Kodi mapepala apulasitiki omwe amagwiritsidwa ntchito kwambiri popaka matuza ndi ati?Kodi matuza packaging ndi chiyani?

Zomwe zimagwiritsidwa ntchito kwambiri ndi mapepala apulasitikimatuza phukusi?Kodi matuza packaging ndi chiyani?
Mapepala omwe amagwiritsidwa ntchito popanga matuza amatchedwa pepala lolimba kapena filimu, yomwe imagwiritsidwa ntchito kwambiri ndi: pet (polyethylene terephthalate) pepala lolimba, pvc (polyvinyl chloride) pepala lolimba, ps (polystyrene) pepala lolimba.Tsamba lolimba la PS limakhala ndi kachulukidwe kakang'ono, losalimba bwino, losavuta kuwotcha, ndipo limatulutsa mpweya wa styrene (chinthu choyipa) likayaka, motero limagwiritsidwa ntchito popanga matayala apulasitiki amitundu yosiyanasiyana.Pepala lolimba la pvc lili ndi kulimba kwapakatikati ndipo silosavuta kuwotcha.Ikayaka, imapanga haidrojeni, yomwe idzakhudza chilengedwe.pvc ndiyosavuta kutentha ndi kusindikiza, ndipo imatha kukulungidwa ndi makina osindikizira komanso makina othamanga kwambiri.Ndizofunika kwambiri zopangira zinthu zapulasitiki zowonekera.Pepala lolimba la pet limakhala ndi kulimba kwabwino, kutanthauzira kwakukulu, kosavuta kuwotcha, ndipo silitulutsa zinthu zovulaza likayaka.Ndizinthu zowononga chilengedwe, koma mtengo wake ndi wokwera, ndipo ndi woyenera kupangira matuza apamwamba kwambiri.Komabe, sikophweka kutentha chisindikizo, zomwe zimabweretsa zovuta kwambiri pakuyika.Kuti tithetse vutoli, timaphatikiza filimu ya pvc pamwamba pa pet, yomwe imatchedwa petg hard film, koma mtengo wake ndi wapamwamba.
Kodi matuza packaging ndi chiyani?Ndi chiyani chomwe chiyenera kutsatiridwa pakuyika makadi a blister?
Kupaka matuza kumatanthawuza kutentha kusindikiza chithuza pamwamba pa khadi la pepala lomwe lili ndi mafuta a chithuza, omwe amagwiritsidwa ntchito popanga batire wamba m'misika.Chikhalidwe chake ndi chakuti mankhwalawa ayenera kusindikizidwa pakati pa khadi la pepala ndi blister.Mavuto omwe ayenera kuzindikiridwa ndi awa: 1. Zimatanthawuza kuti pamwamba pa khadi la pepala liyenera kuphimbidwa ndi mafuta apulasitiki (kuti athe kutenthedwa ndi chipolopolo cha pvc bubble);2. Chipolopolo cha bubble chikhoza kupangidwa ndi pvc kapena mapepala a petg;3. Popeza chipolopolo cha kuwira chimangokhala chomata Pamwamba pa khadi la pepala, kotero kuti katundu wa mmatumba samakonda kunenepa kwambiri.
