Rubber Coated MDO Nip Roller for BOPP and BOPET film production line

Silicon Rubber Coated MDO Nip Roller offers several features and benefits specifically designed for BOPP BOPET and PP casting films production line.

Features of MDO Nip Roller for Films
Surface Quality: The MDO nip rollers have a flat, smooth, centered, and round surface to ensure continuous sealing against plastic film and MDO nip roller surface.

Durometer: The covering on the MDO nip roller is designed to be soft, allowing it to conform well to the plastic film passing between the rollers, especially folded edges or gusseted films.

Trapping Air: The nip rollers are designed to trap air inside the bubble of the plastic film, especially in conventional non-IBC air ring cooling systems.

Roller Repair: If the MDO nip roller's surface becomes worn or damaged, it can be repaired by regrinding or recovering, although this may result in substantial downtime on the production line.

Benefits of MDO Nip Roller for Films
Consistent Speed: The primary nip rollers in the blown-film process ensure a consistent speed, which directly affects film quality and profitability.

Bubble Stability: By trapping air inside the bubble, the nip rollers help maintain bubble stability during the film production process.

Film Quality: The flat and smooth surface of the MDO nip rollers prevents defects such as creasing or film damage caused by crushing the folds.

Uniform Pressure: The MDO nip rollers apply uniform pressure across the film, ensuring consistent and equal roll speed and uniform pressure between the rollers.

Defect Detection: The use of nip impression films, such as Fujifilm Prescale, can help diagnose issues related to roller alignment, parallelism, and pressure load distribution.
