PP woven bags are widely used in packaging, agriculture and logistics for durability, low cost and recyclability. White masterbatch, a concentrated mix of titanium dioxide, carriers and additives, integrates with PP resins to boost bag appearance, performance and functionality. This article introduces key types, technical specs and tips for choosing a reliable PP masterbatch supplier.
Specialized formulations cater to different application needs. Below are the three most common types:
PP white filler masterbatch balances cost and basic performance, containing 15%-25% titanium dioxide, PP carriers and dispersants. Inorganic fillers cut raw material costs while enhancing bag rigidity and printability. Suitable for indoor packaging (grain, fertilizer sacks), it meets ≥85% whiteness and ≤0.1% moisture content to avoid processing flaws.
Anti-UV white masterbatch is essential for outdoor PP woven bags (construction materials, agricultural covers). It adds 0.5%-1.0% UV absorbers or HALS, blocking over 95% of UV rays (≤380nm). This extends outdoor service life from 3-6 months to 1-3 years, preventing brittleness and discoloration, complying with HG/T 4668-2014 Grade W.
Eco-friendly white masterbatch gains traction amid strict environmental rules. It uses food-grade titanium dioxide and recyclable PP carriers, free from heavy metals (≤1ppm) and phthalates. Certified by EU RoHS, REACH and FDA 21 CFR, it suits food/medical packaging with ≤10mg/dm² total migration, supporting PP bag recycling.
Typical parameters of high-quality white masterbatch (per industry standards):
A quality PP masterbatch supplier ensures stable production. Focus on three factors: technical strength (advanced lines, R&D teams and testing tools), product quality (third-party reports from SGS/OEKO-TEX 100) and after-sales service (4-hour technical support and custom formulations).
In summary, white masterbatch tailors PP woven bags to diverse needs. Understanding specs and choosing a trusted PP masterbatch supplier enhances product competitiveness while meeting environmental and performance demands.
