Self-Adhesive Label Envelope for Hygienic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label production methods do not effectively seal stickers or cards from the exterior environment, leading to potential contamination issues, especially in hygienic environments like the food industry, and require manual handling and multiple production elements.
Innovation Solution
A self-adhesive label envelope is produced by using a double self-adhesive material with a liner and intermediate self-adhesive material, where the adhesive is destroyed and waste removed to create a sealed sticker or card that can be automatically applied using a labeling machine, minimizing manual work and ensuring hygiene standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stickers or cards are produced using conventional labeling methods, then production is simpler and faster, but the stickers or cards are not sealed from the exterior environment leading to potential contamination
Solution Approach 1:
The sticker or card is nested within a self-adhesive envelope structure that seals it from the exterior environment. The envelope comprises a body with a sealed interior space containing the sticker or card, creating a protected, contamination-free environment suitable for hygienic applications.
Solution Approach 2:
The sticker or card is pre-sealed within the envelope during the labeling process itself, rather than requiring separate sealing operations. The labeling machine applies the entire sealed envelope to the package in one operation, integrating the sealing function into the labeling step.
2Productivity
If manual handling is used for label production, then flexibility is maintained, but productivity decreases and hygiene standards are harder to maintain
Solution Approach 1:
The labeling machine automatically applies the sealed envelope to the package without manual intervention. The system is designed to be fed with rolls of self-adhesive material and can operate continuously, with the adhesive properties enabling automatic application rather than requiring manual placement.
Solution Approach 2:
The invention uses self-adhesive material with specific adhesive properties that enable automatic application by labeling machines. The adhesive strength and characteristics are optimized to allow automated handling and application while maintaining the sealed integrity of the envelope.
3Device complexity
If multiple production elements are used, then manufacturing flexibility is maintained, but the number of production steps increases
Solution Approach 1:
The invention combines multiple functions into a single integrated structure: the envelope body, the sealing mechanism, and the sticker or card containment are merged into one self-adhesive label unit. This eliminates the need for separate sealing operations and reduces the number of production elements required.
Solution Approach 2:
The self-adhesive envelope serves multiple functions simultaneously: it acts as the label carrier, provides sealing protection, enables automatic application, and maintains hygiene standards. This multi-functionality reduces the need for separate specialized components in the production system.

AI summary
The product Self-adhesive Label - Envelope (sealed in a roll) (3) is a self adhesive envelope in roll (1) that includes a sticker or a simple card (2) completely enclosed, that does not have any contact with the exterior environment of the self-adhesive envelope. The production of the product The product Self-adhesive Label - Envelope (sealed in a roll) (3) is produced with a single pass on a printing machine of self adhesive labels in a roll (4) which apart from the printing stations has the possibility of opening the self-adhesive material two times - one for printing and destroying the adhesive and one for inverted (5) and internal cutting, at least two cylindrical stations of die cutting [for right and inverted cutting (5) (the station for inverted cutting should also have a rewinding unit for the waste) and a station for cold lamination with a unit for the destruction of the adhesive.
