How does low friction metallized CPP film achieve a low friction coefficient?

Nov 22,2023

The low friction coefficient of metallized CPP film is achieved through a combination of factors and specialized manufacturing techniques. Let's explore how this innovative film manages to attain its low friction characteristics.
Firstly, CPP stands for Cast Polypropylene, which is a type of plastic film known for its excellent clarity, strength, and flexibility. CPP films are widely used in packaging due to their versatility and cost-effectiveness. 
Metallization, on the other hand, involves depositing a thin layer of metal, typically aluminum, onto the surface of the CPP film through a vacuum deposition process. This metallized layer not only provides an attractive appearance but also enhances the film's barrier properties, such as moisture and gas resistance.
To achieve a low friction coefficient, the metallized CPP film undergoes an additional treatment process. During this process, the film is treated with special additives that reduce the friction between the film and other surfaces, such as manufacturing equipment or other packaging materials.
These additives, known as slip agents or lubricants, form a thin, invisible layer on the film's surface, creating a smoother contact surface with reduced adhesion forces. As a result, the film can slide easily and smoothly, minimizing the risk of sticking, blocking, or jamming during packaging processes, such as high-speed filling or automated handling.
Additionally, the low friction properties of metallized CPP films offer several practical benefits. First and foremost, they reduce the amount of force required to handle the film, ensuring smoother manufacturing operations and reducing the risk of damage or tears during processing.
Furthermore, the low friction coefficient diminishes the static charge build-up on the film's surface. This is particularly important in industries where static electricity can be a major concern, as it can attract dust and particles or cause electrical hazards.
Overall, the utilization of low friction metallized CPP films in the packaging industry revolutionizes efficiency, productivity, and product quality. The reduced friction allows for faster production speeds, increased throughput, and improved overall performance. Additionally, the enhanced functionality of such films aids in maintaining the integrity and appearance of packaged products throughout their lifecycle.
As packaging demands continue to grow, manufacturers and converters are increasingly turning to low friction metallized CPP films as a reliable solution for delivering packaging with improved functionality, efficiency, and customer satisfaction.
