PE polyethylene (yonse pamodzi, ikhoza kuphatikizapo PE-LD, PE-LLD, PE-MLLD, PE-HD, PE yosinthidwa, ndi zina zotero):

——PE-HD High Density Polyethylene

——PE-LD Polyethylene Yochepa Kwambiri

——PE-LLD yolunjika yotsika kwambiri polyethylene

——PE-MD polyethylene yapakatikati yokhuthala

——Chikwama chachitsulo cha PE-MLLD chopanda kuchuluka kwa polyethylene

PO polyolefin

PT cellophane

VMCPP vacuum aluminiyamu yopangidwa ndi polypropylene

Polyester yopangidwa ndi aluminiyamu ya VMPET

BOPP (OPP)——filimu ya polypropylene yolunjika mbali zonse ziwiri, yomwe ndi filimu yopangidwa ndi polypropylene ngati chinthu chachikulu chopangira zinthu ndipo imatambasulidwa mbali zonse ziwiri pogwiritsa ntchito njira ya flat film. Ili ndi mphamvu yokoka kwambiri, kulimba kwambiri, komanso kuwonekera bwino. Yabwino, yowala bwino, yogwira ntchito pang'ono, yosindikiza bwino komanso yomatira bwino, nthunzi yabwino kwambiri yamadzi ndi zotchinga, kotero imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana opangira zinthu.

PE - Polyethylene. Ndi utomoni wa thermoplastic womwe umapezeka popolima ethylene. Mu mafakitale, umaphatikizaponso ma copolymer a ethylene ndi α-olefins ochepa. Polyethylene ndi yopanda fungo, si poizoni, imamveka ngati sera, imakhala ndi kukana kutentha kochepa (kutentha kotsika kwambiri komwe kumagwira ntchito kumatha kufika -100~-70°C), imakhala yolimba bwino pa mankhwala, ndipo imatha kupirira kukokoloka kwa asidi ndi alkali (kosagwirizana ndi okosijeni) kwa asidi). Sisungunuka m'madzi osungunuka omwe amapezeka kutentha kwa chipinda, imayamwa madzi pang'ono, imateteza bwino magetsi.

CPP—ndiko kuti, filimu ya polypropylene yopangidwa ndi anthu, yomwe imadziwikanso kuti filimu ya polypropylene yosatambasulidwa, ingagawidwe m'magulu awiri: filimu ya general CPP (General CPP, GCPP yachidule) ndi filimu ya CPP (Metalize CPP, MCPP yachidule) yokhala ndi aluminiyamu malinga ndi ntchito zosiyanasiyana.

VMPET - imatanthauza filimu yopangidwa ndi aluminiyamu ya polyester. Imayikidwa pa filimu yoteteza yomwe ili pa phukusi la chakudya chouma komanso chofufumitsa monga mabisiketi ndi phukusi lakunja la mankhwala ndi zodzoladzola zina.

Filimu yopangidwa ndi aluminiyamu ili ndi mawonekedwe ofanana ndi filimu ya pulasitiki komanso mawonekedwe ofanana ndi chitsulo. Ntchito ya aluminiyamu yophimba pamwamba pa filimuyi ndikuteteza kuwala kwa ultraviolet, komwe sikuti kumangowonjezera nthawi yosungiramo zinthu, komanso kumawonjezera kuwala kwa filimuyi. Kugwiritsa ntchito filimu yopangidwa ndi aluminiyamu m'mabokosi ophatikizika ndi kwakukulu kwambiri. Pakadali pano, imagwiritsidwa ntchito kwambiri popaka chakudya chouma komanso chofufumitsa monga mabisiketi, komanso popaka mankhwala ndi zodzoladzola zakunja.

