Ifilimu yokutyaluhlobo lweemveliso zokupakisha zeplastiki, ezidla ngokwenziwa yipolymerization reaction nge ethylene njenge masterbatch.
Inokwahlulwa ibe ngamacandelo amathathu
Eyokuqala PE , Isetyenziselwa ikakhulu ukupakisha ukutya.Le filimu isetyenziselwa iziqhamo kunye nemifuno esihlala siyithenga, kubandakanywa neemveliso ezigqityiweyo ezithengwa kwivenkile enkulu.
Okwesibini yiPVC.Esi sixhobo sinokusetyenziselwa ukupakishwa kokutya, kodwa kunempembelelo ethile kukhuseleko lomzimba womntu;
Eyesithathu i-PVDC, esetyenziselwa kakhulu ukupakishwa kokutya okuphekiweyo, i-ham kunye nezinye iimveliso.
Yolula ifilimuiveliswa kusetyenziswa i-polyethylene LLDPE resin evela kumazwe angaphandle kunye nezongezo ezikhethekileyo zetackifier.
1. Ukusetyenziswa okwahlukeneyo
Ifilimu yokutya: Uluhlu olubanzi lokusetyenziswa, kubandakanya ukupakishwa kokutya, iziqhamo, imifuno, inyama, kunye nokupakishwa kwamanqaku.
Ifilimu eyolulayo: ukupakishwa, kunye nokupakishwa kwempahla ngexesha lokuthuthwa, ikakhulu ukuthintela ukuba izinto zisasazeke okanye zikrwele.
2. Iimpawu ezahlukeneyo
Ubunzima befilimu eyolulayo bukhulu kunefilimu yokutya, kwaye ubukhulu bukhulu kunefilimu yokutya.
Ukusongwa kweplastiki yasekhaya ngokuqhelekileyo yi-30cm ububanzi kunye ne-10um ubukhulu;Ifilimu eyolulayo yeshishini iqhele ukuba yi-50cm ububanzi kunye ne-20um ubukhulu.
3. Umlinganiselo wokwelula owahlukileyo
Ifilimu eyolulayo iyolula ngakumbi kunefilimu yokutya.Ifilimu eyoluliweyo ivuthelwa ngokuthe ngqo kwi-LDPE ngomatshini wokubumba, kwaye umlinganiselo wayo wolula unokufikelela kwi-300% -500%.Ngelo xesha, ifilimu yokubambelela inamathele kwinqaku, ngelixa ifilimu eyolulayo i-self-adhesive, ehambelana nobuninzi be-polyisobutylene esetyenzisiweyo.
I-LGLPAK igxile kuphando kunye nophuhliso kunye nokuveliswa kweemveliso zeplastiki, ukubonelela abathengi ngeemveliso ezanelisayo yinto esiyisukelayo.
