Chingwe cha PET (chingwe cha poliyesitala) chimakhala ndi moyo wosungira bwino wa miyezi 18-36 pansi pamikhalidwe yoyenera. Kutentha, chinyezi, kuwonekera kwa UV, ndi kukhulupirika kwa phukusi zonse zimakhudza kutalika kwa chingwe cha PET.

Miyezo yapakati ndi zina mwazomwe zimanyalanyazidwa kwambiri pamene ogula amasankha lamba la PET (chingwe cha poliyesitala) kuti azingomanga basi. Chingwe chomwe chimakwaniritsa zofunikira zonse zamakina - m'lifupi mwake, makulidwe ake, ndi mphamvu yosweka - chidzayambitsabe mavuto odyetsa ngati kukula kwake sikufanana ndi choperekera mutu. M'kati mwake, m'lifupi mwake, m'lifupi mwake, ndi mpukutu wakunja kwake zonse ziyenera kugwirizana ndi makina opikira ndi kupumula. Bukuli likufotokoza kukula kwa zingwe za PET, momwe zimakhudzira magwiridwe antchito amutu, komanso momwe mungatsimikizire kuti zimagwirizana musanagule.

Kulimba kwamphamvu kwa chingwe cha PET nthawi zambiri kumachokera ku 160 mpaka 635 kilogalamu, kutengera kukula kwake komanso mtundu wake wopanga. Kuyeza uku kumayimira mphamvu yayikulu yomwe chingwe cha polyethylene terephthalate chingapirire chisanathyoke, ndikupangitsa kukhala chinthu chofunikira kwambiri pakugula mana.

Kufananiza lamba la PET kumakina anu ongomanga okha kumafuna chidwi ndi m'lifupi, makulidwe, kukula kwapakati, ndi kumapeto kwa pamwamba. Bukuli likuphatikiza zinthu zazikulu zofananira, zovuta zomwe wamba, ndi maupangiri osankha kuti zitsimikizire kuti zikuyenda bwino komanso chitetezo chodalirika cha katundu.
