I-Polyethylene yoxinaniso oluphantsi (LDPE) ukuzokuthi ga ngoku yeyona nto ixhaphakileyo isetyenziswa ngokwesithintelo imathiriyeli yokwaleka kwi-paperboard.I-Polylactic acid (i-PLA) yeyesibini kuyo, ibala ngaphezu kwe-5% yesabelo semarike kushishino, oluphuculweyo kakhulu xa kuthelekiswa neminyaka emi-5 edlulileyo.Nangona kunjalo, uphononongo lwakutsha nje kunye nophando kwi-bioplastics luqalise ukukhangela umphefumlo ngaphezulu kwe-PLA kunye ne-polybutylene adipate terephthalate (PBAT).Izinto ezintsha ezifunyanisiweyo zikwaphembelele kwisicelo sayo kwitafile ezilahlwayo.
Ngomhla wama-29 kaJuni ngo-2023, uLawulo lokuKhuselwa kokusiNgqongileyo (EPA) eTaiwan, lubhengeze ukuvalwa kokusetyenziswa kweetafile zetafile ezenziwe kwi-PLA, kwiindawo zokutyela, iivenkile ezithengisayo kunye namaziko aqhutywa nguwonke-wonke aqale ukusebenza nge-1 ka-Agasti ka-2023.
Ngeli xesha, uphuhliso lwezinto ezintsha ezisekwe kwibhayoloji luyaphumelela.Thatha i-PHA njengomzekelo.Kule mihla, iye yalwa iindlela zayo ukuya kwinqanaba lokuvelisa nangona iminyaka 'yokufunda ingqikelelo kunye novavanyo lwaselabhoratri.Kunyaka ophelileyo, iprojekthi yokuqala yeBluepha™️ eYancheng yaseJiangsu isungulwe kwimveliso kunye nemveliso yonyaka yeetoni ezingama-5,000.Kuyaphawuleka ukuba iiprojekthi zayo zesibini nezesithathu sele zisendleleni kunye nesikali somthamo wamashumi amawaka eetoni zebhayopolymer eyonakaliswayo yaselwandle.
Ukuqhutywa yimfuno evela kubathengi be-paperboard, imfuno yokuphuhlisa iingubo zamanzi njengemiqobo eyonakalisayo ifike phambili.Iphepha kunye nebhodi ziphawulwa njengezinto zokupakisha ezonakeleyo.I-Dispersion barrier coatings njengezisombululo zokunciphisa ukuthembela kwayo kumaleko eplastiki kwiipropati zomqobo zikhuphisana kakhulu kwaye zithembisa.Nangona kunjalo, ikamva elizinzileyo lekhonkco lexabiso liya kufuna utyalo-mali olongezelelekileyo kunye nophando olwenziwe lishishini ukuze kuphuhliswe izinto ezintsha kunye nokuphuculwa kwemveliso.
