Izvo zvinoshanda zvimiro zvekurongedza zvemufirimu zvinhu zvinofambisa zvakananga kusimudzira kwekushanda kwecomposite inochinjika yekurongedza zvinhu. Iyi inotevera sumo pfupi kune inoshanda zvivakwa zvezvizhinji zvinowanzoshandiswa pakurongedza zvinhu.
1. Inowanzoshandiswa kurongedza zvinhu: PE firimu
Heat-sealable PE zvinhu zvakashanduka kubva kune imwe-layer inoputika mafirimu kune akawanda-layer co-extruded mafirimu, kuitira kuti mafomula emukati, epakati uye ekunze akaturikidzana anogona kugadzirwa zvakasiyana. Iyo yekusanganisa fomula dhizaini yemhando dzakasiyana dzepolyethylene resins inogona kuburitsa tembiricha yekuisa chisimbiso, dzakasiyana kupisa-kuvharisa tembiricha mazinga, akasiyana e-anti-sealing kusvibiswa zvivakwa,hot anonamira masimba, anti-static mhedzisiro, nezvimwewo, kusangana nechaiyo chigadzirwa chekurongedza zvinodiwa uye PE firimu zvinhu zvine akasiyana anoshanda zvivakwa.
Mumakore achangopfuura, biaxially oriented polyethylene (BOPE) mafirimu akagadzirwawo, ayo anovandudza kusimba kwekusimba kwemafirimu epolyethylene uye ane yakanyanya kupisa-kuvharisa simba.
2. CPP Film Material
CPP zvinhu zvinowanzo shandiswa muBOPP / CPP iyi mwando-inoratidza chiedza kurongedza chimiro, asi akasiyana CPP resin maumbirwo anogona zvakare kugadzirwa akasiyana anoshanda emufirimu, akadai sekuvandudzwa kwekudzikira kwekudzivirira, kuramba kupisa kwepamusoro-tembiricha, kudzika. tembiricha yekuisa chisimbiso, simba rakanyanya kupinza, corrosion resistance, uye zvimwe zvinoshanda zvezvinhu zvinovhara kupisa.
Rmakore achangopfuura, indasitiri yakagadzirawo CPP matte firimu, ichiwedzera iyo yekuona mhedzisiro yeimwe-layer CPP mafirimu emabhegi.
3. BOPP firimu zvinhu
Chiedza chekurongedza composite firimu rinonyanya kushandiswa rakajairwa BOPP mwenje firimu uye BOPP matte firimu, kune zvakare BOPP kupisa yekuisa chisimbiso firimu (rimwe divi kana kaviri-kumativi kupisa sealing), BOPP pearl firimu.
BOPP inoratidzirwa nehupamhi hwekusimba kwesimba (inokodzera kuwanda-mavara overprinting), yakanakisa mvura vapor barriers zvivakwa, inoshandiswa zvakanyanya mukunyoro-inodzivirira chiedza kurongedza kwechiso chezvakadhindwa.
BOPP matte firimu ine matte yekushongedza maitiro akafanana nebepa. BOPP inopisa yekuisa chisimbiso firimu inogona kushandiswa seimwe-layer yekurongedza zvinhu, senge yekuputira yemukati yekurongedza yepipi ne. BOPP pearl firimu rinonyanya kushandiswa kweaizi-kirimu kurongedza kupisa sealing layer zvinhu, inogona kuchengetedza inki chena kudhinda, yakaderera density, 2 kusvika 3N / 15mm chisimbiso simba kuitira kuti bhegi rive nyore kuvhura kuti utore zviri mukati.
Pamusoro pezvo, senge BOPP anti-fog firimu, holographic OPP laser firimu, PP synthetic bepa, biodegradable BOPP firimu uye mamwe maBOPP akateedzana emafirimu anoshanda akave akakurumbira uye akaiswa mune yakatarwa siyana.
4. Inowanzoshandiswa kurongedza zvinhu: PET firimu zvinhu
Zvakajairwa 12MICRONS PET mwenje firimu rinoshandiswa zvakanyanya mucomposite inochinjika kurongedza, iyo mechanic simba reiyo laminated packaging zvigadzirwa yakakwira zvakanyanya kupfuura iyo BOPP mbiri-layer composite zvigadzirwa (zvishoma zvishoma pane iyo BOPA yakapetwa-layer composite zvigadzirwa), uye iyo okisijeni barriers kugona. yeBOPP/PE (CPP) inoumbwa firimu kuderedza makumi maviri kusvika makumi matatu nguva.
Kupisa kwekupisa kwePET zvinhu kwakanaka kwazvo, uye kunogona kugadzirwa kune flatness yemabhegi akanaka. iyo PET inopisa-inopisa firimu, matte PET PET inopisa-inopisa firimu, matte PET firimu, yakakwirira-barrier polyester firimu, PET twist firimu, mutsara wemisodzi PET firimu uye zvimwe zvinoshanda zvigadzirwa zvinoshandiswa zvakare.
5. Common packaging material : naironi firimu
Biaxially oriented nylon firimu rinoshandiswa zvakanyanya muvacuum, kufashaira uye mabhegi ekupfungaira nekuda kwesimba rayo repamusoro, kukwirira kwepinji kuramba, tembiricha yekudzivirira uye zvirinani zvipingamupinyi zveokisijeni.
