Packaging Document Holder with Reclosable Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document holders for shipment packages face issues with legibility, protection against damage, material intensity, and loss prevention, particularly due to the use of multiple overlapping transparent films and inadequate design for reuse.
Innovation Solution
A packaging solution using a single transparent polyethylene film with a reclosable joint and a peel-N-seal layer, allowing for multiple uses without damage, enhanced legibility, and minimal material consumption, which can be reused multiple times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple overlapping transparent films are used to enclose documents, then document protection against damage and loss is improved, but legibility for electronic readers deteriorates
Solution Approach 1:
The invention extracts the document enclosure function from the traditional multi-film pouch structure and integrates it directly into the packaging bag itself. The packaging bag is formed with a document enclosure area that has a document opening, eliminating the need for separate overlapping transparent films while maintaining protection and legibility.
Solution Approach 2:
The invention merges the document holder function with the packaging bag structure. The document enclosure area is formed as an integral part of the packaging bag, combining the protective function of the bag with the document holding function, thereby eliminating multiple separate film layers that hindered legibility.
2Reliability
If traditional document holders are designed with multiple films, then document security is improved, but material consumption increases
Solution Approach 1:
The invention combines the document holder and packaging bag into a single integrated structure. The document enclosure area is formed directly in the packaging bag material, eliminating the need for separate multi-film pouches and reducing overall material consumption while maintaining document security.
Solution Approach 2:
The packaging bag serves multiple functions: it protects the goods, encloses documents securely, and provides a structure that allows repeated opening and closing. This multi-functionality eliminates the need for separate document holder components, reducing material usage.
3Ease of manufacture
If document holders are designed for single use, then manufacturing simplicity is improved, but reusability deteriorates
Solution Approach 1:
The invention introduces a dynamic closing mechanism with a closing element that can be repeatedly opened and closed. The closing element engages with the document opening to secure documents during shipment but can be easily opened for access and reused for return shipments, transforming the structure from static single-use to dynamic multi-use.
Solution Approach 2:
The invention enables recovery and reuse of the packaging structure. The closing element can be disengaged and re-engaged multiple times, allowing the same packaging to be used for outbound and return shipments, thereby recovering the value of the packaging material instead of discarding it after single use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves legibility for electronic readers, ensures document protection, reduces material waste, and allows for multiple reuse cycles while maintaining document security during shipment.
Implementation Method 1
The transparent film is permanently joined, in particular by means of a thermal weld, to the packaging bag
