Foldunder Label for Sealed Cartons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labeling methods are inefficient for applying shipping, packing list, and return shipping labels to sealed cartons, as they require opening the carton to insert labels, which is not practical for high-volume shipping and concealing packing list information until delivery.
Innovation Solution
The development of foldunder labels, comprising a first label sheet with a central region and frame, a second label sheet with a central portion and frame, and a carrier material with sections separated by a line of demarcation, allowing for printing and application of labels without opening the carton, with the first label sheet's central region being removable to expose adhesive for secure attachment to the carrier material, enabling easy application and concealment of packing list information.

Engineering Contradiction Analysis
1Productivity
If existing labeling methods are used to apply shipping, packing list, and return shipping labels, then labels can be attached to packages, but the carton must be opened to insert labels which reduces efficiency and exposes packing list information
Solution Approach 1:
The label system is divided into multiple segments: a first label sheet for the shipping label, a second label sheet for the packing list, and a third label sheet for the return shipping label. These segments are arranged in a specific configuration where the second label sheet is positioned between the first and third label sheets, allowing all labels to be applied simultaneously to the exterior of the sealed carton without opening it.
Solution Approach 2:
The label sheets are nested within each other in a layered configuration. The second label sheet (packing list) is nested between the first label sheet (shipping label) and the third label sheet (return shipping label). This nesting arrangement allows the packing list to be concealed between the outer labels while still being attached to the package, maintaining security and efficiency.
2Ease of operation
If the carton is opened to insert labels, then labels can be applied to the package, but the process becomes time-consuming and impractical for high-volume shipping
Solution Approach 1:
All label sheets are pre-configured and pre-positioned on the package exterior before the packing process is complete. The first, second, and third label sheets are arranged in their final positions on the sealed carton, eliminating the need to open the carton later to insert labels. This preliminary arrangement of all labeling components resolves the contradiction by making label application accessible while avoiding the time loss of opening and closing cartons.
3Productivity
If multiple labels are applied separately to sealed cartons, then each label can be attached independently, but the process becomes complex and time-consuming
Solution Approach 1:
Multiple label sheets (first, second, and third label sheets) are merged into a single integrated labeling system that can be applied simultaneously to the sealed carton. The labels are positioned in specific regions (first, second, and third regions) and can be attached in one operation rather than separately, achieving rapid label attachment while managing complexity through unified design.

AI summary
A foldunder label includes a first label sheet with a top side and an opposing underside and a first label line of weakness defining a central region of the first label sheet; and a second label sheet comprising an upper side and an opposing lower side and a second label line of weakness defining a central portion of the second label sheet; and a carrier material with a first section and a second section separated by a line of demarcation, a first section line of weakness underlying the first label, and a second section line of weakness underlying the second label, wherein the underside of the first label sheet is removably adhered to the first section and the lower side of the second label sheet is removably adhered to the second section.
