Ikakhulukazi kukhona4 izinhlobo zefilimu yokugqoka esetshenziswa kuPP izikhwama ezilukiweyo. Izinhlobo zefilimu yokugqoka kanye nezakhiwo zayo ziyizidingo zokuqala zesikhwama esilukiwe se-PP.

Lezi zidinga ukwazi ngaphambi kokukhetha impahla yefilimu engcono kakhulu.

Ngokuya ngezidingo zomsebenzisi, izinhlobo ezinhlanu zefilimu enamathelayo noma ifilimu elaminethiweyo zisebenzisa kuisikhwama se-polybagukukhiqizwa.

Izinhlobo zefilimu ezisetshenziswa kakhulu yileziifilimu ye-pearl, ifilimu ye-Aluminium, ifilimu ye-matte, nefilimu ye-BOPP.

Izinhlobo ezahlukene zamafilimu zinezimfanelo ezihlukene ngakho zilungele ukusetshenziswa ngokuhlukile.

Umehluko walezi zinto zefilimu wenza i-polybag elukiwe ifanele ukupakishwa komkhiqizo othile.

1. Pearl Film:

Uma udinga isikhwama esinezimfuneko zombili zobufakazi bomswakama futhi obuphrintekayo, isikhwama se-PP esenziwe ngefilimu se-pearl singase sibe ngcono kakhulu phakathi kwazo zonke ezinye izikhwama ze-laminated.

Lapha, ungqimba lwe-polypropylene noma ifilimu enamathiselwe ezinhlangothini zombili zendwangu ye-PP elukiweyo, futhi umphumela uvela obala ngokudala isikhalazo esihle kakhulu sokuthengisa kanye nezinsiza zokuphrinta. Ifilimu ye-polypropylene ingaxhunyaniswa kalula nendwangu eyisisekelo ngenqubo ebizwa ngokuthi ukusetha ukushisa. Ukugqoka ngale nqubo nakho kubiza kakhulu. Ijazi lefilimu ye-pearl lifakazela umswakama, ukufiphaza, nokulwa nokubola.

Yingakho ingasetshenziselwa izinjongo eziningana. Izinto zokudla njengerayisi, ufulawa, noma ezinye izinto eziyimbudumbudu zingagcina kalula kulokhuisikhwama camera. Lesi sikhwama sidume kakhulu ekuphatheni impahla yezolimo, umanyolo wamakhemikhali, nokudla kwenkukhu.

2. Ifilimu ye-Aluminium:

Ifilimu ye-aluminium ingasebenzisa ebusweni noma ngemuva kwesikhwama esilukiwe se-PP.

Ukufakwa kwe-aluminium foil kuthuthukisa izici zokusebenza zesikhwama esilukiwe se-pp.

Inzuzo eyinhloko ivela endaweni yokushisa ukushisa kwe-aluminium foil. Ngenxa yokuncipha kokushisa okuphansi, izikhwama ezilukiwe ze-PP ziba namandla futhi zihlala isikhathi eside kunezikhwama ezijwayelekile.

IIsikhwama se-PP esiboshwe nge-aluminiumidume ngokufakwa kwempahla engangeni manzi, ukupakishwa kwemikhiqizo yokudla, nokunye ukupakishwa kwezinto okwakudinga umgoqo owanele.

Le nto yokumboza yenza isikhwama esilukiweyo se-pp sibe phezulu ngokwezinga lokumelana nokushisa. Ingasetshenziselwa ukupakisha ukudla okubucayi lapho ukugcinwa kokulawula izinga lokushisa kuyisidingo esiphezulu njengezinto zobisi noma izimpahla zikagwayi.

3. Ifilimu ye-Matte:

Izakhiwo ezihlukile zalezi zikhwama zokugqoka zihlanganisa izindawo eziningana. Iisikhwama esilukiwe se-PP esifakwe mattealikwazi umswakama futhi lingasetshenziselwa ukugcina ukudla noma imikhiqizo yezolimo.

Impahla yokumelana nokwelula yale filimu iphakeme ngokwanele eyenza izindawo ezingcono zokunwebeka kuzo zombili izikhombisi-ndlela ze-longitudinal neziphambene.

Lokho kwenza isisekelo sendwangu siqine futhi sithuthukise umthamo wokuthwala umthwalo wesikhwama esilukiwe se-PP. Isikhwama sefilimu se-matte laminated sidume ngokupakisha izinto zokudla ngamanani amancane.

Kungenxa yezakhiwo ezinhle kakhulu zokuphatha zefilimu yokupakisha. Iyakwazi ukumelana nokushisa futhi inokubukeka okucwebezelayo okuphezulu.

Iphinde idale umgoqo womoya-mpilo okuyindawo enenzuzo ebalulekile yokugcina ukudla nemikhiqizo yezolimo.

4. Ifilimu ye-OPP:

Ifilimu ejwayeleke kakhulu esetshenziselwa ukufaka izikhwama ze-poly ezilukiweyo izikhwama ze-OPP noma ze-BOPP.

I-OPP esikhundleni sefilimu ye-Orientated Polypropylene. Le filimu iphakethe enezinto eziningi ezifanele eziyenza ilungele ukupakisha izinto zokudla.

Impahla yokupakisha ukudla kufanele ivikele izakhiwo ezinomsoco kuze kube yilapho isetshenziswa ekugcineni.

Lokho kuhlanganisa nokumelana okwanele kumswakama, ukukhanya kwelanga, ne-gaseous matter. Ifilimu futhi idinga ukuthuthukisa isikhalazo sokudayiswa futhi kufanele yonge futhi. Zonke izidingo zingatholwa kusetshenziswa ifilimu ye-BOPP esikhwameni se-poly esilukiwe.

Izinhlobo ezahlukene zamafilimu zinezimfanelo ezihlukene ngakho zilungele ukusetshenziswa ngokuhlukile. Umehluko walezi zinto zefilimu wenza i-polybag elukiwe ifanele ukupakishwa komkhiqizo othile.

Izikhwama ezilukiwe ze-PP zisebenzisa izinhloso ezimbalwa, yingakho izakhiwo ezidingekayo ekusetshenzisweni ngakunye zihlukile.

Ngokuphazima kweso, aisikhwama sokupakisha ukudlafuthi ifilimu yayo eboshiwe idinga iziqu ezinjalo ukuze ikwazi ukuvikela izakhiwo ezinomsoco.

Izinto zokupakisha zomkhiqizo oyimbudumbudu noma oyimpuphu zidinga izakhiwo ezinjalo ukuze zikwazi ukuvimbela ukuvuza nokusabalala kwe-granular.

I-liquid reservoir idinga ukuqedwa okuphelele kobufakazi bamanzi okutholwe ezintweni ezithile zokumboza.

Ngenxa yezakhiwo eziguqukayo ezidingekayo zezikhwama ezilukiwe ze-pp, izinto zefilimu ezisetshenziselwa ukugqoka nazo zihlukile.

Amanye amafilimu nawo asetshenziselwa ukugqoka ngesikhwama esilukiwe se-PP kodwa, ukusetshenziswa kwabo kulinganiselwe. Enye ifilimu ifilimu elwa namagciwane, ifilimu elwa namagciwane, ifilimu ye-LDPE, ifilimu ye-MDPE,

Ifilimu ye-HDPE, ifilimu yePolystyrene, ifilimu yokukhishwa kweSilicone nefilimu engalukiwe ngezinye zakho.
