LETLOTLO

Polypropylene kapa PP ke thermoplastic e theko e tlaase ea ho hlaka ho phahameng, botlolo bo phahameng le matla a matle a ho tsitsa. E na le sebaka se phahameng sa ho qhibiliha ho feta PE, e leng se etsang hore e tšoanelehe bakeng sa lisebelisoa tse hlokang sterilization mocheso o phahameng. E boetse e na le moholi o fokolang le ho phatsima ho holimo. Ka kakaretso, thepa ea ho koala mocheso ea PP ha e ntle joaloka ea LDPE. LDPE e boetse e na le matla a betere a ho tabola le ho hanyetsa mocheso o tlase.

PP e ka etsoa metallized e hlahisang thepa e ntlafetseng ea thibelo ea khase bakeng sa lits'ebetso tse hlokang moo bophelo ba nako e telele ea lihlahisoa bo leng bohlokoa.Lifilimi tsa PPli loketse mefuta e mengata e fapaneng ea lits'ebetso tsa indasteri, bareki le likoloi.

PP e sebelisoa hape ka botlalo 'me e ka sebelisoa habonolo lihlahisoa tse ling tse ngata bakeng sa lits'ebetso tse fapaneng tse fapaneng. Leha ho le joalo, ho fapana le pampiri le lihlahisoa tse ling tsa cellulose, PP ha e khone ho senyeha. Ka lehlakoreng le leng, litšila tsa PP ha li hlahise lihlahisoa tse chefo kapa tse kotsi.

Mefuta e 'meli ea bohlokoa ka ho fetisisa ke polypropylene e sa tloaelehang (CPP) le biaxially oriented polypropylene (BOPP). Mefuta ena ka bobeli e na le khanya e phahameng, optics e ikhethang, ts'ebetso e ntle kapa e ntle ea ho koala mocheso, ho hanyetsa mocheso ho feta PE, le thepa e ntle ea thibelo ea mongobo.

Lifilimi tsa Cast Polypropylene (CPP)

Cast unoriented Polypropylene (CPP) hangata e fumana lits'ebetso tse fokolang ho feta biaxially oriented polypropylene (BOPP). Leha ho le joalo, CPP e ntse e tsoela pele ka mokhoa o tsitsitseng e le khetho e babatsehang mekhoeng e mengata ea setso e feto-fetohang hammoho le lits'ebetso tse sa phutheng. Thepa ea filimi e ka etsoa ka mokhoa o ikhethileng ho fihlela litlhoko tse ikhethileng tsa ho paka, ts'ebetso le ts'ebetso. Ka kakaretso, CPP e na le khanyetso e phahameng ea meokho le tšusumetso, ts'ebetso e ntle ea mocheso o batang le thepa ea ho koala mocheso ho feta BOPP.

Lifilimi tsa Polypropylene tsa Biaxially Oriented Polypropylene (BOPP)

Biaxially oriented polypropylene kapa BOPP1 ke filimi ea bohlokoa ka ho fetisisa ea polypropylene. Ke khetho e ntle ho feta cellophane, pampiri e entsoeng ka boka, le foil ea aluminium. Thepa e eketsa matla le ho satalla, e theola bolelele (ho thata ho otlolla), 'me e ntlafatsa thepa ea optical,' me ka mokhoa o itseng e ntlafatsa thepa ea thibelo ea mouoane. Ka kakaretso, BOPP e na le matla a phahameng a ho tsitsa, modulus e phahameng (ho satalla), bolelele bo tlase, tšitiso e ntle ea khase, le moholi o tlase ho feta CPP.

 

LIKOPO

Filimi ea PP e sebelisetsoa lisebelisoa tse ngata tse tloaelehileng tsa ho paka tse kang lisakerete, lipompong, li-snack le liphutheloana tsa lijo. E ka boela ea sebelisoa bakeng sa ho phuthela ho honyela, lithapo tsa theipi, maleiri le sekoaelo se hloekisitsoeng se sebelisoang lits'ebetsong tsa bongaka. Hobane PP e na le thepa e thibelang khase feela, hangata e koahetsoe ka lipolymer tse ling tse joalo ka PVDC kapa acrylic e ntlafatsang haholo thepa ea eona e thibelang khase.

Ka lebaka la monko o tlase, khanyetso e phahameng ea lik'hemik'hale le ho se sebetse hantle, limaraka tse ngata tsa PP li loketse ho paka lits'ebetso tlasa melaoana ea FDA.
