Kodi mipukutu ya filimu ya pulasitiki yonyamula zakudya ndi yotani ndipo magulu awo ndi otani?

Filimu yonyamula imapangidwa makamaka ndi kusakaniza ndi kutulutsa ma resin angapo a polyethylene amitundu yosiyanasiyana.Ili ndi kukana kwa puncture, mphamvu zapamwamba komanso magwiridwe antchito apamwamba.

Kupaka mafilimuamagawidwa m'magulu asanu ndi awiri: PVC, CPP, OPP, CPE, ONY, PET ndi AL.

1. PVC

Angagwiritsidwe ntchito kupanga ma CD filimu, PVC kutentha shrinkable filimu, etc. Ntchito: PVC botolo chizindikiro.

2. Ponyani filimu ya polypropylene

Kanema wa Cast polypropylene ndi filimu ya polypropylene yopangidwa ndi njira yopangira tepi.Ikhozanso kugawidwa mu CPP wamba ndi kuphika CPP.Ili ndi kuwonekera bwino kwambiri, makulidwe ofanana, komanso magwiridwe antchito ofanana molunjika komanso mopingasa.Nthawi zambiri amagwiritsidwa ntchito ngati gawo lamkati la filimu yophatikizika.

CPP (Cast Polypropylene) ndi filimu ya polypropylene (PP) yopangidwa ndi cast extrusion process mumakampani apulasitiki.Ntchito: Amagwiritsidwa ntchito kwambiri ngati wosanjikiza wamkati wosindikiza wakompositi filimu, oyenera kulongedza mafuta okhala ndi zinthu komanso zopinga kuphika.

3. Biaxially oriented polypropylene film

Biaxially oriented polypropylene filimu amapangidwa ndi co extruding polypropylene particles kukhala mapepala, ndiyeno kutambasula mu njira zonse ofukula ndi yopingasa.

Ntchito: 1. Amagwiritsidwa ntchito makamakakompositi filimukusindikiza pamwamba.2. Ikhoza kupangidwa kukhala filimu ya pearlescent (OPPD), filimu yowonongeka (OPPZ), ndi zina pambuyo pokonza mwapadera.

4. Chlorinated polyethylene (CPE)

Chlorinated polyethylene (CPE) ndi zinthu za polima zodzaza ndi mawonekedwe a ufa woyera, zopanda poizoni komanso zopanda kukoma.Ili ndi kukana kwanyengo kwabwino kwambiri, kukana kwa ozoni, kukana kwa mankhwala komanso kukana kukalamba, komanso kukana kwamafuta abwino, kutha kwa lawi lamoto komanso kupanga utoto.

5. Kanema wa nayiloni (ONY)

Filimu ya nayiloni ndi filimu yolimba kwambiri yowonekera bwino, yonyezimira bwino, kulimba kwamphamvu kwambiri, kulimba kwamphamvu kwambiri, kukana kutentha, kukana kuzizira, kukana mafuta ndi kukana zosungunulira za organic, kukana bwino kwa abrasion, kukana kuphulika, komanso kufewa, kukana mpweya wabwino; koma ili ndi ntchito yolepheretsa nthunzi yamadzi, kuyamwa kwa chinyezi, kutsekemera kwachinyontho, koyenera kulongedza zinthu zolimba, monga zakudya zamafuta Zakudya za nyama, zakudya zokazinga, zakudya zovundikira, kuphika chakudya etc.

Ntchito: 1. Amagwiritsidwa ntchito makamaka pamtundu wapamwamba komanso wapakatikati wa membrane wamagulu.2. Kupaka zakudya zamafuta, zoyikapo zoziziritsa kukhosi, kulongedza vacuum, kuphika zotsekera zotsekereza.

6. Filimu ya polyester (PET)

Filimu ya poliyesitala imapangidwa ndi polyethylene terephthalate ngati zopangira, zomwe zimatulutsidwa m'mapepala okhuthala ndikutambasulidwa biaxially.

Komabe, mtengo wa filimu ya poliyesitala ndi wokwera kwambiri, wokhala ndi makulidwe ambiri a 12mm.Nthawi zambiri amagwiritsidwa ntchito ngati zinthu zakunja zopangira zophikira, ndipo zimakhala ndi zosindikiza zabwino.

Mapulogalamu: 1. Zophatikizika zamakanema osindikizira pamwamba;2. Ikhoza kukhala aluminized.

7. AL (zojambula za aluminiyamu)

Aluminiyamu zojambulazo ndi mtundu wa zinthu zonyamulazomwe sizinasinthidwebe.Ndi bwino kutentha conductor ndi sunshade.

8. Kanema wa aluminized

Pakalipano, mafilimu opangidwa ndi aluminiyamu omwe amagwiritsidwa ntchito kwambiri makamaka amaphatikizapo filimu ya polyester aluminized (VMPET) ndi CPP aluminized film (VMCPP).Mafilimu opangidwa ndi aluminiyamu ali ndi mawonekedwe a filimu yapulasitiki ndi zitsulo.Udindo wa zokutira zotayidwa pa filimu pamwamba ndi kutsekereza kuwala ndi kupewa cheza ultraviolet, amene osati kumangowonjezera alumali moyo wa nkhani, komanso bwino kuwala kwa filimuyo.Pamlingo wina, imalowa m'malo mwa zojambulazo za aluminiyamu, komanso imakhala yotsika mtengo, yokongola komanso yotchinga bwino.Chifukwa chake, zokutira za aluminiyamu zimagwiritsidwa ntchito kwambiri pakuyika zophatikizika, zomwe zimagwiritsidwa ntchito kwambiri pamapaketi akunja azakudya zouma komanso zodzitukumula monga mabisiketi.
