Ukusukela ngenkulungwane yama-21, imigangatho yokuphila yabantu iyaqhubeka iphucuka, ikwancamathela ukubaluleka okukhulu kwiingxaki zokusingqongileyo, kwaza kwazalwa ingxowa yeplastiki yokhuselo lokusingqongileyo, kwaye ngokukhawuleza ibe yintandokazi entsha yabantu.Nantsi intshayelelo elula kwinzuzo yobugcisa kwishishini lengxowa yokupakisha yeplastiki.

Kwi-2002, ibhetshi yeemveliso ezintsha kunye nobuchwepheshe obutsha bavela, kubandakanywa ukumelana nokunyamezela okuphezulu, ifilimu yeplastiki enemisebenzi emininzi, ukuphuhliswa kwefilimu ye-aseptic yokupakisha ngokukhawuleza, ifilimu ehlanganisiweyo yasekuqaleni iphuhlisa kwinqanaba elinzulu, ukwenza ingxowa, iteknoloji yokushicilela kwinqanaba elitsha. , kwixesha “lokuguquka kombala”.

Ukuphuhliswa kweteknoloji ye-multilayer co-extrusion itshintshe isakhiwo semveliso yefilimu esebenzayo kunye nesitya, kwaye ilungelelanise imfuno yemarike.Ngophuhliso loqoqosho lwentengiso, ukupakishwa kweemfuno zemihla ngemihla, ukupakishwa kwezithambiso, ukupakishwa kokutya, ukupakishwa kwezixhobo zekhaya kubeke phambili iimfuno eziphezulu.

Imifuno kunye neziqhamo ezitsha zokupakishwa kwefilim zentengiso yentengiso ebanzi, okwangoku, ifilimu ye-polyethylene kunye nefilimu ye-polypropylene yeyona nto isetyenziswa kakhulu iziqhamo kunye nemifuno yokupakisha imathiriyeli.Iziqhamo ezahlukeneyo kunye nemifuno ineemfuno ezahlukeneyo zeengxowa zokupakisha ezintsha.Ziziphi iingxowa zefilimu ezimele zikhethwe kule miba ilandelayo: ukunyanzeliswa kwegesi efanelekileyo kunye ne-O2 efanelekileyo kunye ne-CO2 yoxinaniso.Yongeza i-ethylene igesi yokufunxa.Ngokufunxa i-ethylene ekhutshwa sisiqhamo, icothisa ukuphefumla kwesiqhamo kwaye isigcine sisitsha.

Kungakhathaliseki ukuba leliphi ishishini leengxowa zokupakisha zeplastiki ukuze uphile kunye nokuvuselela okuqhubekayo.Sihlala sivelisa izinto ezintsha kwaye silungiselela iimveliso zethu ukuba sifune imakethi enkulu kukhuphiswano.
