Breathable Masterbatch for +Microporous Film Applications
Breathable Masterbatch
High-Performance Breathable Masterbatch for Hygienic & Industrial Film Applications

In today’s flexible packaging and hygiene industry, demand is rapidly growing for breathable films that allow moisture vapor to escape while still maintaining protection against liquids. Our Breathable Masterbatch is specially engineered to help manufacturers produce microporous breathable films with excellent permeability, softness, and mechanical strength.Our breathable masterbatch is widely used in diaper back sheets, sanitary napkin films, medical packaging, protective clothing, and agricultural mulch films, where controlled breathability is critical.We offer a technically optimized and consistent breathable masterbatch solution that ensures stable processing, uniform pore formation, and superior film performance, even at high production speeds
Breathable Masterbatch Additive
Water vapor transmission
Breathable Masterbatch is a functional additive concentrate designed to create microporous structures inside plastic films. When processed through film extrusion and stretching, it forms microvoids (tiny pores) that allow water vapor transmission (WVTR) while preventing liquid penetration.
Breathable masterbatch is primarily based on high-loading calcium carbonate (CaCO₃) combined with dispersion aids and processing stabilizers, enabling the formation of breathable film structures without compromising the film’s strength and quality.

How Breathable Film Works
(Microporous Technology)
The working mechanism of breathable masterbatch is based on micro-porous film formation technology.
During blown film or cast film extrusion:
The breathable masterbatch introduces fine CaCO₃ particles into the polymer matrix.
During stretching (MDO or film orientation), the polymer separates slightly around these particles.
This separation forms microvoids and channels, allowing vapor permeability.
The pore size is controlled to ensure high WVTR without compromising liquid barrier.
This process is known as “cavitation effect” and is the core principle behind breathable film manufacturing.

Breathable Masterbatch Composition (Technical Formulation)
Our breathable masterbatch is formulated with:
Ultra-fine coated CaCO₃ (Calcium Carbonate)
high purity, controlled particle size distribution
Polyolefin carrier resin (LLDPE / LDPE / PP)
compatible with most film-grade polymers
Special dispersion additives
ensures uniform filler dispersion & prevents agglomeration
Processing stabilizers & lubricants
improves extrusion stability and reduces die build-up
Anti-block & slip balancing additives
(optional) – for better handling and winding
We ensure that our breathable masterbatch provides consistent filler distribution, enabling stable pore development and excellent film uniformity.

Key Features of Our Breathable Masterbatch
High CaCO₃ Loading (Optimized for Breathability)
Our masterbatch contains high loading of coated CaCO₃, enabling strong pore formation and high WVTR values.
Excellent Dispersion in Polymer Matrix
Uniform dispersion prevents white spots, gel formation, or weak film zones.
Stable Processing & High Output
Designed for high-speed film lines, reducing pressure fluctuations and improving extrusion consistency.
Controlled Particle Size Distribution
Ensures predictable pore structure and stable breathable performance.
Low Die Build-Up
Our formulation minimizes residue and prevents frequent cleaning shutdowns.
Improved Film Softness
Breathable films become softer and more fabric-like, especially required in hygiene products.
Compatibility with LLDPE, LDPE & PP
Suitable for mono-layer and multi-layer film structures.

Key Benefits

Superior Moisture Vapor Transmission (High WVTR)
Our breathable masterbatch enables high WVTR films, improving comfort in diapers, sanitary napkins, and medical products.

Better Comfort & Breathability in Hygiene Products
Breathable films reduce sweating and skin irritation by allowing moisture vapor release.

Improved Film Printability & Surface Quality
Our breathable grades maintain good surface uniformity for printing and lamination processes.

Cost Optimization
High filler loading reduces polymer consumption and improves cost efficiency without sacrificing performance.

Consistent Quality Batch to Batch
We ensure strict QC controls, ensuring consistent results for large-volume buyers and OEM manufacturers.

High Production Efficiency
Smooth processing reduces downtime, improves winding quality, and enhances overall plant productivity.

Our breathable masterbatch is widely used across multiple industries.
