Amathileyi we-CPT, noma ama-crystalline polyethylene terephthalate tress, uhlobo lokupakishwa kokudla okwenziwe ngohlobo oluthile lwezinto ezibonakalayo ze-thermoplastic. I-CPET yaziwa ngokumelana kwayo okuhle kakhulu kumazinga okushisa aphezulu futhi aphansi, okwenza kube ukukhetha okuthandwayo kwezicelo ezahlukahlukene zokupakisha zokudla.

Amathileyi epulasitiki yebo, ama-ccep akweqile. Bangakwazi ukubekezelela amazinga okushisa asuka ku-40 ° C kuya ku-220 ° C (-40 ° F kuya ku-428 ° F), okubavumela ukuthi basetshenziswe ku-Ovens microwave, ama-oveni ajwayelekile, kanye nesitoreji esibandayo.

Umehluko omkhulu phakathi kwamathreyi we-CPET kanye ne-PP (Polypropylene) amathreyi awo ukumelana nokushisa kwawo kanye nezinto ezibonakalayo. Amathoyimitha we-CPES amelana nokushisa futhi angasetshenziswa kuwo wonke ama-microwave kanye nama-oveni ajwayelekile, ngenkathi amathimu we-PP asetshenziselwa izinhlelo ze-microwave noma isitoreji esibandayo. I-CPET inikeza ukuqina okungcono nokumelana nokuqhekeka, kanti amathremu e-PP avumelana nezimo futhi kwesinye isikhathi angenza kubize kakhulu.

Amathileyi we-CPT asetshenziselwa izinhlelo ezahlukahlukene zokupakisha zokudla, kufaka phakathi ukudla okulungele, imikhiqizo yokubhaka, ukudla okuqandisiwe, nezinye izinto ezibonakalayo ezidinga ukusheshiswa noma ukupheka kuhhavini noma nge-microwave.

I -CPET nesilwane esifuywayo yizo zombili izinhlobo ze-polyesters, kepha zinezakhiwo ezihlukile ngenxa yezinhlaka zazo ze-molecular. I-CPET yifomu le-crystalline yesilwane, elinikeza ukwanda kokuqina nokumelana kangcono namazinga okushisa aphezulu aphansi. I-Pet imvamisa isetshenziselwa amabhodlela okuphuza, iziqukathi zokudla, nezinye izinhlelo zokupakisha ezingadingi isilinganiso esifanayo sokubekezelela kwezinga lokushisa. UPet ubonakala ngokwengeziwe, kanti i-CPET imvamisa i-Opaque noma esobala.
