Iiikomityi zeplastiki ezilahlwayozikholisa ukwenziwa ukusukaPolyethylene terephthalate (PET okanye PETE), iPolypropylene(PP) kunye nePolystyrene(PS).Zonke ezi zinto zintathu zikhuselekile.Ukwahluka kweempawu zemathiriyeli kwenza iikomityi zineendlela ezahlukeneyo zokuvelisa kunye nembonakalo.

I-PET okanye i-PETE
Iindebe ezenziwePolyethylene terephthalate(PET, PETE)zicacile, ziyabengezela kwaye zomelele.Ziyakwazi ukumelana nomkhenkce ukuya kwi -22 ° F kunye nobushushu obungamelana ne-180 ° F. Zilungele ijusi, iziselo ezibandayo njl. Ngokuqhelekileyo zinenombolo"1" ngaphakathi kwesimboli yokubuyisela kunye ne-PET phantsi kwesimboli.

PP
Iikomityi zePolypropylene(PP) zi-semi-transparent, zibhetyebhetye kwaye ziyakwazi ukumelana nokuqhekeka.Zinendawo ephezulu yokunyibilika kwaye zinokuxhathisa ioli, utywala kunye neekhemikhali ezininzi.Zikhuselekile kakhulu xa zisetyenziselwa iziselo kunye nezinye iipakethi.Iikomityi zePP zingenziwa ngemibala eyahlukeneyo.Iikomityi zihlala zinenombolo" 5" ngaphakathi kwesimboli yokuphinda isetyenziswe kwaye "PP" amagama angena phantsi kwayo.

PS
Ngokuqhelekileyo kukho iindidi ezimbini zemathiriyeli ye-polystyrene esetyenziselwa ukwenza iikomityi kunye neeglasi: I-HIPS kunye ne-GPPS.Iikomityi ze-thermoformed zihlala zenziwe kwi-HIPS.Umbala wayo wokuqala unenkungu kwaye zinokwenziwa ngemibala eyahlukeneyo.Iikomityi zeHIPS ziqinile kwaye ziyaphuka.Ikomityi ye-PS ibhityile kunobunzima obufanayo bekomityi yePP.Iiglasi ezitofwayo zenziwe ngeGPPS.Iiglasi zikhanya kwaye zigqithisa ukukhanya okuphezulu.Iiglasi zeplastiki zilungele amaqela kunye nezinye iziganeko.Zingenziwa ngemibala eyahlukeneyo kwaye iiglasi zeplastiki ze-neon zilungile kumaqela asebusuku.Iikomityi zePS zihlala zinenombolo"6" ngaphakathi kwesimboli yokuphinda isetyenziswe kunye namagama "PS" phantsi kwayo.
