Biodegradable Multi-Pack Carrier Using Prodegradant Polyolefins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible plastic container carriers are not biodegradable, leading to environmental issues due to long decomposition times and accumulation in landfills, despite offering strength, flexibility, and water resistance.
Innovation Solution
Development of biodegradable flexible container carriers using biodegradable plastic materials such as polyolefins mixed with prodegradant additives, co-resins, or structural polymers, which facilitate decomposition through oxidative degradation or hydrolysis, allowing for flexibility and strength while being environmentally friendly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional plastic materials are used for container carriers, then strength and water resistance are maintained, but biodegradability is lost and environmental harm increases
Solution Approach 1:
The patent applies composite materials by combining biodegradable polymers (such as polylactic acid, polyhydroxyalkanoates, or starch-based polymers) with traditional plastic materials. This composite structure allows the carrier to maintain the strength and water resistance of conventional plastics while incorporating biodegradable components that enable environmental degradation after use, thus resolving the contradiction between durability and environmental harm.
2Object-affected harmful factors
If biodegradable materials are used to replace plastic, then environmental friendliness improves, but strength and water resistance deteriorate
Solution Approach 1:
The patent applies local quality by creating a multi-layer structure where different regions of the carrier have different material properties. The outer layers or specific functional zones use water-resistant biodegradable polymers that protect against moisture during use, while inner layers or specific sections use highly biodegradable materials that facilitate rapid decomposition after use. This spatial differentiation of material properties allows the carrier to be both environmentally friendly and reliable during its service life.
