Packaging Machine Using PE Film for Sleeve Group Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outer packaging made of board or corrugated board is prone to dust, moisture absorption, and structural issues such as buckling, leading to increased waste and transportation costs, while failing to maintain sterility and stability during the transportation and storage of packaging sleeves.
Innovation Solution
A packaging machine that uses a sheet material, such as a PE film, to encase packaging sleeves perpendicularly, with a conveyor unit and sealing unit to form a compact and sealed outer packaging unit, reducing material costs and waste, and ensuring sterility and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional board or corrugated board is used for outer packaging, then structural strength and protection are provided, but dust generation, moisture absorption, and waste increase occur
Solution Approach 1:
The patent replaces conventional rigid board packaging with flexible sheet material (such as PE film) that wraps around the packaging sleeve group. This flexible film packaging eliminates dust generation and moisture absorption issues inherent in board materials while providing adequate protection through proper sealing and wrapping.
2Strength
If board outer packaging is used, then protection during transport is achieved, but weight and volume increase leading to higher transportation costs
Solution Approach 1:
The flexible sheet material (PE film) used in the invention is significantly lighter than conventional board or corrugated board packaging. The film wraps tightly around the packaging sleeve group, providing protection during transport while minimizing weight and volume, thereby reducing transportation costs.
3Strength
If board outer packaging is used, then packaging sleeves are protected, but sterility cannot be maintained due to dust and contamination
Solution Approach 1:
The flexible PE film packaging creates a sealed barrier around the packaging sleeve group, preventing dust and contaminants from reaching the contents. The film can be sealed at the ends to maintain sterility throughout transport and storage, unlike open board packaging that generates dust and allows contamination.
4Reliability
If conventional sealing methods are used, then packaging is secured, but material costs and waste increase
Solution Approach 1:
The flexible sheet material is sealed at the ends using conventional sealing methods (such as heat sealing), providing secure packaging while using minimal material. The film wraps tightly around the packaging sleeve group, eliminating the need for excessive packaging materials and reducing waste compared to conventional board packaging.
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 provides a cost-effective, lightweight, and compact packaging unit that minimizes dust and moisture exposure, reduces waste, and maintains the sterility of packaging sleeves during transportation and storage, while enhancing stability and space efficiency.
Implementation Method 1
a heat treatment unit behind the outer packaging unit to apply the protruding sheet material to the front sides of the packaging sleeve group
Implementation Method 2
a sealing unit is provided for sealing of the sheet material enclosed in the packaging sleeve group

AI summary
Shown and described are a packaging machine and a method for producing a packaging unit from a packaging sleeve group comprising a plurality of flat folded, upright packaging sleeves, and an outer packaging. It is provided that the packaging machine comprises at least one conveyer unit for conveying the packaging sleeve group in a conveyor direction perpendicular to the longitudinal extent of the packaging group and at least one outer packaging unit for preparing an outer packaging-shaping sheet material in a base position, and in that, seen in the conveyor direction behind the sheet material in the base position, a sealing unit is provided for sealing of the sheet material enclosed in the packaging sleeve group.
