Plastic bụ ihe anyị na-ejikarị eme ihe kwa ụbọchị. Dị ka obere akpa, karama ụmụaka, karama ihe ọverageụverageụ, igbe nri ehihie, ihe mkpuchi plastik, nke buru ibu dị ka ihe nkiri ubi, arịa ụlọ, ngwa eletriki, mbipụta 3D, na ọbụna rọketi na agba, plastik niile bịara
Plastic bụ ngalaba dị mkpa nke ihe eji eme polymer, nwere ọtụtụ ụdị, nnukwu mkpụrụ na ngwa dị iche iche. Maka ụdị plastik dị iche iche, enwere ike ịkọwa ha dị ka ndị a:

2. Dị ka ụdị mmeghachi omume n'oge njikọ nke resin na plastik, enwere ike kewaa resin n'ime polymerized plastics na polycondensed plastics;
3. Dịka usoro nke resin macromolecules, enwere ike kewaa plastik n'ụdị abụọ: plastik amorphous na plastik crystalline;
4. Dabere na oke arụmọrụ na ngwa, a pụrụ ikewa plastik gaa na plastik izugbe, plastik injinia, na plastik pụrụ iche.
N'ime ha, a na-ejikarị plastik ndị nwere isi arụ ọrụ na ndụ anyị kwa ụbọchị. General-nzube plastik na-ezo aka plastik na nnukwu mmepụta olu, ọkọnọ buru ibu, ọnụahịa dị ala na nke kwesịrị ekwesị maka nnukwu ngwa. General-nzube plastik nwere ezi ịkpụzi processability, na nwere ike kpụrụ n'ime ngwaahịa maka nzube dị iche iche site na usoro dị iche iche. General-nzube plastik gụnyere polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), acrylonitrile / butadiene / styrene (ABS).
Oge a ka m ga - ekwu maka isi ihe eji eji polyethylene (PE). Polyethylene (PE) nwere nhazi magburu onwe ya ma jiri ihe eji eme ihe, bụ ihe a na-ejikarị eme ihe na resins synthetic, na ikike mmepụta ya nwere ogologo oge mbụ n'etiti ụdị plastic niile. Polyethylene resins tumadi gụnyere obere polyethylene (LDPE), linear low-density polyethylene (LLDPE), na akwa-polyethylene (HDPE).
A na-eji polyethylene eme ihe n'ọtụtụ mba, fim na-ejikwa ya eme ihe. Ọ na-ewe ihe dị ka 77% nke obere polyethylene na 18% nke polyethylene dị elu.
