Label Medium Peeling Direction Indication for Frame Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing label medium design often results in inefficient peeling of the frame part, leading to the label part being peeled off together, due to incomplete cutting of the adhesive layer and small adhesion area at the corner portions, which complicates the peeling process and can result in wasted labels.
Innovation Solution
A label medium with a peeling direction indicating portion, such as a printed arrow or tab, on the frame part to guide the peeling direction perpendicular to one side of the label part, ensuring the frame part is peeled off without the label part, and a label manufacturing apparatus that incorporates a cutting mechanism to create this indication during printing and cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adhesive sheet is half-cut along the outline of each label part, then the label part can be separated from the release sheet, but the frame part may be peeled off together with the label part due to incomplete cutting or small adhesion area at corner portions
Solution Approach 1:
The frame part is divided into multiple peeling sections by cutting lines that extend from the label part outlines to the frame part edges. This segmentation creates independent peeling zones, allowing the frame part to be separated in controlled sections rather than as a single unit, preventing accidental label part detachment
Solution Approach 2:
A peeling instruction mark is introduced as an intermediary element between the frame part and the label part. This mark serves as a visual guide and physical starting point for peeling operations, directing users to begin peeling at specific locations where the adhesive bond is weakest or most controlled, thereby preventing label part detachment
2Ease of operation
If the user peels off the frame part from an oblique direction, then the peeling process starts easily, but the label part may be coupled to the frame part and peeled off together
Solution Approach 1:
The peeling instruction mark is pre-positioned at optimal locations on the frame part before peeling occurs. These marks indicate predetermined starting points and directions for peeling, guiding users to initiate the peeling process in a controlled manner that prevents label part detachment while maintaining ease of operation
3Reliability
If the adhesive layer is not completely cut during half-cutting, then the label part remains adhered to the release sheet, but the frame part and label part may adhere together causing peeling difficulties
Solution Approach 1:
The frame part is segmented into multiple peeling sections by cutting lines that create independent zones. This segmentation allows each section to be peeled separately with controlled adhesive separation, reducing the complexity of peeling the entire frame part at once while maintaining reliable label part adhesion to the release sheet

AI summary
A label medium and an apparatus for manufacturing the label medium are provided. The label medium includes a release sheet and an adhesive sheet temporarily adhered to the release sheet. The adhesive sheet has a base layer and an adhesive layer provided on the base layer. The adhesive sheet includes a plurality of label parts printed on the base layer and a frame part provided outside the label parts. The adhesive sheet is cut along an outline of each of the label parts. The frame part includes a peeling direction indicating portion to indicate a peeling direction in which the frame part is peeled off from the release sheet, the peeling direction being substantially perpendicular to one side of the outline of the label part.
