Paper-Laminate Detergent Bag for Moisture and Leakage Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Detergent manufacturers face challenges in developing environmentally friendly packaging that provides good leakage protection, moisture protection, and freshness while using high amounts of paper, which traditional packaging materials fail to address.
Innovation Solution
A laminate structure is formed using a thin polyethylene or polypropylene inner layer bonded with an outer paper layer, combined with a recloseable zipper, to create a flexible bag for water-soluble detergent articles, ensuring improved environmental profile and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a very high percentage of paper is used in detergent packaging, then environmental sustainability is improved, but leakage protection and moisture protection deteriorate
Solution Approach 1:
The patent applies composite materials by creating a laminate structure that combines paper (for sustainability) with polyethylene or polypropylene (for barrier properties). The paper layer constitutes above 85 wt% to 94 wt% of the flexible bag, while the polyalkylene layer makes up 3.0 wt% to less than 10.0 wt%, with the polyalkylene layer having a thickness of 6 μm to 10 μm. This composite structure resolves the contradiction by integrating the environmental benefits of paper with the protective qualities of plastic.
2Reliability
If a very high percentage of paper is used in detergent packaging, then environmental sustainability is improved, but freshness profile deteriorates
Solution Approach 1:
The laminate structure combining paper with polyethylene or polypropylene provides both environmental sustainability and freshness protection. The paper layer delivers the environmental profile while the polyalkylene layer maintains freshness by preventing moisture and air penetration, thus resolving the contradiction between sustainability and freshness preservation.
3Reliability
If existing packaging ingredients are replaced with high amounts of paper, then environmental profile is improved, but leakage protection deteriorates
Solution Approach 1:
The patent resolves this contradiction by using a composite laminate where paper (above 85 wt% to 94 wt%) provides the improved environmental profile while a polyalkylene layer (3.0 wt% to less than 10.0 wt%, with thickness of 6 μm to 10 μm) ensures adequate leakage protection. The combination allows both goals to be achieved simultaneously.
4Reliability
If existing packaging ingredients are replaced with high amounts of paper, then environmental profile is improved, but moisture protection deteriorates
Solution Approach 1:
The laminate structure combines paper (providing environmental profile) with polyethylene or polypropylene (providing moisture barrier). The paper layer constitutes above 85 wt% to 94 wt% while the polyalkylene layer (3.0 wt% to less than 10.0 wt%, thickness of 6 μm to 10 μm) ensures moisture protection, thus resolving the contradiction between environmental profile and moisture protection.

AI summary
A detergent product includes a flexible bag and water-soluble detergent articles. The water-soluble detergent articles are contained inside the flexible bag. The flexible bag includes from above about 85 wt % to about 94 wt % of a paper layer; from about 3.0 wt % to less than about 10.0 wt % of a polyalkylene layer selected from polyethylene and/or polypropylene layer having a thickness of from about 6 μm to about 10 μm; and from about 3.0 wt % to about 6.0 wt % recloseable zipper. The paper and polyalkylene layer are bonded together in a laminate structure with the paper layer being the outer layer and the polyalkylene layer being the inner layer.
