Paper-board Packaging with Vertical Flaps for Plastic Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for liquids and food products heavily relies on thermoshrinking plastic materials and stretch materials, which are environmentally polluting, non-biodegradable, and inefficient in reducing plastic usage.
Innovation Solution
A packaging system that utilizes a sheet-like support made from a stiffened paper-board blank, folded to form a support base and vertical flaps, without plastic wrapping, and incorporates a handleable band for secure transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermoshrinking plastic material or stretch material is used for wrapping containers, then the packaging provides structural protection and ease of handling, but it causes environmental pollution and is non-biodegradable
Solution Approach 1:
The patent removes the plastic wrapping layer entirely from the packaging system. Instead of using thermoshrinking or stretch materials to wrap containers, the invention uses a sheet-like support structure with vertical flaps that provide protection without requiring plastic envelopes, thereby eliminating the harmful environmental factors associated with plastic pollution while maintaining structural functionality
Solution Approach 2:
The patent changes the material parameter from plastic/thermoshrinking materials to paper-board material. This material substitution maintains the protective function while improving biodegradability and reducing environmental harm, as paper-board is naturally biodegradable and can be composted unlike synthetic plastic materials
2Strength
If plastic materials are used for packaging, then the packaging provides durability and protection, but the recovery process is polluting and reduces biodegradability
Solution Approach 1:
The patent employs a disposable paper-board packaging structure that is designed to be discarded after use rather than recovered. The sheet-like support with vertical flaps provides sufficient protection during use and can be easily disposed of in a biodegradable manner, eliminating the need for complex recovery processes that would otherwise be required for plastic materials
3Object-affected harmful factors
If a sheet-like support made from paper-board blank is used instead of plastic material, then biodegradability and environmental friendliness are improved, but the structural strength and protection may be compromised
Solution Approach 1:
The patent divides the support structure into multiple functional segments: a sheet-like support base and separate vertical flaps. This segmentation allows each component to be optimized for its specific function - the base provides structural support while the flaps provide protective wrapping - achieving both biodegradability and sufficient structural strength through functional division
Solution Approach 2:
The patent uses composite construction by combining paper-board material with adhesive elements and structural folding. The sheet-like support is formed by folding the paper-board blank into specific geometries with vertical flaps that extend upward, creating a composite structure that leverages the strength of the folded paper-board configuration to provide adequate protection while maintaining biodegradability
4Ease of manufacture
If traditional plastic packaging is used, then ease of manufacture and production efficiency are maintained, but environmental sustainability is compromised
Solution Approach 1:
The patent incorporates printing of information directly onto the sheet-like support structure during the manufacturing process. This preliminary action of printing on the paper-board blank eliminates the need for separate labeling steps and maintains production efficiency, while the entire paper-board package remains environmentally sustainable and biodegradable
