Полипропилен R 450 F
Рандом сополимер. Для производства пленок методом литья под давлением и методм выдувки с охлаждением водой.

TIPPLEN R 451 F is a random copolymer polypropylene for the extrusion of cast and water-quenched blown film. TIPPLEN R 450 F is formulated with non migrative additive package containing antiblock agent. The product shows excellent transparency and very good heat weldability. The seal initiation temperature is about 130 °C. Typical application include the quality packaging either as monolayer film or as welding layer in coextruded structures. Film produced with TIPPLEN R 450 F is well suited for the packaging of foodstuff such as biscuits, sweets, pasta, tea and for the packaging of stationary, shirt etc. Because of the excellent heat weldability, TIPPLEN R 450 F is well suited for lamination of PP film or other materials such as PA, polyester or aluminium to form the sealing layer. TIPPLEN R 450 F especially usable for metallisation. TIPPLEN R 450 F is suitable for food contact. The product complies with FDA, BGA and EU norms.
