Amathreyi e- CPET , noma amathreyi e-Crystalline Polyethylene Terephthalate, awuhlobo lokupakisha ukudla okwenziwe ngohlobo oluthile lwezinto ze-thermoplastic. CPET yaziwa ngokumelana kwayo okuhle kakhulu namazinga okushisa aphezulu naphansi, okwenza kube ukukhetha okuthandwayo kwezicelo ezahlukene zokupakisha ukudla.

Yebo , amathreyi epulasitiki angu CPET angafakwa kuhhavini. Angamelana namazinga okushisa asukela ku--40°C kuya ku-220°C (-40°F kuya ku-428°F), okuvumela ukuthi asetshenziswe kumahhavini e-microwave, kumahhavini avamile, ngisho nasendaweni yokugcina eqandisiwe.

Umehluko omkhulu phakathi kwamathileyi e- CPET namathileyi e-PP (Polypropylene) ukumelana kwawo nokushisa kanye nezakhiwo zezinto ezibonakalayo. Amathileyi CPET amelana nokushisa kakhulu futhi angasetshenziswa kokubili kuma-microwave kanye nama-oven avamile, kuyilapho amathileyi e-PP evame ukusetshenziselwa izinhlelo zokusebenza ze-microwave noma indawo yokugcina ebanda. CPET inikeza ukuqina okungcono kanye nokumelana nokuqhekeka, kanti amathileyi e-PP aguquguquka kakhulu futhi ngezinye izikhathi angabiza kancane.

Amathileyi e- CPET asetshenziselwa izinhlelo ezahlukene zokupakisha ukudla, okuhlanganisa ukudla okulungele, imikhiqizo yokubhaka, ukudla okuqandisiwe, nezinye izinto ezibolayo ezidinga ukufudunyezwa kabusha noma ukupheka kuhhavini noma kuma-microwave.

I- CPET kanye ne- PET zombili ziyizinhlobo zama-polyester, kodwa zinezakhiwo ezihlukile ngenxa yezakhiwo zazo zama-molecule. CPET iwuhlobo lwe-crystalline lwe- PET , olunikeza ukuqina okwandisiwe kanye nokumelana okungcono namazinga okushisa aphezulu naphansi. PET ivame ukusetshenziselwa amabhodlela eziphuzo, izitsha zokudla, kanye nezinye izinhlelo zokusebenza zokupakisha ezingadingi izinga elifanayo lokubekezelela amazinga okushisa. PET isobala kakhulu, kuyilapho CPET ivame ukungacaci noma ingabonakali kangako.
