Feem ntau polyethylene, los sis PP, feem ntau tus mob qhab nee, cov lawm. Tiam sis raws li kuv paub, tabsis tsis yog txhua tus tsis yooj yim tshaj plaws qib kev PP khoom siv koob txhaj uas ua qhauj yuav tau ua raws nraim li nyob rau hauv lub tsev kho mob luaj li cas qib txiav txim tias qhov zoo tshaj ntawm cov ntaub ntawv. Cov khoom no yuav tsum muaj
1, choice wide uas kom tsis muaj menyuam (chav-voltage, kub, ethylene oxide, gamma duab tshav, electron nqaj).
2, transparency yav tom ntej thiab gloss.
3, superior tshuav yam tsawg kawg nkaus distortion rigidity thiab tej yam kuj.
4, kub muaj tej yam zoo kuj.
Yuav kom tau raws li cov kev tu ncua ntawm koob txhaj siv khoom tawg yooj yim.
