45 Extrusion International 2/2021 CHINAPLAS 2021 “We from SML would say that machin- ery, that is reliably delivering premium- quality film in constantly high volumes isaprerequisite.Butat theend, thefinal key to commercial success are produc- tivity and low unit costs,” says Huang Zefeng, Sales Manager Cast Film Extru- sion, China. This is why SML is continu- ously further-developing the widths of its CPP lines in accordance with raising maximum output quantities. This hap- pens especially with regard to the mar- kets in Asia, where SML premium CPP lines with a width of more than 5 me- cess, are additionally equipped with disc or candle filters. These large area filters are capable of eliminating even small gel particles. This avoids defects in the film at the following metallis- ing process. For extra-wide CPP cast film lines, SML recommends its turret winder W6000 with a maximum outer roll diameter of 1,300 mm. Bigger roll diameters are a major boost in produc- tion efficiency for the manufacturing of metallising CPP films. Due to lon- ger running times at the metalliser, there are less roll changes with less film waste. SML’s turret winder W6000 en- ables a roll length of 50,000 meters or – 50 km! – of 25 μ m film. Quality, reliability, service SML is a globally reputated technol- ogy leader for extrusion systems with branch offices in Beijing, China and Kuala Lumpur, Malaysia since more than 25 years. Machinery developed and manufactured from SML stand for high standards in terms of reliability, longevity and output quality. Partner- ing with SML provides you a reliable project implementation and a proven track record of adhering to the agreed times, costs, and performance values. Our representative office in Beijing offers comprehensive support to cus- tomers all over China: especially when it comes to in-depth technical informa- tion about our products, the flexible organization of on-site services by SML technicians located in China or the fast shipments of wear and spare-parts. SML Maschinengesellschaft mbH Gewerbepark Ost 32, A-4846 Redlham, Austria www.sml.at, www.sml.at/zh-hant ters are inoperation for years. Recently, SML sold two extra-wide CPP lines with film widths of 6.5 meters and with an output-capacity of up to 20,000 metric tons per year to Asian customers. Bringing unit-costs down Compared to other lines for CPP film, SML’s extra-wide CPP lines have a con- siderably lower ratio of edge trims. Additionally, the inline feedback of the edge trim scrap by a scraptruder essentially contributes to its commer- cial success. Labour costs per unit on extra-wide lines are also lower, as they do not require additional personnel to produce higher volumes. And also in terms of power consumption (kW/kg), extra-wide lines clearly beat smaller CPP filmmachinery. CPP fi lms for metallisation: perfect conditions for premium qualities A frequent extruder-combination in SML’s extra-wide CPP lines is Ø 180/90/90/90/90mm. Extruders from SML, which produce CPP films for met- allisation in a subsequent separate pro- When it comes the production of CPP film, i. e. for the metallised packaging of food and textiles, there is a clear trend towards high-volume production. But is the ability of tomanufacture high quantities at good qualities alone enough to get the edge in today’s markets?
