Precision-compounded polyethylene color carriers optimized for zero-migration blown film and injection molding.
In high-end polyolefin processing—ranging from multi-layer blown films for flexible packaging to agricultural geomembranes and food-contact containers—pigment migration (bleeding, blooming, and exudation) presents a critical failure mode. Migration occurs when organic pigment molecules or low-molecular-weight additives dissolve slightly in the polymer matrix, diffusing to the surface under thermal gradients or contact pressures.
As a leading China High Anti-Migration PE Masterbatch Supplier & Manufacturer, Changzhou Jiazhou Plastic Products Co., Ltd. resolves this structural issue. By utilizing narrow molecular weight distribution (MWD) Polyethylene carriers combined with high-purity inorganic structures and surface-passivated organic pigments, our masterbatches lock colorants firmly within the host resin matrix even under extreme processing temperatures up to 260°C.
Our anti-migration PE formulations achieve Grade 5 (no bleed/stain) under ISO 105-X12 testing and DIN 54002 grey scale evaluations across organic solvents, plasticizers, and fatty food stimulants.
Eliminates color transfer onto adjacent materials during long-term storage or contact wrapping.
FPV < 0.8 bar/g guarantees exceptional dispersion and prevents screen pack clogging during high-speed film blowing.
Maintains structural and chromatic integrity across intense shear stress and elevated extrusion heat.
Fully compliant with FDA 21 CFR 177.1520, EU No 10/2011, RoHS 2.0, and REACH SVHC requirements.
Tested and verified by Changzhou Jiazhou R&D Quality Control Laboratories under standardized ISO/ASTM protocols.
