Ko te arai putunga waro HDPE ārai mura he whakarāpopototanga o te papa polyethylene taumaha ngota teitei. Ko te pepa i ahu mai i ngā rauemi mata polyethylene taumaha ngota teitei, ā, ka tāpirihia ngā rauemi whakarerekē e tika ana kia rite ki ngā hiahia o te kiritaki, ā, ka whakaranua - te calendering - te sintering - te whakamatao - te tautuhinga pēhanga teitei - te tangohanga - te hanga. He pai te ātete kakahu, te tiaki taiao, te ārai-pūmau, te urunga, te ātete kakahu teitei, te ātete makuku, te ātete waikura, te ngāwari ki te tukatuka, te mimiti ru, te kore haruru, te ōhanga, te kore e huri, te ātete pānga, te whakahinuhinu-ake, ā, he whānuitia ngā tono. He pai mō te hanga i ngā momo wāhanga miihini katoa e ātete ana ki te kakahu.
He maha ngā āhuatanga pai o tēnei hua, pērā i te mama, te ātete ki te pānga, te ātete ki te kakahu, te ātete ki te waikura, te iti o te tauwehenga waku, te mimiti pūngao, te ātete ki te koroheketanga, te ātete ki te mura, te ārai i te pao, me ērā atu mea. Hei whakatairanga ake i te māramatanga o ngā kaiwhakamahi mō tēnei mea, me aro nui ngā kaimahi ngaio me ngā kaimahi hangarau ki te whakamahinga o ngā rau polyethylene penei:
1. Ina whakamahia tuatahitia, ka tukuna atu e mātou te rauemi i muri i te rongoa o te rauemi silo ki te rua-hautoru o te kaha katoa o te silo.
2. I te wā e whakahaerehia ana, me pupuri tonu ngā rauemi i roto i te whare putunga i te wāhi whakauru me te wāhi tango rauemi, ā, me pupuri tonu te rokiroki rauemi i roto i te whare putunga kia neke atu i te haurua o te kaha katoa o te whare putunga.
3. Kāore rawa e whakaaetia kia pā tika te pepa polyethylene ki te arai.
4. He rerekē ngā matūriki pakeke o ngā rauemi rerekē. Kaua te rauemi me te tere rere e whakarerekētia i runga i te hiahia. Ki te hiahiatia, kaua e neke atu i te 12% o te kaha hoahoa taketake. Mā te whakarerekē i te rauemi, i te tere rere rānei i runga i te hiahia ka pā ki te roa o te ora o te arai.
5. Kaua te pāmahana o te taiao e neke ake i te 80 ℃. Kaua e whakamahia te kaha o waho hei whakangaro i tōna hanganga, kaua hoki e wetekina ngā here i te wā e hiahiatia ana.
