Ko ngā paepae CPET, ko ngā paepae Crystalline Polyethylene Terephthalate rānei, he momo takai kai i hangaia mai i tētahi momo rauemi thermoplastic motuhake. E mōhiotia ana te CPET mō tōna ātete pai ki ngā pāmahana teitei me te pāmahana iti, ā, he mea rongonui mō ngā momo tono takai kai.

Āe , ka taea te tunu i ngā paepae kirihou CPET ki te oumu. Ka taea e rātou te tu atu i ngā pāmahana mai i te -40°C ki te 220°C (-40°F ki te 428°F), e āhei ai te whakamahi i roto i ngā oumu ngaruiti, ngā oumu tikanga, tae atu ki te rokiroki tio.

Ko te rerekētanga matua i waenga i ngā paepae CPET me ngā paepae PP (Polypropylene) ko tō rātou ātete wera me ngā āhuatanga rauemi. He ātete wera ake ngā paepae CPET, ā, ka taea te whakamahi i roto i ngā oumu ngaruiti me ngā oumu tuku iho, ko ngā paepae PP ia e whakamahia ana mō ngā mahi ngaruiti, mō te rokiroki matao rānei. He pakari ake te CPET me te ātete ki te pakaru, engari he ngāwari ake ngā paepae PP, ā, i ētahi wā he iti ake te utu.

. Ka whakamahia ngā paepae CPET mō ngā momo tono tākai kai, tae atu ki ngā kai kua oti te whakarite, ngā hua tunutunu, ngā kai tio, me ētahi atu taonga pirau e hiahia ana kia whakamahanahia, kia tunua rānei i roto i te oumu, i te ngaruiti rānei

He momo polyesters te CPET me te PET, engari he rerekē ngā āhuatanga o rāua nā ō rāua hanganga ngota. He momo PET tioata te CPET, e whakapiki ana i tōna pakari me te ātete pai ake ki ngā pāmahana teitei me ngā pāmahana iti. Ko te PET te mea e whakamahia ana mō ngā pounamu inu, ngā ipu kai, me ētahi atu tono tākai kāore e hiahia ana ki te taumata ōrite o te manawanui pāmahana. He mārama ake te PET, ko te CPET ia he pōuri, he āhua mārama rānei.
