PE kupisa shrinkable firimu ruzivo

Kurongeka kweLDPE kupisa kunopisa firimu

LDPE kupisa kupisa shrinkable mafirimu akakamurwa kuita mapoka maviri: muchinjiko-yakabatana uye isina-muchinjika-yakabatana.Kazhinji, vagadziri vanoshandisa mbishi zvinhu neMFR ye0.3-1.5g/10min pavanenge vachigadzira mafirimu asina-muchinjika-akabatana eLDPE anopisa-anopisa.Iyo yakaderera iyo melt index, iyo yakawanda yunifomu iyo shrinkage performance.Uye iyo yakakura kusimba kwesimba, iyo inonyanya kukodzera kurongedza.Vamwe vagadziri vanoshandisa kurapa kwemwaranzi mukugadzira kuvandudza akasiyana siyana emafirimu anopisa anopisa.
PE kupisa kupisa shrinkable firimu inogona kusangana nekurongedza zvinodiwa zvezvakawanda zvigadzirwa, uye ndiyo inonyanya kushandiswa kupisa kupisa shrinkable firimu.Iyo MI inoshandiswa yeLDPE zvidimbu ndeye 0.3-1.5g / min.Heavy packaging shrink film or shrink film ine high simba zvinodiwa, shandisa LDPE zvidimbu zvine muganho wakaderera weMI, LDPE molding tembiricha iri 130-180 ℃, pre-inotonhorera nemhepo inotonhora iri pasi pe25 ℃, uye wozofuridzira padhuze netambo yechando, kamwe Longitudinal uye transverse kutambanudza, iyo yakazara kutambanudza reshiyo inogona kusvika 15-35, uye ipapo iyo firimu inodzimwa pa10-25 ° C kumhepo kana kutapudza firimu.The general shrinkage rate ndeye 30% -50%.
Features:
1. Iyo uncrosslinked LDPE shrink firimu yakapfava, ine yakanaka kukanganisa kurwisa, uye ine imwe simba rekubvarura;
2. Good low temperature resistance;
3. Zviri nyore kugadzirisa uye kuumba, nyore kupisa chisimbiso bhegi;
4. Hapana shrinkage inoitika panguva yekuchengetedza.Shrink kuputira girazi, Ceramics, zvokudya, zvokuvakisa, makemikari, mapallets, etc. Ukobvu chiedza packaging is 0.02-0.06mm, uye ukobvu rinorema uye hombe pallet packaging i 0.075-0.25mm.

Zvimiro zveLDPE shrink firimu:
1. Mutete firimu ukobvu ndiko 0.02-0.05mm, pakati mhando 0.05-0.10mm, uye gobvu mhando 0.10-0.15mm;
2. Simba rekusimba i28-38MPa yemhando yakatetepa, 20-30MPa yemhando yepakati, uye 20-28MPa yemhando gobvu;
3. Shrinkage mwero yemhando yakatetepa ndeye 55% -65%, yepakati mhando i45% -60%, gobvu mhando 30% -50%;shrinkage tembiricha yemafuta yekugezera ndeye 110-120 ℃, mhepo inopisa ndeye 170-180 ℃;
4. Shrinkage nguva ndeye 5-10s yemhando yakaonda uye 20-30s yemhando gobvu.
Ukobvu hudiki hwefirimu rekuputira pasi pe400kg i120μm, 800kg inoda 150μm ukobvu, uye 1200kg zvinhu zvinoda LDPE shrink firimu rine 200μm ukobvu.
