Super Film Packaging Industry and Trade established in 1993, is part of the Sanko Group and is among Europe’s leading flexible packaging film manufacturer. The company currently has capacity for 70,000 tonnes (+ 60,000 tonnes planned investment in 2023) BOPP, 48,000 tonnes BOPET and 29,000 tonnes/year of metallized film with enhanced barrier protection. Super Film aims to provide all film types to its customers by increasing the product diversity within the Flexible Packaging films business and can offer special coated products, in addition to Turkey’s first and only extrusion (thermal) coating line.

The new machine incorporates a 700mm coating drum, which is the largest in the industry and unique to the Expert K5. The larger drum improves collection efficiency by 16%, which means less aluminium consumption resulting in maximum productivity and therefore production cost savings. It also includes a high rate source, which gives a higher speed of operation, and reduced distance between the boats gives better coating uniformity. Additionally, the EXPERT K5 has a wealth of other features to provide maximum machine uptime and consistent product quality. The AluBond process which was initially developed to increase metal adhesion and dyne level on the most commonly used film substrates but is said to be becoming the standard metallizing process for polyolefin based PP substrates due to its ability to increase barrier levels on these film types. 

The Bobst Hawkeye is an in-line optical density deposition control and defect monitoring system. At full metallizer speed, Hawkeye detects, counts and categorizes pinholes and other defects, alerting the operator so the issue can be rectified immediately resulting in less film waste.

Commenting on the investment Mr. Fahri Ozer, general manager and Gültekin Savaskan, board member and at Sanko Super Film said, “We have had a long relationship with Bobst beginning over 25 years ago and are 'very happy with our existing machines. When it was time to invest in a new metallizer, Bobst were our first choice due to our history and the advances they have made in their metallizing technology and processes in recent years. We are particularly impressed with the AluBond process which will enable us to produce higher barrier BOPP and CPP films to meet our customers' requirements.'
