PIB MASTERBATCH – PT**0 FREE
FLOW
PT***-PIB 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 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 3% to 8% 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 :
Blown Film
Application : 5 to
8 %
Cast Film Application
: 2 to 4 %
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.
