Description
Medical-Grade Transparent Filler Masterbatch
Medical-grade transparent filler masterbatch (formulated with ultra-pure precipitation BaSO4 and premium virgin polyolefin carrier) is specifically engineered for medical and pharmaceutical flexible packaging applications, including blood bags, saline infusion bags, medical self-seal sterilization pouches, and pill/prescription pouches.
Key Features:
-
Ultra-High Purity & Chemical Inertness: Manufactured with certified high-purity inorganic micro-powders with exceptionally low heavy metal limits. Fully non-toxic, odorless, and chemically inert with zero leaching or migration into pharmaceutical solutions and blood components.
-
Exceptional Optical Clarity: Perfectly matched refractive index with medical-grade PE and PP resins, ensuring maximum film transparency and surface gloss for clear visibility of contents, dosage lines, and fluids.
-
Superior Cleanroom Extrusion: Ultrafine dispersion and advanced surface treatment prevent gel formation, fish eyes, or die-lip build-up, ensuring smooth processing in cleanroom blown film and cast extrusion lines.
-
Sterilization Resistance: Excellent thermal and irradiation stability, maintaining mechanical strength and optical properties through autoclave steam sterilization, ethylene oxide (EtO), and gamma-ray irradiation without yellowing or embrittlement.
-
Hermetic Heat-Seal Integrity & Toughness: Enhances the film’s tensile strength and puncture resistance while ensuring reliable, leak-proof high-frequency and thermal sealing under pressure.
-
Cost Efficiency: Optimizes production economics by replacing prime medical resin without sacrificing strict pharmacopoeia and biocompatibility standards.
