PET Masterbatch

A masterbatch is a specific kind of pellet (plastic chips) having a well established dosage of an active chemical ingredient or pigment and, in some cases, some particular additives. Actually, it can be described as a concentrated mixture of pigments and/or additives into a carrier resin.

Parmar Polymer have developed a range of innovative masterbatches for use in PET extrusion and injection stretch blow moulding. Recent improvements in engineering and product technology has yielded a number of options to find solutions for some of the most demanding packaging applications.

Masterbatch is usually mixed together with a plastic polymer in a feeder, just before the extrusion process. The advantage of a masterbatch, is to make the mixing and dosage process of all ingredients easier and to grant repetitiveness of performance.
