Kubalulekile ukuba uqaphele ukuba xa uvula iifayile ze-PET, kufuneka uthathe izilumkiso kwaye ube nezixhobo ezihlaziyiweyo nezithembekileyo ukuphepha nayiphi na ingozi yokhuseleko. Ngaphaya koko, kuyacetyiswa ukwazi iimpawu kunye nokusebenza kweenkqubo eziza kusetyenziswa, kunye nokuhambelana kwazo inkqubo yokusebenza isetyenziswa.

Njengoko iteknoloji iqhubela phambili, iindlela ezintsha kunye nezixhobo zokuvula iifayile ze-PET zinokuthi zivele. Ke ngoko, kubalulekile ukuba uhlale unolwazi ngohlaziyo lwamva nje kunye nezixhobo ezikhoyo zokwandisa le nkqubo.

Ngamafutshane, ngolwazi oluchanekileyo kunye nezixhobo, ukuvula ifayile ye-PET ingaba yinkqubo ekhawulezayo nesebenzayo. Ukwenza uninzi lwezi fayile kuya kuvumela abasebenzisi ukuba bafikelele kumxholo kwaye banandiphe izibonelelo abanikezela ngazo. Nangona kunjalo, masihlale sikhumbula ukuhlala sinolwazi, sihlaziywa kwaye sikhuselwe amava etekhnoloji awonelisayo.
