4, Okpomọkụ akara BOPP ihe nkiri
Ihe nkiri mkpuchi ọkụ nwere akụkụ abụọ:
Nke a film bụ ABC Ọdịdị, A na C n'akụkụ maka okpomọkụ akara oyi akwa. A na-ejikarị eme ihe dị ka ihe nkwakọba ihe maka nri, akwa akwa, ngwaahịa ọdịyo na vidiyo, wdg.
Ihe nkiri mkpuchi okpomọkụ nwere otu akụkụ:
Ụdị ihe nkiri a bụ nhazi ABB, yana A oyi akwa dị ka mkpuchi mkpuchi okpomọkụ. Mgbe e bipụtachara usoro n'akụkụ B, a na-eji PE, BOPP na foil aluminom mee akpa, nke a na-eji dị ka ihe nkwakọ ngwaahịa dị elu maka nri, ihe ọṅụṅụ, tii, wdg.
5, Ihe nkiri CPP na-egbu oge
Ihe nkiri nkedo CPP polypropylene bụ ihe nkiri polypropylene na-abụghị nke na-agbatị, na-abụghị ntụzi aka.
A na-eji ihe nkiri CPP mara ọkwa dị elu, ezigbo flatness, ezigbo nkwụsị okpomọkụ dị elu, mgbanwe ụfọdụ na-enweghị nkwụsịtụ, ezigbo ihe mkpuchi okpomọkụ. Homopolymer CPP nwere warara dị warara nke okpomọkụ na-ekpuchi ọkụ na oke nhịkọ, na-eme ka ọ dị mma maka ojiji dị ka ihe nkiri nkwakọ ngwaahịa otu oyi akwa.
Co-polymer CPP nwere arụmọrụ kwesịrị ekwesị ma dị mma dị ka oyi akwa dị n'ime nke ihe nkiri mejupụtara. Ka ọ dị ugbu a, ndị n'ozuzu na-ejikọta CPP, nwere ike iji ụdị polypropylene dị iche iche nke ngwakọta, na-eme ka arụmọrụ CPP dịkwuo oke.
6, ihe nkiri IPP gbawara agbawa
A na-emepụta ihe nkiri IPP na-agbapụtakarị site na usoro ịkụda ala, PP na-apụ apụ ma na-afụ ya na mgbanaka anwụ ọnụ, ozugbo ikuku ikuku jụrụ oyi, nke mmiri na-eme ka ọ dị jụụ, nke a mịrị amị na akpọrepu, ngwaahịa emechara bụ ihe nkiri cylinder, nke nwekwara ike ịkpụ ka ọ bụrụ ihe nkiri mpempe akwụkwọ. Blown IPP nwere ezi nghọta, ezi rigidity na mfe akpa ime, ma ya ọkpụrụkpụ uniformity bụ ogbenye na film flatness adịghị mma.
