BOPP/CPP Film Masterbatch for Plastic Packaging & Films

Silicone masterbatch powder and pellets in film packaging production facility

High COF that stops film lines, blocking between layers, hazy films and heat-seal failures — film producers lose tons of output to these problems every month. Xiangxi's BOPP/CPP film masterbatch is a silicone-based slip and surface-performance additive system for packaging films, delivering stable coefficient of friction (COF), better release and optical clarity, with a low-migration formulation designed for food-packaging compliance.

Key Challenges in Packaging Films

Unstable coefficient of friction — films must run at high speed on FFS machines and converters' lines without sticking or slipping.
Blocking and poor release — layers stick in the wound roll, causing wrinkles and web breaks.
Migration and haze — conventional slip agents bloom over time, causing haze and print/seal problems.
Food-contact compliance — additives must meet low-migration requirements (e.g., EU REACH expectations, 1,000 ppm thresholds for silicone additives).
High-speed converting — printing, laminating and bag-making all demand consistent film surface properties.

1. BOPP/CPP Film Masterbatch

Our dedicated BOPP/CPP film masterbatch uses ultra-high molecular weight siloxane to reduce surface friction and improve release. Because the siloxane is high molecular weight and finely dispersed, it provides stable long-term COF without the blooming and haze typical of erucamide/oleamide-only systems.

2. Silicone Masterbatch for PE Films and Flexible Packaging

For PE sealing layers and flexible packaging, our silicone masterbatch improves slip, anti-blocking and processing stability, and can be combined with standard slip/anti-block packages for a tuned COF profile.

Applications & Benefits

Film Application	Benefit
BOPP food packaging film	Stable COF for high-speed FFS lines; clear film without haze increase
CPP sealing and cast films	Better release, less blocking in rolls, consistent heat-seal quality
Label and tape films	Smooth surface for printing and die-cutting; controlled friction
Flexible PE packaging	Anti-blocking and slip tuned to converter requirements

Why Film Producers Choose Xiangxi

Xiamen Xiangxi New Material Co., Ltd. is a national-level high-tech enterprise founded in 2016, with 8+ production lines, 20,000+ tons/year capacity, 28+ patents and ISO9001-managed production. Our film masterbatches are designed for low migration to support REACH/RoHS compliance expectations in food packaging, and our engineers run line-side trials to fix dosage (typically 1–3%) against your COF target and converting equipment.

FAQ — Packaging & Films

How does silicone-based film masterbatch differ from traditional amide slip agents?

Amides work by migrating to the surface, which causes time-dependent COF changes, haze and print issues. High-molecular-weight siloxane stays put, giving stable friction and optical properties over time.

Will it affect film transparency or heat sealing?

When used at the recommended 1–3%, haze increase is negligible and heat-seal performance is maintained; we validate both on your film line during trial.

Is it suitable for food packaging?

Yes. The formulation is low-migration and designed to support food-packaging compliance programs, including REACH expectations for silicone additives.
