Multilayer Barrier Packaging for Abrasive Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Resin bonded abrasive articles, such as cut-off wheels, experience performance degradation due to exposure to environmental conditions during shipment and storage, particularly in humid environments, as conventional packaging materials like cardboard and shrink wrap allow air and moisture transfer, leading to fluctuations in environmental exposure.
Innovation Solution
A packaging system utilizing a flexible multilayer barrier composite with a water vapor transmission rate less than 0.5 grams per 645 square centimeters per 24 hours, which includes materials like aluminum, polyethylene, and nylon, to create a sealed environment that protects resin bonded abrasive articles from environmental fluctuations, maintaining a dry condition and preserving their performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional packaging materials like cardboard or shrink wrap are used, then packaging cost and ease of manufacture are improved, but moisture barrier performance deteriorates allowing environmental fluctuations to affect the abrasive article
Solution Approach 1:
The patent employs a multilayer composite packaging structure consisting of an inner moisture barrier layer (such as aluminum foil or vapor barrier plastic) and an outer protective layer (such as cardboard or shrink wrap). This composite structure combines the excellent moisture barrier properties of the inner layer with the mechanical strength and cost-effectiveness of the outer layer, effectively preventing moisture exposure while maintaining packaging simplicity
Solution Approach 2:
The patent utilizes flexible moisture barrier films and foils that can conform to the shape of abrasive articles while providing superior moisture protection. These thin film barriers are integrated into the packaging structure to create an effective moisture barrier without significantly increasing packaging complexity
2Duration of action of stationary object
If extended storage in humid conditions occurs, then storage duration is improved, but abrasive article performance deteriorates
Solution Approach 1:
The patent creates a moisture-controlled environment within the packaging by using moisture barrier materials that prevent humid external conditions from reaching the abrasive article. This effectively isolates the abrasive article in a stable, inert atmospheric environment that preserves performance during extended storage
Solution Approach 2:
The packaging structure is designed with pre-integrated moisture barrier layers that provide protection before any moisture exposure occurs. The barrier properties are built into the packaging structure itself, ensuring immediate protection upon packaging without requiring additional protective measures during storage
