Iitreyi ze-ctch, okanye i-crystalline Polythylene Terephthane Trays, luhlobo lwepakethi yokutya okwenziwe kuhlobo oluthile lwezinto ezithile zeTROPICT. I-CEBE yaziwa ngokuchasene nokuchasana nokuchasana neqondo eliphakamileyo neliphantsi, lisenza ukhetho oluqhelekileyo kwizicelo zokupakishwa kokutya.

A Ewe, iitreyitha zeplastiki zeplanethi ze-CPE, ze-cpet ziyinyani. Banokukhulisa amaqondo obushushu asusela--40 ° C ukuya kwi-220 ° C (-40 ° F ukuya kwi-428 ° F), ebavumela ukuba basetyenziswe kwi-microwave ovens, i-oveni eqhelekileyo, kunye nokugcina i-rose.

Umahluko ophambili phakathi kweetreyi ze-ctch kunye ne-PP (POLYPROPLY) Iitreyitha zeChis zixhaphake ngakumbi ubushushu kwaye zinokusetyenziswa kuzo zombini i-microwave kunye nee-oveni eziqhelekileyo, ngelixa iitreyi ze-PP zihlala zisetyenziselwa izicelo ze-microwave okanye ukugcinwa kubanda. I-cgne inikezela ngobuqhetseba obungcono kunye nokuchasana nokucutha, kanti iitreyi ze-PP ziguquguquka ngakumbi kwaye ngamanye amaxesha zingabizi kakhulu.

Iitreyitha ze-cpey zisetyenziselwa ukupakishwa kwezicelo ezahlukeneyo zokutya, kubandakanya ukutya okubekiweyo, iimveliso zokubhaka, ukutya okuthambileyo, kunye nezinye izinto ezonakalayo ezifuna ukuhlaziya okanye ukupheka kwi-oveni okanye kwi-microwave.

I -cggy kunye nesilwanyana sasekhaya zizo zombini iintlobo ze-polysters, kodwa zinepropathi eyahlukileyo ngenxa yezakhiwo zabo zemolekyuli. I-CHETO ikwindlela ye-crystalline yesilwanyana sasekhaya, enika i-gigality eyongezelelweyo kunye nokuchasana nokuchasana nobushushu obuphezulu nobusezantsi. Isilwanyana sasekhaya sisetyenziselwa iibhotile zesiselo, izikhongozelo zokutya, kunye nezinye izicelo zokupakisha ezingafuni umgangatho ofanayo wokunyamezelana kobushushu. Isilwanyana sasekhaya sibonakale ngakumbi, ngelixa i-cgnet ihlala i-opaque okanye ifihlakele.
