I-Polypropylene okanye i-PP yindleko ephantsi ye-thermoplastic yokucaca okuphezulu, i-gloss ephezulu kunye namandla afanelekileyo okuqina.Inomlinganiselo ophezulu wokunyibilika kune-PE, eyenza ukuba ifaneleke kwizicelo ezifuna inzala kumaqondo obushushu aphezulu.Ikwanayo nenkungu encinci kunye neglosi ephezulu.Ngokubanzi, iimpawu zokutywinwa kobushushu zePP azilunganga njengezo ze-LDPE.I-LDPE ikwanamandla angcono okukrazula kunye nokumelana nefuthe lobushushu obuphantsi.
I-PP inokuthi yenziwe ngetsimbi ekhokelela ekuphuculweni kweepropati zokuthintela igesi kwizicelo ezifunwayo apho ixesha elide leshelufu libalulekile.Iifilimu ze-PP zifaneleke kakuhle uluhlu olubanzi lwemizi-mveliso, abathengi, kunye nosetyenziso lweemoto.
I-PP inokuphinda isetyenziswe ngokupheleleyo kwaye inokuphinda ihlaziywe ngokulula kwezinye iimveliso ezininzi ezahlukeneyo zosetyenziso.Nangona kunjalo, ngokungafaniyo nephepha kunye nezinye iimveliso ze-cellulose, i-PP ayinayo i-biodegradable.Kwi-upside, inkunkuma yePP ayivelisi imveliso enetyhefu okanye eyingozi.
Iintlobo ezimbini ezibalulekileyo ziphosa i-polypropylene (CPP) kunye ne-biaxially oriented polypropylene (BOPP).Zombini ezi ntlobo zineglosi ephezulu, i-optics ekhethekileyo, ukusebenza kakuhle okanye okugqwesileyo kokutywinwa kobushushu, ukumelana nobushushu obungcono kune-PE, kunye neempawu ezintle zokuthintela ukufuma.
Iifilimu zeCast Polypropylene (CPP)
I-Cast unoriented Polypropylene (CPP) ifumana ngokubanzi izicelo ezimbalwa kune-biaxially oriented polypropylene (BOPP).Nangona kunjalo, i-CPP ibisoloko ifumana umhlaba njengokhetho oluhle kakhulu kwiipakethi ezininzi zemveli eziguquguqukayo kunye nezicelo ezingapakishwanga.Iipropathi zefilimu zinokwenziwa ngokwezifiso ukuze zihlangabezane nokupakishwa okuthe ngqo, ukusebenza, kunye neemfuno zokuqhuba.Ngokubanzi, i-CPP inokukrazula okuphezulu kunye nokuchasana kweempembelelo, ukusebenza ngcono kobushushu obubandayo kunye neempawu zokutywinwa kobushushu kune-BOPP.
Iifilimu zePolypropylene eziSekwe kwiBiaxially (BOPP)
I-Biaxially oriented polypropylene okanye i-BOPP1 yeyona filimu ibaluleke kakhulu yepolypropylene.Yeyona ndlela ibalaseleyo ye-cellophane, iphepha eline-wax, kunye nefoyile ye-aluminium.I-orientation inyusa amandla okuqina kunye nokuqina, yehlisa ubude (kunzima ukuyolula), kwaye iphucula iipropathi ze-optical, kwaye ngandlel' ithile iphucula iipropathi zokuthintela umphunga.Ngokubanzi, i-BOPP inamandla aphezulu okuqina, imodyuli ephezulu (ukuqina), ubude obusezantsi, isithintelo segesi esingcono, kunye nenkungu ephantsi kuneCPP.
Usetyenziso
Ifilimu yePP isetyenziselwa izinto ezininzi eziqhelekileyo zokupakisha ezifana necuba, i-candy, i-snack kunye nokutya okusonga.Ingasetyenziselwa ukusonga, iilitha zeteyiphu, iidiapers kunye nokusonga okungenantsholongwane ezisetyenziswa kwizicelo zonyango.Ngenxa yokuba i-PP ineempawu zesithintelo segesi kuphela, ihlala igqunywe nezinye iipholima ezifana ne-PVDC okanye i-acrylic ephucula kakhulu iimpawu zayo zesithintelo segesi.
Ngenxa yevumba eliphantsi, ukuchasana kweekhemikhali eziphezulu kunye nokungangeni, amaninzi amabakala e-PP afanelekile ukupakisha izicelo phantsi kwemimiselo ye-FDA.
