Multi-layer Tag with Cold Seal and Self-Adhesive Coatings

Solution Overview

Problem

Existing multi-layer tags lack versatility and additional self-adhesive labels, making them inconvenient for applications like airline baggage handling and requiring improved self-adhesive functionality and security features.

Innovation Solution

A multi-layer material comprising a self-adhesive layer on one web and a release layer on the other, with a cold-seal adhesive on the reverse side, allowing for easy application as a loop tag and incorporating RFID, security features, and printable layers for enhanced functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a multi-layer tag uses only cold-seal adhesive coating, then the tag can be easily applied and removed as a loop tag, but additional self-adhesive labels cannot be created

Engineering Contradiction:

Improveease of applicationVSAvoidversatility of label types

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The tag material is divided into multiple functional layers: a first web with self-adhesive coating for creating additional labels, and a second web with cold-seal adhesive coating for loop tag application. This segmentation allows the same material to serve multiple purposes - both as loop tags and as additional self-adhesive labels, resolving the contradiction between ease of operation and versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The multi-layer tag material is designed to perform multiple functions: it can be used as a loop tag with cold-seal adhesive, and simultaneously provides additional self-adhesive labels through the self-adhesive coating on the first web. This multi-functionality eliminates the need for separate materials for different label types, achieving both ease of operation and versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a multi-layer tag uses only self-adhesive coating, then additional self-adhesive labels can be created, but the tag cannot be easily removed after use
