BOPP 70μm Film with Matte Effect
This biaxially oriented polypropylene (BOPP) film features excellent coating performance, superior dimensional stability, and outstanding printability. The matte finish reduces glossiness while enhancing texture and visual appeal.
Production Process
- Selection and pretreatment of polypropylene resin through drying and filtration
- Melting and extrusion into film followed by biaxial stretching for enhanced strength and toughness
- Heat treatment to stabilize size and properties before cooling and winding into rolls
Strict control of process parameters including extrusion temperature, stretching speed, and heat setting ensures consistent product quality.
BOPP vs CPP Film Comparison
BOPP film offers superior tensile strength, elasticity, impact resistance, and low permeability to air and water vapor due to its biaxial stretching process. CPP film, with less molecular orientation, provides greater flexibility and transparency suitable for food wrapping and agricultural applications.
Applications
Matte BOPP film is versatile for packaging, printing, home decoration, automotive interiors, electronic products, and signage. It enhances product appearance by creating softer, more natural printed patterns and improving visual experiences across various applications.
