The manufacturing process of BOPP film involves several steps, including extrusion, orientation, and coating. In this section, we will discuss each of these steps in detail.

Extrusion

The first step in the manufacturing process of BOPP film is extrusion. This involves melting polypropylene resin pellets and extruding them through a flat die to form a thin sheet of plastic. The thickness of the sheet can be adjusted by changing the gap between the die and the cooling rollers. The molten plastic is then cooled rapidly to solidify it.

Orientation

After extrusion, the clear BOPP film is stretched in both the machine direction (MD) and transverse direction (TD) to orient the polymer molecules and improve the mechanical properties of the film. This process is called biaxial orientation and is achieved by passing the film through a series of heated rollers that are set at different speeds and temperatures. The stretching process aligns the polymer molecules in the direction of the stretch, which increases the tensile strength and clarity of the film.

Coating

The final step in the manufacturing process of clear BOPP film is coating. This involves applying a thin layer of adhesive or coating material to one or both sides of the film to improve its barrier properties, printability, or other performance characteristics. Coating can be done by various methods, including gravure coating, flexographic coating, and extrusion coating.

In summary, the manufacturing process of clear BOPP film involves extrusion, orientation, and coating. Each of these steps plays a crucial role in determining the properties and performance of the final product.
