Multilayer coextrusion filimi
E le ho eketsa nako ea bophelo ba lijo, meriana le lisebelisoa tse ling, lisebelisoa tse ngata tsa ho paka lijo le lithethefatsi hona joale li sebelisa lifilimi tse kopantsoeng tse nang le likarolo tse ngata tsa co-extrusion.Hona joale, ho na le likarolo tse peli, tse tharo, tse hlano, tse supileng, tse robong, esita le tse leshome le motso o mong tsa lisebelisoa tsa ho paka.Filimi ea li-multi-layer co-extrusion ke filimi e hlahisang mefuta e fapaneng ea lisebelisoa tsa polasetiki ho tloha ho lefu le le leng ka nako e le 'ngoe ka litsela tse ngata, tse ka fanang ka papali ho melemo ea thepa e fapaneng.
Multi-layer co-extruded composite filimi haholo-holo e entsoe ka polyolefin.Hona joale, mehaho e sebelisoang haholo e kenyelletsa: polyethylene / polyethylene, polyethylene / vinyl acetate copolymer / polypropylene, LDPE / adhesive layer / EVOH / adhesive layer / LDPE, LDPE / adhesive layer / EVOH / EVOH / adhesive layer / LDPE.Botenya ba lera ka 'ngoe bo ka fetoloa ka mokhoa oa extrusion.Ka ho fetola botenya ba mokoallo oa mokoallo le tšebeliso ea lisebelisoa tse sa tšoaneng tsa mokoallo, filimi e nang le thepa e fapaneng ea thibelo e ka etsoa ka mokhoa o bonolo, 'me thepa ea ho tiisa mocheso e ka boela ea fetoloa ka mokhoa o bonolo le ho abeloa ho finyella litlhoko tsa liphutheloana tse fapaneng.Motsoako ona oa multilayer le multifunction co-extrusion ke tataiso e kholo ea nts'etsopele ea ho paka thepa ea lifilimi nakong e tlang.
