Embedded Chips in Security Paper Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security papers with electronic chips for fraud detection are complex and costly to manufacture, and the chips are not adequately anchored to the paper, making them prone to damage.
Innovation Solution
Embedding electronic chips directly into the paper sheet during its formation from wet cellulose fibre pulp and optionally incorporating them between two sheets, ensuring firm anchoring and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chips are applied onto a support and glued or fixed onto the previously formed paper sheet, then the security paper can be manufactured with existing technology, but the application process becomes relatively complicated and costly, and the chips cannot be appropriately anchored to the paper sheet
Solution Approach 1:
The chips are introduced into the paper sheet during the paper formation process, before the paper is completely dried and set. This preliminary action allows the chips to be embedded in the wet pulp, ensuring proper anchoring without requiring separate application and gluing steps that would increase process complexity
Solution Approach 2:
The chip introduction step is merged with the paper formation process. Instead of applying chips to a finished paper sheet as a separate operation, the chips are introduced during the same continuous process that forms the paper, combining two operations into one and reducing overall process complexity
2Reliability
If chips are applied onto a previously formed paper sheet, then the paper can be manufactured first and chips added later, but the chips remain exposed on the surface and are subject to possible damage unless coated with a protective layer
Solution Approach 1:
The chips are nested within the paper sheet structure itself by embedding them in the wet pulp during formation. The paper material surrounds and encases the chips, providing inherent protection without requiring additional protective coating layers that would increase process complexity
Solution Approach 2:
The chips are embedded in the wet pulp before the paper dries and sets, ensuring they become enclosed within the paper matrix. This preliminary embedding action provides protection before the paper structure is finalized, eliminating the need for subsequent protective coating steps
3Reliability
If chips are applied onto a support and glued onto the paper sheet, then the chips can be attached to the paper, but the application process becomes relatively costly
Solution Approach 1:
The chip attachment is merged with the paper formation process itself. The chips are introduced during the same continuous operation that forms the paper, eliminating the need for separate gluing or adhesive application steps that would increase manufacturing cost
Solution Approach 2:
The wet pulp itself serves as the embedding medium, requiring no additional adhesives or bonding agents. The natural properties of the wet paper material provide the anchoring function, eliminating the need for separate attachment materials and reducing manufacturing cost

AI summary
A manufacturing method of a security paper material, in particular for labelling and packaging, comprising the steps of forming a paper sheet from a wet cellulose fiber pulp and providing the paper sheet with electronic chips; the chips are introduced into the paper sheet being formed during the transformation step of the pulp into paper and are deposited directly onto the wet pulp and at least partially embedded in the pulp. Optionally, an auxiliary paper sheet is coupled to the paper sheet provided with the chips so that the chips are incorporated between the two sheets.
