LLDPE or LDPE Tubing | Which is Better?

What is the Difference Between LDPE and LLDPE? Low Density Polyethylene (LDPE) and Linear Low Density Polyethylene (LLDPE) are both inexpensive polymers with widely favorable mechanical and chemical resistance properties. Tubing made from both polymers is broadly used, particularly for water, chemicals and gases.
