Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pallet wrapping materials, such as plastics, are non-recyclable and unsuitable for use with paper due to structural deficiencies, limiting the effectiveness of paper materials in providing adequate protection and support for pallets.
Innovation Solution
Development of an expandable slit sheet paper with a specific slit pattern that forms open cells upon expansion, combined with a support wrap, to create a recyclable and highly effective pallet wrap that offers increased tensile strength and flexibility for wrapping pallets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional plastic wrapping materials are used, then adequate protection and support for pallets is provided, but the materials are non-recyclable and incompatible with paper products
Solution Approach 1:
The patent transforms conventional plastic wrap into a recyclable paper-based alternative by changing the material parameter from plastic to expandable paper with specific slit patterns, maintaining protective functionality while enabling recyclability
Solution Approach 2:
The invention creates a composite structure combining expandable paper material with specific slit patterns and optional support wraps to achieve both the protective properties of plastic and the recyclability of paper
2Object-affected harmful factors
If traditional paper materials are used for pallet wrapping, then recyclability is achieved, but structural deficiencies prevent adequate protection and support
Solution Approach 1:
The paper is segmented into a slit pattern creating expandable cells that provide structural support and protection, transforming flat paper into a three-dimensional protective structure
Solution Approach 2:
The expandable paper transitions from a two-dimensional flat sheet to a three-dimensional structured wrap through expansion of the slit pattern, gaining volumetric protection capability
3Reliability
If expandable slit sheet paper with slit patterns is used, then recyclability and expanded protection are achieved, but the complexity of the slit pattern manufacturing increases
Solution Approach 1:
The manufacturing process segments the paper into predetermined slit patterns that enable expansion, creating the protective structure through controlled division rather than complex assembly
Solution Approach 2:
The slit patterns are pre-formed during paper manufacturing, preparing the material for expansion and protection functions before the actual wrapping application occurs
