High ability of tensile and tear property, quite stiffer but not flexible like PE, unable to be stretched for long, so it was made into yarn. Especially, less ability of tear property when there is a cut or a small puncture wound.
– Transparent with gloss surface. Apply for printing industry with clear definition.
– Ability of heat pressure over 100o C. In comparison with PE – it can damage to exterior laminated structure, so it is rarely used as inner layer.
– Creating a greater degree of crystallinity, making PP stiffer and more resistant to creep (the tendency to flow under stress) as compared to polyethylene (PE)…
– Almost completely impervious to water: O2, steam, grease and other gases.
