Masterbatch for PP, PE and PET packaging reduces friction, eases mold release

The new masterbatch, dubbed Denestur, is made and marketed by plastics masterbatch supplier Ampacet (Tarrytown, NY). The masterbatch can be used in plastics packaging made from polyethylene terephthalate (PET), polyethylene (PE) and polypropylene (PP). According to Ampacet, this masterbatch imparts an easy-glide, anti-static, no-stick characteristic, eliminating build-up from the mold and machine surfaces.
 
The result is friction reduction of up to 70% for PET, PE and PP; from 25% to 50% lower force required for mold release and de-nesting; a reduction in scratch depth of up to 50%, and improvement of 10-25% in packing density. Combined, these improvements can lead to less machinery jamming, equipment damage, and material waste.

The Denestur masterbatch formulations can be used with a white and black masterbatch and custom color formulations. It can also be used as a stand-alone additive for use with polypropylene (product 40604), polyethylene (product 10090) and PET (product 703853).  As expected form a product introduced for food packaging, it is FDA compliant, with no effect on color, clarity or resin properties.
