Ol plastik prodak i stap long olgeta hap insait long laip bilong yumi long olgeta de, tasol ol i gat kain kain samting. Ol kain kain plastik samting i soim bikpela senis long wok, yusim, na sefti. Sapos yu kliagut long ol dispela samting i narapela, dispela inap helpim yu long makim na yusim gut ol plastik samting.
Namba wan, ol plastik we planti manmeri i save yusim i ken bruk i go long tupela lain: ol 'thermoplastics' na ol 'thermosetting' plastik. Ol 'thermoplastics' (olsem 'polyethylene' (PE), 'polypropylene' (PP), na 'polystyrene' (PS)) i save kamap malumalum na senis taim ol i hatim na kamap strong gen taim ol i kol, na dispela i mekim ol i ken kamap gen na ol i gutpela long ol samting we yu ken tromoi na i stap longpela taim olsem ol paket na ol kontena. Ol plastik we i save strongim hat (olsem ol 'phenolic resins' na 'epoxy resins') ol i no inap long melt gen taim ol i kamap strong. Ol i gat bikpela strong bilong sakim hat na planti taim ol i save yusim long ol wok we i nidim longpela taim, olsem 'electrical insulation' na ol hap bilong kar.
Namba tu, ol kemikel samting na sefti bilong ol kain kain plastik i save senis tru. Olsem, ol i save yusim 'polyethylene terephthalate' (PET) long ol botol bilong dring, tasol sapos yu yusim gen inap longpela taim, dispela inap long rausim ol samting nogut. Hai-densiti polyethylene (HDPE) em i no inap bagarap na i no gat posin, olsem na em i gutpela long ol bokis na paip bilong putim ol samting. Polyvinyl chloride (PVC) i gat ol 'plasticizer' na em inap long rausim ol samting nogut taim em i stap long bikpela hat o oil, olsem na ol i no save yusim long putim ol kaikai long ol paket.
Na tu, ol samting bilong ol plastik i save makim tu wok bilong en. Polycarbonate (PC) i gat bikpela 'transparency' na strongpela 'impact resistance' na planti taim ol i save yusim long ol 'eyeglass lens' na ol samting bilong lukautim ai. Polytetrafluoroethylene (PTFE, ol i save kolim tu olsem Teflon) em i no inap long bagarapim ol marasin na ol i save yusim long ol non-stick pan coating.
Long sotpela tok, ol samting i narapela long ol plastik prodak i no kamap long kain samting tasol, tasol tu long ol rot bilong prosesim, strong bilong san, strong bilong ol kemikel, na wok bilong envairomen. Ol manmeri i mas makim stretpela plastik prodak bihainim ol nid bilong ol na lukluk gut long ol tambu bilong yusim bilong en long mekim gutpela na sastenebiliti.
