Slip Masterbatch
Lower COF. Cleaner bag-making. No stick at the seal jaw.
Slip Masterbatch is a controlled fatty-amide slip-agent dispersion on a polyolefin carrier that migrates to the film surface and reduces coefficient of friction for clean winding, smooth feeding and easy bag opening on packaging lines.
A fatty-amide slip masterbatch available in a slow-blooming grade (food-contact preferred) or a fast-blooming grade (immediate effect), pre-dispersed in a polyolefin carrier. The slip additive migrates to the polymer surface and lubricates every film-to-film and film-to-metal contact point on the line, dropping the kinetic coefficient of friction measurably. Used wherever a film must release cleanly from chill rolls, glide through FFS jaws or open without stick at the bag mouth.

Frequently asked questions
What’s the recommended letdown ratio in blown film?
Letdown ratio depends on film type, gauge and target COF. Thin liner film requires less than thicker industrial bags and FFS film. For multilayer barrier film where slip must not interfere with sealing layers, the formulation uses a slow-bloom grade to keep slip on the outer skin. Contact us for grade-specific guidance.
Which films and resins is it compatible with?
The polyolefin carrier is compatible with HDPE, LDPE, LLDPE, PP, BOPP and EVA. Slow-bloom grades are universal across PE and PP. Fast-bloom grades are preferred for LDPE film where quick bloom is needed. For high-temperature applications and EVA layers, grades with higher thermal stability are supplied.
How does it work mechanically?
Fatty primary amides are partially soluble in the polymer melt but exceed solubility at room temperature. After cooling, the amide blooms slowly to the surface and forms a microscopic boundary lubricant layer at the film surface. The hydrocarbon tail lies flat against the film; the polar amide head pairs with the next film surface, dropping film-to-film kinetic COF measurably from the untreated polyolefin baseline.
Slow-bloom or fast-bloom, which should I use?
The slow-bloom grade delivers durable slip for the full service life of the part with very low evaporation losses on storage. The fast-bloom grade gives an immediate effect but evaporates faster and is less suited to high-temperature handling. Use the slow-bloom grade for long-storage rolls and high-temperature handling, and the fast-bloom grade for immediate-use FFS lines.
Can I get a trial sample?
Yes. We supply 1-2 kg trial samples for line evaluation. Share film type, gauge, target COF, Anti-Block co-additive and any printing or lamination requirements; we ship a matched grade with a Certificate of Analysis. Sample shipping is free within India; export samples available with freight at cost.
What’s the lead time?
Standard grades ship in 7-14 working days. Combined slip+Anti-Block formulations or food-contact-certified grades take 3-4 weeks including documentation. We confirm an exact timeline at the quote stage.