PET - yomwe imadziwikanso kuti filimu ya polyester yosatentha kwambiri. Ili ndi makhalidwe abwino kwambiri, mankhwala komanso kukhazikika kwa mawonekedwe, kuwonekera bwino, komanso kubwezeretsanso, ndipo ingagwiritsidwe ntchito kwambiri pojambula maginito, zinthu zowunikira kuwala, zamagetsi, kutchinjiriza magetsi, mafilimu amafakitale, zokongoletsera ma CD, chitetezo cha sikirini, magalasi owonera Chitetezo cha pamwamba ndi zina. Mtundu wa filimu ya polyester yosatentha kwambiri: FBDW (wakuda wokhala ndi mbali imodzi) FBSW (wakuda wokhala ndi mbali ziwiri) Zofotokozera za filimu ya polyester yosatentha kwambiri Kunenepa m'lifupi mpukutu m'mimba mwake pakatikati 38μm~250μm 500~1080mm 300mm~650mm 76mm(3〞), 152mm (6〞) Dziwani: Mafotokozedwe a m'lifupi amatha kupangidwa malinga ndi zosowa zenizeni. Kutalika kwanthawi zonse kwa mpukutu wa filimu ndi 3000m kapena 6000 yofanana ndi 25μm.

PE-LLD—Linear Low Density Polyethylene (LLDPE), yopanda poizoni, yopanda kukoma, yopanda fungo la tinthu tating'onoting'ono toyera ngati mkaka tokhala ndi kachulukidwe ka 0.918 ~ 0.935g/cm3. Poyerekeza ndi LDPE, ili ndi kutentha kofewa kwambiri komanso kutentha kosungunuka, ndipo ili ndi ubwino wa mphamvu yayikulu, kulimba bwino, kulimba kwambiri, kukana kutentha, komanso kukana kuzizira. Ilinso ndi mphamvu yabwino yolimbana ndi kupsinjika kwa chilengedwe, mphamvu yokoka, komanso kulimba. Mphamvu yokoka ndi zinthu zina, ndipo imatha kupirira ma acid, alkali, zosungunulira zachilengedwe, ndi zina zotero ndipo imagwiritsidwa ntchito kwambiri m'magawo amakampani, ulimi, mankhwala, ukhondo ndi zofunikira za tsiku ndi tsiku. Utomoni wa polyethylene wocheperako (LLDPE), womwe umadziwika kuti polyethylene wa m'badwo wachitatu, uli ndi mphamvu yokoka, mphamvu yokoka, mphamvu yokoka, kukana kupsinjika kwa chilengedwe, kukana kutentha kochepa, komanso kukana kutentha ndi kubowola ndikwabwino kwambiri.

BOPA (NYLON) - ndi chidule cha filimu ya polyamide (nylon) yolumikizidwa ndi Biaxially. Filimu ya nayiloni yolumikizidwa ndi Biaxially (BOPA) ndi chinthu chofunikira kwambiri popanga zinthu zosiyanasiyana zophatikizira, ndipo yakhala chinthu chachitatu chachikulu chopangira zinthu pambuyo pa mafilimu a BOPP ndi BOPET.

Filimu ya nayiloni (yomwe imatchedwanso PA) Filimu ya nayiloni ndi filimu yolimba kwambiri yokhala ndi mawonekedwe abwino, kuwala bwino, mphamvu yayikulu yokoka komanso mphamvu yokoka, komanso kukana kutentha bwino, kukana kuzizira komanso kukana mafuta. Imakana bwino zosungunulira zachilengedwe, kukana kukwawa, kukana kubowoka, komanso kukana mpweya wabwino kwambiri, koma yolepheretsa nthunzi ya madzi, kuyamwa chinyezi kwambiri, kulowa kwa chinyezi, kukana kutentha kwambiri, yoyenera kulongedza zinthu zolimba, monga chakudya chamafuta ambiri, zinthu za nyama, chakudya chokazinga, chakudya chodzaza ndi vacuum, chakudya chophikidwa ndi nthunzi, ndi zina zotero.

Mafilimu ndi ma laminate athu amapanga chotetezera chomwe chimateteza chinthu chanu ku kuwonongeka kulikonse chikapakidwa. Mitundu yambiri ya zinthu zopakira kuphatikizapo polyethylene, polyester, nayiloni, ndi zina zomwe zatchulidwa pansipa zimagwiritsidwa ntchito popanga chotchinga cha laminate ichi.
