How Is BOPP Film Made?

The production of BOPP film is a meticulous process that transforms isotactic polypropylene into a functional and versatile packaging material through a series of controlled steps, ensuring the film’s desired properties and quality.

Raw Material Feeding

The manufacture of BOPP film begins with feeding raw materials. The isotactic polypropylene, characterized by its uniform structure, is introduced into the production line. Here, it will be melted and formed into a thin film with robust tensile strength, an essential characteristic for ensuring the film’s durability.


During the extrusion phase, the molten polypropylene is pressed through a flat die, shaping it into the preliminary form of a film. This stage is critical for establishing a consistent thickness and width, which are the foundational attributes of the film’s structural integrity.

The Foil Cooling

Post-extrusion, the hot film enters the cooling phase, rapidly chilling using a water-cooled roller. The rapid cooling solidifies the film and locks in the desired mechanical properties, preparing it for the subsequent orientation processes.

Machine Direction Orientation

Machine direction orientation (MDO) is a pivotal step in the production of BOPP films. The film is stretched in the direction of the machine line, realigning the polymer chains and enhancing properties such as stiffness and tensile strength. This orientation is crucial for the film’s functionality in packaging applications.

Transverse Direction Orientation

Following MDO, the film passes through the transverse direction orientation (TDO) stage, which is stretched perpendicular to the machine direction. This step further improves the film’s mechanical properties and ensur

es balanced strength across both axes.

Thickness Measurement

Constant monitoring of the BOPP film density is performed to ensure uniformity and adherence to specifications. Precision instruments measure the film throughout production, allowing for real-time adjustments to maintain quality control.

Flame Treatment

Flame treatment is applied to BOPP films to increase their surface energy, allowing for better adhesion of inks and coatings. This process involves passing the film over a controlled flame, subtly altering the surface characteristics by oxidizing the outermost polymer chains.

Reel Winding

Once the film has been treated and reached the desired thickness, it is wound onto large reels. This stage marks the preparation for the film’s distribution and subsequent use in various packaging applications.

Film Measurement

Critical to maintaining consistent quality, the film for packaging is measured for various properties such as thickness, width, and flatness. These measurements ensure that the film meets the rigorous standards required for its diverse uses in the packaging industry.
