ʻO nā pā CPET, a i ʻole nā ​​pā Crystalline Polyethylene Terephthalate, he ʻano ʻōpala meaʻai i hana ʻia mai kahi ʻano mea thermoplastic. Ua kaulana ʻo CPET no kona kūpaʻa maikaʻi loa i nā mahana kiʻekiʻe a me ka haʻahaʻa, e lilo ia i koho kaulana no nā noi ʻōpala meaʻai like ʻole.

ʻAe , hiki ke hoʻomehana ʻia nā pā palaki CPET i loko o ka umu. Hiki iā lākou ke kū i nā mahana mai -40°C a i 220°C (-40°F a i 428°F), kahi e hiki ai ke hoʻohana ʻia i loko o nā umu microwave, nā umu maʻamau, a me ka mālama ʻana i loko o ka hau.

ʻO ka ʻokoʻa nui ma waena o nā pā CPET a me nā pā PP (Polypropylene) ʻo ko lākou kūpaʻa wela a me nā waiwai o nā mea. ʻOi aku ka kūpaʻa o nā pā CPET i ka wela a hiki ke hoʻohana ʻia i loko o nā umu microwave a me nā umu maʻamau, ʻoiai ʻo nā pā PP e hoʻohana pinepine ʻia no nā noi microwave a i ʻole ka mālama anu. Hāʻawi ʻo CPET i ka paʻakikī a me ke kūpaʻa i ka haki ʻana, ʻoiai ʻoi aku ka maʻalahi o nā pā PP a hiki ke emi ke kumukūʻai i kekahi manawa.

. Hoʻohana ʻia nā pā CPET no nā noi hoʻopili meaʻai like ʻole, me nā meaʻai mākaukau, nā huahana bakery, nā meaʻai hau, a me nā mea ʻē aʻe e pono ai ke hoʻomehana hou a kuke paha i loko o ka umu a i ʻole ka microwave

ʻO CPET a me PET nā ʻano polyester ʻelua, akā he ʻokoʻa ko lākou mau waiwai ma muli o ko lākou mau ʻano molekala. ʻO CPET kahi ʻano crystalline o PET, kahi e hāʻawi ai iā ia i ka paʻakikī a me ke kūpaʻa maikaʻi i nā mahana kiʻekiʻe a me nā mahana haʻahaʻa. Hoʻohana pinepine ʻia ʻo PET no nā ʻōmole inu, nā ipu meaʻai, a me nā noi hoʻopili ʻē aʻe ʻaʻole pono ke ʻano like o ka hoʻomanawanui mahana. ʻOi aku ka moakaka o PET, ʻoiai ʻo CPET he opaque a semi-transparent paha.
