Flexible packaging imhando yekurongedza yakagadzirwa kubva kune zvinochinjika zvinhu zvinosanganisa zvakanakira epurasitiki, firimu, bepa uye aluminium foil, ine maficha akadai seakareruka uye kutakurika, kuramba kwakanaka kune ekunze masimba, uye kusimba. Zvimwe zvezvinhu zvinoshandiswa mukurongedza zvinochinjika zvinonyanya firimu repurasitiki, aluminium foil, bio-based materials, coated materials, biodegradable packaging uye zvichingodaro.

Flexible packaging product applications zvinosanganisira: mabhegi, kuputira-kutenderedza firimu, mabhegi egirosari, kuputira, kutambanudza firimu uye kurongedza kwemvura yemabhodhoro. Hunhu hwakasiyana hwezvigadzirwa izvi maererano nesimba remuchina, kudzivirirwa kwechikafu kubva mukusvibiswa), kushivirira kwekudhinda, kusapisa kupisa, kutaridzika kwekuona (semuenzaniso, kupenya kwakanyanya uye kujeka), kudzokororwa, uye mutengo-kushanda ndizvo zvinogadzira. vanobuda pachena.

Pakati pavo, mafirimu epurasitiki anoshandiswa mukuputira anochinjika mumhando dzakasiyana siyana dzezvinhu, kusanganisira zvinotevera:

Polyethylene (PE): kusanganisira yakaderera-density polyethylene (LDPE) uye mutsara yakaderera-density polyethylene (LLDPE), inowanzoshandiswa mukati memukati wezvokudya zvekuputira zvinhu, ine yakanaka yekupisa chisimbiso zvinhu uye kushanduka.

Polypropylene (PP): inowanzoshandiswa mukugadzira firimu, ine yakanakisa kupisa kupisa uye kupikisa kwemakemikari, inowanzoshandiswa muzvinyorwa zvepasi.

Polyester (PET): inowanzo shandiswa seyekunze kana yepakati dhizaini yekurongedza nekuda kweiyo yakanaka mechanical zvinhu uye pachena, inopa simba uye aesthetics.

Nylon (PA): inopa zvakanaka zvipingamupinyi zvivakwa uye inowanzoshandiswa pakurongedza inoda yakakwirira chipingamupinyi kuita.

Ethylene vinyl acetate copolymer (EVA): Inopa kuchinjika kwakanaka uye kunamatira uye inowanzoshandiswa sechisimbiso chekupisa.

Polyvinylidene dichloride (PVDC): ine yakakwira mhepo uye hunyoro inodzivirira zvivakwa, inowanzoshandiswa mukurongedza inoda kutsva kwenguva refu.

Ethylene Vinyl Doro Copolymer (EVOH): inopa yakanakisa okisijeni chipingamupinyi zvivakwa sechivhariso layer.

Polyvinyl chloride (PVC): inoshandiswa mune mamwe maapplication, asi kushandiswa kwayo kunogumira nekuda kwezvakatipoteredza uye hutano zvinetswa.

Bio-based zvinhu: senge polylactic acid (PLA), seimwe yezvakatipoteredza ine hushamwari zvimwe zvinhu zvine biodegradability yakanaka.

Biodegradable zvinhu: ari kugadzirwa kuti aderedze kukanganiswa kwezvakatipoteredza kwekurongedza.

Multi-layer co-extruded composite mafirimu: Multi-layer musanganiswa wePA, EVOH, PVDC ane resin akadai PE, EVA, PP, nezvimwewo kuti ipe yakakwirira chipingamupinyi zvivakwa.

Zvishandiso izvi zvinogona kushandiswa zvega kana kusanganiswa kugadzira mafirimu akaumbwa kuti asangane nezvinodiwa zvekurongedza zvakasiyana senge zvipingamupinyi zvivakwa, kupisa sealability, simba remuchina uye aesthetics. Mukurongedza kuchinjika, zvinhu izvi zvinowanzo kusanganiswa nelamination kana co-extrusion maitiro kuti aumbe kurongedza zvinhu zvine chaiwo mabasa.

Maitiro ekugadzirisa sei dambudziko rePE, PP, PET, PA uye zvimwe zvinhu mukugadzirisa extrusion process inowanzoitika kune hurema.?

Zvishandiso zviri pamusoro, zvakaita sePE, PP, PET, PA, nezvimwewo, zvinowanzofa muromo kuvaka-up, zvishoma nezvishoma extrusion rates, kunyunguduka kunyunguduka, uye yakaremara extruded nzvimbo panguva yekugadzirisa uye extrusion. Kazhinji, vagadziri vakuru vanozowedzera fluorinated polymer PPA kugadzirisa aids kuvandudza mashandiro ekugadzirisa. Nekudaro, mumakore achangopfuura, nekuwedzera kuziva kwekuchengetedzwa kwezvakatipoteredza uye yakarongwa Fluoride Restriction Order, kutsvaga dzimwe nzira dzefluorinated polymer PPA kugadzirisa aids rave basa rekukurumidzira.

Pasi rose, PFAS inoshandiswa zvakanyanya muzvigadzirwa zvakawanda zvemaindasitiri nevatengi, asi njodzi inogona kuitika kune zvakatipoteredza uye hutano hwevanhu zvakakonzera kushushikana kwakapararira. NeEuropean Chemicals Agency (ECHA) ichiita veruzhinji kurambidzwa kwePFAS.

Muna 2023, SILIKE's R&D timu yakapindura maitiro enguva uye yakaisa simba rakawanda mukushandisa yazvino tekinoroji nzira uye kufunga kwekuvandudza kusimudzira.PFAS-yemahara polymer kugadzirisa aids (PPAs), iyo inopa rubatsiro rwakanaka mukuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba. Ichi chigadzirwa chinovimbisa kuita kwekugadzirisa zvinhu uye kunaka uku uchidzivirira njodzi dzezvakatipoteredza uye hutano dzinogona kuunza zvechinyakare PFAS makomisheni.

SILIKE SILIMER PFAS-yemahara PPA masterbatch ndeye PFAS-isina polymer kugadzirisa rubatsiro (PPA)yakaunzwa neSilicone. Iyo yekuwedzera ndeye organically modified polysiloxane, iyo inotora mukana weyakanakisa yekutanga lubrication maitiro epolysiloxanes uye polar mhedzisiro yemapoka akagadziridzwa kutama uye kuita pamichina yekugadzirisa panguva yekugadziriswa.

SILIKE SILIMER PFAS-yemahara PPA masterbatchinogona kutsiva yakakwana yefluorine-yakavakirwa PPA kugadzirisa aids, kuwedzera diki kunogona kunyatso kuvandudza resin fluidity, processability, uye lubricity uye pamusoro pemasikirwo epurasitiki extrusion, kubvisa kunyunguduka kunyunguduka, kunatsiridza kupfeka kuramba, kuderedza coefficient of friction. , kunatsiridza kugadzirwa uye kunaka kwechigadzirwa, asiwo zvakatipoteredza uye zvakachengeteka.

SILIKE SILIMER PFAS-yemahara PPA masterbatchine zvakasiyana-siyana zvekushandisa, kwete chete kwemafirimu epurasitiki, asiwo kune waya uye tambo, machubhu, mavara masterbatches, petrochemical industry nezvimwe zvakadaro.

Kana iwe uri mune inoshanduka yekurongedza indasitiri uye uri kutsvaga kuvandudza kukwikwidza kwezvigadzirwa zvako, unogona kushandisa.SILIKE's PFAS-yemahara PPA yekuwedzera.
