Extrusion International 6-2023

24 Extrusion International 6/2023 INDUSTRY NEWS Capacity, Portfolio and Service in Polycarbonate Additives Boosted Tosaf strengthens its commitment around additives for polycarbon- ate (PC), which are mainly used for the extrusion of transparent sheets, profiles and films. This includes the development of new, market-driv- en specialties as well as the devel- opment of new markets worldwide. A recently commissioned cutting- edge compounding line at the Alon-Tavor site in Israel increases the company's flexibility in meeting customer requirements, while at the same time shortening delivery times and expanding options for produc- ing sophisticated masterbatches. Tosaf's new developments include light diffuser masterbatches for PC and PMMA. Thanks to a high load- ing level, low dosing quantities are sufficient, enabling particularly eco - nomical solutions. On top of that, they offer a good compromise be- tween high hiding power and high light transmission. Other innova- tions are heat blockers for the near IR range (NIR blockers) and additives for creating matt surfaces with ei- ther a fine or rough structure. Both of the latter are intended to be ap- plied to the surface of PC sheets by coextrusion, each in combination with a UV absorber. As a 50 µm to 100 µm thick top layer, they work much more efficiently there than when added directly to the sheet bulk. Beyond, Tosaf also offers two types of anti-block that are tailored to prevent corrugated sheets from sticking together, again providing high efficiency even in small doses. In addition to the aforemen- tioned products for UV stabilisa- tion as well as for achieving matt surfaces, near-IR blockers and anti- block additives, Tosaf's portfolio of compounds and masterbatches for PC also includes flame retardants, glass fibres and a wide range of color masterbatches. To meet the strictest quality re- quirements, Tosaf produces its en- tire portfolio of polycarbonate compounds for global demand ex- clusively in its Alon-Tavor additives factory, which is state-of-the-art re- garding the production and quality assurance of these sensitive prod- ucts. All new and further develop- ments are also carried out in Tosaf's development centre at the same location, which makes the scale-up to production conditions much saf- er and easier. Only the production of color masterbatches for PC takes place in a dedicated color com- pounding site, which is also located in Israel. Local supply to PC sheet manufacturers is handled by sales offices in Europe, South America, North America, Turkey, Asia, China and India, the Persian Gulf and the Israeli market.

Collaboration to Create New Mono-Material Packaging Mondi has collaborated with Skånemejerier to cre- ate a mono-material, polypropylene (PP) based pack- aging for, among others, ICA’s Hushållsost cheese. The new packaging comprises a mono-material base web and lidding film, all of which is produced and printed by Mondi before being converted for 1kg and 2kg blocks of cheese by Skånemejerier. It will be sold in leading Swedish supermarket ICA and now comes in packaging that is designed for recy- cling. Say cheese!
