HDPE
Maualuga-loloto polyethylene (HDPE) poʻo polyethylene maualuga-maualuga (PEHD) o se polyethylene thermoplastic faia mai suauʻu. O nisi taimi e taʻua o le "alkathene" poʻo le "polythene" pe a faʻaaogaina mo paipa. Faatasi ai ma le maualuga malosi-i-density fua faatatau, HDPE o loʻo faʻaaogaina i le gaosia o palasitika fagu, paʻu-tetee paipa, geomembranes, ma palasitika laupapa. HDPE e masani ona toe gaosia, ma e iai le numera "2" o lona resin faʻailoga code (na taʻua muamua o le toe faʻailoga).

PET
Polyethylene terephthalate (o nisi taimi e tusia poly (ethylene terephthalate)), e masani lava faapuupuuina PET, PETE, pe le faʻaaogaina PETP po PET-P, o le taatele masani termoplastic polimini resin o le aiga polyester ma o lo o faʻaaogaina i alava mo lavalava, pusa mo vai ma meaʻai, thermoforming mo gaosiga, ma i le tuʻufaʻatasi ma tioata fiber mo inisinia resin.

PP
Polypropylene (PP), ua faʻaigoaina foʻi polypropene, o se polyopopastic thermoplastic faʻaaogaina i le tele o ituaiga o talosaga e aofia ai afifiina ma faʻaigoaina, ie (ie, maea, ofuvae vevela ma kapeti), pepa tusi, vaega palasitika ma pusa faʻaaoga faʻaaoga eseese o ituaiga eseese, fale suesue mea faigaluega, masini leotele, vaega tisaini mea, ma polimerota tupe. O se faʻaopopo faʻapipiʻi ua faia mai le monomer propylene, o loʻo gaoa ma e le masani ai le tetee atu i le tele o vailaʻau solvents, faʻavae ma le maualuga.
