Product Description
Clearflex® FF508 is an octene copolymer linear medium density polyethylene (C8-LMDPE), with antioxidants and processing aid, suitable for blown film extrusion.

Film manufactured with Clearflex® FF508 are characterised by excellent optical properties, if compared to the resin density, high rigidity and temperature resistance, optimum sealing properties.

Due to its high optical, mechanical and sealing performances, Clearflex® FF508 is recommended for applications in which the high rigidity and the optimum gloss of this resin are a key factor (hygienic film, packaging for mineral water). The high Vicat softening point makes Clearflex® FF 508 ideal for the production of film for food which is submitted to pasteurisation or sterilisation process.
