Iyini i-PP Films?

IZAKHIWO

I-Polypropylene noma i-PP iyi-thermoplastic eshibhile ecacile kakhulu, icwebezela kakhulu futhi inamandla amahle okubamba. Inephuzu lokuncibilika eliphakeme kune-PE, okwenza ifaneleke ezinhlelweni ezidinga ukuhlanza emazingeni okushisa aphezulu. Iphinde ibe nomswakama omncane kanye nokukhanya okuphezulu. Ngokuvamile, izakhiwo zokuvala ukushisa ze-PP azilungile njengeze-LDPE. I-LDPE inamandla okudabuka angcono kanye nokumelana nokushisa okuphansi.

I-PP ingenziwa ngensimbi okuholela ekuthuthukisweni kwezakhiwo zokuvimba igesi ukuze kusetshenziswe ngokudingayo lapho isikhathi eside sokuphila komkhiqizo sibalulekile.Amafilimu e-PPzilungele kahle izinhlobo eziningi zezicelo zezimboni, zabathengi, kanye nezezimoto.

I-PP ingasetshenziswa kabusha ngokugcwele futhi ingacutshungulwa kalula ibe yimikhiqizo eminingi yezinhlelo zokusebenza eziningi ezahlukene. Kodwa-ke, ngokungafani nephepha neminye imikhiqizo ye-cellulose, i-PP ayiboli. Okuhle kakhulu, imfucuza ye-PP ayikhiqizi imikhiqizo eyingozi noma eyingozi.

Izinhlobo ezimbili ezibaluleke kakhulu yi-polypropylene e-cast unoriented (CPP) kanye ne-polypropylene e-biaxially oriented (BOPP). Zombili izinhlobo zine-gloss ephezulu, i-optics evelele, ukusebenza okuhle noma okuhle kakhulu kokuvala ukushisa, ukumelana nokushisa okungcono kune-PE, kanye nezakhiwo ezinhle zokuvimbela umswakama.

Amafilimu e-Cast Polypropylene (CPP)

I-Polypropylene (CPP) e-Cast unoriented ngokuvamile ithola izinhlelo zokusebenza ezimbalwa kune-polypropylene e-biaxially (BOPP). Kodwa-ke, i-CPP ibilokhu ithola indawo enhle kakhulu ekufakweni okuningi kwendabuko okuguquguquka kanye nezinhlelo zokusebenza ezingapakishiwe. Izakhiwo zefilimu zingenziwa ngokwezifiso ukuze zihlangabezane nezidingo ezithile zokupakisha, ukusebenza, kanye nokucubungula. Ngokuvamile, i-CPP inokumelana okuphezulu kokuklebhuka kanye nomthelela, ukusebenza okungcono kokushisa okubandayo kanye nezakhiwo zokuvala ukushisa kune-BOPP.

Amafilimu e-Polypropylene Aqondiswe Ngezinhlangothi Zombili (BOPP)

I-polypropylene eqondiswe ku-Biaxial noma i-BOPP1 yifilimu ye-polypropylene ebaluleke kakhulu. Iyindlela engcono kakhulu esikhundleni se-cellophane, iphepha elifakwe i-wax, kanye ne-aluminium foil. Ukuma kwandisa amandla okudonsa nokuqina, kunciphisa ukunwebeka (okunzima ukukwelula), futhi kuthuthukisa izakhiwo zokukhanya, futhi kuthuthukisa kancane izakhiwo zokuvimba umusi. Ngokuvamile, i-BOPP inamandla okudonsa aphezulu, i-modulus ephezulu (ukuqina), ukunwebeka okuphansi, isithiyo segesi esingcono, kanye nomswakama ophansi kune-CPP.

IZICELO

Ifilimu ye-PP isetshenziselwa izinhlelo eziningi zokupakisha ezivamile njengogwayi, amaswidi, ukudla okulula kanye ne-food wraps. Ingasetshenziswa futhi ekugoqeni okuncishisiwe, ama-tape liners, ama-diaper kanye ne-sterile wrap esetshenziswa ezinhlotsheni zezokwelapha. Ngenxa yokuthi i-PP inezakhiwo zokuvimba igesi ezimaphakathi kuphela, ivame ukumbozwa ngamanye ama-polymer afana ne-PVDC noma i-acrylic okuthuthukisa kakhulu izakhiwo zayo zokuvimba igesi.

Ngenxa yephunga eliphansi, ukumelana okuphezulu kwamakhemikhali kanye nokungangeni kahle, amazinga amaningi e-PP afanele ukusetshenziswa kokupakisha ngaphansi kwemithetho ye-FDA.
