Izinto ezivuthiwe zamabhokisi epulasitiki zasemini ikakhulukazi i-polyethylene (pe) noma i-polypropylene (PP). Lezi zinto zokwakha zinokuqina okuhle, ukumelana komswakama, ukumelana kawoyela nokuqina, futhi kuphansi kakhulu ngezindleko, ngakho-ke zisetshenziswa kabanzi embonini yokupaka ukudla.
1. I-polyethylene (pe)
I-Polyethylene iyi-thermoplastic ejwayelekile enobutha obuhle nokumelana nomthelela. Ihlukaniswe ngezinhlobo ezahlukahlukene ezifana ne-- density polyethylene (LDPE) ne-High - density polyethylene (HDPE), ezisetshenziselwa ukwenza imikhiqizo ehlukahlukene yepulasitiki, kufaka phakathi amabhokisi okudla kwasemini. Amabhokisi wesidlo sasemini sasePolyethylene ngokuvamile anokubona okuhle, akhanya futhi akulula ukuwaphula, futhi alungele ukuthwala ukudla.
2. I-Polypropylene (PP)
I-Polypropylene iyi-semi - crystalline thermoplastic ene-high high ukumelana, amandla emishini kanye nokuqina kwamakhemikhali. Amabhokisi wesidlo sasemini se-polypropylene angamelana namazinga okushisa aphezulu, ngakho-ke ajwayele ukusetshenziselwa ukufakwa kokudla okudinga ukufudumala noma ama-microwave.
