S 28 C
S 28 C is a modiﬁed homopolymer designed for the very high speed production of BOPP ﬁlms.S 28 C allows an outstanding extrusion stability and thickness variation control and provides a very high drawability and readiness to a two way orientation. The product contains a reinforced processing stabilisation and features low water carry-over properties.
BOPP ﬁlms produced with S 28 C feature good mechanical properties, high impact strength and puncture resistance, even at low temperatures. The ﬁlms form an excellent barrier agains moisture, odours, oils, fats and oxidation and feature good transparency and gloss.
Monolayer or coextruded ﬁlms made of S 28 C with a thickness ranging from 20 to μm are used for the packaging of foodstuffs, cosmetics and videocassettes.
