Multilayer Film with Surfactant Properties for Detergent Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current polymer films used for packaging detergents and cleaning agents do not contribute actively to the washing or cleaning process and lack multifunctional properties such as dispersing, deposit-inhibiting, and surfactant properties, which are essential for enhanced cleaning performance.
Innovation Solution
A multilayer film is developed with at least one layer composed of a polymer composition obtained by radical polymerization of α,β-ethylenically unsaturated mono- and dicarboxylic acids, their salts, and anhydrides in the presence of a polyether component, providing dispersing, emulsifying, and surfactant properties that actively participate in the washing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If polyvinyl alcohol films are used for packaging detergents, then the films dissolve and release ingredients, but the films do not contribute actively to washing or cleaning performance
Solution Approach 1:
The patent applies multi-functionality by developing polymer films that simultaneously serve as packaging material and active cleaning agent. The film contains polymer chains with carboxylic acid groups that provide both packaging function (encapsulation, controlled release) and cleaning function (surfactant properties, dispersing, deposit-inhibiting), eliminating the need for separate functional components.
Solution Approach 2:
The patent merges the packaging function and cleaning function into a single integrated material system. The polymer film combines structural integrity for packaging with active cleaning properties, merging what were previously separate functions (packaging material + cleaning agent) into one multifunctional component.
2Ease of operation
If polymer films are used for detergent packaging, then ingredients are released, but the films lack active contribution to washing and cleaning
Solution Approach 1:
The polymer film is designed to perform multiple functions: it acts as the packaging barrier, controls ingredient release through its solubility and degradation, and simultaneously provides active cleaning performance through its surfactant and dispersing properties, eliminating the need for separate functional additives.
Solution Approach 2:
The film is self-functional, meaning it provides both packaging and cleaning functions without requiring external additives or separate components. The polymer itself possesses the necessary active ingredients and properties to contribute to washing performance while maintaining its packaging function.
3Device complexity
If conventional polymer films are used, then packaging is provided, but multifunctional properties like dispersing and surfactant properties are lacking
Solution Approach 1:
The patent employs composite material strategies by incorporating multiple functional groups and properties into a single polymer film system. The film combines structural polymer matrix with functional groups (carboxylic acid, surfactant moieties) to achieve both packaging integrity and multifunctional cleaning capabilities in one material.
Solution Approach 2:
The polymer film is designed to perform multiple functions: it acts as the packaging barrier, controls ingredient release through its solubility and degradation, and simultaneously provides active cleaning performance through its surfactant and dispersing properties, eliminating the need for separate functional additives.
