Fully Automatic Drum Type Metalized Film Slitting Machine
Precision Slitting for Sensitive Metalized Film Rolls
The Fully Automatic Drum Type Metalized Film Slitting Machine is built to slit large rolls of metalized films into smaller reels without causing any damage to the delicate metal coating on the films. It is important that the metalized films are handled with care since factors such as excessive tension, friction, and even poor winding may result in poor quality on the film. This machine performs all the processes from automatic unwinding of the film, guidance of the web, slitting, tension control, to drum rewinding in order to ensure that the process runs smoothly. This machine is suited to metalized PET films, metalized BOPP films, metalized coated films, printed metalized films, and laminate films.

Protecting the Metalized Surface During Slitting
The thin metallic coating on metalized film can be sensitive to scratches, rubbing, creasing, and excessive web pressure. For this reason, controlled material handling is important from the unwind section through to the finished reels.
The machine maintains an organized web path so the material passes through the cutting section with minimum unnecessary movement. Accurate knife positioning helps create the required reel widths while controlled web guidance keeps the film aligned during continuous operation.
Proper adjustment according to film thickness, coating characteristics, roll width, and surface condition helps preserve the visual and functional quality of the metalized layer during conversion.
Automatic Tension Control as Roll Diameter Changes
Metalized film needs to maintain a constant tension in the whole roll and not just at the beginning. With the parent roll getting smaller and the final roll getting bigger, the winding conditions are constantly changing.
The automatic control system aids in adjusting the changing conditions in order to keep the web steady as it passes through the machine. Maintaining adequate tension ensures that there are no wrinkles, web wandering, stretching, slack wind, or excessive compression.
Maintaining consistent motion of material becomes important in case of a long production run because manual adjustment interrupts production.
Drum Winding for Stable Metalized Film Reels
After slitting, each narrow web must be rewound without disturbing its edges or reflective surface. The drum-supported winding system provides controlled support as reel diameter gradually increases.
Balanced contact during rewinding helps the layers settle evenly around the core and supports a consistent reel profile. This can reduce problems such as telescoping, uneven edges, loose layers, and irregular roll build-up.
Properly formed reels are easier to handle during storage and transportation and can be prepared for subsequent lamination, printing, pouch making, label conversion, or other compatible packaging processes.
