K2 Amp K3 Plus

K2 & K3 Plus Seamer

The new PLUS series is the most advanced seamer in the industry. Karlville has once again innovated by launching the third generation of seamers which eliminates the forming tool. This new design makes the most operator friendly machine available, facilitating training with the most automated machine on the market. The K2 utilizes a brake on the unwind the K3 is motorized. The machine have 3 tension zones, which allows for a dedicated tension zone for the forming section for better lay flat control. The unwind tension zone is now free to add innovations like laser integration or pin hole perforation while the film is flat.

The PLUS offers a long list of advantages that solve the issues that come with the previous generation of machines that use forming tools. This new machine promises to revolutionize the way shrink sleeves are converted.

Make sure you see it before making any decisions.
