Themakapu apulasitiki otayikakawirikawiri amapangidwa kuchokeraPolyethylene terephthalate (PET kapena PETE)Polypropylene (PP) ndi Polystyrene (PS).Zida zonse zitatuzi ndi zotetezeka.Kusiyanasiyana kwazinthu izi kumapangitsa makapu kukhala ndi njira zosiyanasiyana zopangira komanso mawonekedwe.

PET kapena PETE
Makapu opangidwa kuchokeraPolyethylene terephthalate (PET, PETE)zomveka bwino, zosalala zonyezimira komanso zolimba.Iwo amaundana kugonjetsedwa ndi -22 ° F ndi kutentha kugonjetsedwa ndi 180 ° F. Iwo ndi abwino kwa madzi, zakumwa zoziziritsa kukhosi etc. Nthawi zambiri amakhala ndi nambala"1" mkati mwa chizindikiro chobwezeretsanso pamodzi ndi PET pansi pa chizindikiro.

PP
Makapu a polypropylene(PP) ndi owoneka bwino pang'ono, osinthika komanso osasunthika.Ali ndi malo osungunuka kwambiri ndipo amatha kukana mafuta, mowa ndi mankhwala ambiri.Ndizotetezeka zomwe zimagwiritsidwa ntchito pazakumwa ndi mapaketi ena.Makapu a PP amatha kupangidwa mumitundu yosiyanasiyana.Makapu nthawi zambiri amakhala ndi nambala" 5" mkati mwa chizindikiro chobwezeretsanso ndipo mawu "PP" amabwera pansi pake.

PS
Nthawi zambiri pamakhala mitundu iwiri ya zida za polystyrene zomwe zimagwiritsidwa ntchito popanga makapu ndi magalasi: HIPS ndi GPPS.Makapu a thermoformed nthawi zambiri amapangidwa kuchokera ku HIPS.Ndi mtundu wapachiyambi ndi chifunga ndipo zikhoza kupangidwa mu mitundu yosiyanasiyana.Makapu a HIPS ndi olimba komanso ophwanyika.Chikho cha PS ndi chochepa kwambiri kuposa chikho cha PP cholemera chomwecho.Magalasi ojambulidwa amapangidwa kuchokera ku GPPS.Magalasiwo ndi opepuka komanso otumiza kuwala kwambiri.Magalasi apulasitiki ndi abwino kwa maphwando ndi zochitika zina.Zitha kupangidwa mumitundu yosiyanasiyana ndipo magalasi apulasitiki a neon ndiabwino pamaphwando ausiku.Makapu a PS nthawi zambiri amakhala ndi nambala"6" mkati mwa chizindikiro chobwezeretsanso ndi mawu oti "PS" pansi pake.
