Packaging Machine Handle Integration via Film Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines require additional steps and resources to incorporate handles into packaged containers, which can reduce productivity and complicate the packaging process.
Innovation Solution
A method and machine design that integrates a narrower additional film as a handle onto the lidding film during the sealing process, sealing it to the perimetral edge of the container without requiring extra operations or stations, allowing the handle to be formed simultaneously with the sealing of the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handle is incorporated into packaged containers using existing packaging machines, then the handling capability of containers is improved, but the packaging time increases and productivity decreases
Solution Approach 1:
The patent combines the handle formation operation with the existing sealing operation by integrating an additional film feeding system into the sealing station. The additional film is fed and sealed simultaneously with the lidding film, merging two functions (sealing and handle formation) into a single operational cycle, thereby improving handling capability without increasing packaging time
Solution Approach 2:
The sealing station is designed to perform multiple functions: sealing the lidding film to the container and simultaneously forming the handle by sealing the additional film. This multi-functional approach allows the same machinery to accomplish both tasks, eliminating the need for separate handle formation equipment and maintaining productivity while improving ease of operation
2Ease of operation
If a handle is incorporated into packaged containers using existing packaging machines, then the handling capability of containers is improved, but the device complexity increases due to additional stations or machinery
Solution Approach 1:
The patent merges the handle formation function into the existing sealing station by integrating an additional film feeding mechanism. This consolidation avoids the need for separate handle formation stations or additional machinery, thereby improving handling capability while minimizing increases in device complexity
Solution Approach 2:
The sealing station is designed to perform multiple functions: sealing the lidding film and simultaneously forming the handle. This multi-functional design eliminates the need for dedicated handle formation equipment, reducing overall machinery complexity while improving ease of operation
3Ease of operation
If additional film is added to form a handle during the sealing process, then the handling capability is improved, but the amount of material used increases
Solution Approach 1:
The patent applies local quality by using a narrower additional film specifically for handle formation only where needed on the container, rather than covering the entire container. This localized approach provides the necessary handling capability while minimizing the quantity of additional material used compared to full-container coverage

AI summary
Method for a packaging machine and a packaging machine comprising a sealing station (101) where at least one container with a perimetral edge is arranged and a lidding film is arranged on the container, such that the lidding film covers the container in said sealing station (101). The lidding film is sealed to the perimetral edge of the container. Furthermore, an additional film narrower than the container is added on the lidding film as a handle in the sealing station, the additional film being arranged longitudinally on the lidding film in the positioning step, and said additional film is sealed to the lidding film on the perimetral edge of the container.
