I-CPP yifilimu ye-polypropylene (PP) eveliswa yi-cast extrusion kwishishini leplastiki. Olu hlobo lwefilimu lwahlukile kwifilimu ye-BOPP (ibidirectional polypropylene) kwaye yifilimu engajoliswanga. Ngokuthe ngqo, iifilimu ze-CPP zinolwalathiso oluthile kwicala elide (MD), ikakhulu ngenxa yohlobo lwenkqubo. Ngokuphola ngokukhawuleza kwiirola ezibandayo, ukucaca okugqwesileyo kunye nokugqitywa kwakheka kwifilimu.
Iimpawu eziphambili zefilimu yeCpp:
ixabiso eliphantsi kunye nemveliso ephezulu xa kuthelekiswa nezinye iifilimu ezifana ne-LLDPE, i-LDPE, i-HDPE, i-PET, i-PVC; Ukuqina okuphezulu kunefilimu ye-PE; Umqobo ogqwesileyo wokufuma kunye nevumba; Imisebenzi emininzi, ingasetyenziswa njengefilimu esisiseko edibeneyo; Ukwenziwa kwesinyithi kunokwenzeka; Njengokupakisha ukutya kunye neempahla kunye nokupakishwa kwangaphandle, inomboniso ogqwesileyo kwaye inokwenza imveliso ibonakale ngokucacileyo phantsi kwephakheji
Okwangoku, kukho uluhlu olubanzi lweemveliso zeefilimu ze-CPP. Kuphela xa amashishini eqhubeka nokuphuhlisa iimveliso ezintsha, evula amasimi amatsha okusetyenziswa, ephucula amandla okulawula umgangatho, kwaye eqonda ngokwenene ukwenziwa kwemveliso ngokwezifiso kunye nokwahlulwahlulwa, apho anokuthi angoyiswa khona kwimarike.
Ifilimu yePP yi-polypropylene ephosiweyo, ekwaziwa ngokuba yifilimu ye-polypropylene enganwetywanga, enokwahlulwa ibe yifilimu ye-CPP (GCPP) ngokubanzi, ifilimu ye-aluminized CPP (Metalize CPP, MCPP) kunye nefilimu ye-Retort CPP (RCPP) ngokweendlela ezahlukeneyo zokusetyenziswa.
I-CPP yifilimu enganwebekiyo, engajoliswanga ecaleni, ephuma ngokuthe tyaba eveliswa yi-melt cast quenching. Xa ithelekiswa nefilimu evuthuziweyo, ibonakaliswa ngesantya sokuvelisa esikhawulezayo, imveliso ephezulu, kunye nokucaca okuhle kwefilimu, ukukhazimla, kunye nokufana kobukhulu. Kwangaxeshanye, kuba yifilimu ephuma ngokuthe tyaba, iinkqubo zokulandelela ezifana nokuprinta kunye nokulaminetha zilula kakhulu, ngoko ke zisetyenziswa kakhulu ekupakisheni amalaphu, iintyatyambo, ukutya kunye nezinto ezifunekayo zemihla ngemihla.
