Hunhu hunoshanda hwezvinhu zvekurongedza mafirimu hunotungamira zvakananga kugadzirwa kwezvinhu zvekurongedza zvinochinjika zvine musanganiswa. Zvinotevera ipfupiso yehunhu hunoshanda hwezvinhu zvakawanda zvinoshandiswa pakurongedza.
1. Zvinhu zvinoshandiswa pakurongedza: PE firimu
Zvinhu zvePE zvinovharika nekupisa zvakashanduka kubva pamafirimu anoputika nechikamu chimwe chete kuenda kumafirimu anobudiswa nechikamu chimwe chete, kuitira kuti mafomula emukati, pakati nekunze anogona kugadzirwa zvakasiyana. Dhizaini yefomula yekusanganisa yemhando dzakasiyana dzema polyethylene resins inogona kugadzira tembiricha dzakasiyana dzekuvhara, tembiricha dzakasiyana dzekuvhara kupisa, hunhu hwakasiyana hwekudzivirira kuvhara,hsimba rekunamatira, mhedzisiro inodzivirira static, nezvimwewo, kuti isangane nezvinodiwa zvekurongedza zvigadzirwa uye zvinhu zvePE film zvine hunhu hwakasiyana hwekushanda.
Mumakore achangopfuura, mafirimu epolyethylene (BOPE) ane ma "biaxially oriented" akagadzirwawo, ayo anovandudza simba rekudhonza kwemafirimu epolyethylene uye ane simba rakawanda rekuvhara kupisa.
2. Zvinhu zveCPP Firimu
Zvinhu zveCPP zvinowanzo shandiswa muBOPP/CPP chimiro ichi chemwenje chinodzivirira hunyoro, asi magadzirirwo akasiyana eCPP resin anogonawo kugadzirwa nezvinhu zvakasiyana-siyana zvinoshanda zvefirimu, zvakaita sekudzivirira kupisa kwakaderera, kudzivirira kubika pakupisa kwakanyanya, kupisa kwakaderera, simba rakanyanya kubhoorwa, kudzivirira ngura, nezvimwe zvinhu zvinoshanda zvezvinhu zvinovhara kupisa.
RMumakore achangopfuura, indasitiri iyi yakagadzirawo firimu reCPP matte, zvichiwedzera mhedzisiro yekuratidzwa kwemifananidzo yemabhegi efirimu eCPP ane layer imwe chete.
3. Zvinhu zveBOPP zvemafirimu
Firimu rekugadzira zvinhu zvine mwenje rinoshandiswa zvakanyanya muBOPP light film uye BOPP matte film, kunewo BOPP heat sealing film (single-sided kana double-sided heat sealing), BOPP pearl film.
BOPP ine simba guru rekusunga (rakakodzera kudhindwa nemavara akawanda), hunhu hwakanaka hwekudzivirira mhute yemvura, inoshandiswa zvakanyanya pakurongedza chiedza chinodzivirira hunyoro kumeso kwezvinhu zvakadhindwa.
Firimu reBOPP rakapfava rine mhedzisiro yekushongedza yakapfava yakafanana nepepa. Firimu reBOPP rinovhara kupisa rinogona kushandiswa sezvinhu zvekurongedza zvine jira rimwe chete, sekuputira mukati meswiti. Firimu reBOPP remaparera rinonyanya kushandiswa pakuisa ice-cream packaging heat sealing layer, rinogona kuchengetedza kudhinda kweinki chena, ine density shoma, 2 kusvika 3N/15mm sealing simba kuitira kuti bhegi rive nyore kuvhura kuti ribudise zviri mukati.
Pamusoro pezvo, zvakaita seBOPP anti-fog film, holographic OPP laser film, PP synthetic paper, biodegradable BOPP film uye mamwe mafirimu anoshanda eBOPP akatevedzana akakurudzirwa uye anoshandiswa mune zvakasiyana-siyana.
4. Zvinhu zvinoshandiswa pakurongedza zvinowanzo shandiswa: PET firimu zvinhu
Firimu remwenje re12MICRONS PET rinoshandiswa zvakanyanya mukupakira kwakabatana, simba remuchina wezvigadzirwa zvaro zvekupakira zvakanamirwa rakakwirira kupfuura zvigadzirwa zveBOPP zvakabatana zvine layer (zvakaderera zvishoma pane zvigadzirwa zveBOPA zvakabatana zvine layer), uye kugona kweoxygen barrier kweBOPP/PE (CPP) composite film kuderedza ka20 kusvika ku30.
Kudzivirira kupisa kwezvinhu zvePET kwakanaka kwazvo, uye kunogona kuitwa kuti mabhegi akanaka anyatsotsvedza. Firimu rePET rinotsvedza kupisa, firimu rePET rinotsvedza kupisa, firimu rePET rinotsvedza kupisa, firimu rePET rinotsvedza kupisa, firimu rePET rinotsvedza rine mitsetse yakawanda, firimu rePET rinotsvedza, firimu rePET rinotsvedza rine mitsetse yakatsetseka nezvimwe zvigadzirwa zvinoshanda zvinoshandiswawo.
5. Zvinhu zvakajairika zvekurongedza: firimu renylon
Firimu renylon rakanangana nepakati pemaaxial rinoshandiswa zvakanyanya mumabhegi evacuum, ekufashaira uye ekuputira mweya nekuda kwesimba rayo guru, kuramba kubhoorwa kwakanyanya, kuramba kupisa kwakanyanya uye oxygen iri nani.
