His version of Plastic Bags included organic cellulose that could be moulded when heated and held its shape when cooled. Plastics are composed of polymers (large molecules consisting of repeat units called monomers.) The repeating units are either ethylene of ethene. Plastic bags are made come forth of one of three basic types; richly Density polyethylene (HDPE), Low density polyethylene (LDPE), or Linear low density polyethylene (LLDPE) . The thick calendered shopping bags are LLDPE while the thin grocery bags are HDPE. The major deviance between these materials is the degree of branching of the polymer chain. LLDPE bags substantiate unbranched bondage while LDPE have branched chains. ramose affects the strength and crystallinity; this is wherefore grocery bags are weaker and flimsier than shopping bags.
How do Plastic Bags affect the environment? Usually plastic bags are not habituated of properly and they end up being in the sea. In the water, plastic bags are often mistaken for ship of the line by wildlife and they try digesting the bag s and it blocks up their intestines, when th! is happens the animals eventually die and slit to crock up, they decompose faster than the plastic bags because bags take from 20-1000 long time to decompose, so the bags is released stand into the environment and another organism chow chow it. From my research, I have found pictures of a turtle having operating room because of the plastic bags in their digestive system; inside the bear they found a blue plastic bag and a...If you expect to get a full essay, order it on our website: OrderCustomPaper.com
