Mitundu ya Polypropylene: Decoding OPP, BOPP, ndi CPP Mafilimu

Kanema wa OPP ndi filimu ya polypropylene yotchedwa co-extruded oriented polypropylene (OPP) filimu chifukwa kamangidwe kake kamakhala ndi zigawo zambiri. Ngati pali njira yotambasulira yozungulira pokonza, imatchedwa bi-directional oriented polypropylene film (BOPP). Enawo ndi filimu ya polypropylene (CPP), m'malo mwa njira yolumikizirana. Makhalidwe ndi ntchito za mafilimu atatuwa zimasiyanitsidwa.

UP Movie:Zoyambira

OPP: oriented polypropylene (filimu), elongated polypropylene, ndi polypropylene. Zogulitsa zazikulu za OPP:

1. UP Tape: Filimu ya polypropylene ngati gawo lapansi, yokhala ndi mphamvu zolimba kwambiri, zopepuka, zopanda poizoni, zopanda pake, zachilengedwe, zogwiritsa ntchito zosiyanasiyana, ndi zabwino zina;
2. Mabotolo a OPP: Zopepuka, zotsika mtengo, kuwonekera bwino, kukana kutentha kwabwino, koyenera kudzazidwa kotentha.
3. Zithunzi za OPP : Zokhudzana ndi zolemba zamapepala, ali ndi ubwino wowonekera, mphamvu zambiri, kukana chinyezi, komanso zosavuta kugwa. Ngakhale mtengo wakula, mutha kupeza mawonekedwe abwino olembera ndikugwiritsa ntchito zotsatira zake. Ndi chitukuko cha njira zosindikizira zapakhomo ndi teknoloji yokutira, kupanga zolemba za mafilimu odzipangira okha ndi kusindikiza zolemba mafilimu sikulinso mavuto; zitha kunenedweratu kuti kugwiritsidwa ntchito kwapakhomo kwa zilembo za OPP kupitilira kuwonjezeka.

Kanema wa BOPP: Kusinthasintha ndi Kugwiritsa Ntchito

BOPP: filimu yopangidwa ndi biaxially polypropylene, komanso mtundu wa polypropylene.

Makanema omwe amagwiritsidwa ntchito nthawi zambiri a BOPP amaphatikizapo filimu wamba ya biaxially oriented polypropylene, filimu ya polypropylene yotchinga kutentha, filimu yonyamula ndudu, filimu ya ngale ya biaxially, polypropylene metalized film, filimu ya matte ndi zina zotero.

Kanema wa BOPP alinso ndi zolakwika, monga kudzikundikira kosavuta kwa magetsi osasunthika komanso kusowa kwa kutentha kwa kutentha. Mumzere wopanga kwambiri, filimu ya BOPP imakonda kukhala ndi magetsi osasunthika, chifukwa chake pamafunika kukhazikitsa chochotsera magetsi. Kuti mupeze filimu ya BOPP yotsekedwa ndi kutentha, chithandizo cha filimu ya BOPP pamwamba pa korona chikhoza kupakidwa ndi zomatira zomatira zotentha, monga PVDC latex, EVA latex, etc. co-extruded composite njira yopangira filimu ya BOPP yotsekera kutentha.

Ntchito zazikulu zamakanema osiyanasiyana ndi izi:

1. Kanema wamba wa BOPP: Amagwiritsidwa ntchito makamaka kusindikiza, kupanga thumba, tepi yomatira, ndikuphatikiza ndi magawo ena.
2. Kanema Wosindikiza Kutentha kwa BOPP: Amagwiritsidwa ntchito makamaka kusindikiza, kupanga thumba, etc.
3. Kanema Wopaka Ndudu wa BOPP: Amagwiritsidwa ntchito polongedza ndudu zothamanga kwambiri.
4. filimu ya BOPP Pearlescent: Amagwiritsidwa ntchito pazakudya ndi zofunikira zatsiku ndi tsiku pambuyo posindikiza.
5. Bopp Metallized FilmAmagwiritsidwa ntchito ngati sopo, chakudya, ndudu, zodzoladzola, mankhwala, ndi mabokosi ena oyikamo.
6. Kanema wa Matte BOPP: Amagwiritsidwa ntchito ngati sopo, chakudya, ndudu, zodzoladzola, mankhwala, ndi mabokosi olongedza katundu.

Filimu ya CPP: Katundu ndi Zomwe Zingatheke

C kuwonekera bwino, gloss mkulu, kuuma bwino, phokoso chinyezi chotchinga, kukana kutentha kwambiri, kusindikiza kosavuta kutentha, ndi zina zotero.

Filimu ya CPP itatha kusindikiza, kupanga thumba, yoyenera

1. Zovala, zoluka, ndi zikwama zamaluwa
2. Zolemba ndi Albums filimu
3. Zakudya zopakidwa ndizitsulo
4. Kanema wazitsulo woyenera kuyika zotchinga ndi zokongoletsera

Zomwe zingagwiritsidwe ntchito zimaphatikizaponso kudzaza chakudya, chowonjezera cha confectionery (filimu yopotoka), kuyika mankhwala (matumba olowetsedwa), kusintha PVC mu Albums, zikwatu, ndi zolemba, mapepala opangira, matepi odzimatirira, zosungira makhadi a bizinesi, zomangira mphete, ndi kuyimirira. ma composite.

CPP ili ndi kukana kwambiri kutentha. Popeza kufewetsa kwa PP kuli pafupi ndi 140 ° C, filimu yamtunduwu ingagwiritsidwe ntchito podzaza moto, matumba a nthunzi, mapepala a aseptic, ndi zina. Ndizinthu zomwe mungasankhe m'malo monga zopangira mkate kapena ma laminate, kuphatikiza ndi asidi wabwino kwambiri, alkali, komanso kukana mafuta. Ndizotetezeka pokhudzana ndi chakudya, zimakhala ndi mawonekedwe abwino kwambiri, sizikhudza kukoma kwa chakudya mkati, ndipo mitundu yosiyanasiyana ya utomoni imatha kusankhidwa kuti mupeze zomwe mukufuna.
