Mau oyamba kuti mumvetsetse kusiyana pakati pa filimu ya CPP, filimu ya OPP, filimu ya BOPP ndi filimu ya MOPP

Momwe mungaweruzire opp,cpp,bopp,VMopp,chonde onani zotsatirazi.

PP ndi dzina la polypropylene. Malingana ndi katundu ndi cholinga cha ntchito, mitundu yosiyanasiyana ya PP inalengedwa.

CPP filimuyi imaponyedwa filimu ya polypropylene, yomwe imadziwikanso kuti filimu yosatambasula ya polypropylene, yomwe imatha kugawidwa mufilimu ya CPP (General CPP), filimu yazitsulo ya CPP (Metalize CPP, MCPP) ndi Retort CPP (Retort CPP, RCPP ) filimu, ndi zina zotero.

MayiFzakudya

- Mtengo wotsika kuposa makanema ena monga LLDPE, LDPE, HDPE, PET etc.

-Kuuma kwakukulu kuposa filimu ya PE.

-Chinyezi chabwino kwambiri komanso zolepheretsa fungo.

- Multifunctional, itha kugwiritsidwa ntchito ngati filimu yoyambira.

- Metallization Coating ilipo.

-Monga zopangira zakudya ndi katundu komanso zoyika zakunja, zimakhala ndi mawonekedwe abwino kwambiri ndipo zimatha kupangitsa kuti chinthucho chiwoneke bwino kudzera muzotengera.

Kugwiritsa ntchito filimu ya CPP

Filimu ya Cpp ikhoza kugwiritsidwa ntchito pamisika ili pansipa. Pambuyo posindikiza kapena kupukuta.

1.laminated matumba mkati filimu
2.(Aluminized film) Filimu yazitsulo yopangira zotchinga ndi zokongoletsera. Pambuyo pa vacuum aluminizing, imatha kuphatikizidwa ndi BOPP, BOPA ndi magawo ena opangira tiyi wapamwamba kwambiri, chakudya chokazinga chokazinga, mabisiketi, ndi zina zambiri.
3.(Retorting film) CPP yokhala ndi kukana kwambiri kutentha. Popeza kufewetsa kwa PP kuli pafupi ndi 140 ° C, filimu yamtunduwu imatha kugwiritsidwa ntchito podzaza moto, matumba obweza, ma phukusi a aseptic ndi magawo ena. Kuphatikiza apo, imakhala ndi kukana kwambiri kwa asidi, kukana kwa alkali ndi kukana kwamafuta, kupangitsa kuti ikhale chisankho chabwino kwambiri chopangira mkate kapena zida zam'madzi. Ndiwotetezeka kukhudzana ndi chakudya, imakhala ndi mawonekedwe abwino kwambiri, imasunga kukoma kwa chakudya mkati, ndipo pali mitundu yosiyanasiyana ya utomoni wokhala ndi mawonekedwe osiyanasiyana.
4.(Functional film) Ntchito zomwe zingatheke zikuphatikizapo: kulongedza chakudya, kuyika maswiti (filimu yopotoka), kuyika mankhwala (matumba olowetsedwa), kusintha PVC muzithunzi za zithunzi, zikwatu ndi zikalata, mapepala opangira, osawumitsa Tepi Yomatira, zosungira makhadi a bizinesi. , zikwatu za mphete, ndi ma composites amatumba oyimilira.
5.CPP Misika yatsopano yogwiritsira ntchito, monga ma DVD ndi ma audio-visual box packaging, ma bakery, masamba ndi zipatso zotsutsana ndi chifunga filimu ndi maluwa, ndi mapepala opangira malemba.

Mafilimu a OPP

OPP ndi Oriented Polypropylene.

Mawonekedwe

Kanema wa BOPP ndiwofunikira kwambiri ngati zinthu zosinthira. Kanema wa BOPP ndi wowonekera, wopanda fungo, wosakoma, wopanda poizoni, ndipo ali ndi mphamvu zolimba kwambiri, kulimba, kulimba, kulimba, kuwonekera kwambiri.

Kuchiza kwa filimu ya BOPP ya corona pamtunda kumafunika musanayambe gluing kapena kusindikiza. Pambuyo pa chithandizo cha corona, filimu ya BOPP imakhala yosinthika bwino yosindikiza, ndipo imatha kusindikizidwa mumitundu kuti ipeze mawonekedwe owoneka bwino, chifukwa chake imagwiritsidwa ntchito ngati gawo lapamwamba la filimu yophatikizika kapena laminated.

