PIB MASTERBATCH  PT-60  FREE FLOW 

INTRODUCTION

‘Polyfill’ PT-60-PIB Masterbatch is a average molecular Poly Isobutylene based Masterbatch based on Polyolefins, used in LLDPE / LDPE self adhesive Stretch Film, Cling Film, & Wrap Film (either Blown Film or Cast Film) and it is available in-granule-form.

PIB master batch PT60 is very easy to handle as against the direct dosing of PIB liquid which is very difficult & tedious to handle due to high viscosity. Our PIB master batch distributes very uniformly over the entire film imparting the strength & tackiness properties to the film with self adhesive properties. And this property of the film helps to bind the packages together with proper grip. In multi-layer films, PIB master batch ,is used only in one layer , the upper layer and the adding ratio is determined by the film thickness and on the layer to be used.

ADDITION-LEVELS

Cling films made from our PIB master batch are most economical and the quality of the film coverage increases on stretching. The loading of PIB master batch varies from 1% to 5% depending upon the type of the film plant (Blown or Cast-Line)--installed.

We suggest the following addition level based on the test results from outdoor weathering tests and from practical experience :
BlownFilm—Application  3----5%

CastFilm—Application 1----2%
The above dosages are for guidance only. Actual condition may vary from film to film, process to process and also upon the thickness of the film and its specific-uses.

MATERIAL--MIXING

To get the best results in case of extrusion, it is advisable to mix the material thoroughly before feeding in a hopper.
