Zeziphi imathiriyeli zeengxowa zokupakisha ukutya?

I-PE (iPolyethylene)
Iimpawu: Uzinzo oluhle lweekhemikhali, ezingenayo ityhefu, ukucaca okuphezulu, kunye nokumelana nokubola ngama-asidi amaninzi kunye ne-alkali. Ukongeza, i-PE inesithintelo esihle segesi, isithintelo seoyile kunye nokugcinwa kwevumba elimnandi, elinceda ukugcina ukufuma ekutyeni. Iplastiki yayo nayo ilungile kakhulu, kwaye akulula ukuyikhubaza okanye ukuyiqhawula njengesixhobo sokupakisha.
Isicelo: Isetyenziswa ngokuqhelekileyo kwipakethe yeplastiki yokutya.

PA (Nayiloni)
Iimpawu: Ukumelana nobushushu obuphezulu, ukuchasana nokubhoboza, ukusebenza kakuhle komqobo weoksijini, kwaye ayiqulathanga izithako eziyingozi. Ukongeza, imathiriyeli ye-PA inamandla, ayinyangeki, ayinyangeki ngeoyile, ineempawu ezintle zoomatshini kunye nokuqina, kwaye inokumelana nokuhlatywa kakuhle kunye neziphumo ezithile zokuchasa ukubola kunye ne-antibacterial.
Isicelo: Ingasetyenziselwa ukupakishwa kokutya, ngakumbi ukutya okudinga umqobo ophezulu we-oksijini kunye nokumelana nokubhoboza.

I-PP (ipolypropylene)
Iimpawu: I-PP yebakala lokutya ayiyi kukhulula izinto ezinobungozi nakwiqondo lokushisa eliphezulu. IPlasitiki yePP iyabonakala, ineglosi elungileyo, kulula ukusetyenzwa ngayo, ikrazuka kakhulu kwaye iyaxhathisa, ayivani namanzi, ixhathisa ukufuma, kwaye iyakwazi ukumelana nobushushu obuphezulu, kwaye inokusetyenziswa ngokuqhelekileyo kwi-100 ° C ~ 200 ° C. Ukongeza, iplastiki yePP kuphela kwemveliso yeplastiki inokufudunyezwa kwi-oven microwave.
Isicelo: Ngokuqhelekileyo zisetyenziswa kwiingxowa zeplastiki ezikhethekileyo zokutya, iibhokisi zeplastiki, njl.

I-PVDC (i-polyvinylidene chloride)
Iimpawu: I-PVDC inokuqina komoya okulungileyo, ukunqanda amadangatye, ukuxhathisa ukubola, ukhuseleko kunye nokukhuselwa kokusingqongileyo, kwaye ihlangabezana neemfuno zococeko lokutya. Ukongeza, i-PVDC nayo inokumelana nemozulu elungileyo kwaye ayizukuphela nokuba ivezelwe ngaphandle ixesha elide.
Isicelo: Isetyenziswa kakhulu kwipakethe yokutya kunye nesiselo.

I-EVOH (i-ethylene/vinyl alcohol copolymer)
Iimpawu: ukungafihli kakuhle kunye negloss, iipropathi ezinamandla zokuthintela igesi, kwaye zinokuthintela ngokufanelekileyo umoya ukuba ungangeni kwipakethe ukonakalisa ukusebenza kunye nomgangatho wokutya. Ukongeza, i-EVOH ayinyangeki ngokubanda, ayinxibi, iyalastiki kakhulu, kwaye inamandla aphezulu.
Isicelo: isetyenziswa ngokubanzi kwipakethe ye-aseptic, iitoti ezishushu, iibhegi zokubuyiswa, ukupakishwa kweemveliso zobisi, inyama, ijusi enkonkxiweyo kunye ne-condiments, njl.

Ifilimu egqunywe ngeAluminiyam (i-aluminiyam + PE)
Iimpawu: Ifilimu efakwe kwi-aluminium yinto ehambelana nokusingqongileyo. Inxalenye ephambili yengxowa yokupakisha edibeneyo i-aluminium foil, eyisilivere-emhlophe, i-non-toxic kunye ne-tasteless, i-oyile-resistant kunye neqondo lokushisa, ithambileyo kunye neplastiki, kwaye inomqobo olungileyo kunye neempawu zokutywinwa kobushushu. Ukongeza, ifilimu ene-aluminised inokuthintela ukutya kurhwaphilizo lwe-oxidative kwaye ithintele ukungcoliseka kwendalo, ngelixa igcina ukutsha kunye nencasa yokutya.
Isicelo: isetyenziswa ngokubanzi kwintsimi yokupakisha ukutya.
