Since the late 1970s, the BOPP industry has continuously enriched its product varieties, adding color to our lives. BOPP products are classified by different uses into: Gloss Film, Matte Film, Pearl Film, Cover Film, Aluminum-plated Film, Tape Film, Bag-making Film, Heat-seal Film, Laser Film, Anti-fog Film, and more.
Main BOPP Film Categories
Gloss Film (光膜)
Primarily used for printing and packaging. Divided into thick film (>25μ) and thin film (<19μ).
Matte Film (消光膜)
Also called亚光膜, achieves effect through light absorption and scattering. Used in high-end packaging.
Pearl Film (珠光膜)
3-layer co-extruded stretched film with heat-seal layer. Density <0.68, commonly used in food packaging.
Cover Film (盖光膜)
Usually <18μ thin gloss film with double-sided corona treatment.
Aluminum-plated Film (镀铝膜)
Commonly based on BOPET and CPP substrates. BOPP aluminum-plating is relatively rare in China.
Laser Film (镭射膜)
Transparent BOPP film with moldable function layer. Used for anti-counterfeiting packaging and luxury decoration.
Detailed Applications
Gloss Film
Ordinary gloss film is mainly used for printing and packaging. Thick film refers to thickness above 25μ, while thin film refers to below 19μ.
Matte Film
Also called亚光膜, it achieves effect through light absorption and scattering, generally enhancing the grade of printed surfaces. However, the price is relatively high, and domestic manufacturers are few. It is often used in boxed food or high-end packaging. Matte film usually has no heat-seal layer, so it is often used in combination with other films (such as CPP, BOPET).
Pearl Film
Mostly 3-layer co-extruded stretched film with a heat-seal layer on the surface. Commonly seen in chopstick bags. Pearl film has a density mostly controlled below 0.68, which helps save costs. Pearl film presents a white, opaque pearl effect with certain light-blocking ability, protecting light-sensitive products.
Laser Film
It is a transparent BOPP film with a moldable function layer. No additional coating is needed for molding. After aluminum plating or蒸镀 medium, it is used for anti-counterfeiting packaging, or combined with cardboard for cigarette, pharmaceutical, and food packaging boxes. Relatively few domestic manufacturers, generally used for high-end anti-counterfeiting and decorative packaging.
Future Outlook
BOPP film still has many high-end films such as capacitor films and custom films. It is expected that under the environment of competition pressure and shrinking profits for mass products, BOPP film varieties and new films will continue to develop, adding momentum to our packaging world.
