Which type of polyethylene is used to make Ziploc bags and folding tables. Concept introduction: When ethylene undergoes polymerization polyethylene is formed. In absence of Ziegler-Natta catalyst ethylene polymerizes to give polyethylene that has about 20 branches per thousand carbon atoms. This has relatively low density giving rise to low-density polyethylene (LDPE). In presence of Ziegler-Natta catalyst ethylene polymerizes to give polyethylene that has about five branches per thousand carbon atoms. This has relatively high density giving rise to high-density polyethylene (HDPE). The density difference makes the polyethylene useful for making many materials. To identify : To identify which polyethylene will be used to make Ziploc bags and folding tables.

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
