pigments can replace a portion (typically 10-20%) of the TiO2
in a formulation. The company’s latest
version, FP-545, is based on a particle treated with stearic acid, rather than the trimethylol propane organic surface treatment used in the FP-540 grade that was introduced in 2021 along with the untreat- ed FP-440 grade. The FP-440/540/545 series uses less TiO2
than
the company’s earlier versions, to produce a similar optical effect with less expense and lower carbon footprint.
“Our control of the calcium carbonate precipita-
tion process has allowed us to entrap some additional air in the particle, thereby increasing the effective light scatter in a modified way and subsequently allowing for the formulation of an FP-Pigment particle containing even less TiO2
but
delivering similar optics,” said Andy White, Business Unit Director Paints and Plastics at FP-Pigments.
Food packaging FP-440, with no extra organic coating, is designed for compounds. FP-540 and FP-545 are designed high pigment-concentration masterbatches, where the extra surface treatment is needed to aid dispersion, White explained. The masterbatches can be used in food packaging. Tosaf, a supplier of white and additive master-
batches, recently announced that its production facilities have achieved ISO certification regarding food safety, in addition to previously obtained ISO quality certifications. “Tosaf places great importance on supplying the food industry with high-quality raw materials that meet the strictest requirements,” said Dina Khom-
chuk, Q&A Manager for Tosaf’s Additives Business Unit. “As part of the new ISO 22000 certification including ISO 22002 Part 4, which is specifically tailored to food packaging, we have comprehen- sively adapted our processes to this area of application and optimised them even further. We have developed a multi-year plan that includes measurable goals in the areas of quality, food safety, and environmental quality. We allocate resources and train the entire organisation in food safety. On this expanded basis, Tosaf is looking forward to growing in the market for masterbatches for food packaging.” The company says its white masterbatches withstand demanding processing conditions and offer high dispersion quality and colour strength. They can be designed for specific application requirements as well, such as organoleptic properties for milk packaging.
