Ko te HDPE he tirohanga poto mo te polietilini whakamahana. No reira, he kiko papatūānuku rawa atu rānei, he kiko porowhita. Mēnā e hiahia ana koe ki ngā mahi e hiahiatia ana ki te whakapakari me te whakangungu, ka whakamahi i te HDPE, nō reira ko tērā te kiko kaiwhakarite mō ngā waea miraka me ngā poaka taru, nā te mea kāore i te whakapae kia pire te rokiroki i roto i te kawe i ēnei rūma. Ka pai tēnei kiko hoki ki te tiaki i aua mea kua whakapiponohu i raro.
Ko te LDPE (low-density polyethylene) ko tētahi wāhanga keetoi. Kei te iti rawa atu te whanonga o tēnei kiko, kei te iti rawa atu hoki tana rangitikanga i runga i te HDPE (high density polyethylene). Whakamahia mai te LDPE mo ngā mahi ka hiahia ki te whakamahi i te itinga iti noa. Tauataina: Ko te LDPE ka whakamahia hei hanga i ngā kete kiko me ngā poaka kiki. Me whakamahia ā rā i ngā mea e hiahiatia ana ki te wawau me te wahoao, nō reira ko tērā te take i whakamahia ai te LDPE mo ēnei raru.
Nga Ngaehanga me nga Huiatanga o HDPE me LDPE Kia whakarongo mai ki te tuhinga tuatahi, ko HDPE. E pai rawa ana te āhua pai rawa o te HDPE, koia nei ko tana tino whakamana me te tūnoa. Ki te iti noa iho, ka taea e ia te tiaki i ngā hua i roto kia kitea ai. Ka whai huarahi anō hoki ia ki te whakatupu i te whiu me te rā. Kaore te HDPE i te whakawehewehe haere, e pai ana tērā mō ētahi atu hua.
I nāianei, tēnā whakamātau atu ki te LDPE. Ko te LDPE he aha rawa atu i te HDPE i tētahi wāhanga, ko tana tūmanako e tino nui ana. Ko ēnei pūtake korekore nei kei raro i te mea ka hiki pai hei whakarite i ngā mahi pakaging e hiahiatia ana te whakapīrangi, pērā i ngā pōro kētupeti me ngā pouaka kai. Heoi, ko te LDPE kaore e tino rangatira ana i te HDPE nā te itinga o tana huataunga, kāore anō hoki e taea i ngā hiahia katoa o te pakaging.
Ko te LDPE te whiringa matua mō te whakaritenga i ngā mea e hiahiatia ana te tūmanako me te whakapīrangi motuhake, engari mēnā e hiahiatia ana e koe te whakaritenga o ngā mea e tino tūpou kore ana, e kōwhiri ana i te kotiate, rānei e hiahiatia ana te kaiaraara, ka haere ai te HDPE hei whakaaturanga. Tēnā pea tēnei i te wā e kōrero ana i ngā pouaka plastic, e hiahiatia ana te whakatuwhera me te whakahaumanu i te tirohanga waimano. He nui ngā whakaaetanga e hiahiatia ana e koe i te wā e kōrero ana i te pakaging! Mō ngā mea e whakapaetia ana e ngā rongoā me te rā (pērā i ētahi rongoā), ko te HDPE te whiringa mōu, nā tērā e hangaia ana kia tino whakatika ki ngā rongoā me ngā UV.
Te whakawhitiwhiti kaihohi he tino huarahi pai ki te pērā i enei pūoro. He wā ka whakatū i ētahi hapori i ngā ratonga whakawhitiwhiti mō ngā pūoro HDPE me ngā pūoro LDPE. Ki te whakawhitiwhiti, tiakina kia hokiwhakapakari i te pūoro i mua atu. Ahakoa, māku koe ki te tango i ngā tohu rānei me ngā kape i mua i te kirimua o ngā taonga ki roto i te kete whakawhitiwhiti. Ko tēnā e mahi ai i te mahi whakawhitiwhiti i runga i te pai.
Ko te LDPE nō reira, he aha ake te pai mō ngā mahi e hiahiatia ana te wehewehe. Ko te polietēni iti whenuutanga (LDPE), hei tauira, ka whakamahia hei hanga i ngā kete pūoro me ngā pūkae whakawehewehe, nā te mea kāore i te whakarerekē, me te pai rawa ki te whakamahi. Ko te LDPE he pai rawa mō te kai e hiahiatia ana i te huringa wera. Ko tērā e whakaatu ai kia kaua te kai i te tahinga, nō reira kaua e kitea he kino ki te kai.
