Chill Roller for BOPP/BOPET Packaging Film

                                         Chill Roller for BOPP/BOPET Packaging Film

Chill Roller for BOPP/BOPET Packaging Film is an essential component in the film production of BOPP (Biaxially Oriented Polypropylene), BOPET, BOPA and BSF packaging film. It plays a crucial role in the cooling and solidification of the molten polymer as it is transformed into a thin film. The chill roller helps to ensure uniform thickness, flatness, and quality of the films.

Function of Chill Roller:

1. Quenching: Chill rollers rapidly cool down the molten polymer, causing it to solidify and transform into a cast film.

2. Temperature Control: Chill rollers help maintain the desired temperature of the film during the cooling process, ensuring proper crystallization and mechanical properties.

3. Flatness and Thickness Control: Chill rollers contribute to achieving uniform thickness and flatness of the BOPP film, resulting in high-quality packaging material.

Features and Specifications:

1. Material: Chill rollers are typically made of materials with excellent thermal conductivity, such as steel or aluminum, to efficiently transfer heat from the film.

2. Surface Finish: The surface of the chill roller is carefully engineered to provide the desired level of contact and cooling efficiency. It may have a polished or textured surface, depending on the specific requirements of the film.

3. Diameter and Length: Chill rollers come in various diameters and lengths, depending on the width and speed of the film production line.

4. Cooling Medium: Chill rollers are often hollow and internally cooled using water or other cooling fluids to maintain the desired temperature.

5. Coating: In some cases, chill rollers may have specialized coatings or treatments to enhance their performance, such as chrome plating or thermal spraying.

6. Ra 0.002um to 20um.

7. Diameter: Max 3.2m
