Recyclable Paper Packaging with 3D Network Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging structures in logistics and express deliveries face challenges with non-recyclable buffer materials, leading to environmental pollution and poor working conditions due to the use of plastic films and powdery buffer materials.
Innovation Solution
A fully recyclable environmental protection packaging structure featuring a paper-based planar structure with a three-dimensional network protecting layer, formed by die-cutting and stretching paper, which serves as a buffer and can be easily recycled without separation issues, reducing environmental harm and health risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic film is used to cover the inner wall of paper packaging structure for adhering buffer materials, then the buffer structure can be adhered to the packaging, but the plastic film cannot be separated during recycling causing environmental pollution
Solution Approach 1:
The patent removes the plastic film component entirely from the packaging structure, extracting the harmful element while maintaining the functional requirement of buffer adhesion through direct attachment to the paper inner wall without any plastic intermediary layer
Solution Approach 2:
The patent changes the material parameter from plastic film to paper-based buffer material that can be directly adhered to the paper packaging inner wall, transforming the system to use only recyclable materials while maintaining adhesion functionality
2Strength
If powdery and granular buffer materials are used to fill packaging structures, then effective buffer protection is provided, but the production environment becomes harmful to worker health
Solution Approach 1:
The patent uses a three-dimensional network structure with porous characteristics that provides buffer protection through its structural configuration rather than through loose powdery materials, eliminating the health hazard while maintaining the protective function
Solution Approach 2:
The patent creates a composite paper-based buffer structure combining the inner wall paper with a three-dimensional network layer, forming an integrated recyclable packaging system that eliminates harmful powdery materials while providing effective buffer protection
3Strength
If plastic foam and plastic board are used as buffer materials, then effective shock absorption is achieved, but the materials cannot be directly adhered to paper packaging requiring plastic film coverage
Solution Approach 1:
The patent merges the buffer material with the paper packaging structure by directly adhering paper-based buffer material to the inner wall, combining multiple functions into a single integrated structure and eliminating the need for separate plastic film layers
Solution Approach 2:
The patent changes the buffer material parameter from plastic-based (foam and board) to paper-based three-dimensional network structure, allowing direct adhesion to paper packaging while maintaining shock absorption capability and enabling recyclability

AI summary
A fully recyclable environmental protection packaging structure applied to express deliveries, postal services and logistics and made of a planar structure of paper. The packaging structure includes a first surface and a protecting layer overlapped on the surface. The protecting layer includes at least one layer of liner which is a three-dimensional network structure. The packaging structure of the present disclosure can overcome problems that kraft paper bubble bags or envelopes, and paper and plastics can't be separated and recycled to pollute environment in the prior art. At the same time, it can solve technical problems of dust pollution and poor air quality caused by using powdery and granular soft structures used as buffers.
