Ko ngā hāere haere ake o ngā rārangi e whakamāmā ana i ngā utu mo ngā mahi ā-tāngata, i te wā hoki ko te rerekētanga o te whakaputanga i raro i te micron e whakamāmā ana i ngā whakamātautau pūmau, mai i ngā tohu mō ngā taputapu pūtaiao ki ngā whakamātautau hāpai rongoā. Kāore te kōpae tāwhai mātua i te whakamāhinga o te hiko i te utu taumata—ko ia he whakamāngungu o ngā mahi e whakamāmā, e whakamārama, me ngā mahi e whakamārama ake i te taiao.

Te whakamātautau i ngā kōpae: BOPP, PET, me ngā kōpae nylon—te mātauranga, te pūmau o te hiko, me ngā whakamātautau o te whakamāmā
Ko te Biaxially Oriented Polypropylene (BOPP) he whakamātautau pai rawa i te wāhi o te āhua, me te utu iti, engari he iti ngā whakamātautau i runga ake i te 85°C—ā, he pai rawa tēnei mō ngā whakamātautau kai e kitea ana tonu, i ngā wā he iti ngā pānga o te hōhā. Ko te Polyethylene Terephthalate (PET) he pai ake i te whakamātautau o te hōhā (e taea ana te whakamātautau i te 150°C), me te iti o ngā whakamātautau, ahakoa he iti ake te whakamātautau o te āhua; ko tana whakamātautau o ngā āhua e whakamāhi ana i ngā rorohiko mātātoko, me ngā tohu whakamāhi. Ko te Nylon he pai rawa i te whakamātautau o ngā āhua, me te whakamātautau o te hōhā, engari he māmā ake te whakamātautau i te wai—ā, he pai rawa tēnei mō ngā wāhi o te motokā, me ngā wāhi o te whakamāhi i ngā mahi, i ngā wā he nui ake te kaha i te māmā o te wai.
