S 38 FA

S 38 FA

S 38 FA is a homopolymer designed for the manufacturing of coextruded biaxiafly oriented polypropylene films. The product is used for the core of the coextruded film structure with a low seal temperature random copolymer in the outside layers.
S 38 FA has been designed to provide a very stable extrusion on stenter lines and to give excellent thickness control, increased drawability and readiness to a two way orientation.
The product contains a reinforced processing stabilisation and a package of slip and antistatic agents but does not contain any antiblocking agents.
BOPP films produced with S 38 FA feature good mechanical properties, high impact strength and puncture resistance, even at low temperatures.
The films form an excellent barrier against moisture, odours, oils, fats and oxidation and feature high transparency, high gloss and good printability after corona treatment.
The low sealing biaxially oriented coextruded films obtained with S 38 FA can be used for Vertical Form Fill Seal applications and lamination as well as Horizontal Form Fill Seal and overwrapping applications, according to the thickness and sealing properties obtained.
Coextruded film with a thickness of 20 to 40 μm is used for the automatic packaging of bakery products, snacks and pasta as well as for the overwrapping of boxes and cigarette packets.
