Me aro nui ki te whiriwhiri i ngā rauemi mata me te tukanga hanga i te wā e hangaia ana ngā papa PE. Ko ngā rauemi mata mō te hanga pepa PE he rauemi mata ngota kore mahi, ā, he ngoikore te rere o ngā rauemi mata. Nā tēnei i puta ai he raruraru iti ki te hanga pepa PE, nō reira he mea tino nui te whiriwhiri i ngā rauemi mata mō te hanga pepa PE. Hei whakaoti i ngā raruraru o te uaua o te mate me te pikinga o ngā mea hau e hua mai ana i te ngoikore o te rere o ngā rauemi mata, me tāpiri ētahi hinu whakahinuhinu i te wā e whiriwhiri ana i ngā rauemi mata. Ko te nuinga o ngā hinu whakahinuhinu ko te waikawa stearic me ngā tote. Ko te pepa PE e hangaia ana i tēnei ara he rauemi ōrite, kāore he mirumiru hau.
Mō ngā tikanga hanga, ka taea te whiwhi panera PE kounga teitei ake mā te whakapai ake i te tukanga hanga. Ko ngā tikanga matua hei whakapai ake i te tukanga ko te hopu i te nui o te rauemi whāngai, te ine i te nui o te rauemi e hiahiatia ana i mua i te wā, kaua e whakakī rawa, kaua hoki e kore rawa ngā rauemi, me te whakatika i te nui o te rauemi ki te taumata teitei ake mō ngā papa PE. He pai ake te whakamahi i te tikanga werohanga tere me te pēhanga teitei hei whakaputa, kia pai ake ai te whiwhi pereti.
