HDPE vs. LDPE: What's the Difference? - Polybags
LDPE is less dense because of the increased space between the few branches that form during polymerization, which makes it incredibly flexible. LDPE also has better clarity than more dense polyethylene materials, so it can be used as an attractive packaging option that lets customers easily see what's inside.

Linear Low Density Polyethylene - POLYMER ACADEMY.com
LLDPE is a substantially linear polymer (polyethylene), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain of olefins. Linear low-density polyethylene differs structurally from predictable low-density polyethylene (LDPE) because of the absence of long chain branching. Processing & Properties:

What is the Difference Between HDPE LDPE and LLDPE
The term LDPE stands for low density polyethylene. It is a thermoplastic material. The monomer of this polymer material is ethylene. LDPE was first produced in 1933 by Imperial Chemical Industries using the process of high pressure free radical polymerization. This is the most common method of production for LDPE even today.

LDPE vs HDPE - University of Texas at Austin
LD ranges around 0.91-0.93 g/mL while HD is in the range of 0.94-0.97 g/mL. Believe it or not, that is enough of a difference that these plastics can be physically separated based on their densities in float tanks. LDPE is a softer, more flexible plastic than HDPE. It melts at a lower temperature (110 °C vs 131 °C).
