Expandable Slit Sheet Labeling and Self-Sealing Wrap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing expandable slit sheet packaging materials face challenges in efficiently integrating labeling and securing wrapped items without the need for additional tapes or means, particularly when items are wider than the sheet width.
Innovation Solution
Incorporating unslit transverse regions in the expandable slit paper that can be adhered with labels or connected mechanically, and using an over-layer sheet with adhesive ends to bond with itself, allowing for secure wrapping and labeling without additional securing methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If labels are applied to expanded slit sheet material, then labeling is achieved, but the label cannot be applied flat and may cause unwinding
Solution Approach 1:
The label is applied to the slit sheet material before expansion, when the material is still in its compressed state. This preliminary action allows the label to be applied flat and secure, and the label remains in place after expansion because it is adhered to the material structure itself rather than being applied to the expanded surface.
2Ease of operation
If expandable slit sheet material is used for wrapping, then cushioning and flexibility are improved, but additional tapes or securing means are required
Solution Approach 1:
The securing function is merged with the wrap material itself by incorporating adhesive regions directly into the slit sheet structure. The adhesive regions are positioned to engage with adjacent layers or the surface being wrapped, eliminating the need for separate tapes or securing mechanisms while maintaining the cushioning and flexibility benefits of the expandable material.
Solution Approach 2:
The wrap material provides its own securing mechanism through integrated adhesive regions that activate upon expansion or during the wrapping process. The material serves both as the cushioning wrap and as its own securing system, eliminating the need for external tapes or fasteners.
3Manufacturing precision
If the sheet width is reduced to fit narrower items, then wrapping precision is improved, but the ability to wrap wider items is lost
Solution Approach 1:
The wrap material transitions from a compressed state with a smaller effective width to an expanded state with a larger effective width. This dynamic transformation allows the same material to adapt to different item widths - narrower items can be wrapped with the material in a less expanded state for precision, while wider items can accommodate the fully expanded material width.
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
Facilitates easy application of labels to unslit regions before expansion, ensuring the label remains flat and prevents unwinding, while the adhesive over-layer sheet securely wraps around items, eliminating the need for external securing methods and enhancing wrapping efficiency.
Implementation Method 1
an adhesive is applied to at least one end region of the over-layer sheet such that the over-layer sheet bonds to itself
