LDPE:High-pressure polyethylene inoreva polyethylene inogadzirwa ne-high-pressure process, iyo yakaderera-density polyethylene.
HDPE:Low-pressure polyethylene zvinoreva kuti polyethylene inogadzirwa neiyo yakaderera-pressure process inogona kuburitsa yakakwira-density polyethylene.
LLDPE: Linear Low Density Polyethylene
LDPE yakaderera-density polyethylene ipurasitiki zvinhu, iyo inokodzera akasiyana-siyana ekuumba maitiro eiyo thermoplastic molding uye ine yakanaka yekuumba processability.Chinangwa chikuru ndechekugadzira zvigadzirwa zvemufirimu, asiwo zvekugadzira majekiseni ekugadzira zvigadzirwa, midziyo yekurapa, mushonga uye chikafu chekurongedza zvinhu, kuvhuvhuta kuumba maburi akaumbwa zvigadzirwa, nezvimwe.
HDPE is non-polar thermoplastic resin ine high crystallinity.Kuonekwa kweiyo HDPE yepakutanga ine mukaka chena, uye chikamu chakatetepa chinopenya kune imwe nhanho.PE ine yakanakisa kuramba kune mazhinji emumba uye maindasitiri makemikari.Iine zvinhu zvakanaka zvemagetsi, kunyanya iyo yakakwirira dielectric simba rekudzivirira, zvichiita kuti ive yakakodzera kwazvo kune waya netambo.
LLDPE mutsara wakaderera-density polyethylene haina chepfu, haina kuravira, uye isina hwema mukaka chena zvimedu.Kuenzaniswa neLDPE, ine tembiricha yakapfava yepamusoro uye tembiricha yekunyungudika.Iine simba rakakwirira, kusimba kwakanaka, kusimba kwepamusoro, kupikisa kupisa uye kutonhora kwakanaka.Uye mamwe mabhenefiti, zvakare ane yakanaka kwezvakatipoteredza kusagadzikana crack resistance, kukanganisa kuramba, kubvarura kuramba uye zvimwe zvivakwa.Inopikisa acids, alkalis, organic solvents, nezvimwe.
LGLPAK inogona kupa zvigadzirwa zvemafirimu epurasitiki neLDPE, HDPE, LLDPE sezvinhu zvakasvibiswa, zvakadai sebhegi remarara, bhegi rezvokudya, bhegi rekutenga, uye marudzi akasiyana-siyana emabhegi, akadai seFlat bag, T-shirt bag, Die-cut;Nyeredzi-chisimbiso bhegi, Drawstring bag.
