Kusintha kwa polypropylene: matumba a PP, matumba a BOPP ndi matumba amatsegula njira zothetsera ma CD okhazikika

Pomwe kufunikira kwapadziko lonse kwapadziko lonse lapansi kwazinthu zokhazikika kukukulirakulira, makampani akutembenukira kunjira zina zatsopano monga matumba oluka a PP, matumba a BOPP, ndi matumba olokedwa.Mayankho ophatikizika awa samangopereka ma CD amphamvu komanso odalirika, komanso amathandizira kwambiri kuchepetsa zinyalala za pulasitiki ndi carbon footprint.Tiyeni tiwone mozama za mawonekedwe, maubwino ndi kukhazikika kwa mayankho pamapaketiwa.

Kusinthasintha komanso kulimba kwa matumba oluka a PP:
Matumba opangidwa ndi PP, omwe amadziwikanso kuti matumba a polypropylene, ndi otchuka chifukwa cha kulimba kwawo, zosankha zambiri, komanso kugwiritsa ntchito zinthu zosiyanasiyana.Matumbawa amapangidwa pogwiritsa ntchito ulusi wolukidwa wopangidwa ndi ulusi wa polypropylene, zomwe zimapangitsa kuti pakhale njira yolumikizira yolimba komanso yolimba.Matumba opangidwa ndi PP ali ndi maubwino ambiri, kuphatikiza kukana chinyezi, chitetezo cha UV komanso kutha kunyamula katundu wolemera, kuwapangitsa kukhala abwino kulongedza zinthu zosiyanasiyana, kuchokera ku zokolola zaulimi kupita kuzinthu zomangira komanso zotengera zosiyanasiyana za ogula.

Matumba a BOPP: tsogolo la ma CD osinthika:
Matumba a Biaxially oriented polypropylene (BOPP) akhala akusintha masewera pamakampani osinthira ma CD.Matumbawa amapangidwa ndikuyala filimu yopyapyala ya BOPP kupita ku gawo lapansi lopangidwa ndi polypropylene.Kuphatikizika kwa nsalu yolimba yoluka ndi wosanjikiza woonda wa BOPP kumawonjezera mphamvu m'thumba komanso kumapereka kusindikiza kwabwino komanso kukongola kowoneka bwino.Matumba a BOPP ali ndi ntchito zofunika pamakampani azakudya chifukwa amawonetsetsa kutsitsimuka kwazinthu, amapereka chotchinga ku chinyezi ndi fungo, ndipo amapezeka m'miyeso ndi mapangidwe osiyanasiyana kuti agwirizane ndi zofunikira zonyamula katundu.

Kuwonjezeka kwa matumba opangidwa:
Matumba olukidwa amapangidwanso ndi zinthu za polypropylene, zomwe zalandira chidwi kwambiri m'zaka zaposachedwa chifukwa cha mawonekedwe ake zachilengedwe komanso kukonzanso kosavuta.Zopangidwa ndi zomangamanga zowongoka kwambiri, matumbawa ndi abwino kulongedza katundu wolemera.Matumba olukidwa amagwiritsidwa ntchito kwambiri kulongedza zinthu monga mbewu, feteleza, simenti ndi zinthu zina zomangira.Mphamvu zawo zolimba kwambiri, kukana misozi ndi kukana chinyezi zimawapangitsa kukhala njira yodalirika komanso yotsika mtengo yopangira ma phukusi.

Kukhazikika komanso kukonda zachilengedwe:
Chimodzi mwazifukwa zazikulu zomwe zikuchulukirachulukira kuchulukira kwa mayankho amapaketiwa ndi zotsatira zake zabwino pa chilengedwe.Matumba opangidwa ndi PP, matumba a BOPP, matumba oluka onse amatha kubwezeretsedwanso, omwe amathandizira kuchepetsa zinyalala zapulasitiki komanso kulimbikitsa machitidwe azachuma ozungulira.Kuphatikiza apo, kupanga ma CD a polypropylene kumafuna mphamvu zochepa kwambiri kuposa njira zamapulasitiki zachikhalidwe, kuchepetsa kuchuluka kwa mpweya.Mayankho opakira awa akhala njira yotheka, yobiriwira pomwe makampani amakumbatira kukhazikika komanso kuyanjana ndi chilengedwe.

Pomaliza:
Kufunika kwa ma CD okhazikika kukuchulukirachulukira ndipo makampaniwa akuwona kusintha komwe kukuchulukirachulukira kwa zikwama zoluka za PP, matumba a BOPP ndi zikwama zoluka.Mayankho amapaketiwa amapereka kukhazikika, zosankha zosinthika komanso kusindikiza kwabwino kwambiri, pomwe akupita patsogolo kwambiri pakuchepetsa zinyalala za pulasitiki ndi mpweya wa carbon.Kusinthasintha komanso kuyanjana kwachilengedwe kwa mayankho amapaketiwa kumathandizira kukonza tsogolo lobiriwira, lokhazikika pomwe makampani amazindikira kufunikira kwa machitidwe okhazikika.
