This is mostly suitable to the plastics goods manufacturing industry. The boon available to plastic processing industry is that there is a possibility to use recycled plastic products and use these in as much proportion as possible with virgin material.

We have expert team of packers, who know the art of packing. We have special transport vehicle for safe and fast transport services in all over India. We provide cheap and best home goods moving services

Antistatic masterbatch plastics are having high surface and volume resistivity which make them good electrical insulators. But because of it, they have tendency to accumulate electronic charge (static electricity) produced during high speed processing and subsequent use.

This is advantageous when the film is subsequently printed and sealed. Erucamide is also preferred in film which is to be laminated because of its low migrating tendency which can otherwise affect the bond strength. It is important that one should not overdose the slip masterbatch during processing as it may lead to screw slip, poor print adhesion, poor sealing and bond strength..

In pigmentary masterbatch, suitable organic or inorganic pigment is dispersed in a carrier resin to produce masterbatch of desired colour. In general, organic pigments have better tinctorial strength, higher brillance, lower opacity, lower toxicity, poor heat and light stability and poor migration resistance as compared to inorganic pigments. Hence, while selecting a pigment or combination of pigments for making a particular coloured masterbatch, following points are considered. Hue, value, chroma of the pigment. Heat and light stability required in the end product viz. organic pigments cannotwithstand higher processing temperature above 240°C. Resistance to migration and bleeding required. Dispersion of the pigment in carrier resin. Some of the pigments cannot be used in direct food contact applications due to their toxicity. Price of the pigment.Either a single pigment or combination of pigments are used to produce any desired colour.

These are the most widely used masterbatches for colouring of plastics especially plastics films. A white masterbatch contains very high concentration of Titanium Dioxide (TiO2) pigment in the carrier resin. Selection of proper grade of Tio2 forms a basis of any white masterbatch.
