Release Paper Assembly for Folded Absorbent Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging for absorbent articles, such as sanitary napkins and incontinence pads, made from petroleum-derived materials like polypropylene and polyethylene films, contribute significantly to environmental pollution and are not eco-friendly.
Innovation Solution
Replace the conventional plastic wrappers with a release paper that maintains absorbent articles in a folded configuration, using a peeling agent like silicone to secure the articles without the need for additional packaging, allowing for a more sustainable packaging solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional plastic wrappers made from petroleum-derived materials are used to package absorbent articles, then the packaging provides protection and maintains the folded configuration, but the environmental impact increases and material usage increases
Solution Approach 1:
The patent changes the material parameter from petroleum-derived plastic to release paper, fundamentally altering the packaging material's origin and environmental properties while maintaining the protective function through the paper's barrier characteristics
Solution Approach 2:
The release paper serves as a disposable packaging element that is discarded after use, replacing the conventional plastic wrapper. This approach eliminates the need for complex recycling systems and reduces long-term environmental pollution while providing adequate protection during the product's shelf life
2Device complexity
If conventional plastic wrappers are used to maintain the folded configuration, then the packaging structure is simple and cost-effective, but the material usage increases and environmental friendliness decreases
Solution Approach 1:
The release paper performs multiple functions simultaneously: it maintains the folded configuration through its adhesive properties, provides protection against contaminants, and eliminates the need for separate plastic wrapping. This multi-functionality reduces overall material usage while keeping the packaging structure simple
Solution Approach 2:
The patent merges the functions of the protective wrapper and the folding-maintaining mechanism into a single release paper component. By combining these functions, the packaging structure becomes more efficient with reduced material usage compared to separate plastic wrapper and adhesive elements
3Object-generated harmful factors
If release paper is used instead of plastic wrappers, then the environmental impact is reduced and material usage is minimized, but the protection against moisture and contaminants must be maintained
Solution Approach 1:
The release paper is formulated as a composite material combining cellulose fibers with moisture-barrier properties and adhesive coatings. This composite structure provides both environmental benefits of natural materials and the necessary protective functions against moisture and contaminants
