Single-Ply Piggyback Label With Silicone Release Patch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing piggyback labels require three substrates due to structural weaknesses caused by die cuts, leading to printer jams and inefficiencies in auto applicator systems.
Innovation Solution
A single ply piggyback label design that uses a liner substrate, a label substrate, and a removable label substrate, where the removable label is aligned over a silicone release patch on the primary label, allowing for seamless separation and application without requiring a second liner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If three substrates (two liners and a label substrate) are used to provide structural support, then the structural strength is improved, but the device complexity increases
Solution Approach 1:
The patent combines the functions of multiple substrates into a single liner substrate. The single liner provides both the structural support previously requiring three substrates and the release surface for label application, eliminating the need for separate waste liner and second liner while maintaining all necessary functions
Solution Approach 2:
The single liner substrate serves multiple functions simultaneously: it provides structural support, acts as the release surface for label application, and functions as the waste material to be rewound. This multi-functional design eliminates the need for multiple specialized substrates
2Ease of operation
If die cuts are made in the liner for the removable label, then the label separation is improved, but the liner strength deteriorates causing jams in the rewinder
Solution Approach 1:
The patent segments the label structure from the liner by using a silicone release patch that allows the removable label to be separated from the primary label without creating holes in the liner. The liner remains intact while still enabling label separation through the release properties of the silicone patch
Solution Approach 2:
The silicone release patch acts as an intermediary between the removable label and the primary label, enabling separation without direct mechanical connection to the liner. This mediator allows label separation while preserving liner integrity
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 solution prevents printer jams by maintaining the integrity of the waste liner during rewinding, ensuring smooth operation of auto applicator systems and allowing for easy separation and application of the removable label.
