Impahla yelebula ye-PET enamathelayo ekwazi ukumelana nokushisa okuphezulu iwumsebenzi welebula oklanyelwe imikhiqizo enezidingo zokusebenza kwendawo yokushisa ephezulu. Umbala wezinto ezibonakalayo 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, ezinokumelana okuhle kakhulu nokushisa okuphezulu, kungamelana nokusebenza kwezimboni kanye nenqubo yokushisa endaweni yokushisa ephezulu, akulula ukuyicisha noma ukufiphala. Le nto yelebula ifanele imikhiqizo edinga ukumelana nokushisa okuphezulu, njengezingxenye zezimoto, izingxenye ze-elekthronikhi, izinto zikagesi, njll. Ngokusetshenziswa kwezinto zelebula ye-PET actoadhesive ekwazi ukumelana nokushisa okuphezulu, umkhiqizo ungabonakala ngokucacile, uzinzile futhi uthembekile ngaphansi kwezimo zokushisa okuphezulu, ukuthuthukisa ukuthembeka nokulandeleka komkhiqizo, futhi unikeze ukusekela okuqinile ekukhiqizeni nasekusetshenzisweni 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.
