Zinthu zowonongeka ndi pulasitiki yomwe mawonekedwe ake amadzimadzi amasintha kumalo enaake omwe amachititsa kuti ntchito iwonongeke mkati mwa nthawi inayake.Zowonongeka zoyikapo pulasitiki zili ndi ntchito komanso mawonekedwe apulasitiki achikhalidwe.Kupyolera mu zochita za kuwala kwa ultraviolet kapena tizilombo toyambitsa matenda a nthaka ndi madzi, kugawanika, kuwonongeka ndi kuchepetsa, ndipo potsirizira pake kulowanso m'chilengedwe m'malo opanda poizoni ndikubwerera ku chilengedwe.
Zomwe zimapangidwira pamapepala zimakhala ndi ulusi wachilengedwe wachilengedwe, womwe umawola mwachangu m'chilengedwe, sudzawononga chilengedwe, ndipo ukhoza kusinthidwanso kukhala pepala.Choncho, nthawi zonse takhala tikuthandizira cholinga cha chitetezo cha chilengedwe chobiriwira, kuti tikhazikitse bwino chithunzithunzi chamakampani, kuti tibwererenso ku chikhalidwe cha chilengedwe.Zamkati akamaumba mankhwala kuwonjezera kuwala kuwala, zotchipa, mantha ndi ubwino zina alinso ndi mpweya permeability, zothandiza kuteteza katundu watsopano, mu kufalitsidwa katundu padziko lonse, chimagwiritsidwa ntchito mazira, zipatso, magalasi mankhwala ndi zina zosalimba, osalimba, akuwopa kulongedza katundu wa extrusion.
Kugwiritsa ntchito mabokosi opanda vuto ndi matumba ndi njira yathu.European Packaging and Packaging Waste Directive imati milingo yazitsulo zolemera ( lead, mercury, aluminium, etc.) ndi milingo ya lead ikhale yosakwana 100PPM.Mayiko ayenera yoletsedwa mu mawonekedwe a malamulo ntchito kapena kuchepetsa ntchito zina munali kutsogolera, mercury kapena zotayidwa ndi zigawo zina zoipa za ma CD zipangizo, ndi heavy metal zili, pa msika ndi wotchuka kwambiri disposable thovu nkhomaliro bokosi komanso osati akhoza osati zobwezerezedwanso, ndi kukwiriridwa mobisa kwa nthawi yaitali, kuwotcha ndi kuchititsa kuipitsidwa kwa chilengedwe, choncho ayenera yoletsedwa.Chifukwa chake kuyika mapepala mosasamala kanthu komwe kumachokera, poyerekeza ndi zinthu zina zonyamula, bokosi loyika mapepala ndi thumba la pepala ndizosankha bwino.
