Progressive starch products for industry from Finland

24.08.2004


New raw materials are proving a technological leap in packaging.

VTT Technical Research Centre of Finland has developed new products from potatoes and grain for the packaging, paper, construction and medical technology industries. The new glues and paper coatings developed from starch are economical, durable and can be completely recycled. They also enable lighter packaging products. The starch products and their manufacturing methods signify an enormous step forward for the packaging and paper industries. The new starch products can also be utilised in pharmaceutical products as they make it possible to regulate the release of substances into the body.

The new raw materials developed by VTT are an immense technological leap forward for the packaging field. They are appropriate for use as raw materials in glues for the construction industry. The new starch products can be used especially to replace current synthetic raw materials for glues, which are difficult to recycle.



Earlier products made from natural starch were extremely hard and brittle. Moreover, the dry material content was generally only 50 per cent, which in products containing fibres such as board gives rise to warping and swelling of the fibres.

With the new VTT method the potato and grain starch is broken down into minute parts, which are then refined into the new starch products. The properties of these products can be modified in many ways to suit the end use. The starch products can be further refined into 100 per cent hot melt adhesives and water dispersion glues with a dry material content of as much as 80 per cent. The new glues based on natural materials can be used for lightweight packages which retain their strength and withstand grease well. Furthermore, the material and energy costs of industrial manufacture can be reduced , likewise the burden on the environment.

The new starch products and their manufacturing methods have been developed at the VTT Rajamaeki pilot facility to be suitable for industrial production. The results have led to three applications for patents and the experimental production of new packaging material in an industrial plant. VTT, Tekes, Helsinki University of Technology, the University of Oulu and several industrial concerns have participated in the development work.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
