Babu wani bambanci tsakanin PET da APET filastik. PET shine polyester, wanda ke da sunan sunadarai na polyethylene terephthalate. Ana iya yin PET tare da polymers masu daidaitawa ta hanyoyi biyu na farko; amorphous ko crystalline. Kusan, duk abin da kuke hulɗa da shi amorphous ne tare da babban banbanci ɗaya; trays na abinci na microwave waɗanda, idan an yi su daga PET, ana yin su daga C-PET (crystallized PET). Ainihin duk bayyananniyar PET ciki har da Mylar da kwalabe na ruwa an yi su ne daga A-PET (amorphous PET) kuma a yawancin lokuta, “A” ana barin sa kawai.

Alamar sake amfani da madaidaicin Mobius don polyester shine PET tare da lamba 1, don haka mutane da yawa suna kiran polyester a matsayin PET. Wasu sun fi son zama takamaiman, ta hanyar nuna ko polyester shine C-PET crystalline, amorphous APET, RPET da aka sake yin amfani da shi, ko PETG glycol da aka gyara. Waɗannan ƙananan bambance -bambancen ne, waɗanda aka yi niyya don sauƙaƙe sarrafa polyester don ƙarshen samfurin da aka yi niyya, ko ta hanyar yin allura, gyare -gyaren busawa, thermoforming, ko fitarwa har ma da kammala ayyukan kamar yankewar mutuwa.

PETG yana zuwa tare da mafi girman farashin farashi kuma yana da sauƙin mutuwa a yanke fiye da APET ta amfani da kayan yankan mutuwa na al'ada. A lokaci guda, shi ma ya fi taushi kuma ya fi sauƙi fiye da APET. Masu juyawa waɗanda ba su da kayan aikin da suka dace don mutuwa yanke APET galibi suna aiki tare da PETG saboda gaskiyar cewa PETG ya fi taushi kuma ya fi sauƙi, don haka galibi yana rufe fuska (wannan shine siririn “Saran kunsa”).
