1.I-Polyethylene Terephthalate (PET noma i-PETE)
Lena enye yamapulasitiki asetshenziswa kakhulu.Ayisindi, iqinile, ivamise ukuphumela obala futhi ivamise ukusetshenziswa emaphaketheni okudla nasezindwangu (i-polyester).
Izibonelo: Amabhodlela eziphuzo, amabhodlela okudla/izimbiza (isaladi esigaxekile, ibhotela lamantongomane, uju, njll.) kanye nezingubo ze-polyester noma intambo.
2.I-High-Density Polyethylene (HDPE)
Sekuhlangene, i-Polyethylene iwupulasitiki ojwayeleke kakhulu emhlabeni, kodwa ihlukaniswe ngezinhlobo ezintathu: Ukuminyana Okuphezulu, Ukuminyana Okuphansi kanye Nokuminyana Okuphansi Komugqa.I-High-Density Polyethylene inamandla futhi imelana nomswakama kanye namakhemikhali, okwenza ilungele amabhokisi, iziqukathi, amapayipi nezinye izinto zokwakha.
Izibonelo: Amabhokisi obisi, amabhodlela okuhlanza, amabhokisi okusanhlamvu, amathoyizi, amabhakede, amabhentshi asepaki namapayipi aqinile.
3.I-Polyvinyl Chloride (i-PVC noma iVinyl)
Le pulasitiki eqinile futhi eqinile imelana namakhemikhali kanye nesimo sezulu, okwenza kube nesifiso sokwakha nokwakha izicelo;kuyilapho iqiniso lokuthi ayiwubambi ugesi ikwenza kube yinto evamile ezisetshenziswa zobuchwepheshe obuphezulu, njengezintambo nekhebuli.Ibuye isetshenziswe kabanzi ezinhlelweni zezokwelapha ngenxa yokuthi ayingeneli emagciwaneni, ibulawa kalula amagciwane futhi inikeza ukusetshenziswa okukodwa okunciphisa izifo ekunakekelweni kwezempilo.Ngakolunye uhlangothi, kufanele siqaphele ukuthi i-PVC iyipulasitiki eyingozi kakhulu empilweni yomuntu, eyaziwa ngokukhipha ubuthi obuyingozi kuwo wonke umjikelezo wayo wokuphila (isb: umthofu, ama-dioxin, i-vinyl chloride).
Izibonelo: Amapayipi amanzi, amakhadi esikweletu, amathoyizi abantu nezilwane ezifuywayo, amathoyizi emvula, izindandatho zamazinyo, izikhwama zoketshezi ze-IV namashubhu ezokwelapha namamaski komoyampilo.
4.I-Low-Density Polyethylene (LDPE)
Inguqulo ethambile, ecacile, futhi evumelana nezimo ye-HDPE.Ivamise ukusetshenziswa njengolayini ngaphakathi kwamabhokisi eziphuzo, nasezindaweni zokusebenza ezimelana nokugqwala neminye imikhiqizo.
Izibonelo: Ukugoqa kwepulasitiki/okunamathelayo, amasemishi nezikhwama zesinkwa, ukugoqa amabhamuza, izikhwama zikadoti, izikhwama zegrosa nezinkomishi zeziphuzo.
5.I-Polypropylene (PP)
Lena enye yezinhlobo ezihlala isikhathi eside zepulasitiki.Ikwazi ukumelana nokushisa kunezinye, okwenza ilungele izinto ezifana nokupakishwa kokudla kanye nokugcinwa kokudla okwenzelwe ukubamba izinto ezishisayo noma ukuzifudumeza.Ivumelana nezimo ngokwanele ukuvumela ukugoba okuthambile, kodwa igcina isimo sayo namandla isikhathi eside.
Izibonelo: Utshani, amakepisi amabhodlela, amabhodlela kadokotela, izitsha zokudla okushisayo, itheyiphu yokupakisha, amanabukeni alahlwayo namabhokisi eDVD/CD (khumbula lawo!).
6.I-Polystyrene (PS noma i-Styrofoam)
Eyaziwa kangcono ngokuthi i-Styrofoam, le pulasitiki eqinile inenani eliphansi futhi igqumisa kahle kakhulu, okuyenze yaba yisisekelo sezimboni zokudla, zokupakisha nezokwakha.Njenge-PVC, i-polystyrene ibhekwa njengepulasitiki eyingozi.Ingakhipha kalula ubuthi obuyingozi njenge-styrene (i-neurotoxin), engamuncwa kalula ukudla futhi ngaleyo ndlela imukelwe abantu.
Izibonelo: Izinkomishi, iziqukathi zokudla okukhiphayo, ukupakishwa kwemikhumbi kanye nomkhiqizo, amabhokisi amaqanda, izinto zokusika kanye nokuvala amabhilidi.
7.Okunye
Ah yebo, inketho "enye" edume kabi!Lesi sigaba siwukubamba zonke ezinye izinhlobo zepulasitiki ezingezona ezanoma yiziphi ezinye izigaba eziyisithupha noma eziyinhlanganisela yezinhlobo eziningi.Siyifaka ngoba ngezinye izikhathi ungase uhlangabezane nekhodi engu-#7 yokugaya kabusha, ngakho-ke kubalulekile ukwazi ukuthi isho ukuthini.Okubaluleke kakhulu lapha ukuthi lawa mapulasitiki awajwayele ukugaywa kabusha.
Izibonelo: Izibuko zamehlo, amabhodlela ezingane nawezemidlalo, izinto zikagesi, ama-CD/DVD, izinto zokukhanyisa nezinto zokusika zepulasitiki ezicacile.
