of labels that can be stored and transported per unit volume, thereby increasing label density and reducing freight costs.
3Reliability
If traditional adhesive systems are used in refrigerated or frozen environments, then adhesion can be achieved, but moisture imbalance causes curling and reliability decreases
Solution Approach 1:
The patent employs a composite dual-faced substrate structure with specific material properties that maintain moisture balance in cold environments. The substrate materials are selected to resist moisture absorption and expansion/contraction that would cause curling, ensuring adhesion reliability in refrigerated and frozen conditions.

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 dual-faced labeling system reduces waste, increases label density, lowers freight costs, and prevents moisture-related curl issues, providing a more efficient and environmentally responsible solution for in-store promotions while maintaining effective adhesion and ease of use.
Implementation Method 1
The first adhesive-coated region is releasably adhered the second release region and the second adhesive-coated region is releasably adhered to the first release region

AI summary
A method includes applying a release formulation to a first substrate, wherein the release formulation is applied to a first portion of the first substrate leaving a second portion of the first substrate without the release formulation; applying the release formulation to a second substrate, wherein the release formulation is applied to a second portion of the second substrate leaving a first portion of the second substrate without the release formulation; applying an adhesive to the first substrate, wherein the adhesive covers at least a part of the first portion of the first substrate and at least a part of the second portion of the first substrate; and laminating the first substrate to the second substrate to form a laminated article; wherein the laminated article is configured to transfer the adhesive on the first portion of the first substrate to the first portion of the second substrate upon separation of the first substrate from the second substrate.
