Iphakheji yemithi eyakhiwe ngokubandayo

Ucwecwe lwe-aluminium luyinto enhle yokupakisha eyikhemisi, kuyilapho ucwecwe lwe-aluminium olwakhiwe ngendlela ebandayo luyimpahla yokupakisha eyenziwe ngemithi esebenza kahle kakhulu.. Okokufaka kwemithi, ucwecwe olubandayo lwe-aluminium oluvame ukusetshenziswa yisakhiwo esine-laminated esihlanganisa izakhiwo zokuvikela ze-aluminium nezingqimba ezengeziwe ukuze kufezwe imisebenzi efana nokuvikela isithiyo., iyaphrinta, kanye nokubeka uphawu.

Isakhiwo esibandayo esilungele ukupakishwa kwemithi

Isakhiwo se-foil esibandayo semithi, ejwayelekile ucwecwe olubandayo lwe-aluminium emaphaketheni emithi ingase ibe nezingqimba ezilandelayo:

a. I-polyester (I-PET) ungqimba lwefilimu (12- 25 microns)

– Inhloso: esetshenziswa njengefilimu yenkampani yenethiwekhi ukuze inikeze amandla omshini kanye nendawo yokuphrinta.

– Izici: ukuzinza okuphezulu kwe-dimensional, indawo yokunyathelisa ebushelelezi, ukumelana kahle kwezinyembezi.

– Ubukhulu: 12- 25 microns, kuye ngezidingo zokuguquguquka namandla.

b. Isendlalelo sokunamathela (1- 3 microns)

– Inhloso: bopha ifilimu ye-polyester ku-aluminium foil.
– Izici: Ingcina esebenza ngokushisa isebenze noma ingcina ezwela ukucindezela eqinisekisa ibhondi evikelekile ngaphandle kokubeka engcupheni izici zokuvimbela zefoil..

c. Isendlalelo se-aluminium foil (6-9 ama-microns)

– Inhloso: Isebenza njengongqimba oluyisisekelo lokuvikela umuthi emswakama, ukukhanya, i-oxygen nezinye izinto ezingcolile.
– Izici: Isithiyo esiphezulu samagesi kanye nomswakama, ukukhanya okukhanyayo futhi okungewona ubuthi.
– Ubukhulu: 6-9 ama-microns (7imakrofoni,9imakrofoni)ubukhulu obujwayelekile bokufakwa kwefoyili ebandayo kwezemithi.

d. I-Seal seal coating/isendlalelo sokuqala (1-5 ama-microns)

– Inhloso: Ihlinzeka ngendawo engavalwa ngokushisa kumaphekhi amabhamuza noma amanye ama-substrates.
– Izici: Lesi sendlalelo sihambisana nosendlalelo sokuvala samafilimu e-PVC noma e-PVDC. Iqinisekisa uphawu oluvikelekile ngaphandle kokuthinta umuthi ngaphakathi.
– Uhlobo: Imvamisa i-lacquer yophawu lokushisa noma i-primer enamathela kahle ku-PVC, I-PVDC noma amanye ama-blister substrates avamile.

Isakhiwo se-foil esibandayo esithuthukisiwe

Kwezinye izimo, ucwecwe olubandayo lwe-aluminium lungase lube nezendlalelo ezengeziwe zokusebenza kangcono:

e. I-Protective coating (ngokuzikhethela, 1-2 ama-microns)
– Inhloso: Thuthukisa ukuhuzuka kanye nokumelana kwamakhemikhali kwe-foil.
– Izici: Nikeza umgoqo owengeziwe, kubaluleke kakhulu emithini yemithi ezwela kakhulu.

Isihluthulelo se-aluminium ebandayo yokupakishwa kwemithi

Icwecwe le-aluminium elakheke ngokubanda njengoba ukupakishwa kwangaphandle kwemithi kudinga ukuba nezici zokuvikela imithi kanye nokuvimbela izinto zangaphandle., ngakho-ke ukucatshangelwa okubalulekile kokufakwa kwe-foil ebandayo kwezemithi kuyizici ezine:
1. Umgoqo: Isendlalelo se-aluminium foil sinikeza umgoqo omuhle kakhulu ngokumelene nomswakama, umoya-mpilo kanye nemisebe ye-UV ukuvikela ukuzinza nokusebenza komuthi.
2. Ukuphrinta: Isendlalelo sefilimu ye-PET sivumela ilebula yekhwalithi ephezulu nokuphrinta komkhiqizo, okubalulekile ekuthotshelweni kwemithetho kanye nokuhlonza umkhiqizo.
3. Ukuhambisana: Isakhiwo kufanele sihambisane nemishini yokupakisha yemithi futhi sihlangabezane nezidingo zokulawula (isib. I-FDA, I-EMA).
4. Ukusebenza kokuvala: I-heat-seal coating kufanele iqinisekise uphawu oluqinile nge-blister packaging substrate (isib. I-PVC, I-PVDC-coated PVC noma i-Aclar® laminate).

Ibanga elijwayelekile lokujiya kwecwecwe elibandayo:

– Ifilimu ye-PET: 12- 25 microns
– Isendlalelo sokunamathela: 1- 3 microns
– I-aluminium foil: 6- 9 microns
– I-heat seal enamathela: 1-5 microns

Lesi sakhiwo sifinyelela ibhalansi phakathi kokuvikelwa kwesithiyo, ukuphrinta nokusebenza kahle kokuvala. I-aluminium eyakhiwe ngokubandayo ifaneleka kakhulu ezintweni zokupakisha zemithi ngenxa yokuhleleka kwayo., i-ductility enhle kakhulu, izindawo ezinhle kakhulu zokuvimbela, izindawo ezinhle zokuvala uphawu nezinye izinzuzo eziningi.
