Solution Overview
Problem
Conventional adhesive duplex shipping labels generate significant liner waste and are inefficient in application, with complex constructions that cause printing complications and equipment issues during automated labeling processes.
Innovation Solution
A linerless duplex label system featuring an unfolded single label ply with an adhesive layer applied along the border, allowing for flat adhesion to packages and enabling removable adhesion between labels, reducing waste and improving application efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional adhesive duplex shipping labels are used with a liner, then the label can be easily stored and handled, but significant liner waste is generated and the application process becomes inefficient
Solution Approach 1:
The invention extracts and removes the liner component from the label system entirely. The linerless label stock consists only of the label material itself with adhesive applied to one side, eliminating the need for a separate liner that would otherwise be discarded after use. This directly addresses the contradiction by removing the source of waste while maintaining label functionality.
Solution Approach 2:
The linerless label design allows the label material itself to serve the functions previously performed by the liner (providing a backing for storage and handling). The label stock is designed to be self-sufficient without requiring a separate liner component, thereby eliminating waste while preserving ease of operation.
2Ease of manufacture
If conventional adhesive duplex shipping labels with liners are used, then labels can be stored in rolled form, but the liner is problematic to remove using automated label printing and application equipment
Solution Approach 1:
The invention removes the liner component that causes problems in automated processing. By eliminating the liner entirely, the label construction is simplified to just the label material with adhesive, removing the complexity of coordinating liner and label movements in automated equipment while maintaining ease of manufacture through simpler material handling.
Solution Approach 2:
Instead of having a liner with a label attached to it (conventional approach), the invention inverts the relationship by having a label with adhesive directly on the label material without a liner. This fundamental reconfiguration simplifies automated processing by eliminating the need to manage liner removal and coordination.
3Stability of the object's composition
If traditional duplex labels with retained liner portions are used, then the label maintains structural integrity, but the construction becomes complex and presents a thick profile that causes printing complications
Solution Approach 1:
The invention extracts the excess liner material that creates structural complexity and thickness. By using only the necessary label material with adhesive applied to the appropriate side, the label achieves structural integrity through proper adhesive bonding rather than through multiple layers of liner and label material, thereby simplifying construction and eliminating printing complications.
Solution Approach 2:
The invention applies adhesive locally to specific areas of the label material rather than requiring extensive liner coverage. This localized approach to adhesion provides sufficient structural integrity and stability while minimizing material usage and construction complexity, allowing for thinner, more printable labels.
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 linerless duplex label system minimizes waste, simplifies the labeling process, and enhances printing efficiency by eliminating the need for liners, while maintaining secure adhesion and hiding sensitive information until needed.
Implementation Method 1
an adhesive layer applied to the bottom face of the single label ply along the border portion of the single label ply, with the border portion of the single label ply operable to be flatly adhered to the package by the adhesive layer
Implementation Method 2
The adhesive layer permits removable adhesion of overlaid linerless duplex labels to one another by adhering the top face of one label to the bottom face of another label

AI summary
A linerless duplex label system is operable to print and apply a linerless duplex label to a substrate. A plurality of linerless duplex labels are provided and each label includes a single-ply stock with top and bottom faces. The label also includes an endless adhesive border applied to the bottom face. The label is configured so that multiple labels can be removably adhered to each other by the adhesive border, with at least one linerless duplex label being removably overlaid onto at least one other duplex label.
