Packaging Material Coating After Fiber Removal for Seamless Barriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging materials face inefficiencies in forming seamless barriers due to protruding fiber portions that allow liquids and grease to pass through, necessitating excessive coating material usage and increased costs.
Innovation Solution
A method and system involving localized heat treatment to remove fiber portions from a fibrous base material, followed by applying a coating layer to create a seamless barrier, using renewable and compostable polymers like PHA and PLA.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fiber portions are removed from the base material, then the barrier property is improved, but the manufacturing complexity increases
Solution Approach 1:
The fiber removal treatment is applied to the base material before coating, preparing the surface in advance to ensure proper coating adhesion and seamless barrier formation. This preliminary action eliminates the need for complex post-coating corrections
Solution Approach 2:
The patent replaces mechanical fiber removal methods with a chemical treatment process that dissolves or modifies fiber portions, simplifying the manufacturing system while achieving the same barrier improvement effect
2Reliability
If coating material is applied to cover fiber portions, then the barrier property is improved, but the quantity of substance increases
Solution Approach 1:
The patent extracts or removes the problematic fiber portions from the base material before coating, eliminating the need for excessive coating material to cover these defects. This results in reduced coating material usage while maintaining barrier integrity
Solution Approach 2:
By performing fiber removal as a preliminary step before coating, the patent creates an optimal surface that requires minimal coating material to achieve the desired barrier property, avoiding the need for excessive coating to mask fiber defects
3Reliability
If heat treatment is applied to remove fiber portions, then the barrier property is improved, but the use of energy increases
Solution Approach 1:
The patent optimizes the heat treatment parameters (temperature, time, intensity) to achieve effective fiber removal with minimal energy consumption, finding the optimal balance between processing effectiveness and energy usage
Solution Approach 2:
The patent replaces high-energy mechanical fiber removal methods with a chemical treatment process that requires significantly less energy while achieving the same barrier improvement effect
