Ukutya ikusemkhenceniibhekisa kukutya okunemathiriyeli yokutya esele ilungiswe ngokufanelekileyo, ikhenkceziswe kubushushu-30 °, kwaye igcinwe kwaye isasazwe kubushushu be-18 °okanye ngaphantsi emva kokupakishwa.
Ngenxa yobushushu obuphantsi bokugcinwa kwetsheyini ebandayo kuyo yonke le nkqubo, ukutya okukhenkcezisiweyo kuneempawu zobomi obude beshelufa, engonakaliyo, kunye nosetyenziso olufanelekileyo, kodwa oku kuzisa imingeni enkulu kunye neemfuno eziphezulu zokupakisha izinto.
Ulwakhiwo lwezinto ezisetyenziswa kwisiqheloiingxowa zokupakisha ezikhenkcezisiweyokwimarike ngoku:
1. PET/PE
Esi sakhiwo sixhaphake kakhulu kwipakethe yokutya ekhenkcezayo ekhawulezayo.Inobungqina obungcono bokufuma, ukumelana nokubanda, kunye nobushushu obuphantsi bokuvala ubushushu, kwaye ixabiso liphantsi.
2.BOPP/PE, BOPP/CPP
Olu hlobo lolwakhiwo lububungqina bokufuma, luyamelana nokubanda, kunye nobushushu obuphantsi-lutywinwe ngamandla amakhulu kunye neendleko eziphantsi.Phakathi kwabo, i-BOPP / PE, ukubonakala kunye nokuvakalelwa kwesikhwama sokupakisha kungcono, okunokuphucula ibakala lemveliso.
3. I-PET/VMPET/CPE, BOPP/VMPET/CPE
Ngenxa yobukho be-aluminiyam-plated layer, umphezulu wesi sakhiwo uprintwe ngokugqibeleleyo, kodwa ukushisa okuphantsi kweqondo lokushisa kuncinci, kwaye ixabiso liphezulu, ngoko izinga lokusetyenziswa liphantsi.
4. NY/PE, PET/NY/LLDPE, PET/NY/AL/PE
Lo mqulu wesakhiwo uyaxhathisa kwiqhwa kunye neempembelelo.Ngenxa yobukho beNY umaleko, inokumelana nokugqobhoza okuhle, kodwa ixabiso liphezulu ngokwentelekiso.Ngokuqhelekileyo isetyenziselwa ukupakisha imveliso ye-angular okanye enzima.
Ukongezelela, kukho ezinye ezilulaIingxowa ze-PE, ezisetyenziselwa ukupakisha imifuno kunye neziqhamo, kunye neengxowa zokupakisha zangaphandle zokutya okufriziwe.Ukupakishwa kwe-PE ehlanganisiweyoikwayingxobo yokupakisha ehambelanayo nendalo enokuphinda isetyenziswe.
Iimveliso ezifanelekileyo kufuneka zibe nokupakishwa okufanelekileyo, iimveliso kufuneka zivavanywe, kwaye ukupakishwa kufuneka kuvavanywa nangakumbi.
