I-Composite Flexible Packaging Materials Development Trend e-China

Phuhlisa ifilim yokupakisha ethambileyo ehambelana nokusingqongileyo.Okwangoku, ihlabathi libonwa njengelinobuhlobo nokusingqongileyoI-PETizixhobo, kwaye inokuphinda isetyenziswe kwaye isetyenziswe kwakhona.Ngenxa yokuphuculwa kwemigangatho yokuphila kwabantu, ubomi bokutya kwevenkile enkulu buya kwanda, kwaye inani le-BOPET liya kuqhubeka linyuka, kwaye liya kuba luncedo ekuhlaziyweni nasekusetyenzisweni.

UbhetyebhetyeI-membrane yokupakisha yeplastiki iphuhlisa kwicala lentsebenzo ezinikeleyo.Umzekelo, izinto ezixhathisayo eziphezulu ziba yinto yokupakisha ethambileyo yophuhliso olushushu.Ngokuqhelekileyo zisetyenziselwa izinto ze-PVDC, izinto zokupakisha inayiloni, izinto ze-EVOH, ifilimu yokugqoka i-inorganic oxide, njl.Izinto ezidityanisiweyo eziphezulu ezixhathisayo ziya kuqhubeka ukwandisa umthamo wentengiso.Kwixesha elizayo, ifilimu ephezulu yokumelana ne-high-resistance, ene-processing elula, ukuchasana okunamandla kwi-oksijini, ukusebenza komphunga wamanzi oqinileyo, kunye neenzuzo zokukrazula ubomi beshelufu, iyona nto iphambili yokupakishwa okuthambileyo kokutya kwevenkile kwikamva.I-Multi-layer composite, i-mixed, i-co-agglomeration, kunye ne-steaming technology nayo iphuhliswe ngokukhawuleza kwishishini lokupakisha elithambileyo.

Ubhetyebhetyeizinto zokupakisha ziphuhla ziye kuthi xhaxhe.Ifilimu encinci yefilimu ibhekiselele kubukhulu bezinto ezinqamlekileyo kunye nezalathi zokusebenza ezahlukeneyo zokupakisha zisenokukwazi ukuhlangabezana ngokupheleleyo neemfuno zokupakisha.Zintathu iindlela ezingundoqo ezinokwenza oku: Okokuqala, phuhlisa izinto ezintsha, sebenzisa iPEN njengezinto ezingasetyenziswanga, amandla ePET aveliswa yiPET anokongezwa ngamaxesha angama-3.5, yaye ubukhulu befilimu bunokuncitshiswa nge-1/3 kune I-BOPET, enokuthi ihlangabezane neemfuno zefilimu ye-BOPET.Okwesibini kukwenza ifilimu yokupakisha ethambileyo enezinto ezidibeneyo kunyeNano inorganic kunye nepolymer.I-Nano inorganic kunye ne-high-polymers composite materials inokuphucula ngaxeshanye amandla kunye nokuqina kwefilimu, edlala indima ebalulekileyo kwimilo encinci yokupakisha iplastiki ethambileyo.Xa kuthelekiswa nefilimu encinci eyenziwe nge-polymer ecocekileyo, amandla kunye nokuqina kwefilimu kwifilimu kwifilimu kwanda ngama-50%.Okwesithathu kukusebenzisa izinto zokupakisha ezinamanqwanqwa amaninzi ukuphucula ukusebenza okubanzi kwezinto zokupakisha ezithambileyo, ukunciphisa inani leplastiki kwipakethe ethambileyo, ukunciphisa ukungcoliseka kwendalo kunye nokugcina izixhobo.
