White Masterbatch for Films, TiO₂ 25%
Description
White masterbatch (white concentrate) based on rutile TiO₂ — 25% active pigment with 43% CaCO₃ as a co-active filler in a polyethylene carrier matrix. Designed for the production of packaging, agricultural and technical films by blown or cast (flat-die) extrusion, where stable opacity, rich whiteness and good dispersion without defects ("fish eyes") are required. Economy grade: 25% TiO₂ + 43% CaCO₃ provides the optimum price/opacity balance for high-volume packaging solutions.
Key properties
- TiO₂ concentration 25% + CaCO₃ 43% in a PE carrier
- High opacity at a dosage of 3-8% of film weight
- Good dispersion — no "fish eyes" on thin films of 20-100 µm
- Compatible with LDPE, LLDPE, HDPE, PP — standard blown/cast lines
- Economy grade — optimum opacity/price ratio
- UV stabilization with an additional UV-MB if required (for agricultural films)
Applications
Packaging films. Polyethylene packaging for food and non-food products (sacks, bags, shrink film). Compliance with 10/2011 (EU food contact for plastic packaging) — per individual batch specification.
Agricultural films. White mulch films, greenhouse films with minimal sunlight transmission, silage films.
Construction films. White films for waterproofing, vapor barriers and temporary covering.
Technical films. Stretch film, banding film, liner materials.
Injection molding. White parts for household appliances, molded packaging — economy grade.
Regulatory notes
TiO₂ as food additive E171 has been banned in the EU since 7 August 2022 (Regulation (EU) 2022/63, based on the 2021 EFSA opinion that a safe daily intake could not be established due to nanoparticle accumulation). This restriction applies to food products, not to packaging films. The use of TiO₂ as a pigment in plastic packaging remains permitted under Regulation (EU) 10/2011, subject to the Specific Migration Limit (SML) for food contact. For food-contact applications, request a Declaration of Compliance (DoC) for the specific product and contact conditions.
