Multilayer Film with Polyether Polymer for Washing Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current washing and cleaning technologies lack a washing and cleaning-active polymer film that contributes to the washing and cleaning process, as existing films primarily serve as packaging and do not enhance performance.
Innovation Solution
A multilayer film with at least one layer composed of a polymer composition obtained by radical polymerization of a monomer composition containing α,β-ethylenically unsaturated mono- and dicarboxylic acids, their salts, or anhydrides, in the presence of a (C8-C18) polyoxyalkylene ether, which contributes to dispersing, deposit-inhibiting, and surfactant properties during the washing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polyvinyl alcohol films are used for packaging detergents and cleaning agents, then the packaging function is fulfilled and dissolution occurs during washing, but the films do not contribute to washing and cleaning performance
Solution Approach 1:
The film is designed to perform multiple functions: it serves as packaging material while simultaneously providing washing and cleaning-active properties through the polymer composition containing polyether components that contribute to dispersing, deposit-inhibiting, and surfactant effects during the washing process
Solution Approach 2:
The packaging function and washing/cleaning function are merged into a single film structure. The film combines packaging capabilities with active cleaning ingredients embedded within the polymer matrix, allowing both functions to occur through one material rather than separate components
2Ease of operation
If polyvinyl alcohol film is used as packaging material, then convenient handling and protection from ingredient contact are achieved, but the film proportion (2-20% by weight) increases without providing cleaning performance
Solution Approach 1:
The film serves itself by incorporating washing and cleaning-active properties directly into its polymer composition. Instead of being a passive packaging material that merely protects and dissolves, the film actively contributes to the cleaning process, reducing the need for additional separate packaging materials or inactive fillers
3Adaptability or versatility
If separate multi-chamber systems are used to contain different active ingredients, then incompatible ingredients can be separated and new formulation concepts are enabled, but the complexity of the packaging structure increases
Solution Approach 1:
The film can be designed with segmented or multi-chamber structures to separate incompatible ingredients, while still maintaining the overall simplicity of a single-film packaging solution. The segmentation is achieved within the polymer matrix rather than requiring complex external packaging structures
Solution Approach 2:
Multiple functional chambers or compartments for different active ingredients are nested within the single film structure, allowing complex formulations to be contained in what appears to be a simple film packaging
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
The multilayer film effectively enhances washing and cleaning performance by releasing active ingredients in a controlled manner, stabilizing embedded ingredients, and providing stable formulations suitable for various detergent and cleaning agent forms.
