Linerless Multi-Part Label Systems for Simultaneous Carton Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current labeling methods for applying packing lists and shipping labels to sealed cartons are inefficient, requiring precise timing, multiple printers and applicators, and significant space, and often result in mismatches between labels.
Innovation Solution
A system comprising a carrier material with an upper and lower label, where the upper label has a removable segment and the lower label has a removable region, both with reduced adhesive zones, allowing sequential dispensing and alignment on a label applicator, enabling simultaneous application without the need for precise timing or multiple equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate packing list labels and shipping labels are applied using multiple printers and applicators, then label application can be performed, but device complexity and floor space requirements increase significantly
Solution Approach 1:
The patent combines multiple label types (packing list label and shipping label) into a single integrated label structure. The packing list label and shipping label are positioned adjacent to each other on the same carrier sheet, allowing both to be applied simultaneously by a single label applicator, thereby reducing device complexity and floor space requirements while maintaining the capability to apply both labels.
2Ease of manufacture
If separate packing list labels and shipping labels are applied using multiple applicators, then label application can be performed, but precise timing control is required to avoid mismatches
Solution Approach 1:
By integrating multiple labels on a single carrier sheet, the patent eliminates the need for multiple applicators operating in sequence. The single applicator applies the entire multi-label structure simultaneously, removing the timing synchronization requirement entirely and preventing mismatches between packing list and shipping label applications.
3Loss of information
If packing list information is concealed until delivery, then information security is maintained, but label structure complexity increases
Solution Approach 1:
The patent implements a nested label structure where the shipping label is positioned over the packing list label, creating a layered configuration. The shipping label acts as a cover that conceals the packing list information underneath, maintaining information security until the shipping label is removed at delivery. This nested arrangement achieves concealment without requiring complex additional structures.

AI summary
Multi-part label systems, and methods for their assembly. A linerless label roll separable into at least a first label and a second label is provided. The first label and second label are dispensed from the linerless label roll and applied to a surface simultaneously, whereby after application the underside of the first label is in contact with the surface and the undersurface of the second label is in contact with the top side of the first label.
