Yintoni iifilimu zePP?

IIPROPATI

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 zePPzilufanelekele kakuhle uluhlu olubanzi lwemizi-mveliso, abathengi, kunye nezicelo zeemoto.

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 kwiipakethe 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.

IZICELO

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 zothintelo lwerhasi kuphela, ihlala igqunywe nezinye iipholima ezifana ne-PVDC okanye i-acrylic ephucula kakhulu iipropati zesithintelo segesi.

Ngenxa yevumba eliphantsi, ukuchasana kweekhemikhali eziphezulu kunye nokungangeni, amaninzi amabakala e-PP afanelekile ukupakisha izicelo phantsi kwemimiselo ye-FDA.
