Bangladesh-based Kalyar Replica has purchased its first metallizer to bring the metalizing process for high barrier films in-house. The Vision K5 1650 mm vacuum metallizer should be commissioned and in production in the next month (April 2021). It is equipped with Bobst’s AluBond to produce CPP and BOPP with high barrier and high adhesion levels and the Bobst Hawkeye inspection and quality control system for pinholes and other defects.
Established in 2008, Kalyar Replica is one of the leading flexible packaging companies in Bangladesh. With a highly experienced team and modern infrastructure and technology, the company specializes in providing its customers with almost defect-free products in competitive time frames.
Bobst AluBond on polyolefins
The Bobst Vision K5 purchased by Kalyar is equipped to handle various film types, including heat-sensitive and thin gauge films. The company will use it for processing the latest specifications of polyolefins.
Bobst’s AluBond is well known in the industry as a metalizing process for polyolefin-based substrates. It was initially developed to increase metal adhesion on the most commonly used substrates when applied to CPP and BOPP films. Moreover, AluBond provides enhancement of oxygen (OTR) and water vapor (WVTR) barrier performance in addition to its superior adhesion properties. With the latest market demands for sustainable packaging films, AluBond is also being used to produce high barrier metalized CPP and BOPP mono-material laminates.
The new K5 machine ordered by Kalyar also includes the Bobst Hawkeye in-line optical density deposition control and defect monitoring system. Hawkeye detects, counts, and categorizes pinholes and other defects at full metallizer speed, alerting the operator so the issues can be rectified immediately, resulting in less film and metal waste.
Commenting on the purchase, Ms. Tasneem Sinha, managing director of Kalyar Replica, said, “When we decided to purchase our first metallizer, we needed a machine which could process a range of substrates. We chose Bobst and the Vision K5 as it can handle heat-sensitive films and for the AluBond process, which will enable us to produce CPP and BOPP films with both high barrier and high adhesion. The machine will be arriving very soon, and we look forward to it being installed and running in the factory.”
