Engineered for Every Orientation.
BOPP Film Extrusion
Masterbatch Solutions.
High-performance PP-carrier masterbatches formulated for biaxially oriented polypropylene film — precision chemistry that survives the tenter frame.
Tenter Frame Process
From Resin
to Oriented Film.
Isotactic PP homopolymer or random copolymer is melt-extruded through a flat die, cast onto a precision chill roll, then biaxially stretched — first longitudinally (MDO) and transversely (TDO) — imparting superior tensile strength, stiffness, and moisture barrier properties. Masterbatches must survive this full thermal and mechanical sequence without causing film breaks, haze, or die lines.
Sequential Biaxial Orientation
Industrial-scale LISIM and tenter frame lines achieving 4–6× biaxial draw ratios

Critical Additive Systems
The Right Masterbatch
Changes Everything.
In BOPP film processing, masterbatches are compounded in PP homopolymer or PE carrier resin at 1–5% letdown ratio. Carrier MFI must match the base resin for uniform dispersion. Pigment D50 must be below 1μm to prevent stress concentration and film breaks during biaxial stretching.
White TiO2 Masterbatch
TiO₂-based (rutile, surface-treated) in PP carrier at 50–70% loading. Delivers high hiding power, CIE whiteness ≥90, and uniform optical density for label and synthetic paper BOPP films.
Slip & Anti-Block MB
Erucamide / oleamide + SiO₂ or CaCO₃ antiblock in PP/LLDPE carrier. Reduces COF to 0.15–0.30 for high-speed packaging converting and prevents film fusion during roll storage.
Antistatic Masterbatch
GMS (glycerol monostearate) and amine-based antistats migrate to film surface, dissipating charge buildup in high-speed slitting, lamination, and FFS packaging operations.
UV Stabilizer (HALS + UVA)
Hindered Amine Light Stabilizers (HALS) combined with benzotriazole UV absorbers in PP carrier. Protects film from photodegradation — mandatory for outdoor label, agricultural, and extended shelf-life packaging films.
PP vs PE Carrier
Carrier Resin
Matters Most.
For BOPP, PP homopolymer carrier (MFI 10–25) is the gold standard — integrating without phase separation during biaxial stretching. PE-carrier masterbatches introduce soft phase domains that risk stress whitening or delamination at high draw ratios. Use PE carrier only where migration behaviour of slip/antistatic agents is the primary functional requirement.
BOPP Film End Products
Films That Power
Modern Packaging.
BOPP is the world's dominant flexible packaging substrate — combining high stiffness-to-weight ratio, excellent moisture barrier (WVTR <0.5 g/m²/day), and outstanding optical clarity. Each end product demands a precisely tailored masterbatch system.
