Pakadali pano,zinthu zodzikongoletsera zowola zomwe zimatha kuwolaakhala akugwiritsidwa ntchito popaka mafuta odzola, milomo ndi zodzola zina zolimba. Chifukwa cha mawonekedwe apadera a zodzoladzola, sizimangofunika kukhala ndi mawonekedwe apadera, komanso zimafunika kukhala ndi phukusi lomwe limakwaniritsa ntchito zake zapadera.
Mwachitsanzo, kusakhazikika kwa zinthu zopangira zodzikongoletsera kuli pafupi ndi chakudya. Chifukwa chake, kulongedza zodzikongoletsera kuyenera kupereka zinthu zotchinga bwino komanso zoteteza pamene zikusunga zinthu zokongoletsera. Kumbali imodzi, ndikofunikira kupatula kuwala ndi mpweya kwathunthu, kupewa kukhuthala kwa zinthu, ndikulekanitsa mabakiteriya ndi tizilombo tina kuti tisalowe muzinthuzo. Kumbali ina, ziyeneranso kuletsa zosakaniza zogwira ntchito mu zodzoladzola kuti zisalowe ndi zinthu zopangira kapena kuyanjana nazo panthawi yosungira, zomwe zidzakhudza chitetezo ndi ubwino wa zodzoladzola.
Kuphatikiza apo, ma CD okongoletsera ali ndi zofunikira kwambiri pa chitetezo cha zamoyo, chifukwa mu zowonjezera za ma CD okongoletsera, zinthu zina zovulaza zimatha kusungunuka ndi zodzoladzola, zomwe zimapangitsa kuti zodzoladzola ziipitsidwe.
Zipangizo zophikira zodzikongoletsera zomwe zimatha kuwola:
Zinthu za PLAIli ndi makina opangidwa bwino komanso imagwirizana bwino ndi zinthu zina, ndipo pakadali pano ndiye chinthu chachikulu chomwe chimaphikidwa mosavuta pa zodzoladzola. Zipangizo za PLA zili ndi kulimba bwino komanso kukana makina, zomwe zimapangitsa kuti ikhale yabwino kwambiri popangira zodzoladzola zolimba.
Cellulose ndi zotumphukira zakeNdi ma polysaccharide omwe amagwiritsidwa ntchito kwambiri popanga ma paketi ndipo ndi ma polima achilengedwe ambiri padziko lonse lapansi. Amakhala ndi mayunitsi a glucose monomer olumikizidwa pamodzi ndi ma bond a B-1,4 glycosidic, omwe amalola ma cellulose chains kupanga ma bond amphamvu a hydrogen interchain. Ma cellulose packaging ndi oyenera kusungira zodzoladzola zouma zomwe sizili ndi hygroscopic.
Zinthu zosakaniza ndi sitachiNdi ma polysaccharide opangidwa ndi amylose ndi amylopectin, makamaka ochokera ku chimanga, chinangwa ndi mbatata. Zipangizo zopangidwa ndi starch zomwe zimapezeka m'masitolo zimakhala ndi chisakanizo cha starch ndi ma polima ena, monga polyvinyl alcohol kapena polycaprolactone. Zipangizo zopangidwa ndi starch izi zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana zimagwiritsidwa ntchito m'mafakitale osiyanasiyana ndipo zimatha kukwaniritsa zofunikira pakuyika extrusion, kupanga jakisoni, kupanga blow molding, kupukuta filimu ndi kutulutsa thovu la ma CD okongoletsera. Zoyenera kupakidwa zodzoladzola zouma zopanda hygroscopic.
Chitosanili ndi mphamvu yogwiritsira ntchito zinthu zodzoladzola zomwe zimatha kuwola chifukwa cha mphamvu yake yolimbana ndi mavairasi. Chitosan ndi polysaccharide ya cationic yomwe imachokera ku deacetylation ya chitin, yomwe imachokera ku zipolopolo za crustacean kapena fungal hyphae. Chitosan ingagwiritsidwe ntchito ngati chophimba pa mafilimu a PLA kuti ipange ma phukusi osinthika omwe amatha kuwola komanso oletsa antioxidant.