Mapochi mazhinji ane laminated anorema kupfuura 1.7kg anoshandisawo chimiro cheBOPA//PE kuti arambe kudonha zvakanaka.
Firimu renylon rakaumbwa, rinoshandiswa zvakanyanya muJapan pakurongedza chikafu chakaomeswa nechando, iro rinodzivirira kupisa kwakaderera, richideredza kupwanyika kwebhegi panguva yekuchengetwa nekutakura.
6. Zvinhu Zvakajairika Zvekurongedza: Aluminium coating Metalized Film
Kugadzira aluminiyamu yemuchina wevacuum (senge PET, BOPP, CPP, PE, PVC, nezvimwewo) ndiko kuumbwa kwechikamu chearuminiyamu yakakora, nokudaro zvichiwedzera zvakanyanya firimu pamusoro pemvura, okisijeni, chiedza chinovhara simba, ndiyo inonyanya kushandiswa muzvinhu zvinosanganiswa zvinochinjika zveVMPET, VMCPP.
VMPET yekuisa laminating ine mativi matatu, VMCPP yekuisa laminating ine mativi maviri.
Chimiro cheOPP//VMPET//PE chave kushandiswa zvakanyanya mumiriwo inosvinwa, zvigadzirwa zvesprouts zviri mupakeji yekufashaira yevacuum. Chimiro chePE chave kushandiswa zvakanyanya mukubikisa miriwo, zvigadzirwa zvesprouts zviri mupakeji yekufashaira yevacuum, kuitira kukunda zvikanganiso zvezvigadzirwa zvakajairika zvealuminum, aluminium layer iri nyore kutamisa, usaramba zvikanganiso zvekufashaira, kugadzirwa kwezvigadzirwa zveVMPET zvine rudzi rwekuputira pasi, simba rekudonha risati rafashaira rinodarika 1.5N/15mm uye mushure mekufashaira, uye aluminium layer haisi kuita serinotamisa, zvinovandudza mashandiro ese echipingamupinyi chebhegi.
7. Zvinhu zvakajairika zvekurongedza: Aluminium foil
Foiri yealuminium yekurongedza inochinjika inowanzo kuve 6.5μm kana 9μUkobvu hwe12microns, aluminium foil inyaya yekudzivirira mvura, kubvumidzwa kweokisijeni, kubvumidzwa kwechiedza "0", asi kutaura chokwadi kune maburi ari mualuminium foil uye kupesana nekupeta maburi, kune akawanda maitiro ekudzivirira kuputirwa kwezvipingamupinyi hazvina kunaka. Chinhu chikuru chekushandisa aluminium foil kudzivirira maburi panguva yekugadzirisa, kuputirwa uye kutakurwa, nokudaro zvichideredza kugona kwekudzivirira chaiko. Mumakore achangopfuura, kune katsika kekuti zvinhu zvealuminium foil zvinotsiviwa nezvinhu zvepurasitiki zvinodhura zvakanyanya munzvimbo dzazvo dzechinyakare dzekushandisa.
8. Zvinhu zvinoshandiswa pakurongedza zvinowanzo shandiswa: mafirimu akafukidzwa nemadziro ane madziro akareba
Zvikuru firimu rakafukidzwa nePVDC (firimu reK coating), firimu rakafukidzwa nePVA (firimu reA coating).
PVDC ine kudzivirirwa kwakanaka kweokisijeni uye hunyoro, uye ine kujeka kwakanaka, firimu rePVDC rakaputirwa rinoshandiswa mufirimu repasi rinonyanya kushandiswa BOPP, BOPET, BOPA, CPP, nezvimwewo, asiwo inogona kuva PE, PVC, cellophane nemamwe mafirimu, mupakeji inochinjika yakawanda mufirimu reKOPP, KPET, KPA rinoshandiswa zvakanyanya.
9. Zvinhu Zvakajairika Zvekurongedza: Mafirimu Anodzivirira Akawanda Akabatanidzwa
Co-extrusion ipurasitiki mbiri kana kupfuura dzakasiyana, kuburikidza ne extruders mbiri kana kupfuura, zvichiteerana, kuitira kuti mapurasitiki akasiyana-siyana anyungudike uye apfeke purasitiki kuti pave nemusoro wekufa, kugadzirira mafirimu ecomposite enzira yekuumba. Mafirimu ecomposite e-extruded barrier anowanzo gadzirwa kubva musanganiswa wepurasitiki dzebarrier, mapurasitiki epolyolefin uye maresini anonamira emhando nhatu huru dzezvinhu, maresini ebarrier anonyanya kuve PA, EVOH, PVDC, nezvimwewo.
Zviri pamusoro apa zvinhu zvakajairika zvekurongedza, kutaura zvazviri, zvirinani kushandisa oxide vapor coating, PVC, PS, PEN, bepa, nezvimwewo, uye resin imwechete zvichienderana nenzira dzakasiyana dzekugadzirisa, mafomula akasiyana anogona kugadzirwa nekushandurwa kwehunhu hwakasiyana hwebasa refirimu. Kuisa lamination yemafirimu akasiyana anoshanda, kuburikidza ne dry lamination, solvent-free lamination, extrusion lamination nedzimwe tekinoroji dzakasanganiswa kugadzira zvinhu zvinoshanda zvakasanganiswa zvinochinjika zvekurongedza kuti zvizadzise zvinodiwa zvemarudzi akasiyana.zvigadzirwakurongedza.
