Universal Label With Selective Adhesive Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current labeling solutions for steam-sterilizable products require separate labels and printers for soft and hard packaging, lacking a universal label that can adhere securely to both without leaving residue and be used for documentation after sterilization.
Innovation Solution
A universal label with multiple adhesive faces of different adhesive properties, covered by a removable film, allowing selective exposure for secure adhesion to both soft and hard packaging, and easy removal without residue, enabling single-label use for both packaging types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single label is used for both soft and hard packaging, then device complexity is reduced, but adhesive performance for different packaging types cannot be satisfied simultaneously
Solution Approach 1:
The label is divided into multiple adhesive zones with different adhesive properties. The first adhesive zone is designed for soft packaging with higher tack and permanent bonding, while the second adhesive zone is designed for hard packaging with lower tack and removable bonding. This segmentation allows a single label to adapt to different packaging types without requiring separate label systems.
Solution Approach 2:
Different regions of the label backside are assigned different adhesive characteristics tailored to specific packaging surfaces. The label incorporates a gradient or zoned adhesive structure where adhesive strength and permanence vary by location, enabling optimal performance on both soft and hard packaging surfaces within a single label design.
2Strength
If permanent adhesive is used for soft packaging, then bonding strength is improved, but residue remains after removal from hard packaging
Solution Approach 1:
The adhesive backside is segmented into distinct zones: a permanent adhesive region for soft packaging application and a removable adhesive region for hard packaging application. This prevents the use of permanent adhesive on hard packaging where residue would be problematic, while still providing strong bonding for soft packaging.
Solution Approach 2:
The label incorporates locally differentiated adhesive properties where the adhesive composition, thickness, or curing characteristics vary by zone. This allows the label to provide permanent, residue-free bonding on soft packaging while providing temporary, easily removable bonding on hard packaging without leaving residue.
3Reliability
If separate labels are used for soft and hard packaging, then adhesive performance is optimized for each type, but device complexity and operational efficiency decrease
Solution Approach 1:
Two previously separate labeling systems (one for soft packaging, one for hard packaging) are merged into a single universal label design. The label integrates multiple adhesive zones, printing capabilities, and removal characteristics into one unified structure, allowing operators to use the same label and application process for both packaging types.
Solution Approach 2:
The label is designed as a multi-functional universal label that can be applied to both soft and hard packaging surfaces. It incorporates multiple adhesive zones with different properties, enabling a single label type to replace multiple specialized label types, thereby simplifying inventory, application procedures, and improving operational efficiency.
4Ease of operation
If a label is designed for hard packaging with removable adhesive, then ease of removal is improved, but bonding strength to soft packaging is insufficient
Solution Approach 1:
The adhesive system is segmented into zones with different bonding strengths. The removable adhesive zone provides easy removal for hard packaging applications, while the permanent adhesive zone provides strong bonding for soft packaging applications. This segmentation resolves the contradiction by providing the appropriate adhesive strength for each packaging type within the same label.
Solution Approach 2:
The label incorporates locally optimized adhesive properties where adhesive strength, tack, and permanence are tailored to the specific packaging type. Soft packaging areas receive high-strength permanent adhesive characteristics, while hard packaging areas receive low-strength removable adhesive characteristics, achieving both strong bonding and easy removal where needed.

Function Achieved in This Case
Enables secure, residue-free labeling and documentation for both soft and hard packaging using a single label material and printer, simplifying the process and eliminating the need for separate labels and devices.
Implementation Method 1
The universal label has different adhesives with different adhesive properties which are covered in such a way that they can be exposed selectively individually and separately from each other for their respective adhesive actions
