  • By bottom gusset colors method

This method is applied to the U-style spout pouch

1-Bottom gusset color is dark silver,that means the pouch made by PET/AL/Nylon/LLDPE or PET/AL/Nylon/RCPP;

2-Bottom gusset color is bright silver,that means the pouch made by PET/metalized-PET/LLDPE;

  • By destructive method

This method is applied to the W-bottom style pouches with spouts,because this kind of spout pouch is made by the special pouch making machine,we can not distinguish the pouch material structure through the bottom gusset color,the only way is destroy the pouch (directly shear the pouch body).