Zosowa:

Filimu ya BOPP imakhalanso ndi zofooka, monga zosavuta kusonkhanitsa magetsi osasunthika, osatsekedwa kutentha, etc. Pamzere wothamanga kwambiri, mafilimu a BOPP amakonda magetsi osasunthika, ndipo zotulutsa static ziyenera kuikidwa.Kuti apeze kutentha- filimu ya BOPP yosindikizidwa, zomatira zotsekemera zotentha, monga PVDC latex, EVA latex, etc., zimatha kukwiriridwa pamwamba pa filimu ya BOPP pambuyo pa mankhwala a corona, zosungunulira zosungunulira zimathanso kukhala zokutira, komanso zokutira kapena zokutira zowonjezera zitha kugwiritsidwanso ntchito. . Co-extrusion composite njira yopangira filimu ya BOPP yotsekedwa ndi kutentha.

Zogwiritsa

Kuti mupeze magwiridwe antchito bwino, njira zophatikizika zamitundu yambiri zimagwiritsidwa ntchito popanga. BOPP imatha kuphatikizidwa ndi zida zambiri zosiyanasiyana kuti ikwaniritse zosowa zapadera. Mwachitsanzo, BOPP ikhoza kuphatikizidwa ndi LDPE, CPP, PE, PT, PO, PVA, etc. kuti apeze chotchinga chachikulu cha gasi, chotchinga cha chinyezi, kuwonekera, kutentha kwakukulu ndi kutsika kwa kutentha, kukana kuphika ndi kukana mafuta. Makanema ophatikizika osiyanasiyana atha kugwiritsidwa ntchito pazakudya zamafuta ambiri, chakudya chokoma, chakudya chowuma, chakudya choviikidwa, mitundu yonse yazakudya zophikidwa, zikondamoyo, makeke ampunga ndi zoyika zina.

 Chithunzi cha VMOPPKanema

VMOPP ndi filimu ya Aluminized BOPP, wosanjikiza wopyapyala wa aluminiyumu wokutidwa pamwamba pa filimu ya BOPP kuti ikhale ndi chitsulo chonyezimira komanso kuti iwonetsere. Zomwe zimapangidwira ndi izi:

1. Filimu yopangidwa ndi aluminiyamu imakhala ndi zonyezimira zabwino kwambiri komanso zowoneka bwino, zimapereka chisangalalo chimodzi. Kuigwiritsa ntchito poyika katundu kumawonjezera kuwoneka kwazinthu.
2. Kanema wa aluminiyumu ali ndi zida zabwino kwambiri zotchingira mpweya, zotchinga chinyezi, zida za shading komanso kusungirako kununkhira. Sikuti ali ndi mphamvu zotchinga katundu kwa mpweya ndi nthunzi wa madzi, komanso akhoza kutsekereza pafupifupi cheza ultraviolet, looneka kuwala ndi infuraredi cheza, amene angathe kutalikitsa alumali moyo wa nkhani. Pazakudya, mankhwala ndi zinthu zina zomwe zimafunikira kukulitsa moyo wa alumali, ndi chisankho chabwino kugwiritsa ntchito filimu yopangidwa ndi aluminiyamu ngati zoyika, zomwe zingalepheretse chakudya kapena zomwe zili mkati kuti zisawonongeke chifukwa cha kuyamwa kwa chinyezi, kutulutsa mpweya, kuwala, metamorphism, etc. . The aluminiyamu filimu komanso katundu monga fungo kusunga, fungo kufala mlingo ndi otsika, amene akhoza kusunga fungo la nkhani kwa nthawi yaitali. Chifukwa chake, filimu yopangidwa ndi aluminiyamu ndi chinthu chabwino kwambiri chotchingira ma CD.
3. Aluminiyamu filimu angathenso m'malo zotayidwa zojambulazo kwa mitundu yambiri ya zotchinga ma CD matumba ndi film.The kuchuluka kwa zotayidwa ntchito kwambiri yafupika, amene osati kupulumutsa mphamvu ndi zipangizo, komanso amachepetsa mtengo wa katundu ma CD kumlingo.
4. Wosanjikiza zotayidwa pamwamba pa VMOPP ndi madutsidwe wabwino ndipo akhoza kuthetsa electrostatic ntchito. Choncho, katundu wosindikiza ndi wabwino, makamaka pamene akunyamula zinthu za powdery, akhoza kuonetsetsa kuti phukusili likukhazikika.
