Ngokuthuthuka okusheshayo komnotho wezenhlalo, ukupakishwa kwamaphepha kuye kwathatha isikhundla esibaluleke kakhulu ezintweni ezihlukahlukene zokupakisha, ikakhulukazi uchungechunge lwemikhiqizo yeziqukathi zephepha. Iziqukathi zephepha zingaklanywa ngezinhlobo ezahlukene ezifana namabhokisi, izinkomishi, izitsha, njll. Ngenxa yokuthi isiqukathi sephepha ngokwaso sinezici zokuphepha, inhlanzeko, ezingenabuthi, ezingenaphunga, ezingangcolisi, ezibolayo, njll., sihambisana ne umkhuba wamanje wokuvikelwa kwemvelo futhi iyinto yokupakisha ephephile esetshenziswa kabanzi kuukupakisha ukudlaimboni.
Ngenxa yezinhlobo ezahlukene zokucubungula zeziqukathi zephepha, kunezidingo ezihlukene zephepha, ngakho-ke kubaluleke kakhulu ukujwayelana nezici ze-cupstock ukuze zicutshungulwe. Okuvame ukusetshenziselwa izinkomishi zephepha kanyeizitsha zephepha.
Izinto ezisetshenziselwa izinkomishi zeziphuzo ezishisayo ngokuvamile zenziwe ngephepha lesisekelo kanye ne-PE coating eyodwa, eyodwaI-PE coated cupstock . Ngokuvamile, iphrintwa endaweni yephepha elingelona i-PE. Ngenxa yezidingo zeziphuzo ezishisayo, imikhiqizo enjalo idinga ukuba nesilinganiso esithile sokushisa okushisayo ngemva kokucubungula. Ngakho-ke, le mikhiqizo ngokuvamile idinga ukushuba okuthile nokuqina kwephepha ukuze kwandiswe ukufakwa kwe-thermal. Umthamo omkhulu, iphepha elisetshenziswayo liyajiya.
Izinkomishi zeziphuzo ezibandayo zihlukaniswe izinhlobo ezimbili ngenxa yezindlela ezihlukene zokucubungula. Enye iwukwenza iphepha libe ne-anti-permeability enhle ngokusebenzisa inqubo yokucwilisa i-wax ngemva kokuba iphepha eliyisisekelo liphrintiwe futhi lenziwe inkomishi; enye iwukwenza iphepha lingangeneli ngokuhlanganisa i-PE nhlangothi zombili zephepha. Izidingo zokuphrinta zezinhlobo ezimbili ezihlukene zokucubungula zezinto zihlukile. Ukuphrinta okucutshungulwe ngendlela ye-wax yokucwilisa kuphrintwa ebusweni bephepha. Ngokuqondene nokuphrinta ngokwako, azikho izidingo ezikhethekile zezinto zokusetshenziswa. Ephepheni ngemuva kokuhlanganiswa kwe-PE ehlangene kabili, kuyadingeka ukuhlanganisa iphepha ngokwelashwa okukhethekile ukuze uthole umphumela omuhle wokunyathelisa.
I-Cupsstock isetshenziswa kabanzi embonini yokupakisha ukudla, ngakho ukukhethwa kukayinki akugcini nje ngokuhlangabezana nezidingo zokunyathelisa ngokwako, kodwa futhi kudinga ukuthi izingxenye zikayinki kufanele zihlangabezane nomthetho wokuhlanzeka kokudla kanye nezindinganiso zokuhlanzeka zokupakisha ukudla. Ukusetshenziswa kwama-solvents akudingi iphunga elingavamile kanye nenani elincane le-solvent esele, ukuze imikhiqizo ephrintiwe yomiswe ngokushesha futhi igweme izinkinga ezifana nokunamathela okubi okungenzeka ngesikhathi sokwenza indebe elandelayo.
