Exceptional transparency retention in polypropylene (PP) and polyethylene (PE) matrices without haze development.
High pigment dispersion stability ensures uniform coloration and minimizes filter pressure buildup during extrusion.
Carrier resin fully compatible with polyolefin processing temperatures (180–260 °C), enabling smooth melt flow and low die buildup.
Non-migrating formulation prevents blooming or staining on finished parts, maintaining long-term clarity and aesthetics.
Free of heavy metals and compliant with FDA 21 CFR §178.3297 and EU Directive 2002/72/EC for food-contact applications.
Transparent food packaging films and laminates (e.g., snack bags, bakery wrap).
Clear medical packaging trays and sterilization pouches requiring optical clarity and regulatory compliance.
Injection-molded transparent containers for cosmetics, household products, and pharmaceuticals.
Blow-molded bottles and jars where color consistency and light transmission are critical.
Thermoformed clear clamshells and display packaging for retail and e-commerce.

Q1: What types of polyolefin resins is this masterbatch compatible with?
A: This transparent polyolefin masterbatch is specifically formulated for use with homopolymer and copolymer grades of polypropylene (PP) and polyethylene (PE), including LDPE, LLDPE, and HDPE. It maintains optical clarity and dispersion stability in both melt-compounded and injection-molded applications.
Q2: How does this masterbatch preserve transparency in final parts?
A: The pigment system uses finely dispersed, high-purity organic pigments with refractive indices closely matched to those of common polyolefins. Combined with a low-viscosity, non-crystallizing carrier resin, it minimizes light scattering and phase separation during processing—enabling excellent clarity and gloss retention even at functional loadings.
Q3: What is the typical dosage range for achieving target color strength without compromising clarity?
A: Dosage depends on the desired shade intensity and base resin properties, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight. Lower additions are often sufficient for pastel or light tints, while deeper shades may require careful optimization to avoid haze onset.
Q4: Is this masterbatch suitable for food-contact or medical-grade applications?
A: The masterbatch can be supplied in compliance-ready formulations using FDA-listed and/or EU-permitted pigments and carrier resins. However, final regulatory suitability depends on the complete formulation, processing conditions, and end-use requirements—so validation testing under actual application conditions is strongly recommended.
Q5: Does this masterbatch require drying before processing?
A: While the carrier resin is inherently low-moisture, standard handling practices for polyolefin masterbatches apply. For optimal dispersion and clarity—especially in high-precision or thin-wall applications—we recommend drying at 60–70 °C for 2–4 hours prior to processing, particularly if exposed to ambient humidity for extended periods.
