PIB MASTERBATCH

Product Description:

Polyisobutylene Additive (PIB Masterbatch) is a based on a special blend of Polyisobutylene with base polyethylene, elastomeric olefins and active additives. The composition is used as a adhesion promoter (cling agent) to produce stretch wrap films from LLDPE or LDPE, the high molecular weight Polyisobutylene content in the base polyethylene and matrix achieves the excellent stickiness property in the dry granules, it is dry free flow granules

Polyisobutylene Additive (PIB Masterbatch) is available in the granule form which is very easy to handle as against the direct dosing of Polyisobutylene liquid which is very difficult & tedious to handle due to high viscosity. Our Polyisobutylene Additive 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 wrap the packages together with proper grip.

Polyisobutylene Additive (PIB Masterbatch) is designed to produce stretch wrap films from LLDPE, LDPE or any other Nonslip Polyolefin’s for the applications of Pallet wrap and Silage wrap. It can be used on either blown film line or cast film process. Polymers used with Polyisobutylene Additive must not contain any Anti blocking additive or slip agent as this will prevent the migration of cling additive on the films. Migration time for the good cling properties is usually 24 to 72 hours.

Machine Stretch Film

Stretch Silage Film

Color Stretch Film

Pre Stretch Film

We suggest the following addition level :

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

Blown Film Line:

è PIB Additive, use in monolayer blown film line approx 5 to 7% should be added to with resin mix

è PIB Additive, use in multilayer blown film lines are usually added to the skin layers only. Addition level

     Of depends on which layer is used and the thickness of layer, it can be use approx 3 to 5%

Cast Film Line:

è PIB Additive, use in monolayer cast film line approx 2 to 4% should be added to with resin.

  

è PIB Additive, use in multilayer cast film lines are usually added to the skin layers only. Addition level

     Of depends on which layer is used and the thickness of layer, it can be use approx 1 to 2%

Note: 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.

Blown Films Application : 03 to 07%

Cast Film Application : 01 to 02%
