Ifilimu yepolypropylene ejolise kwi-Biaxially (ifilimu yeBOPP emfutshane) yeyona nto ibalaseleyo ekuhleni yokupakisha izinto eziguquguqukayo.Ifilimu ye-polypropylene ejoliswe kwi-Biaxially ineenzuzo zamandla aphezulu omzimba kunye noomatshini, ubunzima bokukhanya, ukungabi nabutyhefu, ukuxhathisa umswakama, uluhlu olubanzi lwesicelo kunye nokusebenza okuzinzile.Ngokokusetyenziswa okwahlukileyo, ifilimu ye-polypropylene ejoliswe kwi-biaxially inokwahlulwa ibe yifilimu yokutywina ubushushu, ifilimu yeleyibhile, ifilimu ye-matte, ifilimu eqhelekileyo kunye nefilimu ye-capacitor.
I-Polypropylene yimathiriyeli ekrwada ebalulekileyo yefilim yepolypropylene ene-biaxially oriented.I-Polypropylene yiresin eyenziwe ye-thermoplastic esebenza kakuhle.Ineenzuzo zokuzinza komgangatho olungileyo, ukumelana nobushushu obuphezulu kunye nokugqunyelelwa kombane okulungileyo, kwaye ikwimfuno enkulu kwindawo yokupakisha.Ngo-2021, imveliso yelizwe lam i-polypropylene (PP) iya kufikelela kwi-29.143 yezigidi zeetoni, ukunyuka konyaka-ngonyaka kwe-10.2%.Ukuzuza kubonelelo olwaneleyo lwemathiriyeli ekrwada, imboni yefilimu yelizwe lam ye-biaxially oriented polypropylene iphuhliswe ngokukhawuleza, kwaye imveliso yayo iqhubekile nokukhula.Ngokutsho kwedatha evela kwi-National Bureau of Statistics, imveliso yefilimu ye-biaxially oriented polypropylene iya kufikelela kwi-4.076 yezigidi zeetoni ngo-2021, ukunyuka konyaka-ngonyaka kwe-8.7%.
Iindlela zokuvelisa ifilimu ye-polypropylene ejoliswe kwi-biaxially ibandakanya indlela yefilimu ye-tubular kunye ne-flat film method.Ngenxa yomgangatho ongalinganiyo kunye nokusebenza okuphantsi kweemveliso eziveliswa yindlela ye-membrane ye-tubular, ziye zapheliswa ngokuthe ngcembe ngamashishini amakhulu.Indlela yefilimu ye-flat inokwahlulwa ibe yindlela yokwelula i-biaxial ngexesha elinye kunye ne-stepwise biaxial stretching method.Inkqubo yokwalula inyathelo nenyathelo ilandelayo: imathiriyeli ekrwada→ukukhupha→ukusasa→ukwaluka okude→ukucheba komphetho→unyango lwecorona→ujiko→ifilim enkulu→ukuguga→ukusika→imveliso egqityiweyo.Okwangoku, indlela yokwelula i-biaxial ngokuthe ngcembe yamkelwa ngamashishini amaninzi ngenxa yeenzuzo zayo zobuchwepheshe obuvuthiweyo, ukusebenza kakuhle kwemveliso, kunye nokufaneleka kwemveliso ngobuninzi.
Ifilimu ye-polypropylene ejoliswe kwi-Biaxially isetyenziswa ngokubanzi kwizinto zokupakisha ezifana nempahla, ukutya, amayeza, ukushicilela, icuba kunye notywala.Okwangoku, ifilimu ye-polypropylene ejolise kwi-biaxially ithathe indawo yeefilimu eziqhelekileyo zokupakisha ezifana ne-polyethylene (PE), i-polypropylene (PP), kunye ne-polyvinyl chloride (PVC).ilizwe lam lilizwe lesibini ngobukhulu emhlabeni, kwaye imfuno yokupakishwa iyaqhubeka ikhula.Ngokwezibalo ezivela kwi-China Packaging Federation, ingeniso eyongezelekayo yamashishini angaphezu kobukhulu obumiselweyo kushishino lokupakisha lwelizwe lam iya kufikelela kwi-1,204.18 yeebhiliyoni zeeyuan ngo-2021, ukonyuka konyaka nge-16.4%.Ngophuhliso olukhawulezayo lweshishini lokupakisha lelizwe lam, ifilimu ye-polypropylene esekelwe kwi-biaxially iya kuba nethemba elibanzi lemarike njengento ebalulekileyo yokupakisha.
Abahlalutyi boShishino abavela kwiXinsijie bathi ukuxhamla kubonelelo olwaneleyo lwemathiriyeli ekrwada kunye nokuvuthwa okuphezulu kobugcisa bemveliso, amandla ophuhliso oshishino lwefilim yelizwe lam ajolise kwi-biaxially makhulu.Uphuhliso olukhawulezayo lweshishini lokupakisha luya kuqhuba ukwanda ngakumbi kwemarike yebhanyabhanya yepolypropylene yelizwe lam.Ngokunzulu kombono wokusetyenziswa okuluhlaza, abathengi baya kuphucula ngakumbi iimfuno zomgangatho wezinto zokupakisha, kunye nefilimu egcina amandla kunye nendalo ehambelana ne-biaxially oriented polypropylene iya kuba yeyona nto iphambili kwintengiso.