Mazhinji ehombe-akakura-aminated pouches pamusoro pe 1.7kg anoshandisawo BOPA//PE chimiro kune yakanaka kudonha kuramba.
Kanda firimu renylon, rinoshandiswa zvakanyanya muJapan kurongedza chikafu chakaomeswa, icho chine yakanaka yakadzika tembiricha kuramba, ichidzikisa chiyero chekuputsika kwebhegi panguva yakadzika tembiricha yekuchengetedza uye yekufambisa.
6. Common Packaging Material : Aluminium coating Metalized Film
Vacuum aluminizing iri mufirimu (yakadai sePET, BOPP, CPP, PE, PVC, nezvimwewo) pamusoro pekugadzirwa kwedense aluminium layer, nokudaro ichiwedzera zvakanyanya firimu pamhute yemvura, okisijeni, chiedza chinodzivisa kukwanisa. , iyo inonyanya kushandiswa mune inosanganiswa inochinjika yekurongedza VMPET, VMCPP zvinhu.
VMPET kune matatu-layer laminating, VMCPP kune maviri-layer laminating.
OPP//VMPET// PE chimiro parizvino chave kushandiswa mushishi miriwo, inomera zvigadzirwa mune vacuum inofashaira yekurongedza. Chimiro chePE ikozvino chave chave kushandiswa kusvina miriwo, inomera zvigadzirwa muvacuum inofashaira yekurongedza, kuti ikunde zvikanganiso zvezvakajairwa zvigadzirwa zvealuminium, aluminium layer iri nyore kutama, usarambe kukanganisa kwekubikira, kuvandudzwa kweVMPET zvigadzirwa zvine iyo yepasi yekuputira mhando, isati yasvika uye mushure mekubikira kwesimba rekusvuura rinopfuura 1.5N/15mm, uye aluminium layer haioneki. kutama, simbisa iyo yese inovharira kuita kwebhegi.
7. Zvakajairwa kurongedza zvinhu: Aluminium foil
Aluminium foil yekurongedza inochinjika inowanzo 6.5μm kana 9μm 12microns ukobvu, aruminiyamu foil inotepfenyura yakakwira chipingamupinyi zvinhu, kupenya kwemvura, kupenya kweokisijeni, kupenya kwechiedza ndi "0", asi kutaura zvazviri kune mapinho mualuminium foil uye kupeta kushomeka kwepinhole kuramba, kune akati wandei ekuvharisa. mhedzisiro haina kunaka. Kiyi yekushandiswa kwealuminium foil ndeyekudzivirira pinholes panguva yekugadziriswa, kurongedza uye kutakura, nekudaro kudzikisa iyo chaiyo yekuvharira kugona. Mumakore achangopfuura, pane katsika kekuti aruminiyamu foil zvinhu zvitsiviwa nezvimwe zvehupfumi zvekurongedza munzvimbo dzavo dzechinyakare dzekushandisa.
8. Inowanzo shandiswa kurongedza zvinhu: yakavharidzirwa yakakwirira-barriers mafirimu
Kunyanya PVDC yakavharwa firimu (K coating film), PVA coated film (A coating film).
PVDC ine yakanakisa mhinganidzo yeokisijeni uye inodzivirira hunyoro, uye ine kujeka kwakanyanya, yakavharwa PVDC firimu rinoshandiswa mubhesi firimu rinonyanya BOPP, BOPET, BOPA, CPP, nezvimwewo, asi zvakare inogona kuve PE, PVC, cellophane nemamwe mafirimu, mune composite inochinjika kurongedza mune inonyanya kushandiswa KOPP, KPET, KPA firimu.
9. Common Packaging Materials: Co-extruded High Barrier Films
Co-extrusion mapurasitiki maviri kana anopfuura akasiyana, kuburikidza maviri kana anopfuura maviri eextruder, zvichiteerana, kuitira kuti zvakasiyana-siyana zvepurasitiki zvinonyunguduka uye plasticizing kune maviri ekufa musoro, kugadzirirwa kwemafirimu akaumbwa emhando yekuumba. Co-extruded barrier composite mafirimu anowanzo gadzirwa kubva musanganiswa wezvipingamupinyi mapurasitiki, polyolefin mapurasitiki uye anonamira resins emhando mitatu mikuru yezvinhu, barriers resins inonyanya PA, EVOH, PVDC, nezvimwe.
Izvo zviri pamusoro zvinongojairika kurongedza zvinhu, kutaura zvazviri, kanenge kushandiswa kwe oxide vapor coating, PVC, PS, PEN, bepa, nezvimwewo, uye yakafanana resin zvinoenderana nenzira dzakasiyana dzekugadzirisa, maumbirwo akasiyana anogona kugadzirwa nekugadziriswa kwakasiyana. zvinoshanda zvinhu zvemufirimu zvinhu. Lamination yemafirimu akasiyana anoshanda, kuburikidza neyakaoma lamination, solvent-isina lamination, extrusion lamination uye imwe composite tekinoroji kugadzira inoshanda composite inochinjika yekurongedza zvinhu kusangana nezvinodiwa zvakasiyana.zvigadzirwakurongedza.
