I ngā tau tata nei, kua whānui haere te whakamahinga o ngā takai ngongo. I roto i te umanga whakapaipai, he tino pai ki te whakamahi i ngā takai ngongo whakapaipai mō te hanga-ake, te whakamahi i ia rā, te horoi me ngā hua tiaki, nā te mea he ngāwari te pēhi i te ngongo, he ngāwari ki te whakamahi, he māmā, he ngāwari hoki ki te kawe, ā, ka taea te whakarite kia rite ki ngā whakaritenga me te tā. Ko teNgongo PE(ngā ngongo hiato kirihou katoa) tētahi o ngā ngongo tino rongonui. Me titiro tātou ki te aha te ngongo PE.

Ngā momo PETube
E ai ki te hanganga o te tinana paipa: paipa paparanga kotahi, paipa paparanga rua, paipa hiato
E ai ki te tae o te tinana o te ngongo: ngongo mārama, ngongo mā, ngongo tae
E ai ki te rauemi o te tinana o te ngongo: ngongo ngohengohe, ngongo noa, ngongo mārō
E ai ki te āhua o te tinana o te ngongo: ngongo porowhita, ngongo papatahi, ngongo tapatoru
Rere Tukanga o te Ngongo PE

Ngā Painga me ngā Huakore o te Ngongo PE
Ngā Painga:
a. He pai mō te taiao.Ki te whakatauritea ki ngā ngongo hiato konumohe-kirihou, ka whakamahia e ngā ngongo hiato kirihou-katoa he rau kirihou-katoa he iti te utu, he ngāwari hoki ki te hangarua, ka taea ai te whakaiti i te parahanga taiao mai i ngā para tākai. Ka taea te whakaputa i ngā ngongo hiato kirihou-katoa hangarua i muri i te tukatuka anō ka taea te whakaputa hua iti te kounga.
b. Ngā tae kanorau.E ai ki ngā āhuatanga o ngā mea whakapaipai me ngā hiahia rerekē o ngā kaihoko, ka taea te hanga i ngā ngongo hiato kirihou katoa ki ngā tae rerekē, pērā i te kore tae me te mārama, te mārama tae, te kore tae, me ētahi atu, kia pai ai te tirohanga a ngā kaihoko. Ina koa, ka taea e ngā ngongo hiato kirihou katoa te kite mārama i te āhua tae o ngā ihirangi, ka hoatu he pānga tirohanga kaha ki te tangata, ā, ka tino whakatairanga i te hiahia o ngā kaihoko ki te hoko.
c. He manawanui pai.Ki te whakaritea ki te ngongo hiato konumohe-kirihou, he pai ake te pakari o te ngongo hiato kirihou katoa, e whakarite ana ka taea e te ngongo te hoki wawe ki tōna āhua taketake i muri i te pēhi i ngā mea whakapaipai, ā, ka mau tonu tōna āhua ataahua, āhua auau. He mea tino nui tēnei mō ngā takai whakapaipai.
Ngā ngoikoretanga:
Ko te āhuatanga ārai o te ngongo hiato kirihou-katoa e whakawhirinaki ana ki te momo me te matotoru o te rauemi paparanga ārai. Mēnā ka whakamahia a EVOH hei rauemi ārai o te ngongo hiato kirihou-katoa hei tauira, kia tutuki ai te ārai me te pakari ōrite, ko tōna utu he 20% ki te 30% teitei ake i te ngongo hiato konumohe. Mō te wā roa kei te heke mai, ka waiho tēnei hei take matua e whakawhāiti ana i te whakakapinga katoa o ngā ngongo hiato konumohe-kirihou ki ngā ngongo hiato kirihou-katoa.
