Ifilimu eyolulayo, ekwabizwa ngokuba yifilimu eyolulayo kunye nefilimu yokuncipha kobushushu, yifilimu yokuqala yasekhaya eyoluliweyo ye-PVC eyaveliswa nge-PVC njengesiseko semathiriyeli kunye ne-DOA njengeplastiki kunye nokuzincamathela.Ngenxa yemicimbi yokhuseleko lokusingqongileyo, iindleko eziphezulu (ngokunxulumene nomlinganiselo ophezulu we-PE, indawo encinci yokupakisha iyunithi), ukunwebeka okungahambi kakuhle, njl., yapheliswa ngokuthe ngcembe xa ukuveliswa kwefilimu ye-PE yasekhaya yaqaliswa ukusuka kwi-1994 ukuya kwi-1995. Ifilimu ye-PE stretch okokuqala kusetyenziswa i-EVA njengezinto zokuzibamba, kodwa iindleko zayo zaziphezulu kwaye zinencasa.Kamva, i-PIB kunye ne-VLDPE zisetyenziswe njengezinto zokuzibamba, kwaye izinto ezisisiseko zaziyi-LLDPE, kuquka i-C4, i-C6, i-C8 kunye ne-metallocene PE (MPE).
Sebenzisa ifom:
1. Ukupakishwa okutywiniweyo
Olu hlobo lokupakisha lufana nokushwabana kwefilimu yokupakisha.Ifilimu isonga i-tray malunga ne-tray, kwaye emva koko ii-thermal grippers ezishushu zitywina ifilimu kuzo zombini iziphelo.Le yeyona ndlela yokuqala yokusetyenziswa kwefilimu eyolulayo, kwaye iifom zokupakisha ezininzi ziye zaphuhliswa ukusuka koku
2. Ukupakishwa kobubanzi obugcweleyo
Olu hlobo lokupakisha ludinga ukuba ifilimu ibe banzi ngokwaneleyo ukugubungela i-pallet, kwaye imilo yephalethi iqhelekile, ngoko ineyayo, ifanelekile kwifilimu yobunzima be-17 ~ 35μm.
3. Ukupakishwa ngesandla
Olu hlobo lokupakisha lolona hlobo lulula lokupakisha ifilimu eyolula.Ifilimu ifakwe kwi-rack okanye ibanjwe ngesandla, ijikelezwe yi-tray okanye ifilimu ijikeleze i-tray.Ikakhulu isetyenziselwa ukupakishwa kwakhona emva kokuba i-pallet esongiwe yonakele, kunye nokupakishwa kwepalethi eqhelekileyo.Olu hlobo lwesantya sokupakisha lucotha, kwaye ubukhulu befilimu obufanelekileyo bu-15-20μm;
4. Ukupakisha umatshini wokusonga ifilim
Le yeyona ndlela iqhelekileyo kwaye ibanzi yokupakisha ngoomatshini.I-tray iyajikeleza okanye ifilimu ijikeleza i-tray.Ifilimu igxininiswe kwisibiyeli kwaye iyakwazi ukunyuka naphantsi.Olu hlobo lomthamo wokupakisha lukhulu kakhulu, malunga neetreyi ezili-15-18 ngeyure.Ubukhulu befilimu obufanelekileyo bumalunga ne-15～25μm;
5. Ukupakishwa koomatshini okuthe tye
Ihluke kwezinye iipakethe, ifilimu ijikelezwe kwinqaku, elilungele ukupakishwa kwempahla ende, njengeekhaphethi, iibhodi, iiplanga zefiber, izinto ezikhethekileyo, njl.;
6. Ukupakishwa kweetyhubhu zephepha
Le yenye yezinto zamva nje zokusetyenziswa kwefilimu eyoluliweyo, ebhetele kunepakethe yetyhubhu yephepha yakudala.Ubukhulu befilimu obufanelekileyo yi-30～120μm;
7. Ukupakisha izinto ezincinci
Le yindlela yokupakisha yamva nje yefilimu eyolulayo, engenakunciphisa kuphela ukusetyenziswa kwezinto eziphathekayo, kodwa nokunciphisa indawo yokugcina iipalati.Kwamazwe angaphandle, olu hlobo lokupakisha lwaqala ukuqaliswa ngo-1984. Emva konyaka omnye kuphela, ezininzi iipakethe ezinjalo zavela kwimarike.Le fomu yokupakisha inamandla amakhulu.Ilungele ubukhulu befilimu ye-15～30μm;
8. Ukupakishwa kweetyhubhu kunye neentambo
Lo ngumzekelo wokusetyenziswa kwefilimu eyolulayo kwintsimi ekhethekileyo.Izixhobo zokupakisha zifakwe ekupheleni komgca wemveliso.Ifilimu yokwelula ngokuzenzekelayo ayinakuthatha indawo kuphela i-tape ukuze ibophe izinto eziphathekayo, kodwa iphinde idlale indima yokukhusela.Ubunzima obusebenzayo bu-15-30μm.
9. Ukolula uhlobo lokupakishwa kwendlela ye-pallet
Ukupakishwa kwefilimu eyoluliweyo kufuneka yolulwe, kwaye iifom zokwelula ze-pallet mechanical packaging ziquka ukunweba ngokuthe ngqo kunye nokwelula kwangaphambili.Kukho iindidi ezimbini zokolulwa kwangaphambili, enye i-roll pre-stretching kwaye enye i-electric stretching.
