Impahla yelebula ye-PET enamathelayo ekwazi ukumelana nokushisa okuphezulu iwumsebenzi welebula oklanyelwe imikhiqizo enezidingo zokusebenza kwendawo yokushisa ephezulu. Umbala wezinto ezingaphezulu usobala, umhlophe okhanyayo, omhlophe, isiliva lase-Asia, isiliva elikhanyayo nezinye izinto, ezinokumelana okuhle kakhulu kwezinyembezi, ukumelana nokushisa okuphezulu, ukumelana nokukhanya kanye nokumelana nokugqwala kwamakhemikhali, ngenxa yokusetshenziswa kwezinto ze-PET, eziphakeme kakhulu. ukumelana nokushisa, kungamelana nokusebenza kwezimboni kanye nenqubo yokushisa endaweni yokushisa ephezulu, akulula ukukhubaza noma ukufiphala. Le nto yelebula ifanelekela imikhiqizo edinga ukumelana nokushisa okuphezulu, njengezingxenye zezimoto, izingxenye ze-elekthronikhi, izinto zikagesi, njll. Ngokusetshenziswa kwezinto zelebula ze-PET actoadhesive ezimelana nokushisa okuphezulu, umkhiqizo ungabonakala ngokucacile, uzinze futhi uthembekile ngaphansi kokushisa okuphezulu. izimo zokushisa, ukuthuthukisa ukwethembeka nokulandeleka komkhiqizo, futhi inikeze ukwesekwa okuqinile kokukhiqizwa nokusetshenziswa kwemikhiqizo. Inkampani yaseDonglai ikakhulukazi ikhiqiza ingcina ye-PVC, ingcina ye-BOPP, ingcina ye-PE, ingcina ye-PET, iphepha elishisayo, iphepha lokubhala, iphepha elihlanganisiwe nezinye izinto ezingasetshenzisiwe.
