Kwindawo eguquguqukayo yokupakishwa kokutya, apho ukhuseleko, ukwandiswa kobomi beshelufa, kunye nokuthembeka kwemveliso kudibana, izinzisi zolwelo ziye zavela njengamagorha angekavunywa. Ezi zongezo, zenzelwe ngobunono iifilimu zodidi lokutya, zidlala iindima ezininzi ezibaluleke kakhulu kwimpilo yabathengi kunye nokusebenza kakuhle kwezoshishino. Makhe sihlolisise imisebenzi emine engundoqo eyenza ukuba izinzisi zolwelo zibe yimfuneko ekupakishweni kokutya kwale mihla.
Ukuqina kweThermal: UkuKhusela iiFilimu kwi-Heat-inducedUkuthotywa
Iifilimu zodidi lokutya, nokuba yi-polyethylene (PE) okanye i-polypropylene (PP), ziphantsi kokulungiswa kobushushu obuphezulu (umzekelo, ukukhupha, ukubumba ukuvuthela) ukufikelela kwi-230 ° C.Izinzisi zolwelosebenza njengabagcini bobushushu, ukuthintela iiradicals zasimahla ezenziwe ngexesha lokuvezwa kobushushu. Uphononongo olwenziwa yi-Institute of Packaging Technologies lufumene ukuba ngaphandle kwezinzisi, iisampuli zefilimu zibonise ukuncipha kwe-35% kumandla obunzima emva kwemizuzu eyi-10 kwi-200 ° C. Ngokuphikisana,iifilimu ezinezinziso zolwelo oluphuculweyoImixube igcine ngaphezu kwe-90% yamandla ayo okuqala, iqinisekisa imfezeko yolwakhiwo ngexesha lokupheka okufana neetreyi zokutya ezifakwe kwi-microwave.
Ukwandisa uBomi beShelf: Ukunciphisa i-oxidation kunye nokuthotywa kwe-UV
Ngaphandle kokucutshungulwa, i-liquid stabilizers ilwa noxinzelelo lwendalo ngexesha lokugcinwa kunye nokuthutha. Imitha ye-UV kunye nokuba sesichengeni seoksijini kunokubangela i-photo-oxidation, ibangele iifilimu zibe tyheli kwaye zibembrittle. Umzekelo, kuvavanyo lokuthelekisa ukupakishwa kwetshiphu yeitapile, iifilimu ezinezongezo zolwelo ezizinzisa i-UV zandisa ubutsha bemveliso ngama-25%, njengoko kulinganiswe ngexabiso leperoxide. Ii-antioxidants ezisekwe kwi-asidi enamafutha kwizizinzi zolwelo zigalela ioksijini, ngelixa izinto zokufunxa i-UV ezifana ne-benzotriazoles zikhusela iifilimu kumonakalo wemitha, zigcina umtsalane wobuhle bepakethe kunye nexabiso lesondlo sokutya.
UkuqhubekekaUkwandiswa: Ukuphucula i-Melt Flow kunyeHomogeneity
Abavelisi bajongana nemingeni yokufikelela ubukhulu befilimu efanayo kunye nokugqiba komphezulu. I-stabilizers yolwelo inciphisa i-viscosity enyibilikayo ukuya kuthi ga kwi-18%, ngokweengxelo zeshishini, ivumela i-extrusion elula. Olu phuculo lubaluleke kakhulu kwimigca yemveliso enesantya esiphezulu, apho umahluko we-0.1 mm ubukhulu kunokukhokelela kwinkunkuma ebalulekileyo. Ngokukhuthaza ukufakwa kweplastiki okungaguqukiyo, izizinzisi zinciphisa iziphene ezinjengomphezulu wesikhumba sikakrebe kunye noguquguquka kobunzima, okukhokelela kugcino lweendleko kunye nokuphuculwa kwemveliso.
Ukuthotyelwa koMthetho: Ukuqinisekisa uKhuseleko lokuTya kunye noMthengiThembela
Ukhuseleko lweefilimu zodidi lokutya luxhomekeke kulawulo lokufuduka olongezelelweyo. Izizinzi zolwelo kufuneka zihambelane nemigaqo engqongqo, efana ne-US FDA 21 CFR 178.2010 kunye ne-EU Regulation (EC) No 10/2011. Umzekelo,i-calcium-zinc composite stabilizers, eziqinisekisiweyo njengezinye iindlela ezingeyiyo ityhefu kwiikhompawundi zemveli ezisekwe kwikhompawundi, zithobela imigangatho yoqhagamshelwano lwehlabathi lokutya. Amazinga abo asezantsi okufuduka (≤0.1 ppm kwiintsimbi ezinzima) abenza ukuba balungele ukupakishwa kokutya kweentsana, apho imida yokhuseleko ibaluleke kakhulu.
ILizwe Lekamva: Izinto ezintsha kwiTekhnoloji yokuZinzisa
Ishishini libona utshintsho olusingise kwizizinzisi zolwelo ezisekwe kwibhayoloji. Ioyile yeembotyi zesoya epoxidized, ephuma kwimithombo ehlaziyekayo, ngoku ithatha i-30% yesabelo semarike sokuzinzisa kwe-eco-friendly. Abaphandi baphinda baphonononge imiqulu emininzi edibanisa ukuzinzisa kunye neempawu ezisebenzayo, njengezakhono zokulwa ne-antimicrobial. Ezi nkqubela zithembisa ukucacisa ngokutsha ukhuseleko lokupakishwa kwemilinganiselo yozinzo.
Ukuqukumbela, izinzisi zolwelo azizongezo nje kuphela kodwa ziyinxalenye ebalulekileyo ekhusela ingqibelelo yokutya, imveliso elungelelanisiweyo, kunye nokuxhasa ukuthotyelwa kwemithetho. Njengoko imfuno yabathengi yokhuseleko, ukupakishwa okuhlala ixesha elide ikhula, ezi khompawundi ziguquguqukayo ziya kuqhubeka nokuvela, ziqhuba ukuqamba izinto ezintsha kwi-ecosystem yokupakisha.
