Additive for Film

Advanced Specialty Polymer

Functions

  • It is used as an additive to add an anti-blocking and slip effect to various polyolefin film (BOPP, CPP) by using the low coefficient of friction due to the beads shape and even particle-size distribution.
  • It recreates the stable quality and excellent function compared to an existing inorganic material or other competitor products by using the functional packaging film (BOPP, CPP) used for snacks such as instant noodles, etc.
  • It is coated on various films to give matting and anti reflection effects.
  • In addition, it is added to plastic directly to give texture and matting effects on the surface by creating a unique design and texture.

Anti-blocking for Packaging film(BOPP and CPP)

  • Very spherical polymer bead lower the static and dynamic friction value.
  • Compared with competitor’s PMMA and Silica, we have very narrow particle size distribution and spherical shape that leads very smooth protrusion and lower friction value.

Silica

Static friction 0.50us

Dynamic fiction 0.35us

MH-5FHD

Static friction 0.39us

Dynamic friction 0.30us

Anti-blocking for film

  • Various size and materials can be supplied for the customer’s requirement.
  • All of the product show the more enhanced friction coefficient.

Anti-glare coating for film

  • We have several types of polymer beads with different refractive index.
  • Also, several size polymer beads can be used for Anti-glare effects.
