WORLD TOUR EUROPE Business, Strategies & Markets Innovation key to future for Serbian processors By Robert Colvin Barrier-film processor Spektar (Gornji Milanovac), after installing a 7-layer, biaxially oriented, blown shrink-wrap line from Kuhne Anlagebau (Sankt Augustin, Germany) five years ago (April 2004 MPW, p. 45), has embarked on a project offering even higher barrier. The processor was named 2007 Exporter of the Year by the government for its innovative packaging products, which are sent to markets throughout Europe, the surrounding Balkan states of the former Yugoslavia, Russia/CIS countries, and even North America, where the processor is eager to find a distributor. Spektar owner Zoran Dordevic, together with his two sons, has opted for a 9-layer, triple bubble system, producing web in 25-100-μm tolerances, on a line delivered from Kuhne but with its design based on Spektar’s 5- and 7-layer production experience, he says. The new unit allows up to 50% better shrink properties for packaging of meats and cheese. Son Petar Dordevic says the unit will complement the company’s offering since 7-layer film (40-100 μm) produced there provides better puncture resistance for packaging such things as fresh meat with sharp bones. “We want to be able to offer customers the optimum choice of film structures to match their products,” he says. Petar Dordevic adds The first 10,000 injection molded instantaneous hot water heaters left Serbian processor RPC Pesovic for delivery to a South African building developer in April. Although Serbia is a small European country, big things are happening there in plastics processing as discovered on a recent return visit by Modern Plastics. that the 9-layer line also yields substantial future possibilities. For example, for cheese packaging that Spektar started targeting last year, he foresees a 9-layer film with a selective barrier, permitting CO 2 that cheeses produce to be evacuated while preventing oxygen ingress. Better-controlled barrier for poultry packaging is also possible. During the last two years the company invested about €5 million not only in the 9-layer line but also in a new building addition to house the unit and an 8+8 color flexographic printer from Windmöller & Hölscher (Lengerich, Germany), delivered in June of this year. The expansion also required the company to meet new fire regulations and since the local community could not guarantee enough water delivery in case of fire, Spektar was required to install water storage on the premises Award-winning designer and injection molder P. Peshovich, owner of RPC Pesovic, demonstrates his injection molded, tankless, energy-saving water heater, recently delivered to a South African customer. in case of a blaze. Zoran Dordevic decided if he had to include that, then the storage should be in the form of a swimming pool, which staff and families use after work. At blown-film processor Bel Plast (Bela Zemlja), Manager Sanja Spijunovic saw enough growth potential to install a new 3-layer line from Kuhne primarily dedicated to linear low-density polyethylene-based stretch-hood production for pallet wrap targeted at such products as cement bags, cinder blocks, and roofing tiles. The €2 million line with inline printing is also versatile enough, says Spijunovic, that it can be used to produce biodegradable shopping bags for Serbia’s largest supermarket chain, Delta. Film line troubleshooting is handled by remote diagnostics. At processor and toolmaker RPC Pesovic (Simanovci), a new complement to the existing injection molded water- and energy-saving sanitary fixtures line is a plastic instantaneous water heater. Originally RPC Pesovic was only to supply the fixtures but its co-vendor for hot water boilers was incapable of supplying 38 JULY/AUGUST 2009 • MODERN PLASTICS WORLDWIDE mpw.plasticstoday.com

Our unit eliminates that. ” came up with a solution in 30 days and another 90 days was necessary to build the required molds and stamping tools.” The result is a mini (500g) injection molded tankless water heater that is said to waste no energy. mpw.plasticstoday.com EUROPE Business, Strategies & Markets Unlike insulated heaters that heat up water and hold it warm for use, this unit provides instant warm water on demand. “Generally a [traditional] water heater wastes up to 1000 kWh of energy just keeping warm water available. Our unit eliminates that—as well as the wait until the warm water reaches the faucet through the pipes (an average of 3.5L loss), since this unit is installed directly above the faucet for a shower, tub, or wash basin,” he says. Development of this injection molded project, using a blend of engineering resins to cope with the 70-80°C water temperatures, started last November, and delivery of the first 10,000 units to the South African building and construction customer took place in April.

The company is now seeking certification of this unit so that it can be marketed throughout the European Union. MPW MODERN PLASTICS WORLDWIDE • JULY/AUGUST 2009 39
