ALPLA receives international awards for revolutionary development in extrusion blow moulding
ALPLA has been working with partners to develop foaming technology in extrusion blow moulding (EBM) for around four years. After receiving the Smart Packaging award from the Austrian government in 2014, this sustainable procedure has now also received the internationally renowned PackTheFuture and WorldStar awards.
The successful application of foaming technology in the production of EBM plastic bottles is the result of years of research and cooperation between ALPLA, Unilever and MuCell. In microcellular foaming technology, a gas is injected into the middle layer of the bottle wall. This creates bubbles in the material, similar to the structure of a honeycomb. Plastic consumption and weight are reduced by up to 15 per cent.
Resource- and cost-efficient
ALPLA has been producing shower gel bottles in Lübeck for the European market for Unilever using this procedure since 2014. According to its own figures, Unilever will save up to 275 tonnes of plastic per year across Europe for this product line. The technology will be installed in other ALPLA sites soon for customers in the body care and household products industries.
The process is a purely physical one and does not require any chemical additives. The bottles are therefore fully recyclable. 'The thickness of the material is reduced, but the thickness of the wall remains the same. The bottles therefore have practically the same high level of functionality in the bottling plants and during transportation and handling as conventional EBM bottles,' René Plattner, head of packaging management at ALPLA, explains. For the end user, the bottles look and function exactly the same.
Multiple award winner
ALPLA recently received two international awards for this technology: the PackTheFuture 2015 award in the Ecodesign category and the prestigious WorldStar award from the World Packaging Organisation in the Health & Beauty category. 'These industry awards highlight the potential of foaming for more sustainable packaging solutions,'says ALPLA CEO Günther Lehner, pleased with the success.
In November 2014, ALPLA won the special prize from ARA (Altstoff Recycling Austria AG) as part of the Austrian 'Smart Packaging' state prize.
