PIB
Masterbatch
Engineered polyisobutylene solutions delivering unmatched cling, strength, and clarity for stretch, wrap, and packaging films.
Explore Applications →
Polyisobutylene,
Precisely Formulated
PIB masterbatches consist of a unique concentration of special-grade Polyisobutylene (PIB) with a high molecular weight, combined with LLDPE and elastomers — available as uniform, translucent granules ready for direct processing.
- ◆ High molecular weight PIB polymer matrix
- ◆ LLDPE (Linear Low-Density Polyethylene) carrier
- ◆ Elastomeric components for superior flexibility
Why It Matters
Why is PIB Masterbatch Needed?
Modern packaging demands performance that basic polymer films alone can't deliver. PIB masterbatch bridges this gap — transforming ordinary film into an intelligent packaging material.
Superior Cling Performance
Ordinary LLDPE films lack natural tack. PIB migrates to the film surface over time, creating a self-adhesive layer that clings firmly without external adhesives or coatings.
Oxygen Barrier Enhancement
Food products spoil faster when exposed to oxygen. PIB masterbatch significantly reduces oxygen permeability in stretch and cling films — extending shelf life and maintaining freshness.
Stretch & Load Retention
Pallet wrapping demands films that stretch without snapping and hold load tension over time. PIB adds elasticity and memory, preventing load loosening during transport and storage.
Processing Efficiency
Masterbatch delivery provides precise, consistent PIB concentration — eliminating the handling difficulties of neat PIB liquid and ensuring batch-to-batch reproducibility.
Compatibility Across Polymers
Compatible with LDPE, LLDPE & PP, PIB masterbatch integrates seamlessly into existing blown or cast film lines without equipment modifications.
Cost-Effective Functionality
Adding PIB via masterbatch eliminates the need for costly specialty films or secondary coatings — delivering premium properties at significantly lower total production cost.
Applications
Built for Every Film Format
From industrial pallet wrapping to delicate food preservation, PIB masterbatch enables superior performance across all major film applications.
Stretch Film
PIB masterbatch is the key ingredient in stretch film production — enabling the self-cling behavior essential for pallet wrapping, silage baling, and secure bundling applications.

Wrap Film
Whether produced via blown or cast film extrusion from LLDPE or LDPE, PIB masterbatch uniformly enhances adhesion, transparency, and mechanical properties of wrap films.

Unique Properties of PIB Masterbatch
Precision-engineered to deliver six critical performance dimensions that define high-quality packaging films.
Uniform Distribution
PIB masterbatch ensures perfectly uniform distribution of PIB throughout the film matrix — eliminating hot spots, streaks, and inconsistent cling behavior across the film web.
Strength & Tackiness
Delivers excellent tensile strength combined with superior tackiness and self-adhesive properties — balancing structural integrity with surface cling performance.
Balanced Peel & Lap Properties
Optimized formulation provides ideal attack force and controlled noise levels during unwind — meeting strict performance criteria for automated packaging equipment.
Oxygen Permeability Resistance
High molecular weight PIB polymer creates an effective barrier against oxygen transmission — maintaining product freshness and extending the shelf life of packaged goods.
Multi-Polymer Compatibility
Suitable for LDPE, LLDPE, PP and other polyolefins — offering universal applicability across blown film, cast film, and co-extrusion film production processes.
Translucent Appearance
Natural translucent granule form ensures no color interference with final film products — maintaining optical clarity critical for food packaging and display applications.
Key Benefits
Performance That Delivers Results
Every formulation decision in Bajaj PIB masterbatch translates to measurable benefits at the production line and in the field.
Improved Load Containment
Enhanced cling and stretch recovery properties ensure pallets remain firmly wrapped during shipping — reducing product damage and warehouse losses significantly.
Extended Food Shelf Life
Superior oxygen barrier performance in PIB-enhanced cling films keeps food fresher longer — reducing food waste and improving consumer satisfaction.
Processing Versatility
Compatible with standard blown and cast film equipment. No line modifications required — simply incorporate PIB masterbatch into your existing formulation.
Consistent Quality Output
Masterbatch format eliminates the handling, measuring, and blending variability of neat PIB — delivering consistent film properties across every production run.
Reduced Total Cost
Precise dosing efficiency and elimination of secondary treatments or coatings delivers significant cost savings compared to alternative film enhancement methods.
Optical Clarity Maintained
Translucent formulation preserves film transparency — critical for food display packaging where product visibility directly influences purchasing decisions.
Importance
Why PIB is Critical to Modern Packaging
The global stretch film and cling film industry depends on PIB to deliver the cling performance that end-users expect. Without PIB, standard LLDPE film would not adhere to itself or to goods — rendering pallet wrap functionally useless.
The Science Behind the Cling
PIB (Polyisobutylene) is a synthetic rubber characterized by extremely low gas permeability, excellent adhesion to smooth surfaces, and a natural migration behavior in polyolefin films.
When blended into LLDPE film at the masterbatch stage, PIB molecules gradually migrate to the film surface — creating a tacky layer that provides cling without compromising optical or mechanical properties.
This migration mechanism is time- and temperature-dependent, allowing film manufacturers to optimize cling development for their specific application — from immediate-use food wrap to extended-storage pallet films.
"PIB masterbatch is the enabling technology that makes modern stretch film packaging possible — it's not optional, it's foundational."

Manufacturing
How PIB Masterbatch is Made
Bajaj's precision manufacturing process ensures every batch delivers the exact PIB concentration and distribution needed for consistent film performance.
Raw Material Selection
High molecular weight PIB polymer is selected and quality-verified alongside LLDPE carrier and elastomeric components.
Precision Weighing & Dosing
Each component is weighed and dosed with laboratory precision to achieve the exact PIB concentration specification.
Compounding & Dispersion
Components are melt-compounded in high-shear twin-screw extruders, achieving homogeneous PIB dispersion throughout the carrier matrix.
Granulation & QC
Compound is pelletized into uniform granules, then subject to rigorous quality control — testing cling, optical, and mechanical properties before dispatch.
