      Bags containers bottles polyethylene
      Polyethylene consists of hydrocarbon chains with the most basic component being the ethylene molecule, consisting of 2 carbon and 4 hydrogen atoms. When ethylene molecules are combined together in straight or branched chains, polyethylene is formed. This process involves splitting the double bond between the 2 carbon atoms and creating a free radical to join to the next ethylene molecule. The macromolecules are not covalently joined, but are held together in a crystalline structure through intermolecular forces. The lower the number of side branches, the lower the crystallinity and hence the higher the density as can be observed in the differing properties for differing types of polyethylene.
