At Pigmatix, quality is an exact science. From prime virgin LLDPE resin verification to spectral colorimetry and blown film bubble tests, we enforce uncompromising standards on every production run.
A rigorous, systematic multi-gate QA process covering raw feedstock ingress through to automated packaging and lot release.
Every shipment of virgin LLD/LLDPE resin pellets is sampled for Melt Flow Index (ASTM D1238), pellet density, and moisture content before being cleared into production silos.
Loss-in-weight feeders continuously meter pigment concentrates and base resin with ±0.2% precision, preventing feed fluctuations and color drift during compounding.
High-shear co-rotating extruders disperse pigment agglomerates into primary particles while maintaining gentle melt temperatures to avoid thermal polymer degradation.
Lab technicians test extruded masterbatch samples for spectral color match (ΔE < 0.5), ash content (ASTM D5630), filter pressure value, and blown film sample clarity.
Upon passing all testing criteria, the batch is released with an official Certificate of Analysis (COA). Physical retain samples are cataloged and archived for 24 months.
Our on-site polymer testing laboratory is equipped with state-of-the-art diagnostic equipment to verify physical, thermal, and optical properties before any lot departs our plant.
Pigmatix operates within globally recognized polymer manufacturing and environmental quality frameworks.
Our quality control operations adhere strictly to ISO 9001:2015 principles of standardized documentation, continuous process improvement, and rigorous corrective action tracking.
Standard white, color, and additive grades are formulated using non-toxic raw materials compliant with FDA 21 CFR 177.1520 guidelines for direct food contact flexible packaging.
All organic and inorganic pigments are screened to ensure zero presence of restricted heavy metals (lead, cadmium, hexavalent chromium, mercury) or hazardous phthalates.
