Producing a reliable Functional Masterbatch begins long before the twin-screw melts the first pellet. In our facility, every batch follows a roadmap that integrates material science, process control, and traceability—without ever relying on flashy claims.
Raw-material triage
Carrier resin arrives with certificates confirming melt-flow index, ash content, and moisture levels. Additives—antioxidants, UV stabilisers, antimicrobial agents—are sampled by FTIR to verify purity. Any deviation triggers quarantine and supplier feedback before production starts.
Dosing and dispersion
Functional Masterbatch demands exact ratios. Gravimetric feeders meter additives to ±0.1 % accuracy, while twin-screw kneading blocks are configured for gentle shear. This prevents platelet fracture in barrier additives or agglomeration in antistatic systems. Inline torque monitoring flags viscosity spikes before they affect colour or performance.
Quality gates
Every 30 minutes, a technician pulls a strand sample. Melt index, ash content, and additive concentration are logged against a digital batch sheet. Spectrophotometer readings ensure colour consistency for pigmented grades, while surface-resistivity meters verify antistatic levels in real time.
Regulatory alignment
Food-contact masterbatches undergo migration tests in 95 % ethanol and 3 % acetic acid at 40 °C for ten days. Heavy-metal screens meet RoHS and REACH limits, and certificates are uploaded to a cloud portal accessible to customers 24/7.
Packaging and logistics
Concentrates are pelletised, cooled, and vacuum-sealed in foil-lined bags with desiccant. Barcodes link each bag to the original batch record, enabling full traceability from moulding machine to end consumer.
By integrating tight dosing, inline analytics, and regulatory documentation, the plant delivers Functional Masterbatch that meets both performance targets and global compliance—quietly supporting everything from juice bottles to hospital tubing.
