Ifilimu ye-polypropylene ejonge i-Biaxial (ifilimu ye-BOPP ngamafutshane) sisixhobo esihle kakhulu sokupakisha esiguquguqukayo nesicacileyo. Ifilimu ye-polypropylene ejonge i-Biaxial ineenzuzo zokuba namandla aphezulu omzimba nawoomatshini, ubunzima obulula, ukungabi natyhefu, ukumelana nokufuma, uluhlu olubanzi lokusetyenziswa kunye nokusebenza okuzinzileyo. Ngokweendlela ezahlukeneyo zokusetyenziswa, ifilimu ye-polypropylene ejonge i-Biaxial inokwahlulwa ibe yifilimu yokutywina ubushushu, ifilimu yeleyibhile, ifilimu ye-matte, ifilimu eqhelekileyo kunye nefilimu ye-capacitor.
I-Polypropylene yinto ebalulekileyo eluhlaza kwifilimu ye-polypropylene ejongeka kabini. I-Polypropylene yi-resin yokwenziwa ye-thermoplastic esebenza kakuhle kakhulu. Inezibonelelo zokuzinza okuhle, ukumelana nobushushu obuphezulu kunye nokufakelwa kombane okuhle, kwaye ifunwa kakhulu kwicandelo lokupakisha. Ngo-2021, imveliso ye-polypropylene (PP) yelizwe lam iya kufikelela kwiitoni ezingama-29.143 ezigidi, ukunyuka konyaka nonyaka kwe-10.2%. Ukuxhamla kubonelelo olwaneleyo lwezinto eziluhlaza, ishishini lefilimu ye-polypropylene ejongeka kabini kwilizwe lam liye lakhula ngokukhawuleza, kwaye imveliso yalo iqhubekile nokukhula. Ngokwedatha evela kwi-National Bureau of Statistics, imveliso yefilimu ye-polypropylene ejongeka kabini kwilizwe lam iya kufikelela kwiitoni ezingama-4.076 ezigidi ngo-2021, ukunyuka konyaka nonyaka kwe-8.7%.
Iindlela zokuvelisa ifilimu ye-polypropylene ejolise kwicala eli-2 ziquka indlela yefilimu yetyhubhu kunye nendlela yefilimu ethe tyaba. Ngenxa yomgangatho ongalinganiyo kunye nokusebenza kakuhle kweemveliso eziveliswa yindlela ye-tubular membrane, ziye zasuswa kancinci kancinci ziinkampani ezinkulu. Indlela yefilimu ethe tyaba inokwahlulwahlulwa ibe yindlela yokusolula ityhubhu ngaxeshanye kunye nendlela yokusolula ityhubhu ngenyathelo. Inkqubo yokusolula ityhubhu ngenyathelo yile ilandelayo: izinto eziluhlaza→ukukhupha→ukusika→ukuphosa→ukusolula i-longitudinal→ukucheba umphetho→unyango lwe-corona→ukujija→ukuqengqeleka kwefilimu enkulu→ukuguga→ukusikeka→imveliso egqityiweyo. Okwangoku, indlela yokusolula ityhubhu kancinci kancinci iyamkelwa ziinkampani ezininzi ngenxa yeengenelo zayo zobuchwepheshe obuvuthiweyo, ukusebenza kakuhle kwemveliso, kunye nokufaneleka kwemveliso enkulu.
Ifilimu yepolypropylene ejonge i-Biaxial isetyenziswa kakhulu kwizixhobo zokupakisha ezifana neempahla, ukutya, amayeza, ukushicilela, icuba kunye notywala. Okwangoku, ifilimu yepolypropylene ejonge i-biaxial iye yathatha indawo yeefilimu zokupakisha eziqhelekileyo ezifana ne-polyethylene (PE), i-polypropylene (PP), kunye ne-polyvinyl chloride (PVC). Ilizwe lam lilizwe lesibini ngobukhulu emhlabeni, kwaye imfuno yokupakisha iyaqhubeka nokukhula. Ngokwezibalo ezivela kwi-China Packaging Federation, ingeniso eqokelelweyo yamashishini angaphezu kobukhulu obumiselweyo kushishino lokupakisha lwelizwe lam iya kufikelela kwi-1,204.18 yeebhiliyoni zeerandi ngo-2021, ukunyuka konyaka nge-16.4%. Ngophuhliso olukhawulezileyo lweshishini lokupakisha lelizwe lam, ifilimu yepolypropylene ejonge i-biaxial iya kuba namathuba emarike ebanzi njengezixhobo zokupakisha ezibalulekileyo.
Abahlalutyi bemizi-mveliso baseXisijie bathi ukuxhamla kubonelelo olwaneleyo lwezinto eziluhlaza kunye nokuvuthwa okuphezulu kobuchwepheshe bemveliso, amandla ophuhliso lweshishini lefilimu ye-polypropylene yelizwe lam ejolise kwicala elinye likhulu kakhulu. Uphuhliso olukhawulezileyo lweshishini lokupakisha luya kuqhuba ukwanda ngakumbi kwemarike yefilimu ye-polypropylene yelizwe lam ejolise kwicala elinye. Ngokukhula kwengcamango yokusetyenziswa okuluhlaza, abathengi baya kuphucula ngakumbi iimfuno zomgangatho wezinto zokupakisha, kwaye ifilimu ye-polypropylene egcina amandla kwaye enobuhlobo nokusingqongileyo iya kuba yeyona nto iphambili kwimarike.
