Polypropylen (PP)

The standard variation, Ho-PP (homopolymer) is stiffer/more transparent and is produced from polypropylene. Through enrichment with PE, the Co-PP becomes softer and milky. The highly transparent types are based on isotactic PP. PP exhibits good steam blockage, but insulates poorly against gas. The chemical resistance to oil/grease is good. Often employed for MAP-packing as a multi-layered foil like PP-EVOH-PP and as an EPP, i.e. XPP foamed variant. Ho-PP can be employed in a temperature range of 0 ° C to +120° C. Co-PP can be employed in a temperature range of -40° C to +120° C.
