Stretch Film Roll Bundle Packaging With Integrated Lifting Tie
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packages for stretch film rolls are bulky, inconvenient to handle, and inefficient in terms of packaging material usage, with a risk of damage during transport due to roll movement.
Innovation Solution
A package design that holds stretch film rolls firmly together using a combined tying and lifting member, minimizing movement and reducing packaging material, allowing horizontal lifting and incorporating traceability features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional packaging materials (cardboard boxes, shrink film, stretch film) are used to package stretch film rolls, then the rolls are protected during transport, but excessive packaging material is required and the packages are inconvenient to lift and carry
Solution Approach 1:
The patent combines the tying function and lifting function into a single integrated member. The lifting member is wrapped around the bundle of stretch film rolls and its ends are joined together, creating one component that simultaneously secures the rolls and provides lifting capability. This eliminates the need for separate tying materials and lifting mechanisms, reducing packaging material while improving handling convenience.
Solution Approach 2:
The lifting member serves multiple functions: it acts as a tying element to secure the rolls together, provides a handle for lifting and carrying, and maintains the horizontal orientation of rolls during transport. This multi-functional design addresses both protection and handling requirements without needing additional components.
2Stability of the object's composition
If stretch film rolls are packaged vertically, then they are stable during transport, but there is less space between the ground and the package when lifted
Solution Approach 1:
Instead of packaging rolls vertically with the lifting point at the top, the patent inverts the arrangement by packaging rolls horizontally with the lifting member wrapping around the bundle. This inversion allows the lifting force to be applied at the center of gravity, maintaining stability while maximizing clearance space between the package and the ground during lifting operations.
3Ease of operation
If loose rolls are packed on pallets, then they are easy to store, but they move during transport increasing the risk of damage
Solution Approach 1:
The lifting member simultaneously provides tying functionality to secure rolls together and lifting functionality for handling. By wrapping the member around the bundle and joining its ends, the rolls are firmly held together while maintaining ease of lifting and storage, eliminating the movement and damage risks associated with loose roll packing.
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 package securely holds rolls together, reduces packaging waste, enhances handling convenience, and facilitates inventory management with integrated traceability.
Implementation Method 1
The package comprises at least one combined tying and lifting member that ties the bundle together, i.e. the at least one combined tying and lifting member is wrapped around the bundle and its ends are joined together
Implementation Method 2
The stretch film is a highly stretchable film whose elastic recovery keeps items packed to it tightly bound

AI summary
A package (1) comprises a bundle of stretch film rolls (2) of equal length and having a longitudinal midpoint (M). Each stretch film roll (2) has a central longitudinal axis (A) and a stretch film (F) having side edges (E) wound around the central longitudinal axis (A). The central longitudinal axes (A) of the stretch film rolls (2) are parallel to each other. The package (1) comprises at least one combined tying and lifting member (4) that ties the bundle together. The combined tying and lifting member (4) is transversal in respect of the central longitudinal axes (A) of the stretch film rolls (2).
