S 28 C

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.
