Ibhokisi lokudla elisheshayo lepulasitiki elilahlwayo liwuhlobo lwezitsha ezicutshungulwa yi-resin noma ezinye izinto ezisetshenziswayo ezishisayo ngobuchwepheshe bokubumba umjovo wepulasitiki obushisa kakhulu obusezingeni eliphezulu.Ngokuya ngezinto zokusetshenziswa, amabhokisi okudla okusheshayo epulasitiki alahlwayo ahlukaniswa ikakhulukazi amabhokisi okudla okusheshayo e-PP (polypropylene), i-PS (Polystyrene) ibhokisi lokudla okusheshayo kanye ne-EPS (i-polystyrene eyandisiwe) ibhokisi lokudla okusheshayo.Uma kuqhathaniswa nezinye izinhlobo ezimbili zezinto zokusetshenziswa, ibhokisi lokudla elisheshayo lepulasitiki le-PP linokumelana nokushisa okuphezulu.Iwukuphela kwebhokisi lokudla okusheshayo elingashiswa kuhhavini we-microwave.Ngenxa yokuqina kwayo kwamakhemikhali aphezulu kanye nokumelana nokugqwala okuhle, ingasetshenziswa cishe kukho konke Ukudla neziphuzo.
Imboni ekhuphukayo yomkhakha wamabhokisi okudla okusheshayo alahlwayo ikakhulukazi abahlinzeki bezinto ezingavuthiwe ezifana ne-PP, PE, EPS, kanti i-midstream ingumkhiqizi wezinhlobo ezahlukene zamabhokisi okudla okusheshayo.Imikhiqizo eqediwe isetshenziswa kabanzi emakethe yokudla kanye nemakethe yokulethwa kokudla.
Kusukela ngo-2019, ngokwemali engenayo yokuthengisa, iChina ingumkhiqizi omkhulu kunayo yonke emhlabeni wamabhokisi okudla okusheshayo epulasitiki alahlwayo, ebalwa cishe ngama-44.3% embonini yamabhokisi okudla okusheshayo epulasitiki alahlwayo emhlabeni jikelele.Ngo-2019, imali yokuthengisa yamabhokisi okudla okusheshayo epulasitiki alahlwayo eChina yayingama-yuan ayizigidi eziyizinkulungwane ezingama-9.55, lapho izinga lokukhula konyaka elihlanganisiwe ukusuka ku-2014 kuya ku-2019 lalingama-22.0%.
Ngokombono wesakhiwo semali engenayo yokuthengisa yamabhokisi okudla okusheshayo epulasitiki alahlwayo e-China kusukela ngo-2014 kuya ku-2019, imboni yamabhokisi okudla okusheshayo e-China isekelwe ikakhulukazi ekuthengisweni kwamabhokisi okudla okusheshayo e-PP.Ngo-2019, amabhokisi esidlo sasemini e-PP abalelwa ku-60.94% wemakethe yamabhokisi okudla alahlwayo.
