Ifilimu ehlanganisiweyo yokupakishwa kwefilimu (ifilimu yokupakisha elayitiweyo) iye yanda kakhulu kwiminyaka yakutshanje ngenxa yokusetyenziswa kwayo ngeendlela ezahlukeneyo kunye nokusebenza kakuhle. Olu hlobo lwezinto zokupakisha luqulunqwe ngamanqwanqwa amaninzi ezinto ezahlukeneyo ezisebenza kunye ukuze zenze umqobo ozinzileyo kunye osebenzayo ngokuchasene nezinto zangaphandle.
Umsebenzi wezinto ezihlanganisiweyo zokupakishwa kwefilimu ulele kumandla ayo okukhusela nokugcina imixholo ngaphakathi kwiphakheji. Olu hlobo lokupakisha luhlala lusetyenziselwa iimveliso zokutya, amayeza, kunye nezinye izinto ezibuthathaka ezifuna ixesha elide leshelufu kunye nokukhuselwa kubumanzi, ukukhanya, kunye neoksijini. Iingqimba zezinto ezidibeneyo zisebenza kunye ukuze zenze umqobo othintela imixholo ukuba ingachatshazelwa yimiba yangaphandle.
Ifilimu ehlanganisiweyo yokupakisha isetyenziswa kakhulu kumashishini ahlukeneyo anjengokutya, amayeza, kunye nempahla yabathengi. Ukupakishwa kunceda ukukhusela iimveliso ezivela kwizinto zangaphandle kwaye zigcine zintsha ixesha elide.
Ulwakhiwo lweMathiriyeli yeNdibaniselwanoe Ifilimu yokuPakisha
Ifilimu ehlanganisiweyo yokupakisha luhlobo lwefilimu yokupakisha eyenziwe ngamacandelo amabini okanye amathathu. Isakhiwo esinemigangatho emibini okanye emithathu yefilimu ehlanganisiweyo yokupakisha ngokuqhelekileyo idibaniswe yinkqubo edibeneyo. Phakathi kwabo, ulwakhiwo olunemigangatho emibini ngokubanzi luqulunqwe ngezinto ezimbini ezahlukeneyo.
Izinto ezisetyenziswa ngokuqhelekileyo kwiileya zeefilimu zokupakisha ezidibeneyo yi-polyethylene, i-polypropylene, i-polyester, i-nylon, i-aluminium foil kunye nephepha. I-Polyethylene kunye ne-polypropylene inika umswakama obalaseleyo kunye nokuchasana kweekhemikhali, ngelixa i-polyester inika amandla kunye nokuzinza. Ifoyile yeAluminiyam sisithintelo esihle kakhulu segesi kunye nokukhanya, ngelixa inayiloni ibonelela ngomqobo ophezulu weoksijini.
Uluhlu lokuqala lwesakhiwo semigangatho emibini ngokuqhelekileyo lwenziwe ngefilimu yeplastiki efana ne-polyethylene okanye i-polypropylene. Uluhlu lwesibini luyisithintelo sezinto ezifana ne-PET, okanye i-nylon. Umaleko womqobo ubonelela ngokhuseleko kumswakama, ioksijini, kunye nezinye izinto ezinokuwonakalisa imveliso. Iileyile ezimbini ke zihlanjululwe kunye zisebenzisa i-adhesive ekhethekileyo ukudala ifilimu edibeneyo, eqinile. Ngokomzekelo, ilula, yomelele kwaye ibhetyebhetye. Ikwangangeni manzi, imelana nobushushu, kwaye ineempawu ezintle zothintelo ngokuchasene neoksijini kunye nokufuma. Ezi zakhiwo zenza ukuba zilungele ukupakisha iimveliso ezifuna ukukhuselwa kokusingqongileyo.
Isakhiwo esinemigangatho emithathu yefilimu ehlanganisiweyo yokupakisha ifana nesakhiwo esinemigangatho emibini, kodwa inoluhlu olongezelelweyo olunika ukhuseleko olongezelelweyo. Uluhlu olongezelelweyo ludla ngokuba ngumaleko ophakathi owenziwe kwizinto ezahlukeneyo ezifana ne-aluminium foil okanye i-metalized foil. Olu luhlu lubonelela ngeempawu ezingcono zokuthintelwa ngokuchasene nokufuma kunye neoksijini kunesakhiwo esinemigangatho emibini. Oku kuyenza ilungele ukupakishwa kweemveliso ezifuna ukhuseleko olongezelelweyo, njengezinto ezibuthathaka ze-elektroniki, izixhobo zonyango, okanye amayeza.
Inkqubo edibeneyo esetyenziselwa ukudala i-two-layer okanye i-three-layer structure ye-composite packaging roll film yinkqubo enzima efuna iteknoloji ephezulu kunye nezixhobo. Kubandakanya ukudibanisa iiplastiki ezahlukeneyo kunye nezixhobo zokuthintela ukudala ifilimu eyomeleleyo, ehlala ixesha elide. Inkqubo ikwabandakanya ukongeza izongezo ezikhethekileyo ezifana ne-anti-static agents okanye i-UV stabilizers ukuphucula iimpawu zefilimu.
Ukongeza kwiipropathi zayo zokukhusela, ifilimu ehlanganisiweyo yokupakisha iphinda isetyenziswe ngokubanzi kuba ibiza imali kwaye kulula ukuyenza. Inkqubo edibeneyo esetyenziselwa ukudala ifilimu i-automated kakhulu, enceda ukunciphisa iindleko zabasebenzi kunye nokwandisa ukusebenza kakuhle kwemveliso. Ikwavumela abavelisi ukuba bavelise izixa ezikhulu zefilimu ngokukhawuleza nangokuqhubekayo.
Ububanzi beSicelo sefilimu yokuPakisha eDityanisiweyo
Esinye sezona zicelo zidumileyo zefilimu ehlanganisiweyo yokupakisha ikwishishini lokutya.
