BOPP (OPP)——filimu ya biaxially oriented polypropylene, yomwe ndi filimu yopangidwa ndi polypropylene monga chinthu chachikulu komanso chotambasulidwa ndi njira ya filimu yosalala. Ili ndi mphamvu zolimba kwambiri, zolimba kwambiri, komanso zowonekera. Zabwino, zonyezimira bwino, magwiridwe antchito otsika osasunthika, magwiridwe antchito abwino kwambiri osindikizira ndikumatira, mpweya wabwino kwambiri wamadzi ndi zotchinga, motero amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana onyamula.

PE - polyethylene. Ndi utomoni wa thermoplastic wopezedwa ndi polymerization wa ethylene. M'makampani, amaphatikizanso ma copolymers a ethylene ndi pang'ono α-olefins. Polyethylene ndi yopanda fungo, yopanda poizoni, imakhala ngati sera, imakhala ndi kutentha kochepa kwambiri (kutentha kotsika kwambiri kumatha kufika -100~-70 ° C), kukhazikika kwa mankhwala abwino, ndipo kungathe kupirira kukokoloka kwa asidi ndi alkali (osagonjetsedwa ndi okosijeni) chikhalidwe cha asidi). Insoluble mu zosungunulira wamba kutentha firiji, otsika mayamwidwe madzi, kwambiri kutchinjiriza magetsi.

CPP-ndiko kuti, filimu ya polypropylene, yomwe imadziwikanso kuti filimu yosatambasula ya polypropylene, ikhoza kugawidwa mu filimu ya CPP (General CPP, GCPP mwachidule) ndi filimu ya CPP yotayidwa ndi aluminiyamu (Metalize CPP, MCPP mwachidule) filimu molingana ndi ntchito zosiyanasiyana Ndipo kuphika kalasi CPP (Retort CPP, RCPP mwachidule) filimu, etc.

VMPET - amatanthauza filimu yopangidwa ndi poliyesitala. Amagwiritsidwa ntchito ku filimu yoteteza pamapaketi a chakudya chowuma ndi chotukuka monga mabisiketi ndi zopaka kunja kwa mankhwala ndi zodzoladzola.

Filimu ya aluminiyamu imakhala ndi mawonekedwe a filimu yapulasitiki komanso mawonekedwe achitsulo. Ntchito ya aluminiyamu plating pamwamba pa filimuyi ndi mthunzi ndi kuteteza ultraviolet kuwala, amene osati kutalikitsa alumali moyo wa nkhani, komanso bwino kuwala kwa filimuyo. , kugwiritsa ntchito filimu yopangidwa ndi aluminiyamu m'matumba ophatikizika ndiambiri. Pakali pano, amagwiritsidwa ntchito kwambiri poyika zakudya zouma ndi zofufuma monga mabisiketi, komanso zopangira kunja kwa mankhwala ndi zodzoladzola.

PET - yomwe imadziwikanso kuti filimu ya polyester yosagwira kutentha kwambiri. Ili ndi katundu wabwino kwambiri wakuthupi, katundu wamankhwala ndi kukhazikika kwa mawonekedwe, kuwonekera, ndi kubwezeretsedwanso, ndipo angagwiritsidwe ntchito pojambula maginito, zipangizo zowonetsera zithunzi, zamagetsi, magetsi, mafilimu a mafakitale, zokongoletsera zamapaketi, chitetezo chazenera, magalasi owoneka bwino Kuteteza pamwamba ndi zina. High kutentha kugonjetsedwa poliyesitala chitsanzo filimu: FBDW (mbali imodzi matte wakuda) FBSW (awiri mbali matte wakuda) High kutentha kugonjetsedwa poliyesitala specifications filimu Makulidwe m'lifupi mpukutu m'mimba mwake pachimake 38μm ~ 250μm 500~1080mm 300mm~650mm 76mm (3 〞 52mm) malinga ndi zosowa zenizeni. Utali wanthawi zonse wa mpukutu wa kanema ndi 3000m kapena 6000 wofanana ndi 25μm.

PE-LLD—Linear Low Density Polyethylene (LLDPE), yopanda poizoni, yopanda fungo, tinthu zoyera zamkaka zopanda fungo zokhala ndi kachulukidwe ka 0.918~0.935g/cm3. Poyerekeza ndi LDPE, ili ndi kutentha kwakukulu kofewa ndi kutentha kosungunuka, ndipo ili ndi ubwino wa mphamvu zambiri, kulimba kwabwino, kukhazikika kwakukulu, kukana kutentha, ndi kuzizira. Ilinso ndi kukana kwabwino kwa kupsinjika kwa chilengedwe, kulimba kwamphamvu, komanso kulimba. Kugwetsa mphamvu ndi katundu wina, ndipo akhoza kugonjetsedwa ndi zidulo, alkalis, zosungunulira organic, etc. ndipo chimagwiritsidwa ntchito m'mafakitale, ulimi, mankhwala, ukhondo ndi zofunika tsiku ndi tsiku. Linear low-density polyethylene (LLDPE) utomoni, womwe umadziwika kuti polyethylene ya m'badwo wachitatu, uli ndi mphamvu zolimba, kung'ambika, kukana kupsinjika kwa chilengedwe, kukana kutentha pang'ono, komanso kukana kwa kutentha ndi nkhonya ndizopambana kwambiri.

BOPA (NYLON) - ndi chidule cha Chingerezi cha filimu ya Biaxially oriented polyamide (nayiloni). Kanema wa nayiloni wa Biaxially oriented nylon (BOPA) ndichinthu chofunikira kwambiri popanga zida zophatikizira zophatikizika, ndipo chakhala chachitatu chachikulu kwambiri pakuyika pambuyo pa makanema a BOPP ndi BOPET.

Filimu ya nayiloni (yomwe imatchedwanso PA) Kanema wa nayiloni ndi filimu yolimba kwambiri yowonekera bwino, yonyezimira bwino, yolimba kwambiri komanso yolimba, komanso kukana kutentha, kuzizira komanso kukana mafuta. Good kukana zosungunulira organic, kukana abrasion, kukana puncture, ndi zofewa, kwambiri kukana mpweya, koma chotchinga osauka nthunzi madzi, mayamwidwe mkulu chinyezi, permeability chinyezi, osauka kutentha sealability, oyenera Iwo ndi oyenera ma CD zinthu olimba, monga mafuta chakudya, mankhwala nyama, chakudya chokazinga, vacuum-odzaza chakudya, chakudya chotentha, etc.

Makanema athu ndi ma laminate amapanga chosanjikiza chotchingira chomwe chimateteza malonda anu kuti asawonongeke akamapakidwa. Mitundu yambiri yazoyikapo kuphatikiza polyethylene, poliyesitala, nayiloni, ndi zina zomwe zalembedwa pansipa zimagwiritsidwa ntchito popanga chotchinga ichi.
