Corona Treater Station Corona Nip Roller Used For BOPP BOPET Production Line

Basis Information

Corona Nip Roller used in pull roll stand of various polyfilm production lines, the corona nip roller works together with the corona roller and pull roll stand cooling roller. Corona nip roller surface coated synthetic rubber or EPDM rubber with good resilience and excellent ozone resistance, anti-static and aging resistant performance, and its roller surface can be machined into the crowing in different values by the numerical control crowned machine as required. The hardness of the synthetic rubber or EPDM generally 55-65 Shore A, after formula processing, the ruber can withstand temperatures up to 130 degrees Celsius.

Corona Nip Roller Specification

Corona Nip Roller Features

Surface Quality: The corona nip rollers have a flat, smooth, centered, and round surface to ensure continuous sealing against each other.

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

Trapping Air: The nip rollers are designed to trap air between corona roller and corona nip roller.

Roller Repair: If the rubber 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.

Corona Nip Roller Benefits

Good stability under pressure at elevated temperature.

Good abrasion and tear resistance.

Very good resistance to acid and alkaline products and to ozone.

Moderate resistance to polar solvents - not suited for contact with aromatic solvents - moderate oil resistance.

Good consistent speed, the primary corona nip rollers in the polyfilm production process ensure a consistent speed, which directly affects film quality and profitability.

Good film quality, the flat and smooth surface of the nip rollers prevents defects such as creasing or film damage caused by crushing the folds.

Uniform pressure, the corona nip rollers apply uniform pressure across the film, ensuring consistent and equal roll speed and uniform pressure between the rollers.
