Perfect packaging

01.12.2004


Corrugated cardboard is an excellent packaging material that is widely used for transporting, storing and protecting goods. Through the new process developed by EUREKA project E! 1929 FACTORY FOLDHEX, corrugated cardboard can be transformed into a new honeycomb core that offers reduced weight, uses less raw material and achieves better crash absorption and higher compression resistance than double flute corrugated cardboard.

Honeycomb cores are already used in a variety of applications, including the aerospace and automotive industries, because of their outstanding performance in providing structural support and reducing weight. They are also recyclable and can even be produced from recycled paper. “However, current paper honeycomb production involves many distinct steps, making it too slow and too costly to target the corrugated cardboard market,” explains Jochen Pflug from the Department of Metallurgy and Materials Engineering at the project’s lead partner, the Katholieke Universiteit Leuven (K.U.Leuven).

To overcome this weakness, the project partners created an innovative and cost-effective process to produce the packaging material from a single continuous sheet of corrugated cardboard.



The new folded honeycomb material, developed and patented by K.U.Leuven, is produced by successive in-line slitting, rotation and glueing steps, and can be produced at a rate of 100 metres per minute. This allows for a continuous high-speed, low-cost production process that can compete in the double flute corrugated cardboard market worth €4.5 billion a year in Europe alone.

In addition to the new packaging material, the project partners have sandwiched thin (5 -10 mm), cost-efficient paper honeycombs between natural fibre mat skins for use in structural applications such as in cars and furniture – wherever there is a need for cost and weight savings. “The honeycombs also have good impact properties and can be recycled,” adds Pflug.

Despite the proven production speeds of the new honeycomb material, the transformation process for the structural materials currently works off-line, and with a board width limited to 1200 mm. Although production is already economically viable, work is continuing to optimise production and maximise profitability.

A spin-off company is expected to market the technology and to produce the structural honeycomb products. “Being a EUREKA project helped bring together companies from many different industrial sectors to develop new materials with many different potential applications,” says Pflug.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
