Ko ngā pounamu werohanga, he wāhanga matua o ngā ipu kirihou whakapaipai, e whakamahia whānuitia ana i roto i ngā takai tiaki kiri me te whakapaipai nā te mea he maha ngā painga, tae atu ki te hoahoa ngāwari, te pai o te whakaputa, te utu ka taea te whakahaere, me te mahi hiri pai rawa atu.

Polypropylene ngā pounamu whakapaipai kirihou he āhua mārama, he āhua pōuriuri hoki (me te tāpiri i ngā mea whakamārama), he iti te mātotoru (he māmā), he ātete matū pai rawa atu (ina koa ki ngā hinu me ngā whakarewa), he ātete wera pai (ka taea te whakahoromata ki te mamaoa), he pakeke teitei, he pakari pai, me te utu iti. Ko ngā ngoikoretanga ko te iti ake o te māramatanga ki te whakataurite ki te PETG/AS, te pakarukaru pea i ngā pāmahana iti, te ngawari ki te hihi UV (me tāpiri he mea whakaū UV), me te iti ake o te kanapa o te mata. Ka taea te whakamahi mō ngā ipu kirīmi, ngā pounamu hinu, ngā pounamu hopi horoi, ngā pounamu kaukau, ngā ngongo hinu, ngā taupoki, ngā wāhanga pane papu, me ētahi atu, ā, ko tētahi o ngā rauemi pounamu whakakoi werohanga whakapaipai e whakamahia whānuitia ana.

Polyethylene ngā pounamu whakapaipai kirihou, he mea hanga ki te HDPE, he āhua mārama, he pakeke, he pakari, he ātete matū pai (ina koa ki ngā waikawa me ngā kawakore), he iti te utu, me te ngāwari ki te tukatuka. He mea whakamahi noa ēnei mō ngā ipu kirīmi matotoru ake, ngā taupoki, me ngā pounamu kaukau nui. Ko te LDPE/LLDPE he āhua ngawari ake, he pakari ake, he mārama ake i te HDPE. He mea whakamahi noa mō ngā ngongo, ngā arai taupoki pounamu, me ngā tinana pounamu kua whakaputahia. Ka taea te whakamahi ki ngā takai mō ngā hua hopi horoi (te kaukau, te hopi horoi makawe), ngā ipu kirīmi, ngā momo taupoki pounamu (ina koa ngā taupoki/kīkī o roto e hiahia ana kia pai te hiri), me ngā ngongo.

PETG ngā pounamu whakapaipai kirihou he tino mārama, he kanapa (he rite ki te karāhe), he tino ātete ki te pānga, he pai te ātete ki ngā matū, he ngāwari ki te tā me te whakapaipai (te tā wera, te tā mata, me ētahi atu), me te āheinga ki te hangarua. He iti iho te pāmahana tukatuka i te PET. Ko ngā ngoikoretanga ko te utu nui ake i te PP/PE, te ātete wera ngawari (i raro iho i te 70°C), me te paku iti ake te pakeke ki te whakataurite ki te AS. Ka taea te whakamahi mō ngā pounamu serum kounga teitei, ngā pounamu toner, ngā pounamu hinu, ngā pounamu hinu kakara (ina hiahiatia he kakano rite ki te karāhe), me te takai me ngā whakaritenga whakaaturanga teitei. He whiringa rongonui mō te whakarei ake i te mana o te hua.

I werohia-whakakikoruatia ngā pounamu whakapaipai kirihou he kōwhiringa hangarau pakari, e whakamahia whānuitia ana, ā, he pai te utu i waenga i ngā rauemi tākai whakapaipai. He mea nui te māramatanga hōhonu ki ngā āhuatanga o te rauemi, ngā taipitopito tukanga, te hanganga utu, me ngā whakaritenga whakahaere kounga kia taea ai e ngā waitohu te hoahoa i ngā tākai e tutuki ai ā rātou hiahia, e haumaru ana, e pono ana, e whakataetae ana hoki, ā, kia taea ai e ngā kaihoko te whakahaere tika i te mekameka tuku, te whakahaere i ngā utu, me te whakaiti i ngā mōrearea.
