Ibhokisi yokutya okukhawulezayo yeplastiki elahlwayo luhlobo lwezixhobo ezicutshungulwa yi-resin okanye ezinye izinto ze-thermoplastic ngokusebenzisa ubuchwepheshe bokubumba i-injection yeplastiki eshushu eshushu. Ngokuphathelele izinto eziluhlaza, iibhokisi zokutya okukhawulezayo zeplastiki ezilahlwayo zahlulwe ngokubanzi zibe ziibhokisi zokutya okukhawulezayo ze-PP (polypropylene), ibhokisi yokutya okukhawulezayo ye-PS (Polystyrene) kunye nebhokisi yokutya okukhawulezayo ye-EPS (expanded polystyrene). Xa kuthelekiswa nezinye iintlobo ezimbini zezinto eziluhlaza, ibhokisi yokutya okukhawulezayo yeplastiki ye-PP inokumelana nobushushu obuphezulu. Yiyo kuphela ibhokisi yokutya okukhawulezayo enokufudumala kwi-oven ye-microwave. Ngenxa yokuzinza kwayo okuphezulu kweekhemikhali kunye nokumelana okuhle nokugqwala, inokusetyenziswa phantse kuzo zonke iziselo zokutya neziselo.
Ishishini leebhokisi zokutya ezikhawulezayo ezilahlwayo ikakhulu libonelela ngezinto eziluhlaza ezifana ne-PP, i-PE, i-EPS, kwaye i-midstream ngumvelisi weentlobo ngeentlobo zeebhokisi zokutya ezikhawulezayo. Iimveliso ezigqityiweyo zisetyenziswa kakhulu kwimarike yokupheka kunye nemarike yokuhanjiswa kokutya.
Ukusukela ngo-2019, ngokwengeniso yentengiso, iTshayina yeyona mveliso inkulu kwihlabathi yeebhokisi zokutya ezikhawulezayo zeplastiki ezilahlwayo, ibandakanya malunga ne-44.3% yeshishini leebhokisi zokutya ezikhawulezayo zeplastiki ezilahlwayo kwihlabathi liphela. Ngo-2019, ingeniso yentengiso yeebhokisi zokutya ezikhawulezayo zeplastiki ezilahlwayo eTshayina yayiyi-9.55 yeebhiliyoni zeerandi, apho izinga lokukhula konyaka elihlanganisiweyo ukusuka ngo-2014 ukuya ku-2019 yayiyi-22.0%.
Ngokwembono yesakhiwo sengeniso yokuthengisa yeebhokisi zokutya okukhawulezayo zeplastiki ezilahlwayo eTshayina ukususela ngo-2014 ukuya ku-2019, ishishini leebhokisi zokutya okukhawulezayo eTshayina lisekelwe kakhulu ekuthengisweni kweebhokisi zokutya okukhawulezayo zePP. Ngo-2019, iibhokisi zesidlo sasemini zePP zazibandakanya i-60.94% yemarike yeebhokisi zokutya okukhawulezayo ezilahlwayo.
