Zokometsera & Zosakaniza

PE co-extruded wakuda ndi woyera filimu: ali wabwino chotchinga mpweya katundu ndi kusinthasintha, ndipo nthawi zambiri ntchito ma CD zokometsera madzi monga soya msuzi ndi vinyo wosasa.

KPET/PE (manenedwe a PE ayenera kukhala osachepera 60μm): Imakhala ndi kukana kutentha kwabwino, chotchinga gasi ndi ntchito yosindikiza kutentha, ndipo imagwiritsidwa ntchito nthawi zambiri popaka zakudya za sauces (monga phala la soya, msuzi wa soya, ndi zina), ndipo ingagwiritsidwe ntchito pa 80 - 90 ° C Kuphika ndi kutseketsa pa kutentha kwakukulu.

KOP / PE, KPET / PE, KPA / PE, PET / Al / PE, BOPA / EVOH / PE, PA / PE, PA / PE / Al / PE: ali ndi zinthu zabwino zotchinga, kuphatikizapo kutsekereza mpweya, kununkhira, mafuta, ndi zina zotero, ndi mphamvu zambiri (palibe thumba losweka, palibe kutayikira kwamadzimadzi) ndi kutsutsa kobwerezabwereza, zomwe zimagwiritsidwa ntchito popanga supu. Pakati pawo, zotchinga za zida zonyamula zomwe zili ndi KPET, KPA, Al, ndi EVOH ndizamphamvu kuposa zida zina, koma mtengo wake ndi wokwera pang'ono.

KPA/LLDPE (kapena EVA), BOPA/VMPET/LLDPE (kapena EVA), PET/Al/PET/LLDPE (kapena EVA), PET/VMPET/LLDPE (kapena EVA), PET/Al/LLDPE (kapena EVA): KPA, Al, ndi VMPET zonse ndi zida zotchinga kwambiri, zokhala ndi mpweya wabwino kwambiri ndi chotchinga chamadzi, koma chotchinga chamadzi chimasungidwa bwino ndi chotchinga cham'madzi. zomwe zili. LLDPE (kapena EVA) ali kukana wabwino kusindikiza kuipitsidwa, kotero mphamvu zonse za zinthu High khalidwe, alumali moyo wautali, odana ndi makutidwe ndi okosijeni, kukana dzimbiri, kukana zabwino chisindikizo kuipitsidwa, zipangizo pamwamba angagwiritsidwe ntchito ma CD a sauces, sauces, zakumwa zamafuta kwambiri kapena zokometsera theka-olimba.
