Anti Block Cum Slip Masterbatches

 Slip additive Masterbatches are added to films reduce the coefficient of friction while maintaining transparency and gloss. Different slip additives are added to films based on film construction processing conditions. Printability at various stages needs to be considered seriously in selecting the best anti block masterbatch. They are used to minimise the adhesion on similar parts of converting equipment & allow easy sliding over. Slip additives also allow easy mould/die release, but extra additions make issues like die deposition & printability issues at later stages.

Antiblock additives reduces the adhesion between layers by creating microrough surfaces. Many types of antiblock additives are available, ranging from synthetic silica which give high clarity, to natural silica or Talc where cost is important and clarity can be compromised to calcium carbonate where simple antiblocking without clarity is required. In many cases, these are used in masterbatches for multilayer film structures where both performance and processability matter.

Anti Block Cum Slip Masterbatches can be produced in a wide range of polymers like polyethylene, polypropylene, polyamides, Acrylic polymers, Polyesters etc. For speciality applications organic base antiblocks are used.

 Combinations of antiblock and slip products offer cost-effective products for use in the films. A combo anti block masterbatch containing both additives is used for ease of mixing.
