BOPP 50micron Film, Lightweight, Moisture-proof, High Mechanical Strength, Good Dimensional Stability, Good Printability

<General production process of BOPP film>

1. Raw material preparation:

    Selecting suitable polypropylene resin and performing pretreatment, such as drying and filtration.

2. Extrusion:

    Melting the pretreated polypropylene resin and extruding it into a film.

3. Orientation:

    Stretching the extruded film biaxially to orient the molecular chains and improve the film's strength and toughness.

4. Heat setting:

    Heat treating the stretched film to stabilize its size and properties.

5. Cooling:

    Cooling the heat-set film to an appropriate temperature.

6. Winding:

    Winding the cooled film into rolls for storage and transportation.

The above steps outline the general process of BOPP film production, and adjustments or optimizations may be made depending on specific production circumstances. Additionally, various process parameters such as extrusion temperature, stretching speed, heat setting temperature

and time, etc. need to be controlled during the production process to ensure product quality.

<Main difference between BOPP and CPP film>

The main differences between biaxially oriented polypropylene (BOPP) film and cast polypropylene (CPP) film are their production processes

and performance characteristics. BOPP film is stretched biaxially during production to improve its strength and toughness, while CPP film is not stretched and has less molecular orientation.

BOPP film typically has higher tensile strength, elasticity, and impact resistance, as well as lower permeability to air and water vapor.

BOPP film is commonly used in applications that require high strength and toughness, such as packaging and capacitor films,

while CPP film is more suitable for applications that require flexibility and transparency, such as food wrap and agricultural films.

BOPP film has a broader thickness range and can be produced in both thin and thick films, while CPP film typically has a narrower thickness range and is thinner overall.

<The main application scenarios of Matte BOPP film> 

1. Packaging:

    Matte BOPP film is used in the packaging of food, pharmaceuticals, cosmetics, and other products to reduce glossiness, increase texture,

    and enhance product quality.

2. Printing:

    Matte BOPP film is used for surface treatment of printed materials to make the printed patterns more soft and natural, improving printing quality.

3. Home decor:

    Matte BOPP film is used in home decor applications such as curtains and wallpaper to create a matte effect and provide a comfortable, warm

    atmosphere.

4. Electronic products:

    Matte BOPP film is used to cover the surface of electronic products such as mobile phones, tablets, etc. to reduce reflection and improve visual

    experience.

5. Automotive interior:

    Matte BOPP film is used in automotive interior applications such as instrument panels and center consoles to reduce glossiness, increase

    texture, and enhance comfort.

6. Signage:

    Matte BOPP film is used to make various signs and signboards, making the markings clearer and more eye-catching.

    These are just some common application scenarios, and the selection of matte BOPP film will depend on specific requirements and product

    characteristics. Using matte BOPP film can improve the appearance of products, enhance product texture and value.
