We tested the client’s product packaging using stretchhood technology in a Lachenmeier hood-type packaging machine.
Project Context
The client manufactures glass items, including vases, which are stacked on a pallet in layers with paper dividers.
The solution used so far utilized stabilizing corners, but in practice, problems arose:
- corner breakage in the dividers,
- decreased load stability,
- risk of product movement on the pallet,
- increased risk of damage during transport.
Challenge
A key goal was to research a packaging method that would increase the stability of glass products and reduce load oscillations, while simplifying the packaging process.
For testing, we decided to recreate the existing packaging concept, eliminating the stabilizing corners. Among other things, we tested a double-wrapping system, which is designed to secure the load and protect it during transport.
Pallet foiling test
During testing, we focused on developing solutions that would reduce oscillations and the increased risk of product damage. By eliminating corners, we focused on a suitable wrapping system that would effectively stabilize the load during transport. Ultimately, the two-stage process proved successful.
1. Stabilizing layer – foil sleeve
The first step in the process is to create a tight sleeve from 60 µm-thick film, which holds the load in the shape defined during palletization.
To reduce material consumption and packaging costs:
- the sleeve is left open at the top,
- additional film overhang is added to the corners of the edges to prevent excessive pressure from being applied to the load.
The sleeve provides high stability, further enhanced by relatively thick-walled product separation grids.
2. Protective layer – foil hood
The second step involves applying a thicker 80 µm foil hood to the pre-stabilized pallet.
The hood serves several functions:
it additionally stabilizes the entire stack.
it binds the stabilized load to the pallet,
it protects the products from external factors,
it allows for the removal of the outer layer after transport, which is particularly important for internal logistics in clean areas,
Effects for the client
The solution used creates a double load-locking system that effectively “freezes” the pallet structure.
This allows:
- reduced product oscillations and resonance during transport,
- stabilized the columnar arrangement of glass products,
- reduced the risk of damage resulting from load movement.
Packaging Economic Results
For an 800 x 1200 mm pallet with a height of 1250 mm (including the carrier), we obtained the following material consumption:
- Film sleeve: 265 g
- Film hood: 418 g
Tests were conducted using Lintegra film.
Test experience and process analysis indicate that the customer’s final solution will be optimized for a machine that allows for the alternating use of two different films.
